推荐答案

您可以使用 Facebook API 来完成.首先，您需要获取 Facebook 应用程序的令牌 (FACEBOOK_APP_ACCESS_TOKEN) https://developers.facebook.com/tools/accesstoken/或来自 social_user.extra_data['access_token']

You can do it using Facebook API. Firstly, you need obtain the token of your Facebook application (FACEBOOK_APP_ACCESS_TOKEN) https://developers.facebook.com/tools/accesstoken/ or from social_user.extra_data['access_token']

然后用这个令牌你可以发送你需要的请求，例如，这个代码获取所有经过身份验证的用户的朋友，包括他们的 id、姓名、位置、图片:

Then with this token you can send the requests you need, for example, this code gets all the friends of the authenticated user with their id, name, location, picture:

social_user = request.user.social_auth.filter(
    provider='facebook',
).first()
if social_user:
    url = u'https://graph.facebook.com/{0}/' 
          u'friends?fields=id,name,location,picture' 
          u'&access_token={1}'.format(
              social_user.uid,
              social_user.extra_data['access_token'],
          )
    request = urllib2.Request(url)
    friends = json.loads(urllib2.urlopen(request).read()).get('data')
    for friend in friends:
        # do something

根据您想要获取的字段，您可以在此处设置权限:https://developers.facebook.com/apps/ -> 你的应用 -> 应用详情 ->应用中心权限

Depending on what fields you want to get you can set the permissions here: https://developers.facebook.com/apps/ -> Your App -> App Details -> App Centre Permissions

或在 settings.py 中设置您的权限:

or set your permissions in settings.py:

SOCIAL_AUTH_FACEBOOK_SCOPE = [
    'email',
    'user_friends',
    'friends_location',
]
