Android端使用OKHTTP通过MultiPartBody提交数据,服务端该如何写？
|
//为一个按钮注册的click事件public void doPost(View v){ new Thread(){ @Override public void run() { L.e(picPath); File file=new File(picPath); MediaType mediaType= MediaType.parse("application/octet-stream"); RequestBody requestBody=RequestBody.create(mediaType,file); RequestBody multipartBody=new MultipartBody.Builder().setType(MultipartBody.FORM) .addFormDataPart("username",username) .addFormDataPart("password",password) .addFormDataPart("mIcon",username,requestBody) .build(); Request request=new Request.Builder().url(mBaseUrl+"getMessage").post(multipartBody).build(); execute(request); } }.start(); //execute方法private void execute(Request request) { Call call=okHttpClient.newCall(request); call.enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { L.e("onFailure :"+e.getMessage()); e.printStackTrace(); } @Override public void onResponse(Call call, Response response) throws IOException { L.e("onResponse :"); res=response.body().string(); L.e(res); runOnUiThread(new Runnable() { @Override public void run() { mTvResult.setText(res); } }); } });}//服务端@WebServlet("/getMessage")public class test extends HttpServlet { protected void doPost(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws javax.servlet.ServletException, IOException { String userName=request.getParameter("username"); String password=request.getParameter("password"); System.out.println(userName+" "+password); File mIcon=new File("E//test_img",userName); InputStream is= request.getInputStream(); FileOutputStream fos=new FileOutputStream(mIcon); int len; byte [] buf=new byte[3*1024]; while((len=is.read(buf))!=-1) { fos.write(buf,0,len); } fos.flush(); fos.close(); }这样接收到的userName和password都是空。恳请各位大牛指点一二。。。 |

你客户端发送username值，谁知道是不是空值呢？ |
