云函数开发工具 alicf

设置阿里云调用参数

./cloudfunctions/config.json

{
   
    "accessKeyId": "Your Aliyun AccessKeyId",
    "accessKeySecret": "Your Aliyun AccessKeySecret",
    "spaceId": "Your Aliyun Serverless SpaceId"
}

创建云函数

会在Serverless空间创建函数

Command:

npm run cf create test-demo

部署云函数

将云函数部署部署到Serverless空间

Command:

npm run cf deploy test-demo

运行云函数

运行Serverless空间云函数

Command:

npm run cf invoke test-demo [参数, 默认为{}]

添加触发器

给Serverless云函数添加触发器

• 1. 参考: https://help.aliyun.com/document_detail/435821.html?spm=a2c4g.435907.0.0.7a8a1fc7WTaC6O
• 1. 编辑触发器参数
     ./cloudfunctions/config.json

     "triggers": {
            
            "test-demo": {
             // 函数名
                "cron": "0 */20 7-16 * 4-6 *",
                "payload": ""
            }
        }
     

     • test-demo: 函数名
     • cron: 触发表达式
     • payload: 定时触发传入参数

Command:

npm run cf trigger test-demo

变量说明

• alicf: 对象存储

  • db: 云数据库操作对象
  • file: 云文件操作对象
  • cloudfunction: 云函数操作对象, 调用其他云函数 cloudfunction.invoke(funcName)
  • httpclient: HTTP请求工具, https://help.aliyun.com/document_detail/435817.html

• alicf.get

  const {
       db, file, cloudfunction, httpclient} = alicf.get()
  

  db 补充文档

  查询集合数量 count

                ...data,
                time: Date.now()
            }
        })

Response:

{
   "success":true,"affectedDocs":0,"result":{
   "ok":1,"n":0,"nModified":0,"upserted":null}}
