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/1.1
x-requested-with: XMLHttpRequest

<?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）

        client = new OkHttpClient.Builder().authenticator(new Authenticator() {

            }

                }
            }
        });

    }


    private String getURL(){

        StringBuilder sBuider = new StringBuilder();

        sBuider.append("<?xml version=\"1.0\" encoding=\"utf-8\"?><request><rtmp> <push>");
        sBuider.append("<active>"+editTextActive.getText().toString().trim()+"</active>");
        sBuider.append("<stream>"+editTextStream.getText().toString().trim()+"</stream>");
        sBuider.append("<url>"+editTextUrl.getText().toString().trim()+"</url>");

        Log.i("YYH","getURL-->"+sBuider.toString());
