FastAPI - 安全(Security)4

删除routers/member.py文件

修改main.py文件

# -*- coding:utf-8 –*-
from fastapi import Depends,FastAPI

from fastapi.security import OAuth2PasswordBearer
from typing import Annotated

oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token")

app = FastAPI(
    title="文档标题",
    description="关于API文档的补充说明",
    version="1.0.0",
    docs_url="/docs"
)


@app.get("/items/")
async def read_items(token: Annotated[str, Depends(oauth2_scheme)]):
    return {"token": token}

创建用户模型

修改main.py文件

# -*- coding:utf-8 –*-
from fastapi import Depends, FastAPI

from fastapi.security import OAuth2PasswordBearer
from typing import Annotated
from pydantic import BaseModel

oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token")


class User(BaseModel):
    username: str
    email: str | None = None
    full_name: str | None = None
    disabled: bool | None = None


def fake_decode_token(token):
    return User(
        username=token + "fakedecoded", email="vvv@example.com", full_name="vvv lao"
    )


async def get_current_user(token: Annotated[str, Depends(oauth2_scheme)]):
    user = fake_decode_token(token)
    return user

app = FastAPI(
    title="文档标题",
    description="关于API文档的补充说明",
    version="1.0.0",
    docs_url="/docs"
)


@app.get("/users/me")
async def read_users_me(current_user: Annotated[User, Depends(get_current_user)]):
    return current_user

其中get_current_user使用oauth2_scheme作为依赖项
