Small micro-channel routing reform program

A user can only create 50 cloud function in a cloud environment, we can create multiple routing function in a cloud, which can reduce the number of cloud function.

Raja on small micro-channel pull-down refresh program contained articles to achieve a single song by calling cloud function, now to be rehabilitated by routing tcb-router

Right cloud music function, click open terminal

enter the following command to install tcb-router

npm install --save tcb-router

js cloud music file function modified as follows:

// 云函数入口文件
const cloud = require('wx-server-sdk')
const TcbRouter = require('tcb-router')
const rp = require('request-promise')
cloud.init()
// 云函数入口函数
exports.main = async (event, context) => {
  const app = new TcbRouter({
    event
  })
  app.router('playlist', async (ctx, next) => {
    ctx.body = await cloud.database().collection('playlist')
      .skip(event.start)
      .limit(event.count)
      .orderBy('createTime', 'desc')
      .get()
      .then((res) => {
        return res
      })
  })
  return app.serve()
  // const playlist = await cloud.database().collection('playlist')
  //   .skip(event.start)
  //   .limit(event.count)
  //   .orderBy('createTime', 'desc')
  //   .get()
  //   .then((res) => {
  //     console.log(res)
  //     return res
  //   })
  // return playlist
}

We can also create a list of songs musiclist routing, routing lyric lyrics, songs address musicUrl routing in the cloud music function, so that multiple similar functions into a cloud to function, distinguished by routing, reducing the creation of cloud function.

Upload cloud function

Add the following code to the red box in the demo.js.
