routing----router

Route describes the correspondence between the request URL and the Controller that is responsible for executing the action.To put it bluntly, when users access different paths, there should be different Controllers to respond to different content.

router.get('/getdata', controller.form.get);//Static routing

Template syntax:

'use strict';

/**

* @param {Egg.Application} app - eggapplication

*/

module.exports = app => {

  const { router, controller } = app;

  router.get('/', controller.home.index);

};

Route matching process:

1. Whenever a request arrives at the server, it needs to be matched by the route first. Only after the match is successful, the corresponding processing function will be called.
2. When matching, it will be matched according to the order of routing configuration; if the request type and request URL are matched successfully at the same time, EXpress will hand over the request to the corresponding function for processing.

Note:

Match in the defined order

Request type and requestURLThe corresponding function will be called only if the match is successful at the same time

When registering a route, the route name should not conflict with the static file name, otherwise static resources will be preferentially accessed.When the route names are the same, the one registered first is executed first
