服務器響應正常（200），但沒有文件上傳到服務器

Question

我正在嘗試將應用程序中生成的文本文件上傳到服務器。 嘗試獲取服務器響應時，我拋出了異常EOF。

任何輸入表示贊賞

我的創建文件代碼：

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）;

上載方法：

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"
                                              +" http://www.androidexample.com/media/uploads/"
                                              +uploadFileName;

                                //messageText.setText(msg);
                                Toast.makeText(RegisterActivity.this, "File Upload Complete.",  Toast.LENGTH_SHORT).show();
                            }
                        });                
                   }    

                   //close the streams //
                   fileInputStream.close();
                   dos.flush();
                   dos.close();

              } catch (MalformedURLException ex) {

                  dialog.dismiss();  
                  ex.printStackTrace();

                  runOnUiThread(new Runnable() {
                      public void run() {
                         // messageText.setText("MalformedURLException Exception : check script url.");
                          Toast.makeText(RegisterActivity.this, "MalformedURLException", 
                                                              Toast.LENGTH_SHORT).show();
                      }
                  });

                  Log.e("Upload file to server", "error: " + ex.getMessage(), ex);  
              } catch (Exception e) {

                  dialog.dismiss();  
                  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 : "
                                                   + e.getMessage(), e);  
              }
              dialog.dismiss();       
              return serverResponseCode; 

和我的服務器上的PHP腳本：

<?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";
    }
 ?>

更新：在這里更改了DataOutPutStrem參數（我在世界上有一個\\）：

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

這給服務器

response = OK and respoonseCode = 200;

但是，我在服務器目錄中看不到任何新文件！ 我已經記錄了新文件應該作為URL + filePath的目錄

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

但這不應該讀為：

www.mooneycallans / Rotunda / userdetails.txt

... as userdetails.txt是我在應用程序中創建的文件的名稱。

哎喲。 我的php scrip是罪魁禍首，我的路徑為：

$file_path = "uploads";

裝備：

$file_path = "uploads/";

一天半后，它仍然有效:)
