cURL在发出SOAP请求时返回bool（false）

Question

I am trying to make a SOAP request using cURL but I am getting the following errors. For the output of the result, I get "bool(false)". For the curl_error() function, I get "Operation timed out after 30000 milliseconds with 0 bytes received".

My question is whether I am missing something that could be preventing the connection, possibly in the cURL options?

This is my code:

<?php
function soap_subscriber($subscriber_email) {

    $soap_endpoint = '[HIDDEN]';
    $soap_username = '[HIDDEN]';
    $soap_userpass = '[HIDDEN]';

    define('USERNAME', '[HIDDEN]');
    define('PASSWORD', '[HIDDEN]');
    define('ENDPOINT', $soap_endpoint);
    date_default_timezone_set('America/Nassau');

    $ch = '<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"

Answer 1

Your SOAP request requires more than 30 seconds to finish its execution. Some solutions you can try:

• Increase cURL operation time limit:

  curl_setopt($ch, CURLOPT_TIMEOUT, 400); // 400 seconds

• Set set_time_limit to 0 to make your requests run for infinite seconds:

  set_time_limit(0);

  but downside is that hanging or running out of memory is possible.

• Try adding this to your cURL options to prevent infinite redirection from the server:

  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);

Hope this helps!
