I am trying to connect to an API which is based on JSON-RPC 2.0. As i am new to this im not sure if im coding this correctly because all I am recieving is an error.
Can anyone give me a brief explanation on how to connect to API in PHP?
<?php
header('Content-Type: application/json');
//check if you have curl loaded
if(!function_exists("curl_init")) die("cURL extension is not installed");
$url = 'xxxxxxxxx';
$data = array(
"operator_id" => "xxxx",
"login" => "xxxx",
"password" => "xxxx",
);
$curl_options = array(
CURLOPT_URL => $url,
CURLOPT_HEADER => 0,
CURLOPT_NOBODY => true,
CURLOPT_POSTFIELDS => $data,
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_TIMEOUT => 0,
CURLOPT_SSL_VERIFYPEER => 0,
CURLOPT_FOLLOWLOCATION => TRUE,
CURLOPT_ENCODING => 'gzip,deflate',
CURLINFO_HEADER_OUT => true,
);
$ch = curl_init();
curl_setopt_array($ch, $curl_options);
$output = curl_exec($ch);
curl_close($ch);
$arr = json_decode($output,true);
echo ($output);
?>
The response i am recieving is this: {"jsonrpc":"2.0","error":{"code":-32600,"message":"Invalid request"},"id":null}
The response i should be recieving if successful login is: {"jsonrpc":"2.0","result":true,"error":null,"id":1,"ts":1368533487}

You're not sending a JSON-RPC request at all.
The request must be a JSON body, so you must json_encode the data before passing it to CURLOPT_POSTFIELDS.
The posted json must have the keys method
, params
, id
, and jsonrpc
(the last should be set to "2.0"). Your data would go into params
. The id
can be set to whatever, but without it you shouldn't get a response at all.
It is a quite simple format. See the specification at http://www.jsonrpc.org/specification
