5 删除

1-1 加载页面

在controller 文件夹 新建 doDelete.js

'use strict';
const Controller = require('egg').Controller;
const { ObjectId } = require("mongodb")
class DoDeleteController extends Controller {
    async index() {
        const { ctx } = this;
        var { _id } = ctx.query;
        var db = this.app.mongodb;
        const collection = await db.collection('member');
      //找到对应id并删除
        var dele = await collection.deleteOne({ _id: ObjectId(_id) });
        console.log(dele);
      //跳转回home页面
        await ctx.redirect("/home")
    }
}
module.exports = DoDeleteController;

对应路由

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

通过 home.html 传值
