Advanced 高级

Here you will find more detailed documentation and examples covering the more advanced features and functionality of the platform.
在这里，您将找到更详细的文档和示例，涵盖平台的更高级特性和功能。

Note
The API Reference documentation should be considered the source of truth for the platform. If there are any discrepancies between concepts described here and the API Reference, then the API Reference should be considered the correct information. We are working to ensure that concepts stay up-to-date with the API Reference and will be introducing doc tests in the near future to help with this.

注意
API 参考文档应被视为平台的真实来源。如果这里描述的概念与 API 参考之间存在任何不一致，则应将 API 参考视为正确信息。我们正在努力确保概念与 API 参考保持最新，并将在不久的将来引入文档测试以帮助实现这一目标。
