推荐答案

您可以使用Facebook API。首先，您需要获取您的Facebook应用程序的标记（ FACEBOOK_APP_ACCESS_TOKEN ） https://developers.facebook.com/tools/accesstoken/
或从 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，使用这个令牌，您可以发送所需的请求，例如，该代码通过身份，名称，位置和图片获取已验证用户的所有朋友： p>

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

根据您要获取的字段，您可以在此处设置权限：
https://developers.facebook.com/apps/ - >您的应用程序 - >应用详细信息 - >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：

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