Send JSON HTTP query without CURL - php

Question

Can anyone help with the following
I'm trying to make a JSON request to a RESTful API. The code below is kindly shared by Wes Furlong
The code seems to be able to decode to JSON fine but sends as a URL encoded string
<?php
function rest_helper($url, $params = null, $verb = 'GET', $format = 'json')
{
$cparams = array(
'http' => array(
'method' => $verb,
'ignore_errors' => true
)
);
if ($params !== null) {
$params = http_build_query($params);
if ($verb == 'POST') {
$cparams['http']['content'] = $params;
} else {
$url .= '?' . $params;
}
}
$context = stream_context_create($cparams);
$fp = fopen($url, 'rb', false, $context);
if (!$fp) {
$res = false;
} else {
// If you're trying to troubleshoot problems, try uncommenting the
// next two lines; it will show you the HTTP response headers across
// all the redirects:
// $meta = stream_get_meta_data($fp);
// var_dump($meta['wrapper_data']);
$res = stream_get_contents($fp);
}
if ($res === false) {
throw new Exception("$verb $url failed: $php_errormsg");
}
switch ($format) {
case 'json':
$r = json_decode($res);
if ($r === null) {
throw new Exception("failed to decode $res as json");
}
return $r;
case 'xml':
$r = simplexml_load_string($res);
if ($r === null) {
throw new Exception("failed to decode $res as xml");
}
return $r;
}
return $res;
}
I need to be able to:
Add a content type of application/json
Convert params to JSON
Can't use curl in this environment
The main thing is the content type -- currently defaults to urlencoded
Any tips or ideas appreciated - Thanks
Latest attempt
function restHelper($url, $params = null, $verb = 'GET', $format = 'json'){
$cparams = array(
'http' => array(
'method' => $verb,
'ignore_errors' => true,
'header' =>"Content-type: application/json \r\n"
)
);
if ($params !== 'None') {
$jparams = json_encode($params);
if ($verb == 'POST') {
$cparams['http']['content'] = $jparams;
} elseif ($verb =='PUT') {
$cparams['http']['content'] = $jparams;
} else {
$params = http_build_query($params);
$url .= '?' . $params;
}
}
Still not working -- API tests fine from REST IDE Seems to be from how the content type is working for JSON

In the end found a way of including CURL in scriptcase.
Here is what worked (prototype)
(Thanks Lorna Jane http://www.lornajane.net/posts/2011/posting-json-data-with-php-curl)
Thanks everyone that looked at this
$service_url = 'http://dev.eventplus.co.nz/api/logon';
$ch = curl_init($service_url);
$data = '[
{
"Header": {
"Username": "testapi#teamprema.co.nz",
"SessionId": "123"
}
},
{
"Config": {}
},
{
"Params": {"Query": {"Password": "test12345"}}
}
]';
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data))
);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
$response = curl_exec($ch);
if ($response === false) {
$info = curl_getinfo($ch);
curl_close($ch);
die('error occured during curl exec. Additioanl info: ' . var_export($info));
}
curl_close($ch);
print $response;
