これは **大規模なコードベース** で、**同じ依存関係** を **多くの *path operation*** で何度も使う場合に特に役立ちます。 ## `async`にするかどうか { #to-async-or-not-to-async } 依存関係は **FastAPI**(*path operation 関数*と同じ)からも呼び出されるため、関数を定義する際にも同じルールが適用されます。 `async def`や通常の`def`を使用することができます。 また、通常の`def`*path operation 関数*の中に`async def`を入れて依存関係を宣言したり、`async def`*path operation 関数*の中に`def`を入れて依存関係を宣言したりすることなどができます。 それは重要ではありません。**FastAPI** は何をすべきかを知っています。Created: Sun Apr 05 07:19:11 GMT 2026 - Last Modified: Fri Mar 20 14:07:17 GMT 2026 - 11.9K bytes - Click Count (0) -

### 文件与异步 { #files-and-async } 大多数情况下,类文件对象默认与 async 和 await 不兼容。 例如,它们没有 `await file.read()`,也不支持 `async for chunk in file`。 而且很多情况下,读取它们是一个阻塞操作(可能会阻塞事件循环),因为数据来自磁盘或网络。 /// info | 信息 上面的示例其实是个例外,因为 `io.BytesIO` 对象已经在内存中,所以读取它不会阻塞。 但在许多情况下,读取文件或类文件对象会发生阻塞。 /// 为避免阻塞事件循环,你可以简单地把*路径操作函数*声明为常规的 `def`(而不是 `async def`),这样 FastAPI 会在一个线程池工作线程上运行它,从而避免阻塞主事件循环。Created: Sun Apr 05 07:19:11 GMT 2026 - Last Modified: Fri Mar 20 14:29:48 GMT 2026 - 5.2K bytes - Click Count (0) -
