Flask设置、获取、删除cookies

1、设置cookies

@app.route('/login/', methods=["GET", "POST"])
def login():
    if request.method == "POST":
        form_data = request.form
        username = form_data.get("username")
        password = form_data.get("password")
        user = User.query.filter_by(username=username).first()
        if  spw(password)==user.password:
            response = redirect('/index/')
            response.set_cookie("user_id",str(user.id))
            return response
    return render_template('login.html', **locals())

2、获取cookies

@app.route('/loginvalid/')
def  loginValid(fun):
    def  inner (*args,**kwargs):
        id=request.cookies.get("user_id")
        print(id)
        if id:
            print(id)
            user=User.query.get(str(id))
            if user:
                print(user)
                return  fun(*args,**kwargs)
        return redirect("/login/")
    return inner

3、删除cookies

@app.route('/logout/',methods=["GET","POST"])
def  logout():
    response=redirect("/login/")
    response.delete_cookie("user_id")
    return response
