2. Request and debugging
There is a very convenient curl in php, here is CURLOPT_SSL_VERIFYPEER. This attribute was not added at the beginning, and the data returned every time when requesting the WeChat server is false. Later, I used firefox's HttpRequester to simulate the request. I can return to the data. After searching for the information, I found that I want to set this property.
CURLOPT_SSL_VERIFYPEER: Whether to detect whether the server's certificate is issued by an authorized CA certified by a regular browser
/**
* Original POST
* @param $url The url address requested
* @param $raw raw data, can be a string or an array
* @return mixed Return the request value
*/
public function rawpost($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('Expect:'));
$data = curl_exec($resource);
curl_close($resource);
return $data;
}
Here we recommend HttpRequester, this plugin can simulate various submissions such as post and get, and you can also choose from content type.
