Summary of Changes

Hello @kevinlin09, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a significant enhancement to the application's input handling by enabling the processing of a file_list parameter. This feature allows the application to receive and work with file-based content, expanding its capabilities for tasks such as content summarization. The changes include modifications to the input parameter building logic and an updated example to showcase its practical application.

Highlights

• New Feature: file_list Input Support: The core application logic now supports a new file_list parameter, allowing users to pass a list of files as input to the application.
• Updated Example Usage: An existing example has been updated to demonstrate how to use the new file_list parameter, including a prompt for summarizing file content and providing an audio file URL.

Code Review

This pull request adds support for a file_list input parameter to the Application.call method. The implementation in dashscope/app/application.py correctly adds the new parameter to the request. However, it lacks input validation, which could lead to runtime errors. I've added a suggestion to include type checking for the new parameter to improve robustness, similar to how other parameters are handled in the same function. The changes to the sample file in samples/test_application.py look good for demonstrating the new feature.

[gemini-code-assist]

The new file_list parameter is added to input_param without any type validation. This could lead to unexpected behavior or errors downstream if an invalid type is passed. For robustness, you should add validation to ensure file_list is a list of strings, similar to how doc_tag_codes is handled in this function.

Suggested change

	file_list = kwargs.pop('file_list', None)
	if file_list is not None and file_list:
	input_param['file_list'] = file_list
	file_list = kwargs.pop('file_list', None)
	if file_list:
	if isinstance(file_list, list) and all(
	isinstance(item, str) for item in file_list):
	input_param['file_list'] = file_list
	else:
	raise InvalidInput('file_list must be a List[str]')
