Ii. Request and debugging

Php has a very convenient curl. Here we mention CURLOPT_SSL_VERIFYPEER. If this attribute is not added at the beginning, the returned data is false each time the server is requested. After simulating the request with HttpRequester of firefox, you can return the data. After searching for the information, you will find that you want to set this attribute.

CURLOPT_SSL_VERIFYPEER: checks whether the server certificate is issued by an authorized CA authorized by a regular browser.
/**
* Original POST
* @ Param $ url the url of the request
* @ Param $ raw data, which can be a string or Array
* @ Return mixed return the request Value
*/
Public function rawpost ($ url, $ raw)
{
$ Resource = curl_init ();
Curl_setopt ($ resource, CURLOPT_POST, true );
Curl_setopt ($ resource, CURLOPT_URL, $ url );
Curl_setopt ($ resource, CURLOPT_POSTFIELDS, $ raw );
Curl_setopt ($ resource, CURLOPT_RETURNTRANSFER, true );
Curl_setopt ($ resource, CURLOPT_SSL_VERIFYHOST, false );
Curl_setopt ($ resource, CURLOPT_SSL_VERIFYPEER, false );
// Curl_setopt ($ resource, CURLOPT_HTTPHEADER, array ('ct :'));
$ Data = curl_exec ($ resource );
Curl_close ($ resource );
Return $ data;
}

HttpRequester is recommended here. This plug-in can simulate various submissions such as post and get, and content type can also be selected.

Development also provides an online test interface. Click to view the public platform interface debugging tool.
