Choosing an Output Channel

Creating a DIS Stream

If Output Mode is set to DIS for a task, ensure that a DIS stream is available. For details about how to create a DIS stream, see Creating a DIS Stream.

Starting a Webhook Service

If Output Mode is set to Webhook for a task, ensure that a webhook service has been started.

The following uses a simple Python script as an example to describe how to start a webhook service and save the received data.

1. Prepare a local Linux server, ensure that the network between the Linux server and the edge node server is normal, and install the Python environment.
2. Run the ifconfig command on the Linux server to obtain the IP address.
3. Enter the IP address of the Linux server in line 18 of the script.
   Figure 1 Script example post.py
   

   import json
   from wsgiref.simple_server import make_server
   
   def application(environ, start_response):
       start_response('200 OK', [('Content-Type', 'application/json')])
       request_body = environ["wsgi.input"].read(int(environ.get("CONTENT_LENGTH", 0)))
   
       f=open('./post.txt','a')
       f.write(request_body)
       f.write("\n")
       f.close()
       return ("200 success\n")
   
   if __name__ == "__main__":
       port = 6006
       httpd = make_server("10.10.10.1", port, application)
       print "serving http on port {0}...".format(str(port))
       httpd.serve_forever()

   

   You can change the port number 6006 in the script.

   When creating a task, set the webhook URL to http://${IP address}:${Port}, for example, http://10.10.10.1:6006.

4. Execute the script python post.py to start the webhook service.
