But if you want to use async / await without FastAPI, you can do it as well.Write your own async code¶Starlette (and FastAPI) are based on AnyIO, which makes it compatible with both Python's standard library asyncio and Trio.
But remember that when you import Query, Path, File and others from fastapi, those are actually functions that return special classes. 但是请记住,当您从 fastapi 中导入 Query、Path、File 和其他文件时,这些实际上是返回特殊类的函数。 Tip 提示 To declare File bodies, you need to use File, becau...

Starlette提供了WebSocket支持、中间件等功能,而Pydantic利用Python类型提示在运行时进行数据验证。类型提示允许在编译时检查变量类型,提高开发效率。FastAPI通过Pydantic创建数据模型,确保数据结构的正确性。FastAPI还支持异步I/O,利用Python 3.6+的async/await关键词和ASGI,提高性能。此外,...
The async keyword is used when defining a function to tell Python that such a function will use the await keyword at some point. There are some exceptions to this, such as asynchronous generators. However, this is true for the majority of cases, so no need to worry about it for now. ...

If you don’t know the difference between normal functions and async functions and when to use them, check out Concurrency and async/await in the FastAPI documentation. Step 5 is to return the content: Python # main.py from fastapi import FastAPI app = FastAPI() @app.get("/") async ...
