【NanoHTTPD】Android，使用NanoHTTPD搭建服务器，接受Http请求，最佳实践安卓app，作为服务器，接受Http，get post 请求推送数据，NanoHTTPD是一个免费、轻量级的(只有一个Java文件) HTTP服务器,可以很好地嵌入到Java程序中。支持 GET, POST, PUT, HEAD 和 DELETE 请求，支持文件上传，占用内存很小。阅读详情

如题，最近在学Android发布http，遇到问题了，服务端可以监听到连接，可是在解析数据的时候它一直在阻塞，有谁知道嘛？
上代码：

服务端：



@Override

	public Response serve(IHTTPSession session) {

		// TODO Auto-generated method stub

		super.serve(session);

		try {

			System.out.println(session.getUri());

			System.out.println("XXXXXXXXXXXXXXXXXXXXXXXXXXX");

			String body = parseBody(session);//在这里阻塞了

			System.out.println(body);

			JSONObject request = new JSONObject(body);

			//String action = request.getString("action");

			JSONObject o = new JSONObject();

			o.put("result", "gfdgf");

			String resp = o.toString();

			Response response = new Response(Response.Status.OK,"application/json",resp);

			System.out.println("result:"+resp);

			return response;

		} catch(JSONException e) {

			e.printStackTrace();

			return null;

		}

	}

	

	private String parseBody(IHTTPSession session) {

		

		String body = null;

		try {

			InputStream is = session.getInputStream();

			if (is == null) {

				//Log.i(TAG, "session.getInputStream() is null!");

				System.out.println("getInputStream is null");

				return body;

			}

			System.out.println("getInputStream not null");

			// 假定消息不超过8192byte

			int bufsize = 8192;

			System.out.println("read start");

			byte[] buf = new byte[bufsize];

			

			int rlen = is.read(buf, 0, bufsize);        //发现在这里阻塞了！

			System.out.println("read end");

			if (rlen <= 0) {

				//Log.i(TAG, "http body read 0 byte!");

				System.out.println("read is null");

				return null;

			}

			System.out.println("read not null,len is"+rlen);

			ByteArrayInputStream hbis = new ByteArrayInputStream(buf, 0, rlen);

			BufferedReader hin = new BufferedReader(new InputStreamReader(hbis));

			body = hin.readLine();

			System.out.println("body is"+body);

			return body;

		} catch (IOException ioe) {

			ioe.printStackTrace();

		}

		return null;

	}

客户端：



class MySender extends Thread {

		@Override

		public void run() {

			// TODO Auto-generated method stub

			super.run();

			try {

				JSONObject request = new JSONObject();

				request.put("action", et.getText().toString());

				HttpPost post = new HttpPost("http://"+ip+":8888");

				post.setEntity(new StringEntity(request.toString()));

				HttpResponse response = new DefaultHttpClient().execute(post);

				String res = EntityUtils.toString(response.getEntity());

				Message msg = new Message();

				msg.obj = res;

				handler.sendMessage(msg);				

			} catch (Exception e) {

				// TODO Auto-generated catch block

				e.printStackTrace();

			}

		}

	}
