protected function https_request ($ url, $ data = null) {
     $ curl = curl_init ();
     curl_setopt ($ curl, CURLOPT_URL, $ url);
     curl_setopt ($ curl, CURLOPT_SSL_VERIFYPEER, FALSE);
     curl_setopt ($ curl, CURLOPT_SSL_VERIFYHOST, FALSE);
     if (! empty ($ data)) {
         curl_setopt ($ curl, CURLOPT_POST, 1);
         curl_setopt ($ curl, CURLOPT_POSTFIELDS, $ data);
     }
     curl_setopt ($ curl, CURLOPT_RETURNTRANSFER, 1);
     // The following line is the modified code, which is to configure the host access and send the data type as application / json
     curl_setopt ($ curl, CURLOPT_HTTPHEADER, array (
         'Content-Type: application / json; charset = utf-8',
         'Content-Length:'. Strlen ($ data)
     ));
     $ output = curl_exec ($ curl);
     curl_close ($ curl);
     return $ output;
}

2, send JSON format data, request address: HTTP

protected function curlPost ($ Url, $ data) {
     $ ch = curl_init ($ Url);
     curl_setopt ($ ch, CURLOPT_CUSTOMREQUEST, "POST");
     curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data); // $ data JSON type string
     curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true);
     curl_setopt ($ ch, CURLOPT_HTTPHEADER, array ('Content-Type: application / json', 'Content-Length:'. strlen ($ data)));
     $ result = curl_exec ($ ch);
     curl_close ($ ch);
     return $ result;
}

3. Submit Form form format

function file_get_contents_post($url, $post){
    $options = array(
        'http'=> array(
        'method'=>'POST',
        'header' => "Content-type: application/x-www-form-urlencoded ",
        'content'=> http_build_query($post),
        ),
    );
    $result = file_get_contents($url,false, stream_context_create($options));
    return $result;
}
$datare = file_get_contents_post("http://103.72.165.183/api/payment.aspx", $data);
var_dump($datare);

4, $url is the form of address plus data: http://baidu.com?a= "ss" &b= "DS";

public function getSSLHttp ($ url) {
         $ curl = curl_init ();
         curl_setopt ($ curl, CURLOPT_URL, $ url);
         curl_setopt ($ curl, CURLOPT_HEADER, false);
         curl_setopt ($ curl, CURLOPT_RETURNTRANSFER, true);
         curl_setopt ($ curl, CURLOPT_SSL_VERIFYPEER, FALSE); // https request does not verify certificates and hosts
         curl_setopt ($ curl, CURLOPT_SSL_VERIFYHOST, FALSE);
         $ data = curl_exec ($ curl);
         $ httpCode = curl_getinfo ($ curl, CURLINFO_HTTP_CODE);
         if ($ httpCode! = 200) {
             $ data = "https connect timeout";
         }
         curl_close ($ curl);
         return $ data;
     }
