Both programs post a file to a website. how can I use php to implement the file? please check the code. thank you!

To post a file to a website, you can use curl to submit the file in php. You can search for usage.

I tried it and reported a bunch of errors. I don't know anything about java. I didn't have any problems when I submitted the test to my php server, after the do file can be formally submitted to another java Server, an error is reported. it takes several days to get depressed and ask for help.

$uploadFile = file_get_contents($filePath);//content boundary $boundary   = md5(time());$postStr  = "";$postStr .="--".$boundary."\r\n";$postStr .="Content-Disposition: form-data; name=\"\"; filename=\"a.txt\"\r\n";$postStr .="Content-Type: text/plain\r\n\r\n";$postStr .=$uploadFile."\r\n";$postStr .="--".$boundary."\r\n";                                                                                                                                            /** use curl instead **/$cl = curl_init($url);$boundary = md5(time());curl_setopt($cl,CURLOPT_POST,true);curl_setopt($cl,CURLOPT_HTTPHEADER,array(        "Content-Type: multipart/form-data; boundary=".$boundary));curl_setopt($cl,CURLOPT_POSTFIELDS,$postStr);curl_setopt($cl,CURLOPT_RETURNTRANSFER,true);$content = curl_exec($cl);curl_close($cl);echo $content;
