Question

如何通过扩展管道使用python-social-auth从google和facebook检索个人资料图片和出生日期？我已经读过我可以创建函数并设置它们的路径，但我不知道必须检索的属性名称。请帮忙！

Answer 1

要从社交登录获取头像，您需要在应用中创建一个pipeline.py文件，并将此行添加到settings.py：

SOCIAL_AUTH_PIPELINE = (

    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.auth_allowed',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.user.get_username',
    'social.pipeline.user.create_user',
    'social.pipeline.social_auth.associate_user',
    'social.pipeline.social_auth.load_extra_data',
    'social.pipeline.user.user_details',
    'apps.users.pipeline.get_avatar', # This is the path of your pipeline.py
    #and get_avatar is the function.
)

然后将此内容添加到您的pipeline.py文件

def get_avatar(backend, strategy, details, response,
        user=None, *args, **kwargs):
    url = None
    if backend.name == 'facebook':
        url = "http://graph.facebook.com/%s/picture?type=large"%response['id']
    if backend.name == 'twitter':
        url = response.get('profile_image_url', '').replace('_normal','')
    if backend.name == 'google-oauth2':
        url = response['image'].get('url')
        ext = url.split('.')[-1]
    if url:
        user.avatar = url
        user.save()

以下是我用来为Facebook保存图片的内容：

def save_profile_picture(backend, user, response, details,
                         is_new=False,*args,**kwargs):

    if backend.__class__.__name__ == 'FacebookOAuth2':
        up = UserProperties.objects.get_or_create(user=user) #RETURNS TUPLE (instance, created(boolean))
        if not up[0].photo:
            url = 'http://graph.facebook.com/{0}/picture'.format(response['id'])
            response = urllib.request.urlopen(url)
            io = BytesIO(response.read())
            up[0].photo.save('profile_pic_{}.jpg'.format(user.pk), File(io))
            up[0].save()

将此函数保存到文件中，例如pipelines.py，然后将该函数添加到您设置中的SOCIAL_AUTH_PIPELINE。

SOCIAL_AUTH_PIPELINE = (
    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.auth_allowed',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.user.get_username',
    'social.pipeline.social_auth.associate_by_email', 
    'social.pipeline.user.create_user',
    'social.pipeline.social_auth.associate_user',
    'social.pipeline.social_auth.load_extra_data',
    'social.pipeline.user.user_details',
    'projects.pipeline.save_profile_picture', #save facebook profile image,
)

对于Facebook，您需要创建自己的Facebook应用程序。您只能从获得许可的用户处检索信息和图片。同样的规则或多或少适用于Google。请阅读他们的API文档以获取更多详细信息。

上述答案可能不起作用（它对我不起作用），因为如果没有访问令牌，facebook 个人资料 URL 将不再起作用。以下答案对我有用。

def save_profile(backend, user, response, is_new=False, *args, **kwargs):
    if is_new and backend.name == "facebook":
        # The main part is how to get the profile picture URL and then do what you need to do
        Profile.objects.filter(owner=user).update(
            imageUrl='https://graph.facebook.com/{0}/picture/?type=large&access_token={1}'.format(response['id'],
                                                                                                  response[
                                                                                                      'access_token']))
    elif backend.name == 'google-oauth2':
        if is_new and response.get('picture'):
            Profile.objects.filter(owner=user).update(imageUrl=response['picture'])

在setting.py中添加管道，

SOCIAL_AUTH_PIPELINE+ = ('<full_path>.save_profile')

只是为了扩展萨达特的答案，它非常适合保存网址。如果您想将 url 中的实际图像保存到 django 图像字段，则需要执行以下操作：

import requests
from io import BytesIO
from django.core import files

def save_profile(backend, user, response, is_new=False, *args, **kwargs):
if is_new and backend.name == "facebook":
    
    picture_url='https://graph.facebook.com/{0}/picture/?type=large&access_token={1}'.format(response['id'],
                                                                                              response[
                                                                                                  'access_token']))   
    file_name = f"{uuid.uuid4()}.jpeg"
            resp = requests.get(picture_url)
            if resp.status_code == requests.codes.ok:
                fp = BytesIO()
                fp.write(resp.content)
  
                profile.image.save(file_name, files.File(fp))
                profile.save()
