- 向 `.env` 文件中添加以下内容并保存。请将 `<Your OpenAI API Key>` 占位符更改为您的实际 OpenAI API Key。

  ```properties
  OPENAI_API_KEY=<Your OpenAI API Key>

  TIDB_HOST=${LAB:SERVERLESS_CLUSTER_HOST}
  TIDB_PORT=${LAB:SERVERLESS_CLUSTER_PORT}
  TIDB_USERNAME='${LAB:SERVERLESS_CLUSTER_USERNAME}'
  TIDB_PASSWORD='${LAB:SERVERLESS_CLUSTER_PASSWORD}'
  TIDB_DATABASE=${LAB:SERVERLESS_CLUSTER_DATABASE_NAME}
  ```
