How to upload php http files?

PHP uses CURL (HTTP) to upload files to another server.

The code is as follows:

/ / upload / * push the xls file * @ Date 2019-4-29 * / public function putXls () {/ / destination interface $url = "http://xxx"; / / initialize the cURL session. If the url,CURLOPT_URL option is provided, it will be set to the value $ch = curl_init ($url). / / get CURLFile instance $xlsCurlFile = $this- > makeCurlFile (base_path (). "/ public/tby.xls"); $data = array ('xls' = > $xlsCurlFile); / / TRUE sends a POST request of type: application/x-www-form-urlencoded, which is the most common one when HTML forms are submitted. Curl_setopt ($ch, CURLOPT_POST, 1); / / since PHP 5.5.0, the @ prefix has been deprecated and files can be sent via CURLFile. Setting CURLOPT_SAFE_UPLOAD to TRUE disables sending files with the @ prefix to increase security. Curl_setopt ($ch, CURLOPT_POSTFIELDS, $data); / / returns TRUE on success of the given cURL session / / or returns FALSE on failure. However, if the CURLOPT_RETURNTRANSFER option is set, the function returns the result of execution on success and FALSE on failure. $result = curl_exec ($ch); if (curl_errno ($ch)) {/ / returns an error code or 0 (zero) if no error occurs. / / returns an error message, or returns''(empty string) if no error occurs. $result = curl_error ($ch);} / / close cURL session curl_close ($ch) } / * get an instance of CURLFile class * @ param string $file file path * @ return CURLFile * @ Date 2019-4-29 * / private function makeCurlFile (string $file) {/ * * .xls mime is application/vnd.ms-excel * .xl sx mime is application/vnd.openxmlformats-officedocument. Spreadsheetml.sheet * refer to https://developer.mozilla.org/zh-CN/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Complete_list_of_MIME_types * * Note: you can also use the finfo class to get dynamic data. But you need to install the fileinfo extension * demo: $result = new finfo () If (is_resource ($result) = true) {return $result- > file ($filename, FILEINFO_MIME_TYPE);} return false; * / $mime = "application/vnd.ms-excel"; $info = pathinfo ($file); $name = $info ['basename']; $output = new CURLFile ($file, $mime, $name); return $output } / / the folder saved by the receiver public function getFile () {/ / needs to pay attention to whether the user group has write permission $uploads_dir = base_path (). "/ public/test"; $xlsFiles = $_ FILES ["xls"]? Null; if ($xlsFiles) {if ($xlsFiles ["error"] = = UPLOAD_ERR_OK) {$tmp_name = $xlsFiles ["tmp_name"]; $name = $xlsFiles ["name"]; move_uploaded_file ($tmp_name, "$uploads_dir/$name") } / / todo success} else {/ / todo fail}} "how php implements the function of uploading http files" ends here.
