Writing steps for Nginx handler

Handler's writing steps

Well, here we go, let's sort things out a little bit and review the steps to implement a handler:

1. Write the basic structure of the module. Includes the definition of the module, the module context structure, the configuration structure of the module, etc.
2. Implements handler's mount function. Choose the correct mounting method according to the requirements of the module.
3. Write the handler handler handler. The function of the module is mainly accomplished by this function.

It doesn't look that hard, does it? O r that old saying, there is nothing difficult in the world, only afraid of people with hearts! Now let's fully analyze the functionality and code of the hello handler module example mentioned earlier.
