Python

Procedure

1. Write the server.py code. Example:

   import tornado.ioloop
   import tornado.web
   import os
   
   class MainHandler(tornado.web.RequestHandler):    
       def get(self):        
           self.write("GET: Hello world")     
   
       def post(self):        
           self.write("POST: Hello world")
   
   def make_app():    
       return tornado.web.Application([        
           r"/. *", MainHandler),    
       ])
   
   if __name__ == "__main__":    
       app = make_app()    
       port = os.environ.get("FC_SERVER_PORT", "9000")    
       app.listen(int(port))    
       tornado.ioloop.IOLoop.current().start()

2. Write a file named bootstrap to start the HTTP server for the preceding code and grant it the permission to run the code. Example:
   Notice The code must contain the #! /bin/bash comment.

   #! /bin/bash
   python server.py

3. Compress the server.py and bootstrap files into a ZIP package, and then create a function that uses the custom runtime based on this ZIP package.
   Note In this case, the handler of the function is useless. You can enter any string that meets the character set constraints of handlers in Function Compute.
