How to add Content-length To http request in php - php

Question

I want to use octoparse API.
AND I have error when I want to clear data in octoparse API.
AND this my code
ini_set('max_execution_time', 300);
$url = 'https://dataapi.octoparse.com/api/task/RemoveDataByTaskId?taskId=<mytaskid>';
$options = array(
'http' => array(
'header' => "Authorization: bearer <mykey>",
'method' => 'POST'
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) {
echo 'error';
}
var_dump($result);
My result
Warning: file_get_contents(https://dataapi.octoparse.com/api/task/RemoveDataByTaskId?taskId=<mytaskid>): failed to open stream: HTTP request failed! HTTP/1.1 411 Length Required
And I try to add Content-length But It have an error My new code:
ini_set('max_execution_time', 300);
$url = 'https://dataapi.octoparse.com/api/task/RemoveDataByTaskId?taskId=<mytaskid>';
$a=strlen($url);
$options = array(
'http' => array(
'header' => "Authorization: bearer <my key>",
'method' => 'POST',
'header' => sprintf('Content-Length: %d', $a)
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) {
echo 'error';
}
var_dump($result);
My result
Warning: file_get_contents(https://dataapi.octoparse.com/api/task/RemoveDataByTaskId?taskId=<mytaskid>): failed to open stream: HTTP request failed!
Can anyone know how to solve my problem.

Answer 1

you are using multiple headers in HTTP. if you are using multiple headers then follow this process
'header' => array(
"Authorization: bearer <my key>",
sprintf('Content-Length: %d', $a)
),
And you can also used this code
$requestHeaders = array(
'Content-type: application/x-www-form-urlencoded',
'Authorization: bearer <my key>',
sprintf('Content-Length: %d', strlen($url));
);
$options = array(
'http' => array(
'method' => 'POST',
'header' => implode("\r\n", $requestHeaders),
)
);
