如何获取摄像头的控制指令数据，进行模拟发送控制

需求：获取网络摄像头的控制指令数据，如关闭RTMP流，修改RTMP 推送地址 ，然后android 端 模拟发送http协议进行控制网络摄像头1：网络摄像头 有控制台 ，如 http://192.168.1.10/cn/home.asp ，可以进行修改参数等操作2：用Fiddler4 进行抓取 网页端发送的http 协议数据 （网上很多教程）3：如下是获取的关闭RTMP 的协议发送 POST http://192.168.1.10/action/set?subject=rtmp HTTP/1.1x-requested-with: XMLHttpRequestAccept-Language: zh-cnReferer: http://192.168.1.10/cn/admin/rtmp.asp Accept: text/html, */*; q=0.01Content-Type: application/x-www-form-urlencoded; charset=UTF-8Accept-Encoding: gzip, deflateUser-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E)Host: 192.168.1.10Content-Length: 479Connection: Keep-AlivePragma: no-cacheCookie: language=zhAuthorization: --------（此处删除账号信息，你懂得。。。）<?xml version="1.0" encoding="utf-8"?><request><rtmp>                  <push>                       <active>0</active>                      <stream>0</stream>                      <url>rtmp://192.168.1.99:1935/452500846393/front</url>                      <tsection>0-86340</tsection>                     <tsection>0-0</tsection>                      <tsection>0-0</tsection>                      <tsection>0-0</tsection>                  </push>               </rtmp></request>从中可以看出 ：url 是 http://192.168.1.10/action/set?subject=rtmp   ，body 是 xml  剩下的中间就是head。 如何通过http封装如下 代码 （用okhttp）package com.example.myapplication;import android.nfc.Tag;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.util.Log;import android.widget.Button;import android.widget.EditText;import java.io.IOException;import butterknife.BindView;import butterknife.ButterKnife;import butterknife.OnClick;import okhttp3.Authenticator;import okhttp3.Call;import okhttp3.Callback;import okhttp3.Credentials;import okhttp3.MediaType;import okhttp3.OkHttpClient;import okhttp3.Request;import okhttp3.RequestBody;import okhttp3.Response;import okhttp3.Route;public class MainActivity extends AppCompatActivity {//active : 0 关 ，1 开//stream : 0 主码流 ， 1 次码流@BindView(R.id.editText_active)EditText editTextActive;@BindView(R.id.editText_stream)EditText editTextStream;@BindView(R.id.editText_url)EditText editTextUrl;@BindView(R.id.btn_submit)Button btnSubmit;OkHttpClient client;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ButterKnife.bind(this);Log.d("google.sang", "onCreate...
