Required: Required parameters in YAML mode and CLI mode
C-Required: Required parameters in CLI mode
Y-Required: Required parameters in Yaml mode
Optional: Non mandatory parameter
✋ The difference between Yaml mode and CLI mode: https://github.com/Serverless-Devs/Serverless-Devs/blob/docs/docs/zh/yaml_and_cli.md
Event Format
Quickly obtain the data structures of different events through the command [s cli fc-event -h]
Examples with Yaml
$ s invoke
Examples with CLI
$ s cli fc invoke --region cn-hangzhou --service-name serviceName --function-name functionName --event evnetString

- 有资源描述文件(Yaml)时,可以直接执行
s invoke
进行线上函数的调用; - 纯命令行形式(在没有资源描述 Yaml 文件时),需要指定服务所在地区以及服务名称,函数名等,例如
s invoke --region cn-hangzhou --service-name fc-deploy-service --function-name http-trigger-py36
上述命令的执行结果示例:

Hello world!
在进行调用时,如果需要指定相对应的事件,例如oss的事件,cdn的事件......这些事件的格式,可以通过命令s cli fc-event
获取:
方法 | 方法说明 | 入参示例 | 命令行调用示例 |
---|---|---|---|
http | HTTP 触发器事件 | s cli fc-event http | |
cdn | CDN 触发器事件 | s cli fc-event cdn | |
mns | MNS 触发器事件 | s cli fc-event mns | |
oss | OSS 触发器事件 | s cli fc-event oss | |
sls | SLS 触发器事件 | s cli fc-event sls | |
tablestore | TableStore 触发器事件 | s cli fc-event tablestore |
例如:如果使用oss的事件,进行测试,此时可以执行:s cli fc-event oss
,完成之后,可以看到系统提醒的相对路径信息:
OSS event template created successfully.
👓 Event Template Path: event-template/oss-event.json
You could user fc/fc-api component invoke method and specify the event.
E.g: [s projectName invoke --event-file event-template/oss-event.json]
More information about OSS Trigger:
📝 https://help.aliyun.com/document_detail/74763.htm
此时,可以利用该路径的模板(可以额外进行修改)触发函数,例如:s invoke --event-file event-template/oss-event.json
