This article describes how PHP uses curl to simulate post Upload and file receipt. it involves some techniques related to PHP's use of curl for post file transmission, for more information about how PHP uses curl to simulate post Upload and file receipt, see the following example. We will share this with you for your reference. The details are as follows:
Public function Action_Upload () {$ this-> path_config (); exit (); $ furl = "@ d: \ develop \ JMFrameworkWithDemo.rar"; $ url =" http://localhost/DemoIndex/curl_pos/ "; $ This-> upload_file_to_cdn ($ furl, $ url);} public function upload_file_to_cdn ($ furl, $ url) {// initialize $ ch = curl_init (); // address of the local file to be uploaded "@ F:/xampp/php. ini "before the upload path, you must have the @ symbol $ post_data = array (" upload "=> $ furl); // print_r ($ post_data ); // CURLOPT_URL indicates where to submit it? Equivalent to the path specified by "action" in the form // $ url =" http://localhost/DemoIndex/curl_pos/ "; // Set the variable curl_setopt ($ ch, CURLOPT_URL, $ url); curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 0); // whether the execution result is returned, 0 is returned, 1 is not returned curl_setopt ($ ch, CURLOPT_HEADER, 0); // parameter settings, whether to display the header information, 1 is displayed, 0 is not displayed // forge the webpage source address, forge a form from Baidu and submit curl_setopt ($ ch, CURLOPT_REFERER ," http://www.baidu.com "); // Form data, which is a regular form setting value that is not 0 curl_setopt ($ ch, CURLOPT_POST, 1); curl_setopt ($ ch, CURLOPT_TIMEOUT, 100 ); // set the maximum timeout value for curl execution. // when the array is used to provide post data, the CURL component is probably used to be compatible with the file uploading method such as @ filename, // content_type is set to multipart/form-data by default. Although it does not affect most web servers, a small number of servers are not compatible. The conclusion in this article is that, without the need to upload a file //, we try to perform http_build_query on the data submitted by post and then send it out to achieve better compatibility, smaller request packets. Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ post_data); // execute and obtain the result curl_exec ($ ch); if (curl_exec ($ ch) === FALSE) {echo"
"," CUrl Error :". curl_error ($ ch) ;}// release cURL handle curl_close ($ ch); echo "aaa45" ;}function action_curl_pos () {var_dump ($ _ FILES ); $ aa = move_uploaded_file ($ _ FILES ["upload"] ["tmp_name"], "/wamp/tools/1.rar"); if ($ aa) {echo "11 ";}}
