@mpneon/cloud

微信小程序云函数框架

特性

  • 云函数路由(代码共享)

Usage

路由

使用 app.route() 方法创建路由。

// sum.js
module.exports = (request, { cloud, db, ...context }) => {
    const { a, b } = request.event

    return a + b
}
// index.js
const app = new (require('@mpneon/cloud').Application)();

app.route('sum', require('./sum'))

exports.main = (event, context) => app.handle(event, context);

获取当前请求用户 @since 1.1.0

你可以从 request.user 字段(异步)获取发起当前请求的用户。

// user.js
module.exports = async (request, { cloud, db, ...context }) => {

    const user = await request.user

    return user
}

默认情况下,会从云数据库的 users 集合中查询 _id 为当前 OPENID 的记录。如果你需要自定义解析当前用户的方法,使用 app.useUserResolver((openid, requestcontext) => Promise<any>)

// index.js

app.route('user', require('./user'))

app.useUserResolver((openid, { cloud, db, ...context }) => new Promise(resolve => {
  // 取 users 集合中 openid 字段为 OPENID 的记录
  db.collection("users")
    .where({
      openid
    })
    .get()
    .then(({ data: users}) => resolve(users[0] || null));
}))

exports.main = (event, context) => app.handle(event, context)

定时任务 @since 1.2.0

若要使用定时任务,须根据小程序文档设置一个每分钟执行的定时触发器,然后使用 app.cron() 方法注册你的定时任务。

// task.js
module.exports = (request, { cloud, db, ...context }) => {
    console.log('Taske invoked every other minute')
}
// index.js
const app = new (require('@mpneon/cloud').Application)();

app.route('sum', require('./sum'))

app.cron('*/2 * * * *', require('./task'))

exports.main = (event, context) => app.handle(event, context);

注意 app.cron() 方法只支持标准 Cron 表达式,即不支持秒和年。
