Android - 从应用程序上传图像到IIS服务器

Question

我一直在Android开发应用程序一段时间，现在我需要从这个应用程序上传图像到服务器。事情是，我真的不知道如何在后端（这是服务器端）做到这一点。我读过很多关于通过httpmime库和使用multipart发送图像，但没有太多关于接收图像的服务器端服务。

我需要使用像MVC3或WCF的东西，因为我们在这里的服务器是IIS，我还没有找到很多关于如何使用此模型来做到这一点。因此，任何有关如何使用此模型实现该功能的教程或指南都是我所需要的，任何帮助也都将得到真正的赞赏。

public String sendFilePost(String urlServer, String pathToOurFile){ 
        HttpURLConnection connection = null; 
        DataOutputStream outputStream = null; 
        DataInputStream inputStream = null; 
        String lineEnd = "\r\n"; 
        String twoHyphens = "--"; 
        String boundary = "*****"; 
        int bytesRead, bytesAvailable, bufferSize; 
        byte[] buffer; 
        int maxBufferSize = 1*1024*1024; 
        try 
        { 
        FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile)); 
        URL url = new URL(urlServer); 
        connection = (HttpURLConnection) url.openConnection(); 
        connection.setDoInput(true); 
        connection.setDoOutput(true); 
        connection.setUseCaches(false); 
        connection.setRequestMethod("POST"); 
        connection.setRequestProperty("Connection", "Keep-Alive"); 
        connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary); 

        outputStream = new DataOutputStream(connection.getOutputStream()); 
        outputStream.writeBytes(twoHyphens + boundary + lineEnd); 
        outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile +"\"" + lineEnd); 
        outputStream.writeBytes(lineEnd); 

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

        // Read file 
        bytesRead = fileInputStream.read(buffer, 0, bufferSize); 

        while (bytesRead > 0) 
        { 
        outputStream.write(buffer, 0, bufferSize); 
        bytesAvailable = fileInputStream.available(); 
        bufferSize = Math.min(bytesAvailable, maxBufferSize); 
        bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
        } 

        outputStream.writeBytes(lineEnd); 
        outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 

        // Responses from the server (code and message) 
        String serverResponseMessage = connection.getResponseMessage(); 
        InputStream is = connection.getInputStream(); 
        BufferedReader rd = new BufferedReader(new InputStreamReader(is)); 
        String line; 
        StringBuffer response = new StringBuffer(); 
        while((line = rd.readLine()) != null) { 
         response.append(line); 
        } 
        String rrrr = response.toString(); 
        rd.close(); 
        fileInputStream.close(); 
        outputStream.flush(); 
        outputStream.close(); 
        return rrrr; 
        } 
        catch (Exception ex) 
        { 
         return "Something went wrong!"; 
        } 
       }
