cURL不再工作，给出408错误

Question

I have a cURL code which was working before but recently it stopped working and gives a 408 request timeout error. I want to know the reason why it stopped working and how can I fix it. Here's the code :

$curlSession = curl_init();
curl_setopt($curlSession, CURLOPT_HTTPHEADER, $header);
curl_setopt($curlSession, CURLOPT_URL, $actualUrl); 
curl_setopt($curlSession, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($curlSession, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curlSession, CURLOPT_POST, 0);
curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curlSession, CURLOPT_TIMEOUT,1100);
curl_setopt($curlSession, CURLOPT_SSLCERT, $clientcert); 
curl_setopt($curlSession, CURLOPT_SSLCERTTYPE, 'PEM'); 
curl_setopt($curlSession, CURLOPT_SSLKEYTYPE, 'PEM'); 
curl_setopt($curlSession, CURLOPT_SSLKEY, $keyfile); 
curl_setopt($curlSession, CURLOPT_CONNECTTIMEOUT, 0);
curl_setopt($curlSession, CURLOPT_USERAGENT, $agent);
$data = curl_exec($curlSession);

I tried it with the Postman application and it still works on Postman without any delay.Is there any alternative to cURL that I can use to check this?

The 408 Request Timeout error is an HTTP status code that means the request you sent to the website server (e.g. a request to load a web page) took longer than the website's server was prepared to wait. In other words, your connection with the website "timed out."

You can test your API with postman first to see whether it is working fine.

Is your api return large amount of data or your remote server is slow resulting a long request-response time?

See documentation: http://www.php.net/manual/en/function.curl-setopt.php

CURLOPT_CONNECTTIMEOUT - The number of seconds to wait while trying to connect. Use 0 to wait indefinitely. URLOPT_TIMEOUT - The maximum number of seconds to allow cURL functions to execute.

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0); 
curl_setopt($ch, CURLOPT_TIMEOUT, 400); //timeout in seconds

also don't forget to enlarge time execution of php script if needed.

set_time_limit(0);
