🛠 Guidelines to remediate hardcoded secrets
- Understand the implications of revoking this secret by investigating where it is used in your code.
- Replace and store your secret safely. Learn here the best practices.
- Revoke and rotate this secret.
- If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.
To avoid such incidents in the future consider
- following these best practices for managing and storing secrets including API keys and other credentials
- install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
🦉 GitGuardian detects secrets in your source code to help developers and security teams secure the modern development process. You are seeing this because you or someone else with access to this repository has authorized GitGuardian to scan your pull request.

嗨 @KouShenhai - 我已经审查了你的更改 - 这里有一些反馈：
总体评论：
- 考虑在整个代码库中标准化错误代码格式。目前混合使用了类似 'B_User_NotExist' 和 'S_DS_OperationError' 的格式。建议为所有错误代码选择一种一致的格式。
这是我在审查期间查看的内容
- 🟡 一般问题：发现2个问题
- 🟢 安全性：一切看起来都很好
- 🟢 测试：一切看起来都很好
- 🟢 复杂性：一切看起来都很好
- 🟢 文档：一切看起来都很好
帮助我变得更有用！请点击每条评论上的 👍 或 👎，我将使用反馈来改进你的评论。

Hey @KouShenhai - I've reviewed your changes - here's some feedback:
Overall Comments:
- Consider standardizing error code formats across the codebase. Currently mixing formats like 'B_User_NotExist' and 'S_DS_OperationError'. Suggest picking one consistent format for all error codes.
Here's what I looked at during the review
- 🟡 General issues: 2 issues found
- 🟢 Security: all looks good
- 🟢 Testing: all looks good
- 🟢 Complexity: all looks good
- 🟢 Documentation: all looks good
