Post request with file_get_content not working - php

Question

I am trying to use file_get_contents to "post" to a url and get auth token. The problem I am having is that it returns a error.
Message: file_get_contents(something): failed to open stream: HTTP request failed! HTTP/1.1 411 Length Required.
I am not sure what is causing this but need help. Here is the function.
public function ForToken(){
$username = 'gettoken';
$password = 'something';
$url = 'https://something.com';
$context = stream_context_create(array (
'http' => array (
'header' => 'Authorization: Basic ' . base64_encode("$username:$password"),
'method' => 'POST'
)
));
$token = file_get_contents($url, false, $context);
if(token){
var_dump($token);
}else{
return $resultArray['result'] = 'getting token failed';
}
}
I tried it with POSTMAN, and it works, so only problem I am having is that why isnt it working with file_get_contents.

Answer 1

Cannot command so i will do it this way. If you use Postman why don't you let Postman generate the code for you. In postman you can click code at a request and you can even select in what coding language you wanne have it. Like PHP with cURL:
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "http://somthing.com/",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_HTTPHEADER => array(
"password: somthing",
"username: gettoken"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
Hope this will help!

I can not comment because of my reputation;
In some servers file_get_content is not available...
You may try with CURL like this

Answer 3

Your request havent any data and content length is missing.
You can try this:
public function ForToken(){
$username = 'gettoken';
$password = 'something';
$url = 'https://something.com';
$data = array('foo' => 'some data');
$data = http_build_query($data);
$context_options = array (
'http' => array (
'method' => 'POST',
'header'=> "Content-type: application/x-www-form-urlencoded\r\n"
. "Authorization: Basic " . base64_encode("$username:$password") . "\r\n"
. "Content-Length: " . strlen($data) . "\r\n",
'content' => $data
)
);
$context = context_create_stream($context_options);
$token = file_get_contents($url, false, $context);
if(token){
var_dump($token);
}else{
return $resultArray['result'] = 'getting token failed';
}
}

RFC2616 10.4.12
https://www.rfc-editor.org/rfc/rfc2616#section-10.4.12
Code: (Doesn't work, see below)
public function ForToken(){
$username = 'gettoken';
$password = 'something';
$url = 'https://something.com';
$context = stream_context_create(array (
'http' => array (
'header' => 'Authorization: Basic ' . base64_encode("$username:$password") . 'Content-Length: ' . strlen($url) . '\r\n',
'method' => 'POST'
)
));
$token = file_get_contents($url, false, $context);
if(token){
var_dump($token);
}else{
return $resultArray['result'] = 'getting token failed';
}
}
2nd Try:
public function ForToken(){
$username = 'gettoken';
$password = 'something';
$url = 'https://something.com';
$context_options = array (
'http' => array (
'method' => 'POST',
'header'=> "Content-type: application/x-www-form-urlencoded\r\n" . "Authorization: Basic " . base64_encode("$username:$password") . "Content-Length: " . strlen($url) . "\r\n",
'content' => $url
)
);
$context = stream_context_create($context_options);
$token = file_get_contents($url, false, $context);
if(token){
var_dump($token);
}else{
return $resultArray['result'] = 'getting token failed';
}
}
