Server response OK (200) but no file uploaded to server

Question

I am trying to upload a text file generated in a app to a server. When trying to get the server response I get a exception EOF thrown.

Any input appreciated

My create file code:

File sdCard = android.os.Environment.getExternalStorageDirectory();
            File theDirectory = new File(sdCard.getAbsolutePath());
            theFile = new File(theDirectory, "userdetails.txt");
            theDirectory.getParentFile().mkdirs();

            //file.createNewFile();
            FileOutputStream fOut = new FileOutputStream(theFile);
            OutputStreamWriter out = new OutputStreamWriter(fOut);
            out.append(username+"\n");
            out.append(email+"\n");
            out.append(password+"\n");
            out.close();

... uploadFileName = theFile.toString(); uploadFile( uploadFileName);

Upload Method:

String fileName = sourceFileUri;

          HttpURLConnection conn = null;
          DataOutputStream dos = null;  
          String lineEnd = "\r\n";
          String twoHyphens = "--";
          String boundary = "*****";
          int bytesRead, bytesAvailable, bufferSize;
          byte[] buffer;
          int maxBufferSize = 1 * 1024 * 1024; 
          File sourceFile = new File(sourceFileUri); 

          if (!sourceFile.isFile()) {

               dialog.dismiss(); 

               Log.e("uploadFile", "Source File not exist :" + uploadFileName);

               runOnUiThread(new Runnable() {
                   public void run() {
                       Log.d("REGISTRATION PAGE", "Source File not exist :" + uploadFileName);
                   }
               }); 

               return 0;

          }
          else
          {
               try { 

                     // open a URL connection to the Servlet
                   FileInputStream fileInputStream = new FileInputStream(sourceFile);
                   URL url = new URL(upLoadServerUri);

                   // Open a HTTP  connection to  the URL
                   conn = (HttpURLConnection) url.openConnection(); 
                   conn.setDoInput(true); // Allow Inputs
                   conn.setDoOutput(true); // Allow Outputs
                   conn.setUseCaches(false); // Don't use a Cached Copy
                   conn.setRequestMethod("POST");
                   conn.setRequestProperty("Connection", "close");
                   conn.setRequestProperty("ENCTYPE", "multipart/form-data");
                   conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
                   conn.setRequestProperty("uploaded_file", fileName); 

                   dos = new DataOutputStream(conn.getOutputStream());

                   dos.writeBytes(twoHyphens + boundary + lineEnd); 
                   dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename="
                                             + fileName + "" + lineEnd);

                   dos.writeBytes(lineEnd);

                   // create a buffer of  maximum size
                   bytesAvailable = fileInputStream.available(); 

                   bufferSize = Math.min(bytesAvailable, maxBufferSize);
                   buffer = new byte[bufferSize];

                   // read file and write it into form...
                   bytesRead = fileInputStream.read(buffer, 0, bufferSize);  

                   while (bytesRead > 0) {

                     dos.write(buffer, 0, bufferSize);
                     bytesAvailable = fileInputStream.available();
                     bufferSize = Math.min(bytesAvailable, maxBufferSize);
                     bytesRead = fileInputStream.read(buffer, 0, bufferSize);   

                    }



                   // send multipart form data necesssary after file data...
                   dos.writeBytes(lineEnd);
                   dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

                   // Responses from the server (code and message)
                   serverResponseCode = conn.getResponseCode();
                   String serverResponseMessage = conn.getResponseMessage();

                   Log.d("uploadFile", "HTTP Response is : "
                           + serverResponseMessage + ": " + serverResponseCode);

                   if(serverResponseCode == 200){

                       runOnUiThread(new Runnable() {
                            public void run() {

                                String msg = "File Upload Completed.\n\n See uploaded file here : \n\n"

                  runOnUiThread(new Runnable() {

                         // messageText.setText("MalformedURLException Exception : check script url.");
                          Toast.makeText(RegisterActivity.this, "MalformedURLException",

                  e.printStackTrace();

                  runOnUiThread(new Runnable() {
                      public void run() {
                         // messageText.setText("Got Exception : see logcat ");
                          Toast.makeText(RegisterActivity.this, "Got Exception : see logcat ", 
                                  Toast.LENGTH_SHORT).show();

                  Log.e("Upload file to server Exception", "Exception : "

              }
              dialog.dismiss();       
              return serverResponseCode; 

And my php script on server:

<?php

    $file_path = "uploads/";

    $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
        echo "success";
    } else{
        echo "fail";
    }
 ?>

UPDATE: Changed the DataOutPutStrem args here(I had a \\ in the world place):

 dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\"" + fileName + "\"" + lineEnd);

This gives a server

response = OK and respoonseCode = 200;

However I see no new file in the server directory! Ive Logged the directory where the new file should be as the URL+filePath which is

www.mooneycallans/Rotunda//storage/emulated/0/userdetails.txt

But should this not read:

www.mooneycallans/Rotunda/userdetails.txt

... as userdetails.txt is the name of the file I have created in the app.

Answer 1

Ouch. My php scrip was the culprit, I had the path as :

$file_path = "uploads";

Instaed of:

$file_path = "uploads/";

A day and a half later but it works :)
