配置

// config/config.${env}.js
exports.weappAuth = {
  appId: 'xxxxxxxxxxx',
  appSecret: 'xxxxxxxxxxxxxxxxxx'
};

使用方式

// app/router.js
module.exports = app => {
  const { router, controller } = app
  const authorization = app.middleware.authorization()
  const validation = app.middleware.validation()

  // user
  router.get('/login', authorization, controller.user.login)
  router.get('/user', validation, controller.user.validate)
};

// app/controller/user.js
const Controller = require('egg').Controller

class UserController extends Controller {
  async validate() {
    const { ctx } = this
    if (ctx.state.$wxInfo.loginState === 1) {
      // loginState 为 1，登录态校验成功
      ctx.state.data = ctx.state.$wxInfo.userinfo
    } else {
      ctx.state.code = -1
    }
  }

  async login() {
    const { ctx, app } = this

    if (ctx.state.$wxInfo.loginState) {
      ctx.state.data = ctx.state.$wxInfo.userinfo
      ctx.state.data['time'] = Math.floor(Date.now() / 1000)
    }
  }
}

module.exports = UserController
