fastapi登录功能

1、登录参数必须是OAuth2PasswordRequestForm类型

• 因为在swagger UI中的登录使用的表单传账号和密码
• 这个类依赖python-multipart，使用前需安装

pip install python-multipart

2、示例代码

@login_router.post("", summary="登录")
def create(form_data: OAuth2PasswordRequestForm = Depends(), db=Depends(get_db)):try:username = form_data.usernamepassword = form_data.username...return Result.failed(msg=f"账号或密码错误！")except Exception as e:logging.error(f"登录报错:{str(e)}")return Result.failed(msg=f"登录报错:{str(e)}")

3、在接口中验证必须登录才能调用接口

from fastapi.security import OAuth2PasswordBeareroauth2_scheme = OAuth2PasswordBearer(tokenUrl="login")@user_router.get("/users/", summary="获取用户列表")
def get_users(db=Depends(get_db), token=Depends(oauth2_scheme)):users = db.query(User).all()data = [to_json(user) for user in users]return Result.succeed(data=data)
