获取Facebook用户喜欢Python社交认证 [英] Get Facebook user likes in Python Social Auth

问题描述

我正在使用Django开始一个项目，我试图允许用户使用Facebook登录。为了网站的目的，我想将用户喜欢存储在我的数据库中。

I'm starting a project with Django and I'm trying to allow users log in with Facebook. For the site purposes, I want to store the user likes in my database.

我以Python Social Auth为例（我正在使用的图书馆）对于项目），我已经写了一个管道存储数据在数据库中。

I took as an example the example app on Python Social Auth (the library I'm using for the project) and I've written a pipeline for storing data in DB.

当我尝试访问喜欢时，问题出现，因为我得到的响应的数据只是给我基本的数据，所以以下代码不起作用。

The problem comes when I try to access likes, because the data that the response I get just gives me the basic data, so the following code doesn't work.

def user_details(strategy, details, response, user=None, *args, **kwargs):
    attrs = {'user': user}
    if strategy.backend.__class__.__name__ == 'FacebookOAuth2':
        #no response['likes']
        for i in response['likes']:
            for d in i['data']:
                p = UserPreferences(user=user,like=d['name'])
                p.save()

我在Facebook上的应用程序要求喜欢的权限，我在settings.py上有以下内容（使用secret和al我的东西）：

My app in Facebook asks for likes permissions, and I have the following on my settings.py (with the secret and all that stuff):

SOCIAL_AUTH_SCOPE = ['user_likes']

任何方式使这项工作？

推荐答案

重命名设置 SOCIAL_AUTH_SCOPE 至 SOCIAL_AUTH_FACEBOOK_SCOPE 。您不需要在认证过程中自动发送喜欢的内容，因此您需要将其查询到Facebook API，例如：

Rename the setting SOCIAL_AUTH_SCOPE to SOCIAL_AUTH_FACEBOOK_SCOPE. Likes aren't sent automatically in the auth process, you need to query them to Facebook API, for example:

def get_likes(strategy, details, response, *args, **kwargs):
    if strategy.backend.name == 'facebook':
        likes = strategy.backend.get_json(
            'https://graph.facebook.com/%s/likes' % response['id'],
            params={'access_token': response['access_token']}
        )
        for like in likes['data']:
            pass  # Process and save likes here
