[SOLVED] Sending a JSON POST request to REST API in PHP

Sending a JSON POST request to REST API in PHP

I need to make a POST request using a JSON object as the body. Both of these methods are giving me HTTP 500 server errors. Is there anything glaringly wrong with my code? Be gentle... I've tried several methods including

$checkfor = ("'serverId':'Server','featureId':'Feature','propertyId':'Property'");
    $checkforJson = json_encode($checkfor);
    $uri = "http://localhost:8080/v1/properties";
    $response = \Httpful\Request::post($uri)
    ->method(Request::post)
    ->withoutStrictSsl()
    ->expectsJson()
    ->body($checkforJson)
    ->send();
    pre($response);

Which uses the HTTPful resource. And I have tried using cURL

$service_url = "http://localhost:8080/v1/properties";

   // Initialize the cURL
   $ch = curl_init($service_url);

   // Set service authentication

   // Composing the HTTP headers     
   $body = array();
   $body[] = '"serverId" : "Server"';
   $body[] = '"featureId" : "Feature"';
   $body[] = '"propertyId" : "Property"';
   $body = json_encode($body);

   $headers = array();
   $headers[] = 'Accept: application/xml';
   $headers[] = 'Content-Type: application/xml; charset=UTF-8';

   // Set the cURL options
   curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
   curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
   curl_setopt($ch, CURLOPT_POST, TRUE);
   curl_setopt($ch, CURLOPT_VERBOSE, 1);
   curl_setopt($ch, CURLOPT_HEADER, TRUE);
   curl_setopt($ch, CURLINFO_HEADER_OUT, true);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

   curl_setopt($ch, CURLOPT_TIMEOUT, 15);

   // Execute the cURL
   $data = curl_exec($ch);

   // Print the result
   pre($data);

Solution

Your json_encode requires an array.

It should look like this

<?php

$checkfor = ([
    'serverId'=>'Server',
    'featureId'=>'Feature',
    'propertyId'=>'Property'
]);

$checkforJson = json_encode($checkfor);
var_dump($checkforJson); // this will now work

For better understanding read doc

UPDATE I also notice on the curl script, your array needs fixed again

 $body['serverId'] = 'Server';

and dont json encode the post fields afterwards, it takes an array.
