/// tip | 提示

你可以使用 `async` 或普通函数。

**FastAPI** 会像处理普通依赖一样对它们进行正确处理。

///

## 同时使用 `yield` 和 `try` 的依赖项 { #a-dependency-with-yield-and-try }

如果你在带有 `yield` 的依赖中使用了 `try` 代码块，那么当使用该依赖时抛出的任何异常你都会收到。

例如，如果在中间的某处代码中（在另一个依赖或在某个 *路径操作* 中）发生了数据库事务“回滚”或产生了其他异常，你会在你的依赖中收到这个异常。

因此，你可以在该依赖中用 `except SomeException` 来捕获这个特定异常。
