input get / post inside of process module

[pwFoo]

I try to get POST data inside of my process module. Post request is sent by ajax with payload.

 

But $this->input->post() or $_POST is empty here?

    public function executeSubscribe() {
        // get subscription from client and save to user / db
        //$array = array("me" => 'you'); // works fine! Can output with console.log at client side
        //$array = $this->input->post('subscription'); // empty
		//$array = $this->input->post(); // empty
		//$array = (array) $this->input->post(); // empty
		//$array = $_POST; // empty
		$array = (array) $_POST; // empty
        $this->render($array);
    }

    protected function render($out) {
        header('Content-Type: application/json');
        echo json_encode($out);
        exit();
    }

I tried the post url with and without slash (I know the topics about ajax, post and trailing slash), but POST data is empty every time. Is it process module related? GET works fine in "execute()" method.

It's fetch() related...

fetch(subscribeUrl, {
                    method: 'post',
                    credentials: 'same-origin',
                    headers: { 'Content-type': 'application/json' },
                    body: JSON.stringify({ subscription: subscription })
                })

Change content type...

fetch(subscribeUrl, {
                    method: 'post',
                    credentials: 'same-origin',
                    //headers: { 'Content-type': 'application/json' },
                    headers: { 'Content-Type': 'application/x-www-form-urlencoded'},
                    body: JSON.stringify({ subscription: subscription })
                })

Searched for a PW / PHP issue and missed the needed Content-Type to get $_POST populated ?

Works fine with FormData object and without set Content-Type Header...

    var body = new FormData();
    body.append("name", "Bob");
    body.append("age", 27);

    fetch("http://127.0.0.1/fetch.php", {
        method: "post",
        body: body
    }).then(function(response) {
        console.log(response);
        return response.JSON();
    }).then(function(result) {
        console.log(result);
    });

<?php
$res = $_POST["name"];
print_r($res);
die();
