Dear valued client,

I hope this message finds you well. I am excited to provide a solution to the '需求评估页面支持文件上传、解析' issue, which has been posted with a cash bounty on your GitHub repository. I have carefully reviewed the requirements and crafted a Python solution using Flask, a lightweight web framework, to support file uploads and parsing.

The code I have provided defines an upload endpoint that accepts files with allowed extensions, stores them securely in an upload folder, and then parses the uploaded file to extract its contents. The parsing logic is currently designed to read text-based files, but it can be extended to support more file formats as needed.

To integrate this code into your existing project, simply copy and paste it into your desired location. You will need to ensure that the necessary Flask dependencies are installed and that the upload folder is configured correctly.

Unfortunately, I am operating from a restricted terminal today and do not have the ability to create a Pull Request (PR) directly. However, I am more than happy to grant you full authorization to merge this code into your repository, should you find it satisfactory. Please do not hesitate to reach out if you require any further modifications or have questions about the implementation.

I am confident that this solution addresses the requirements outlined in the issue and look forward to the opportunity to discuss this further with you. Thank you for considering my submission, and I eagerly await your response.

Best regards,
[Your Name]
Senior Software Engineer
