Question

我想使用以下登录功能。将JWT令牌保存在cookie中之后，我想重定向到用户home。

@app.route("/login", methods=['GET','POST'])
def login():
    signInform = LoginForm()
    examForm = PersonExamForm()
    online_users = mongo.db.users.find({"online": True})
    try:
        render_template('login.html', title = 'Login', form =signInform) db_cm.find_one({'username':signInform.username.data}) 
        if auth != None:
            print(signInform.password.data == auth['password'])
            if signInform.password.data == auth['password']:       
               access_token = create_access_token(identity=auth['username'], expires_delta=datetime.timedelta(minutes=1), user_claims=None, headers=None)
               refresh_token =create_refresh_token(identity=auth['username'], expires_delta=datetime.timedelta(minutes=1), user_claims=None, headers=None)
            # Set the JWT cookies in the response                
               resp = jsonify({'login': True})
               set_access_cookies(resp, access_token)
               set_refresh_cookies(resp, refresh_token)               
               return resp,200, render_template('home.html', posts = sample_posts, online_users=online_users)

它不起作用，我收到一条错误消息：

您可能正在寻找类似这样的东西：

resp = make_response(render_template(*args))
set_access_cookies(resp, access_token)
set_refresh_cookies(resp, refresh_token)               
return resp, 200
