Python 被烧瓶教程中的一个关键错误卡住了

My config.py：

OPENID_PROVIDERS = [
{ 'name': 'Google', 'url': 'https://www.google.com/accounts/o8/id' },
{ 'name': 'Yahoo', 'url': 'https://me.yahoo.com' },
{ 'name': 'AOL', 'url': 'http://openid.aol.com/<username>' },
{ 'name': 'Flickr', 'url': 'http://www.flickr.com/<username>' },
{ 'name': 'MyOpenID', 'url': 'https://www.myoopenid.com' }
]

app.config.from_object('config')

教程还活着

谢谢你的帮助

提前感谢

问题在下面一行：

providers=app.config['OPENID_PROVIDERS'])

app.config字典的键“OPENID\u PROVIDERS”不存在。自从从config.py文件加载配置以来，您是否也执行了以下操作：

OPENID_PROVIDERS = [
{ 'name': 'Google', 'url': 'https://www.google.com/accounts/o8/id' },
{ 'name': 'Yahoo', 'url': 'https://me.yahoo.com' },
{ 'name': 'AOL', 'url': 'http://openid.aol.com/<username>' },
{ 'name': 'Flickr', 'url': 'http://www.flickr.com/<username>' },
{ 'name': 'MyOpenID', 'url': 'https://www.myoopenid.com' }
]

app.config.from_object('config')

请在此处阅读更多文档：

您需要添加视图.py以下内容：

from flask import flash, redirect
from app import app
from .forms import LoginForm

在config.py中

CSRF_ENABLED = True
SECRET_KEY = 'your-secret-key'

您可以共享整个堆栈跟踪吗？请共享login.html模板的代码以及错误堆栈跟踪。
