如何在flask-login中跟踪当前用户？ [英] How to track the current user in flask-login?

问题描述

我尝试从flask-login中使用我的视图中的当前用户。所以我试图 g object

我分配 flask.ext.login.current_user to g object

  @ pot.before_request 
 def load_users（）：
 g.user = current_user.username 
  

如果用户正确，但是，当我做注册或以错误的凭据登录
我得到这个错误

AttributeError ：'AnonymousUserMixin'对象没有属性'username'

请让我知道我在哪里错了...

解决方案

感谢你的回答@Joe和@pjnola，正如你所有的建议我提到 flask-login docs

我发现我们可以自定义匿名用户类，所以我为我定制要求，

匿名类

 ＃！/ usr / bin / python 
＃flask-login匿名用户类$ b $ from flask.ext.login import AnonymousUserMixin 
 class匿名（AnonymousUserMixin）：
 def __init __（self）：
 self.username ='Guest'
  

类到 anonymous_user

login_ma nager.anonymous_user =匿名

如果是匿名请求，则可以获取用户名。

I m trying to use the current user in my view from flask-login. So i tried to g object

I m assigning flask.ext.login.current_user to g object

@pot.before_request
 def load_users():
   g.user = current_user.username

It works if the user is correct. But when i do sign-up or login as with wrong credentials I get this error

AttributeError: 'AnonymousUserMixin' object has no attribute 'username'

Please enlight me where am i wrong...

解决方案

Thanks for your answer @Joe and @pjnola, as you all suggested i referred flask-login docs

I found that we can customize the anonymous user class, so i customized for my requirement,

Anonymous class

#!/usr/bin/python
#flask-login anonymous user class
from flask.ext.login import AnonymousUserMixin
class Anonymous(AnonymousUserMixin):
  def __init__(self):
    self.username = 'Guest'

Then added this class to anonymous_user

login_manager.anonymous_user = Anonymous

From this it was able to fetch the username if it was anonymous request.
