Module: RestApi

Recommended Posts

@pmichaelis If the error is thrown in line 131 it's likeley there is an error with the JWT Authorization. Maybe the Token you're submitting is not valid, maybe something else. Hard to tell with the little information you provided.

Oh, just noticed you already mentioned the JWT Auth… 🙂 Probably the error is produced in those 4 lines:

$secret = wire('modules')->RestApi->jwtSecret;
$token = str_replace('Bearer', '', $authHeader);
$token = trim($token);
$decoded = JWT::decode($token, wire('modules')->RestApi->jwtSecret, array('HS256'));

if the secret is in your config and you didn't change it, I'd check if the token gets transmitted properly with the request.

@thomasaull It seems that the authorisation headers are not present.

Added the following line to the htaccess:

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

auth headers are stored in following variable

$_SERVER['REDIRECT_HTTP_AUTHORIZATION'];

Please don't ask why.

@pmichaelis I'm gonna ask anyway: Why? 😉

Seems like a weird server config, but I could add this to the variables the module checks by default.

Here is the final cleaned-up and more secure 'api' template that I am using in between the RestApi router and ProCache, perhaps it can be of some help:

 

I ran into issues with a slow server using this method, where wireHttp would already resolve a result while RestApi was still running.
So with help from my co-worker @harmvandeven we came up with a more stable version, with some more redundancy: 
 

<?php

/*

    api.php, a simple PW template to fill the gap between the RestApi and ProCache modules
    v2

    @author: @eelkenet, with help from @harmvandeven & @ryan

    1. Create a template called 'api' and set it up using the following settings:
    - Allow URL segments
    - Allow guests to view the page
    - Set the Content-Type to application/json
    - Make sure to NOT Prepend or Append any files

    2. Add a page using this template and allow ProCache to run its magic

*/

$timeout = 600;
$maxAttempts = 10;

// Pre-check for unwanted symbols
if (strpos($input->urlSegmentStr(), '.') !== false) {
    throw new Wire404Exception();
}

// Build request URL
$endpoint = $modules->get("RestApi")->endpoint;
$url = $input->scheme() . "://" . $config->httpHost . "/" . $endpoint ."/" . $input->urlSegmentStr();

$http = new WireHttp();

// Set a high timeout, to deal with a slow server
$http->setTimeout($timeout);

// Get the HTTP status of the page, to make sure it exists in the first place
$status = $http->status($url);

// If the page exists, or possibly redirects to valid content
if ($status >= 200 && $status < 400) {

    $result = false;
    $attempt = 0;

    // If the result isn't a string, something went wrong
    while(gettype($result) !== "string" && $attempt++ < $maxAttempts) {

        $result = $http->get($url);
        if ($attempt > 1) wire()->log->message("Loading content at $url, attempt $attempt: " . gettype($result));
    }

    // Double check if the data is a string..
    if (gettype($result) === "string"){

        // .. And check if it can be decoded, if so: return the data and thus cache it
        if (json_decode($result) !== NULL) return $result;

        // If it cannot be decoded: throw exception (don't cache it)
        throw new WireException("Found the data at $url, but it could not be decoded. Please check your API output!");
    }

    // Throw exception if data could not be loaded in time (don't cache it)
    throw new WireException("Found the data at $url, but could not load it in time, after $attempt attempts. Result has type: " . gettype($result));

}

// Throw generic exception if the requested page was not found or there was another error
throw new WireException("Failed to load the content at: $url, with HTTP status: " . $status);

Hi

I've just installed this module (processwire version 3.0.123) but I can't get anything off a connection. I tried a clean install without any modules activated and have the some problem. Is there anything that has to be installed to be able to get a response? I'm developing on a local environment of xampp and tried it on a mac os environment with mamp aswell.

I tested it on a production environment (online hosting) and there it is working. I'm guessing it has something to do with the local servers. Anybody has an idea what should be activated?

Thanks in advance

@thibaultvdb It's a bit difficult to help from here. One thing you could try is to go through the code in Router.php and return or exit early to find out until where the code runs. The main functions are "go()" and "handle()". Another idea is to compare php settings between your hosted and local environment with "phpinfo()". If you can isolate the issue it's much easier to help.

The main functions are all going like they should. I tried comparing the php info like you said but those files are huge so hard to compare them and find out what is missing/wrong. Is there a localhost software you recommend that is working? Friends that have mamp pro don't have the issue but using mamp/xampp does give me the 404. It's strange that I don't get errors, only a 404 page.

If I can provide you anything please let me know since serverside issue's aren't my best area of working.

@thibaultvdb 

I think that by default on XAMPP your ProcessWire installation is in a subdir, and I bet that the module is giving you as api endpoint something like : /subdir/api instead of the /api endpoint. 

You should ask your friends to help you to setup your localhost environment to use a domain like  http://mylocalwebsite.local

To get started, you can follow the second answer here https://stackoverflow.com/questions/16229126/using-domain-name-instead-of-localhost-in-with-https-in-xampp

or follow this tutorial to use AcrylicDNS (the best solution IMO, do not be afraid, it's really easy to setup) https://www.ottorask.com/blog/automated-apache-virtual-hosts-on-windows/

 

Good luck.

@thibaultvdb If what @flydev says is the case and you're trying to access your website inside a subdirectory you could also try to adjust the path for the api in the module settings. Maybe it'll work 🙂

@flydev I must say you are the savior of the day. The reason was indeed that xampp is putting "localhost" in front of the site url.
In my case this was "localhost/sitename" the RestApi module probably didn't understand this sitename url what gave me 404-pages all the time.

@thomasaull You mentioned that maybe this could be fixed through the settings of the module. Could you give an example of a path?
Maybe it's usefull to add a option to the module or something that notifies the user if it is using localhost or to automatically prefix this with localhost? I don't think I will be the only one that uses the localhost prefix 😛 

Thanks for the help already! Hopefully there is a possibility to handle this in the settings so I don't have to use these virtual hosts. Or maybe look at the processwire config? The processwire handles this localhost prefix perfectly.

@thibaultvdb In the module settings there is an input for "API Endpoint" — can you try to change the value there to "localhost/api" and report back if this works for you?

@thomasaull changing the api endpoint didn't solve it (I tried a few things already). I solved it by using the virtual host for this project but for the future and others a localhost sollution would be lovely!
If I can provide anything more, please tell me!

@thibaultvdb I need to check this, since I think (when I remember it properly) I put this option in specifically for this use-case. If you want to fiddle around try making it work or you know/want to figure out how ProcessWire does this automatically feel free 🙂 Otherwise I can't really make any promise when I'm going to be able to look into this

Hello,
I have a clean blank install of latest dev version of Processwire. When I install your module, the backend stops working.

@Hurme

Did you check your server error logs for hints? Or site/assets/logs/ ?

First of all, you could try to delete everything in site/assets/cache/modules/. 

If that doesn't work, rename the REST API module: prepend a dot (.modulename).

@dragan Hi, I've left the office and wont be back until next week, but I'll see if deleting the cache has any effect. There were no errors in the log files, just your usual "Saved module X". Of course deleting the module itself resolves the crashing issue, but then you can't really use the module.

Recently a user of this module had the problem that some multi-language fields weren't working correctly.kno After some investigation I discovered, that the hook this module uses (it's a "before ProcessPageView::execute") kicks in to early for the multi-language plugins to be ready. Does anyone knows of a hook, which can do something similar (basically take over the default routing of ProcessWire) while still have the other modules loaded?

One alternative approach for this specific problem would be to not trigger the module via a hook but with an own template and page like the old RestApiProfile did. A couple of benefits would come for free aswell (these are my assumptions, not tested yet):

  • ProCache should work without any workarounds
  • Multi-Language works
  • Websites in subdirectories (if working in ProcessWire in general) should work
  • site profile export would work if the /api folder lives in /templates by default

Any potential downsides I'm not seeing yet? Thoughts?

      ---- INITIAL POST FROM 2019-05-25 ----
      I wanted to let you know that I am currently working on a new ProcessWire module that fully integrates the Snipcart Shopping Cart System into ProcessWire. (this is a customer project, so I had to postpone the development of my other module GroupMailer).
      The new module SnipWire offers full integration of the Snipcart Shopping Cart System into ProcessWire.
      Here are some highlights:
      simple setup with (optional) pre-installed templates, product fields, sample products (quasi a complete shop system to get started immediately) store dashboard with all data from the snipcart system (no change to the snipcart dashboard itself required) Integrated REST API for controlling and querying snipcart data webhooks to trigger events from Snipcart (new order, new customer, etc.) multi currency support self-defined/configurable tax rates etc. Development is already well advanced and I plan to release the module in the next 2-3 months.
      I'm not sure yet if this will be a "Pro" module or if it will be made available for free.
      I would be grateful for suggestions and hints!
      (please have a look at the screenshots to get an idea what I'm talking about)

      Update 31.7.2019: AdminBar is now maintained by @teppo. Modules directory entry has been updated, as well as the "grab the code" link below.
      ***
      Latest screencast: http://www.screencas...73-ab3ba1fea30c
      Grab the code: https://github.com/teppokoivula/AdminBar
      ***
      I put this Adminbar thingy (from here: http://processwire.c...topic,50.0.html) to modules section and to it's own topic.
      I recorded quick and messy screencast (really, my first screencast ever) to show what I have made so far. You can see it from here: http://www.screencas...18-1bc0d49841b4
      When the modal goes off, I click on the "dark side". I make it so fast on screencast, so it might seem a little bit confusing. Current way is, that you can edit, go back to see the site (without saving anything), continue editing and save. After that you still have the edit window, but if you click "dark side" after saving, then the whole page will be reloaded and you see new edits live.
      I am not sure if that is best way: there are some strengths in this thinking, but it is probably better that after saving there shouldn't be a possibility to continue editing. It might confuse because then if you make edits, click on dark side -> *page refresh* -> You lose your edits.
      ***
      When I get my "starting module" from Ryan, I will turn this into real module. Now I had to make some little tweaks to ProcessPageEdit.module (to keep modal after form submits). These probably won't hurt anything:
      if($this->redirectUrl) $this->session->redirect($this->redirectUrl); if(!empty($_GET['modal'])) $this->session->redirect("./?id={$this->page->id}&modal=true"); // NEW LINE else $this->session->redirect("./?id={$this->page->id}");   and...
      if(!empty($_GET['modal'])) { $form->attr('action', './?id=' . $this->id . '&modal=true'); } else { $form->attr('action', './?id=' . $this->id); // OLD LINE }

      Jumplinks for ProcessWire
      Release: 1.5.54
      Composer: rockett/jumplinks
      Jumplinks is an enhanced version of the original ProcessRedirects by Antti Peisa.
      The Process module manages your permanent and temporary redirects (we'll call these "jumplinks" from now on, unless in reference to redirects from another module), useful for when you're migrating over to ProcessWire from another system/platform. Each jumplink supports wildcards, shortening the time needed to create them.
      Unlike similar modules for other platforms, wildcards in Jumplinks are much easier to work with, as Regular Expressions are not fully exposed. Instead, parameters wrapped in curly braces are used - these are described in the documentation.
      Under Development: 2.0, to be powered by FastRoute
      As of version 1.5.0, Jumplinks requires at least ProcessWire 2.6.1 to run.
      View on GitLab
      Download via the Modules Directory
      Read the docs
      Features
      The most prominent features include:
      Basic jumplinks (from one fixed route to another) Parameter-based wildcards with "Smart" equivalents Mapping Collections (for converting ID-based routes to their named-equivalents without the need to create multiple jumplinks) Destination Selectors (for finding and redirecting to pages containing legacy location information) Timed Activation (activate and/or deactivate jumplinks at specific times) 404-Monitor (for creating jumplinks based on 404 hits) Additionally, the following features may come in handy:
      Stale jumplink management Legacy domain support for slow migrations An importer (from CSV or ProcessRedirects) Feedback & Feature Requests
      I’d love to know what you think of this module. Please provide some feedback on the module as a whole, or even regarding smaller things that make it whole. Also, please feel free to submit feature requests and their use-cases.
      Note: Features requested so far have been added to the to-do list, and will be added to 2.0, and not the current dev/master branches.
      Open Source

      Jumplinks is an open-source project, and is free to use. In fact, Jumplinks will always be open-source, and will always remain free to use. Forever. If you would like to support the development of Jumplinks, please consider making a small donation via PayPal.
      Enjoy! :)

      I've spent the last while experimenting with srcset implementation - and PageimageSrcset is the result:
      PageimageSrcset
      Provides configurable srcset and sizes properties/methods for Pageimage.
      Overview
      The main purpose of this module is to make srcset implementation as simple as possible in your template code. It does not handle images rendered in CKEditor or similar fields.
      For an introduction to srcset and sizes, please read this Mozilla article about responsive images.
      Pageimage::srcset()
      // The property, which uses the set rules in the module configuration $srcset = $image->srcset; // A method call, using a set rules string // Delimiting with a newline (\n) would also work, but not as readable $srcset = $image->srcset("320, 480, 640x480 768w, 1240, 2048 2x"); // The same as above but using an indexed/sequential array $srcset = $image->srcset([ "320", "480", "640x480 768w", "1240", "2048 2x", ]); // The same as above but using an associative array // No rule checking is performed $srcset = $image->srcset([ "320w" => [320], "480w" => [480], "768w" => [640, 480], "1240w" => [1240], "2x" => [2048], ]); // Use the default set rules with portrait images generated for mobile/tablet devices $srcset = $image->srcset(true); // Return the srcset using all arguments $srcset = $image->srcset("320, 480, 640x480 768w, 1240, 2048 2x", [ "portrait" => "320, 640", ]); // The set rules above are a demonstration, not a recommendation! Image variations are only created for set rules which require a smaller image than the Pageimage itself. On large sites this may still result in a lot of images being generated. If you have limited storage, please use this module wisely.
      Portrait Mode
      In many situations, the ratio of the image does not need to change at different screen sizes. However, images that cover the entire viewport are an exception to this and are often the ones that benefit most from srcset implementation.
      The main problem with cover images is that they need to display landscape on desktop devices and portrait when this orientation is used on mobile and tablet devices.
      You can automatically generate portrait images by enabling portrait mode. It is recommended that you use this in combination with Pageimage::focus() so that the portrait variations retain the correct subject.
      The generated variations are HiDPI/Retina versions. Their height is determined by the portrait ratio (e.g. 9:16). Variations are always generated, regardless of whether the original image is smaller. Upscaling is disabled though, so you may find that some variations are actually smaller than they say they are in their filename.
      The sizes attribute should be used when portrait mode is enabled. Pageimage::sizes will return (orientation: portrait) and (max-width: {maxWidth}px) 50vw by default, which handles the use of these images for retina devices. The maximum width used in this rule is the largest set width.
      Pageimage::sizes()
      There is no option to configure default sizes because in most cases 100vw is all you need, and you do not need to output this anyway as it is inferred when using the srcset attribute. You can use the method for custom sizes though:
      // The property $sizes = $image->sizes; // Returns 100vw in most cases // Returns '(orientation: portrait) and (max-width: {maxWidth}px)50vw' if portrait mode enabled // A method call, using a mixture of integer widths and media query rules // Integer widths are treated as a min-width media query rule $sizes = $image->sizes([ 480 => 50, "(orientation: portrait) and (max-width: 640px)" => 100, 960 => 25, ]); // (min-width: 480px) 50vw, (orientation: portrait) and (max-width: 640px) 100vw, (min-width: 960px) 25vw // Determine widths by UIkit 'child-width' classes $sizes = $image->sizes([ "uk-child-width-1-2@s", "uk-child-width-1-3@l", ]); // (min-width: 640px) 50vw, (min-width: 1200px) 33.33vw // Determine widths by UIkit 'width' classes $sizes = $image->sizes([ "uk-width-1-2@m", "uk-width-1-3@xl", ]); // (min-width: 960px) 50vw, (min-width: 1600px) 33.33vw // Return the portrait size rule $sizes = $image->sizes(true); // (orientation: portrait) and (max-width: {maxWidth}px) 50vw // The arguments above are a demonstration, not a recommendation! Pageimage::render()
      This module extends the options available to this method with:
      srcset: When the module is installed, this will always be added, unless set to false. Any values in the formats described above can be passed. sizes: Only used if specified. Any values in the formats described above can be passed. uk-img: If passed, as either true or as a valid uk-img value, then this attribute will be added. The srcset attribute will also become data-srcset. Please refer to the API Reference for more information about this method.
      // Render an image using the default set rules echo $image->render(); // <img src='image.jpg' alt='' srcset='{default set rules}'> // Render an image using custom set rules echo $image->render(["srcset" => "480, 1240x640"]); // <img src='image.jpg' alt='' srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w'> // Render an image using custom set rules and sizes // Also use the `markup` argument echo $image->render("<img class='image' src='{url}' alt='Image'>", [ "srcset" => "480, 1240", "sizes" => [1240 => 50], ]); // <img class='image' src='image.jpg' alt='Image' srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w' sizes='(min-width: 1240px) 50vw'> // Render an image using custom set rules and sizes // Enable uk-img echo $image->render([ "srcset" => "480, 1240", "sizes" => ["uk-child-width-1-2@m"], "uk-img" => true, ]); // <img src='image.jpg' alt='' data-uk-img data-srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w' sizes='(min-width: 960px) 50vw'> // Render an image using portrait mode // Default rule sets used: 320, 640, 768, 1024, 1366, 1600 // Portrait widths used: 320, 640, 768 // Original image is 1000px wide // Not possible to use portrait mode and custom sets or portrait widths in render() // Sizes attribute automatically added echo $image->render(["srcset" => true]); // <img src='image.jpg' alt='' srcset='image.320x569-srcset-hidpi.jpg 320w, image.640x1138-srcset-hidpi.jpg 640w, image.768x1365-srcset-hidpi.jpg 768w, image.jpg 1024w' sizes='(orientation: portrait) and (max-width: 768px) 50vw'> Configuration
      To configure this module, go to Modules > Configure > PageimageSrcset.
      Set Rules
      These are the default set rules that will be used when none are specified, e.g. when calling the property: $image->srcset.
      Each set rule should be entered on a new line, in the format {width}x{height} {inherentwidth}w|{resolution}x.
      Not all arguments are required - you will probably find that specifying the width is sufficient for most cases. Here's a few examples of valid set rules and the sets they generate:
      Set Rule Set Generated Arguments Used 320 image.320x0-srcset.jpg 320w {width} 480x540 image.480x540-srcset.jpg 480w {width}x{height} 640x480 768w image.640x480-srcset.jpg 768w {width}x{height} {inherentwidth}w 2048 2x image.2048x0-srcset.jpg 2x {width} {resolution}x How you configure your rules is dependent on the needs of the site you are developing; there are no prescriptive rules that will meet the needs of most situations. This article gives a good overview of some of the things to consider.
      When you save your rules, a preview of the sets generated and an equivalent method call will be displayed to the right. Invalid rules will not be used, and you will be notified of this.
      Portrait Mode
      Set Widths
      A comma limited list of widths to create HiDPI/Retina portrait variations for.
      Crop Ratio
      The portrait ratio that should be used to crop the image. The default of 9:16 should be fine for most circumstances as this is the standard portrait ratio of most devices. However, you can specify something different if you want. If you add a landscape ratio, it will be switched to portrait when used.
      Any crops in the set rules ({width}x{height}) are ignored for portrait mode variations as this ratio is used instead.
      UIkit Widths
      If your website theme uses UIkit, you can pass an array of UIkit width classes to Pageimage::sizes to be converted to sizes. The values stored here are used to do this. If you have customised the breakpoints on your theme, you should also customise them here.
      Please note that only 1- widths are evaluated by Pageimage::sizes, e.g. uk-width-2-3 will not work.
      Remove Variations
      If checked, the image variations generated by this module are cleared on Submit. On large sites, this may take a while. It makes sense to run this after you have made changes to the set rules.
      Image Suffix
      You will see this field when Remove Variations is checked. The value is appended to the name of the images generated by this module and is used to identify variations. You should not encounter any issues with the default suffix, but if you find that it conflicts with any other functionality on your site, you can set a custom suffix instead.
      Debug Mode
      When this is enabled, a range of information is logged to pageimage-srcset.
      PageimageSrcsetDebug.js is also added to the <head> of your HTML pages. This will console.log a range of information about the images and nodes using srcset on your page after a window.onresize event is triggered. This can assist you in debugging your implementation.
      The browser will always use the highest resolution image it has loaded or has cached. You may need to disable browser caching to determine whether your set rules are working, and it makes sense to work from a small screen size and up. If you do it the other way, the browser is going to continue to use the higher resolution image it loaded first.
