上傳圖片HTTP POST Android

Question

我是android新手，並有問題上傳android中的圖像。我已經試圖找到例子，但有沒有運氣：

我有錯誤說：

這裏是我的代碼： 我有一個名爲"images"數組，它包含我想要上傳的圖像的路徑 例如/storage/sdcard0/DCIM/Camera/IMG_20131214_171438.jpg

//ONCLICK LISTENER  
public OnClickListener upload_image = new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       if(images.size() != 0) { 

        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
        StrictMode.setThreadPolicy(policy); 

        for(int i=0; i<images.size(); i++){ 
         doFileUpload(images.get(i)); 
        } 
       } 
      } 
     }; 

// UPLOAD

private void doFileUpload(String upload_file){ 
       Log.d("Currently queued", upload_file); 
       HttpURLConnection conn = null; 
       DataOutputStream dos = null; 
       DataInputStream inStream = null; 
       String exsistingFileName = upload_file; 
       // Is this the place are you doing something wrong. 
       String lineEnd = "\r\n"; 
       String twoHyphens = "--"; 
       String boundary = "acebdf13572468"; 
       int bytesRead, bytesAvailable, bufferSize; 
       byte[] buffer; 
       int maxBufferSize = 1*1024*1024; 
       String urlString = "http://test.xponlm.com/MobileServices/api/ShipmentImages"; 
       try 
       { 
        Log.e("MediaPlayer","Inside second Method"); 
        FileInputStream fileInputStream = new FileInputStream(new File(exsistingFileName)); 
        URL url = new URL(urlString); 
        conn = (HttpURLConnection) url.openConnection(); 
        conn.setDoInput(true); 
        // Allow Outputs 
        conn.setDoOutput(true); 
        // Don't use a cached copy. 
        conn.setUseCaches(false); 
        // Use a post method. 
        conn.setRequestMethod("POST"); 
        conn.setRequestProperty("Connection", "Keep-Alive"); 
        conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary); 
        dos = new DataOutputStream(conn.getOutputStream()); 
        dos.writeBytes(twoHyphens + boundary + lineEnd); 
        dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + exsistingFileName +"\"" + lineEnd); 
        dos.writeBytes(lineEnd); 

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

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

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

        Log.e("MediaPlayer","Headers are written"); 
        bytesAvailable = fileInputStream.available(); 
        bufferSize = Math.min(bytesAvailable, maxBufferSize); 
        buffer = new byte[bufferSize]; 
        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); 
        } 

        dos.writeBytes(lineEnd); 
        dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 
        BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream())); 
        String inputLine; 
        while ((inputLine = in.readLine()) != null) 
//      tv.append(inputLine); 
         Log.d("inputLine", inputLine); 
        // close streams 
        Log.e("MediaPlayer","File is written"); 
        fileInputStream.close(); 
        dos.flush(); 
        dos.close(); 
       } 
       catch (MalformedURLException ex) 
       { 
        Log.e("MediaPlayer", "error1: " + ex.getMessage(), ex); 
       } 
       catch (IOException ioe) 
       { 
        Log.e("MediaPlayer", "error2: " + ioe.getMessage(), ioe); 
       } 

       //------------------ read the SERVER RESPONSE 
       try { 
        inStream = new DataInputStream (conn.getInputStream()); 
        String str;    

        while ((str = inStream.readLine()) != null) { 
         Log.e("MediaPlayer","Server Response"+str); 
        } 
        /*while((str = inStream.readLine()) !=null){ 

        }*/ 
        inStream.close(); 
       } 
       catch (IOException ioex){ 
        Log.e("MediaPlayer", "error3: " + ioex.getMessage(), ioex); 
       } 
      } 

難道我錯過了財產以後？你能告訴我的代碼有什麼問題嗎？

Answer 1

public Fileupload(String url, String userid, 
      String filepath, String status) { 
     HttpClient httpclient = new DefaultHttpClient(); 
     HttpPost httppost = new HttpPost(url); 
     MultipartEntity entity = new MultipartEntity(
       HttpMultipartMode.BROWSER_COMPATIBLE); 
     HttpParams httpParams = httpclient.getParams(); 
     httpParams.setIntParameter(CoreConnectionPNames.SO_TIMEOUT, 100000); 
     try { 
      entity.addPart("key 1", 
        new StringBody(userid, Charset.forName("UTF-8"))); 
      entity.addPart("key 2", 
        new StringBody(status, Charset.forName("UTF-8"))); 
      entity.addPart("File ", new FileBody(new File(filepath))); 
      httppost.setEntity(entity); 
      ResponseHandler<String> responseHandler = new BasicResponseHandler(); 
      String response = httpclient.execute(httppost, responseHandler); 

     } catch (Exception e) { 

     } 
    }
