在普通的SQLAlchemy中,建立engine对象,我们会采用下面的方式: from sqlalchemy import create_engine engine = create_engine(SQLALCHEMY_DATABASE_URI, pool_recycle=1500) 1. 2. 而异步的方式如下: from sqlalchemy.ext.asyncio import create_async_engine async_engine = create_async_engine(ASYNC_SQLALCHEMY_U...

与Node.js或Go中相比，Python WSGI Web框架的最大缺点之一是无法异步处理请求。自从引入ASGI以来这一问题就迎刃而解了，FastAPI充分利用了这一点。你要做的就是简单地使用async关键词声明端点，如下所示：@app.post("/")async def endpoint():# ...# call async functions here with `await`# ...return{"...
