有没有人做到了这一点before.If是的，他可以帮我

我创建一个类我需要发送的所有信息并使用简单的XML将其序列化为xml文件。然后我发送整个XML。 但你也可以只发送字段：

static String CRLF = "\r\n"; 
static String twoHyphens = "--"; 
static String boundary = "*****mgd*****"; 
private DataOutputStream dataStream = null; 

private void postData(){ 
    try{ 
      URL connectURL = new URL("http://example.com/upload.php"); 
      HttpURLConnection conn = (HttpURLConnection)connectURL.openConnection(); 
      conn.setDoInput(true); 
      conn.setDoOutput(true); 
      conn.setUseCaches(false); 
      conn.setRequestMethod("POST"); 
      conn.setRequestProperty("User-Agent", "test"); 
      conn.setRequestProperty("Connection","Keep-Alive"); 
      conn.setRequestProperty("Content-Type","multipart/form-data;boundary="+boundary); 
      conn.connect(); 

      dataStream = new DataOutputStream(conn.getOutputStream()); 
       //Send fields 
      writeFormField("name", "bla"); 
       writeFormField("password", "bla"); 
       //Send a file 
     File uploadFile = new File(SD_CARD_TEMP_DIR, "file.xml"); 
      FileInputStream fileInputStream = new FileInputStream(uploadFile); 
      writeFileField("myFile", "somefilename.xml", "text/xml",fileInputStream); 

      // final closing boundary line 
      dataStream.writeBytes(twoHyphens + boundary +twoHyphens + CRLF); 
      fileInputStream.close(); 
      dataStream.flush(); 
      dataStream.close(); 
      dataStream = null; 

      boolean response = getResponse(conn); 
      if(response) 
      { 
       finish(); 
      } 

     } 
     catch (MalformedURLException mue) { 
      // TODO 
     } 
     catch (IOException ioe) { 
      // TODO 
     } 
     catch (Exception e) { 
      // TODO 
     } 
} 
private void writeFormField(String fieldName, String fieldValue) { 
    try { 
     dataStream.writeBytes(twoHyphens + boundary + CRLF); 
     dataStream.writeBytes("Content-Disposition: form-data;name=\"" + fieldName + "\"" + CRLF); 
     dataStream.writeBytes(CRLF); 
     dataStream.writeBytes(fieldValue); 
     dataStream.writeBytes(CRLF); 
    } catch (Exception e) { 
     System.out.println("writeFormField:got: " + e.getMessage()); 

    } 
} 

private void writeFileField(
     String fieldName, 
     String fieldValue, 
     String type, 
     FileInputStream fis) 
    { 
     try 
     { 
      // opening boundary line 
      dataStream.writeBytes(twoHyphens + boundary + CRLF); 
      dataStream.writeBytes("Content-Disposition: form-data; name=\"" 
            + fieldName 
            + "\";filename=\"" 
            + fieldValue 
            + "\"" 
            + CRLF); 
      dataStream.writeBytes("Content-Type: " + type + CRLF); 
      dataStream.writeBytes(CRLF); 

      // create a buffer of maximum size 
      int bytesAvailable = fis.available(); 
      int maxBufferSize = 1024; 
      int bufferSize = Math.min(bytesAvailable, maxBufferSize); 
      byte[] buffer = new byte[bufferSize]; 
      // read file and write it into form... 
      int bytesRead = fis.read(buffer, 0, bufferSize); 
      while (bytesRead > 0) 
      { 
       dataStream.write(buffer, 0, bufferSize); 
       bytesAvailable = fis.available(); 
       bufferSize = Math.min(bytesAvailable, maxBufferSize); 
       bytesRead = fis.read(buffer, 0, bufferSize); 
      } 

      // closing CRLF 
      dataStream.writeBytes(CRLF); 
     } 
     catch(Exception e) 
     { 
      Log.i(TAG, "writeFormField: got: " + e.getMessage()); 
     } 
    } 
private boolean getResponse(HttpURLConnection conn) 
{ 
    try { 
     // try doing this in one read 
     InputStream data = conn.getInputStream(); 
     StringBuffer sb = new StringBuffer(); 
     //Reader reader = new InputStreamReader(data, "UTF-8"); 
     int c; 
     while ((c = data.read()) != -1) sb.append((char) c); 
     String document = sb.toString(); 
     int responseCode = conn.getResponseCode(); 
     return true; 
    } 
    catch(Exception e) 
    { 

    } 
    return false;
