Codeigniter 3.1.8 JSON Post fails - pigfox - 05-12-2018
Hello Community,
I am attempting a JSON POST request to a controller.
The header is:
Code:
[{"key":"Content-Type","value":"application/json"}]Code:
{"user":1}Code:
public function authorize(){
echo 'Line 37';//Works perfectly
print_r($this->input->raw_input_stream);//NULL
print_r(json_decode($this->input->raw_input_stream));//NULL
print_r(json_decode(file_get_contents('php://input')));//NULL
print_r(json_decode(trim(file_get_contents('php://input')), true));//NULL
print_r(json_decode(file_get_contents("php://input"), true));//file_get_contents(): Invalid php:// URL specified
}I am using Postman to make the request.
Any clue?

It looks okay to me...
Make sure that file_get_contents are activated by trying it on another resource. ->raw_input_stream utilizes that function.
PHP Code:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Postman extends CI_Controller {
public function index()
{
if( $this->input->is_ajax_request() )
{
$json = $this->input->raw_input_stream;
$json = json_decode($json);
/**
$json now looks like
stdClass Object
(
[user] => 1
)
Access it like
echo $json->user;
**/
// Process json...
// Data to send back
$data = array('success' => 'true');
// Send back json
$this->output
->set_content_type('application/json')
->set_output(json_encode($data));
}
}
}
Postman settings:
Content-Type: application/json
X-Requested-With: xmlhttprequest

According to my host: I can confirm that file_get_contents and allow_url_fopen are enabled.
Then I tried your suggestion.
Code:
public function authorize(){
if($this->input->is_ajax_request()) {
echo "This is an Ajax request\n";
$json = json_decode($this->input->raw_input_stream);
var_dump($json);//NULL
var_dump(json_decode(trim(file_get_contents('php://input')), true));//NULL
}
}I am also using the headers you suggested, see screen shot.
Any other ideas?

Have you tried grabbing another source/website with file_get_contents() to confirm it's actually activated?
Have you tried making a POST without https? In case your Cross-Origin Resource Sharing (CORS) are set wrong. Don't know if this actually apply to Postman thought.
Do you have the latest Codeigniter?
Do you have the latest PHP version? (7.1 or 7.2)

My PHP version is .7.0.28
Codeigniter version is 3.1.8
The following code snippet works.
PHP Code:
<?
var_dump(json_decode(trim(file_get_contents('php://input')), true));
?>Posting {"user":1} gives me:
array(1) {
["user"]=>
int(1)
}
