The controller base class BaseController

You can encapsulate common methods in your application by customizing the Controller base class.

1. Create a folder called core under the app folder and create base.js in it

'use strict';

const Controller = require('egg').Controller;

class BaseController extends Controller {
  async success() {
    await this.ctx.render('success')}}module.exports = BaseController;
Copy the code

2. The controller that needs to use the base class method changes the controller inheritance source

'use strict';

const BaseController = require('.. /core/base.js');

class UserController extends BaseController {
  async doLogin() {
    console.log(this.ctx.request.body);
    await this.success(); }}module.exports = UserController;
Copy the code

3. The encapsulated methods are already on this

await this.success();
Copy the code
