fastapi 设置Cookie后重定向的demo

当然可以，请参考以下代码：

from fastapi import FastAPI, Response

app = FastAPI()

@app.get("/set-cookie")
def set_cookie(response: Response):
    response.set_cookie(key="example", value="cookie_value")
    response.headers["Location"] = "/get-cookie"
    response.status_code = 302

这是一个简单的示例，在 `/set-cookie` 路径下，我们设置了一个名为 `example` 值为 `cookie_value` 的 cookie，然后将响应状态码设置为 302，并将响应头中的 `Location` 设置为 `/get-cookie`，表示浏览器应该重定向到 `/get-cookie` 路径。最后，我们返回响应对象 `response`。

fastapi Session 设置过期时间 demo

Sure, here's a demo of setting the expiration time for a session in FastAPI:

from fastapi import FastAPI, Request, Response, APIRouter, Depends, HTTPException, status
from fastapi.templating import Jinja2Templates
from fastapi.security import OAuth2PasswordRequestForm
from datetime import timedelta

app = FastAPI()
router = APIRouter()

templates = Jinja2Templates(directory="templates")

def get_settings():
    return settings

# Configurations
class Settings(BaseSettings):
    access_token_expire_minutes: int = 30
    refresh_token_expire_days: int = 30
    api_prefix: str

settings = Settings()

# Session
router = APIRouter()
ACCESS_TOKEN_EXPIRE_MINUTES = settings.access_token_expire_minutes


@router.post("/login/access-token")
async def login_access_token(
    form_data: OAuth2PasswordRequestForm = Depends(),
    session: Session = Depends(get_session),
):
    user = authenticate_user(session, form_data.username, form_data.password)
    if not user:
        raise HTTPException(status_code=400, detail="Incorrect username or password")
    access_token_expires = timedelta(minutes=ACCESS_TOKEN_EXPIRE_MINUTES)
    access_token = create_access_token(
        data={"sub": user.email}, expires_delta=access_token_expires
    )
    return {"access_token": access_token, "token_type": "bearer"}


async def on_startup():
    app.session_cookie_name = "access_token"
    app.include_router(router)
    return


@app.on_event("startup")
async def startup():
    await on_startup()

fastapi表单提交 设置cookie

当用户在 FastAPI 中提交表单时，可以设置 cookie。可以使用 `starlette.middleware.sessions.SessionMiddleware` 中间件来为应用程序添加会话支持，以便将 cookie 和其他会话数据存储在服务器上。要设置 cookie，可以使用 `fastapi.responses.JSONResponse.set_cookie` 方法。
