How Does a Function Obtain the Request Path or Parameters When Using an APIG Trigger?

By default, the request path or parameters are included in event. A function invokes APIG using its event template. You can obtain the request path or parameters from the function execution result.

Example:

• queryStringParameters: parameters following the question mark (?), separated with ampersands (&). These parameters are added in the URL of a GET request, and will be transferred in the URL string format when a GET request is initiated.
• path: API URL.

You can call an API using its request path. Example: https://464d86ec641d45a683c5919ac57f3823.apig.projectID.huaweicloudapis.com/apig-demo/subpath

Alternatively, you can call an API by adding request parameters. Example:
