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

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
