PHP simulates post request to send file code

Due to the needs of the project, the local server needs to receive the data and then forward the data to another server, so a simulated post request is used to send the data. Of course, the data also includes file streams.

curl is one of the more commonly used methods in PHP. The general code is as follows:

 $params1 = "test";
 $params2 = "@".$absolute_path;//If it is a file, the parameter is "@"+ Absolute path
 $post_data = array(
 'params1' => $params1,
 'params2' => $params2,
 );
 function postData($url, $data){
 $ch = curl_init();
 $timeout = 300;
 curl_setopt($ch, CURLOPT_URL, $url); //Request address
 //curl_setopt($ch, CURLOPT_REFERER, $ip);//Construction source
 curl_setopt($ch, CURLOPT_POST, true ; When CURLOPT_RETURNTRANSFER is set to 1, $head has the return value of the request
 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); //Set the request timeout
 $handles = curl_exec($ch);
 curl_close($ch);
 return $ handles;
 }


Copy code

curl_setopt( $ch, CURLOPT_HTTPHEADER, $header);
