Explanation
Invoking Functions
You can invoke a functionthat you've deployed to Oracle Functions in different ways:
1. Using the Fn Project CLI.
2. Using the Oracle Cloud Infrastructure CLI.
3. Using the Oracle Cloud Infrastructure SDKs.
4. Making a signed HTTP request to the function's invoke endpoint. Every function has an invoke endpoint.
Using the Fn Project CLI to Invoke Functions
To invoke a function deployed to Oracle Functions using the Fn Project CLI:
Log in to your development environment as a functions developer.
In a terminal window, enter:
$ fn invoke <app-name> <function-name>
Using SDKs to Invoke Functions:
If you're writing a program to invoke a function in a language for which an Oracle Cloud Infrastructure SDK exists, Oracle recommends you use that SDK to send API requests to invoke thefunction. Among other things, the SDK will facilitate Oracle Cloud Infrastructure authentication.
