copied!<p>I've also been facing the same kind of problem a short time ago. After some researches, I found out that the HttpComponents library from Apache (<a href="http://hc.apache.org/" rel="nofollow">http://hc.apache.org/</a>) contains pretty much everything you'll need to build HTTP-POST request in a quite simple way.</p> <p>Here is a method that will send a POST request with a file to a certain URL:</p> <pre><code>public static void upload(URL url, File file) throws IOException, URISyntaxException { HttpClient client = new DefaultHttpClient(); //The client object which will do the upload HttpPost httpPost = new HttpPost(url.toURI()); //The POST request to send FileBody fileB = new FileBody(file); MultipartEntity request = new MultipartEntity(); //The HTTP entity which will holds the different body parts, here the file request.addPart("file", fileB); httpPost.setEntity(request); HttpResponse response = client.execute(httpPost); //Once the upload is complete (successful or not), the client will return a response given by the server if(response.getStatusLine().getStatusCode()==200) { //If the code contained in this response equals 200, then the upload is successful (and ready to be processed by the php code) System.out.println("Upload successful !"); } } </code></pre> <p>In order to complete the upload, you must have a php code that handle that POST request, here it is:</p> <pre><code><?php $directory = 'Set here the directory you want the file to be uploaded to'; $filename = basename($_FILES['file']['name']); if(strrchr($_FILES['file']['name'], '.')=='.png') {//Check if the actual file extension is PNG, otherwise this could lead to a big security breach if(move_uploaded_file($_FILES['file']['tmp_name'], $directory. $filename)) { //The file is transfered from its temp directory to the directory we want, and the function returns TRUE if successfull //Do what you want, SQL insert, logs, etc } } ?> </code></pre> <p>The URL object given to the Java method must point to the php code, like <a href="http://mysite.com/upload.php" rel="nofollow">http://mysite.com/upload.php</a> and can be build very simply from a String. The file can also be build from a String representing its path. </p> <p>I didn't take the time to test it properly, but it was build upon proper working solution, so I hope this will help you.</p>
