Code & Preview

• :smiley_cat:source code
• In order to successfully deploy this sample code, you need to provide the following parameters during the deployment process:
  • Region: You need to configure the region where your Function Compute service needs to be deployed through this parameter. The default value is cn-hangzhou (Hangzhou).
  • The geographic options available to you are:
    • cn-beijing (Beijing)
    • cn-hangzhou (Hangzhou)
    • cn-shanghai (Shanghai)
    • cn-qingdao (Qingdao)
    • cn-zhangjiakou (Zhangjiakou)
    • cn-huhehaote (Hohhot)
    • cn-shenzhen (Shenzhen)
    • cn-chengdu (Chengdu)
    • cn-hongkong (Hong Kong)
    • ap-southeast-1 (Singapore)
    • ap-southeast-2 (Sydney)
    • ap-southeast-3 (Kuala Lumpur)
    • ap-southeast-5 (Jakarta)
    • ap-northeast-1 (Tokyo)
    • eu-central-1 (Frankfurt)
    • eu-west-1 (London)
    • us-west-1 (Silicon Valley)
    • us-east-1 (Virginia)
    • ap-south-1 (Mumbai)
  • Service name: You need to name your Function Compute service. The service name can only contain letters, numbers, underscores and dashes. Cannot start with a number or a dash. The length is between 1-128, and the default value is timer-trigger-quick-start.
  • Function name: You need to name your function calculation function. The function name can only contain letters, numbers, underscores and dashes. Cannot start with a number or a dash. The length is between 1-64. The default is timer-trigger-event-function-java11.
  • Time trigger expression (cronExpression): You need to fill in the expression to trigger the function. The time trigger expression supports two settings: @every, cron expression. For example: @every 1m / @every 1h30m.
  • Input content (payLoad): represents the input content of the trigger event itself.

Deployment & Experience

• :fire: Through Serverless Application Center, the application.

• Deploy via Serverless Devs Cli:

  • Install Serverless Devs Cli Developer Tools, and perform Authorization Information Configuration;
  • Initialize the project: s init timer-trigger-fc-event-java11 -d timer-trigger-fc-event-java11
  • Fill in the parameters described in the above modules
  • Enter the project and deploy the project: cd timer-trigger-fc-event-java11 && s deploy -y

• local debugging

  • Enter the application project project and execute the following command: s invoke --event-file event-example/timer-fc-sample.json.

  • You can view the logs and results after the simulated event triggers the function.
