1、下载tcb-router包

cnpm i tcb-router -D

2、引入tcb-router包

const TcbRouter = require('tcb-router');

3、初始化router包

在main内部执行（cloud初始化后）const app = new TcbRouter({    event});

4、使用路由

app.use(async(ctx, next) => {    ctx.body = {};    console.log(ctx)    await next()})// 设置numberapp.router(["addNumber",'cutNumber'],async (ctx,next)=>{let number = ctx._req.url == "addNumber"?1:-1try{  let data = await db.collection('num').doc("781218b5-c0a7-4453-befe-a02b58b6a921").update({    data:{      num: db.command.inc(number)    }  })  ctx.body = { data: "", code: 1, msg: "操作成功" }}catch(e){  ctx.body = { data: "", code: 0, msg: "操作失败,"+e }}})// 获取numberapp.router('getData', async(ctx, next) => {try {  let data = await db.collection('num').get();  ctx.body = {    data: data.data,    code: 1  }  await next()} catch (e) {  ctx.body = {    data: "",    code: 0,    msg: e  }  await next()}})return app.serve();
