如何在Flask中并行返回jsonify对象和渲染模板 [英] How to return jsonify object and render template parallel in Flask
问题描述
我要使用以下登录功能.将JWT令牌保存在cookie中之后，我想重定向到用户home.
I want use the following login function. After JWT token is saved in cookies , I want to redirect to user 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:
It doesn't work, I get an error message:
ValueError:没有足够的值可解包(预期2，得到1)

推荐答案
您可能正在寻找类似这样的东西:
You probably are looking for something like this instead:
resp = make_response(render_template(*args))
set_access_cookies(resp, access_token)
set_refresh_cookies(resp, refresh_token)
return resp, 200
