你也可以在类型注解中使用 `Response` 的子类：

{* ../../docs_src/response_model/tutorial003_03_py310.py hl[8:9] *}

这同样可行，因为 `RedirectResponse` 是 `Response` 的子类，FastAPI 会自动处理这个简单场景。

### 无效的返回类型注解 { #invalid-return-type-annotations }

但当你返回其他任意对象（如数据库对象）而它不是有效的 Pydantic 类型，并在函数中按此进行了注解时，FastAPI 会尝试基于该类型注解创建一个 Pydantic 响应模型，但会失败。

## Troubleshooting

### Common Migration Issues

#### Issue: Import fails with "Invalid format"

**Solution**:
- Ensure NDJSON files have one valid JSON object per line
- Check for UTF-8 encoding
- Validate JSON syntax with `jq`:
  ```bash
  cat documents.ndjson | jq empty
  ```
