例如，我们可以使用Depends来声明一个依赖项get_db()，该函数创建并返回一个数据库连接。...import Depends, HTTPExceptionfrom sqlalchemy.orm import Sessionfrom database import SessionLocaldef get_db...yield db finally: db.close()@app.get("/items/")async def read_items(db: Session = Depends(get_db...)): return db.query(Item).all()在上面的代码中，我们定义了一个依赖项get_db()，它创建并返回一个数据库连接。...当收到GET请求时，FastAPI将使用Depends解析依赖项get_db()，并将其返回值传递给视图函数read_items()作为参数。
首先，我们从database.py中导入它 from .database import SessionLocal def get_db(): db = SessionLocal() try...: yield db finally: db.close() 然后编写函数get_db()来用于获取sessionLocal以及及时关闭连接。...from fastapi import Depends @app.post('/blog') def new_blog(blog: schemas.Blog, db: Session = Depends(get_db...我们这里的db也就是依赖于get_db()这个函数来生成的。...获取单篇博客 这里我已经把它改造好了： @app.get('/blog/{id}') def showblog(id: int, db: Session = Depends(get_db)):

db = SessionLocal() try: yield db finally: db.close() if EVENT =="test": get_db...=get_test_db else: get_db=get_db_pro 最后在连接数据库的地方，我们把get_db替换成从 from get_db import get_db
