Oracle Drags Its Feet in the JavaScript Trademark Dispute
Oracle seeks to dismiss fraud claims in the JavaScript trademark dispute, delaying the case and avoiding questions about its right to the name.
@mpneon/cloud
Advanced tools
微信小程序云函数框架
新建一个云函数 neon
,安装 @mpneon/cloud
作为它的依赖。
使用 app.route()
方法创建路由。
// sum.js
module.exports = (request) => {
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);
在小程序端调用时,调用云函数 neon
,并传入 $path
字段表示要访问的函数路由。
// app.js
wx.cloud.callFunction({
// 云函数名称
name: 'neon',
// 传给云函数的参数
data: {
$path: 'sum',
a: 1,
b: 2,
},
success: function(res) {
console.log(res.result) // 3
},
fail: console.error
})
你可以使用 use('db')
方法来获取云数据库实例。
// users.js
module.exports = (request) => {
const db = use('db')
const { data } = await db.collection('users').get()
return data
}
全局方法 use()
还可用于获取其它模块实例,如:
use('cloud')
获取 wx.cloud
你可以从 request.user
字段(异步)获取发起当前请求的用户。
// users.js
module.exports = async (request) => {
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) => new Promise(resolve => {
const db = use('db')
// 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)
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。
// config.json
{
"triggers": [
{
"name": "neon.schedule",
"type": "timer",
"config": "0 * * * * * *"
}
]
}
然后使用 app.cron()
方法注册你的定时任务。
// task.js
module.exports = (request) => {
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。
