Function

This API is used to obtain the script signature information, including script name, input and output parameters, declared class names, and method names. It is synchronous, meaning the invocation result is returned only after the function execution is complete.

This API can be called only when you save or save as a script. If the type of an input or output parameter defined in the script is incorrect, an error message is reported when this API is called.
