我正在尝试使用Django Social Auth包与 Twitter 连接，但我很难理解如何做到这一点，因为我找不到任何示例。我假设这Django Social Auth是用于此目的的最佳包。

我查看了一些使用 Facebook 的示例，并从中将以下内容添加到我的settings.py文件中：

AUTHENTICATION_BACKENDS = (
    'social_auth.backends.twitter.TwitterBackend',
    'django.contrib.auth.backends.ModelBackend',
)

# overwriting default templates
TEMPLATE_CONTEXT_PROCESSORS = (    
    'django.core.context_processors.static',
    'django.core.context_processors.debug',
    'django.core.context_processors.i18n',
    'django.core.context_processors.media',
    'django.contrib.messages.context_processors.messages',
    'social_auth.context_processors.social_auth_by_type_backends',
    'django.contrib.auth.context_processors.auth',
)

SOCIAL_AUTH_ENABLED_BACKENDS = ('twitter')
SOCIAL_AUTH_DEFAULT_USERNAME = 'new_social_auth_user'

# Social media login info:
TWITTER_CONSUMER_KEY         = 'xxx'
TWITTER_CONSUMER_SECRET      = 'xxxxxx'

# 'magic' settings
SOCIAL_AUTH_COMPLETE_URL_NAME = 'socialauth_complete'
SOCIAL_AUTH_ASSOCIATE_URL_NAME = 'associate_complete'

SOCIAL_AUTH_PIPELINE = (
    'social_auth.backends.pipeline.social.social_auth_user',
    'social_auth.backends.pipeline.associate.associate_by_email',
    'social_auth.backends.pipeline.misc.save_status_to_session',
    'social.pipeline.redirect_to_form',
    'social.pipeline.username',
    'social_auth.backends.pipeline.user.create_user',
    'social_auth.backends.pipeline.social.associate_user',
    'social_auth.backends.pipeline.social.load_extra_data',
    'social_auth.backends.pipeline.user.update_user_details',
    'social_auth.backends.pipeline.misc.save_status_to_session',
    'social.pipeline.redirect_to_form2',
    'social.pipeline.first_name',
)

SOCIAL_AUTH_FORCE_POST_DISCONNECT = True
SOCIAL_AUTH_SESSION_EXPIRATION = False

在urls.py我添加了以下几行：

url('', include('social_auth.urls')),
url(r'^twitter/', twitter_app, name='twitter_app')

在一个名为的文件中，twitter.py我添加了以下内容来创建一个视图：

from django.contrib.auth import BACKEND_SESSION_KEY
from django.contrib.auth.models import AnonymousUser
from django.http import HttpResponse
from django.http import HttpResponseRedirect #dq
from django.shortcuts import render_to_response
from django.template.context import RequestContext

from django.views.decorators.csrf import csrf_exempt
from django.core.cache import cache

from social_auth.models import UserSocialAuth
from social_auth.views import complete as social_complete
from social_auth.utils import setting
from social_auth.backends.twitter import TwitterBackend


# twitter login    
def twitter_app(request):
    """twitter login"""
    if request.user.is_authenticated():
        return HttpResponseRedirect('done')
    else:
        return render_to_response('twitter.html', {'twitter_app_id':setting('TWITTER_CONSUMER_KEY'),
                                                'warning': request.method == 'GET'}, RequestContext(request))

然后我创建了一个名为twitter.html以下结构的模板文件：

{% extends "base.html" %}

{% block script %}

Login with <a href="{% url socialauth_begin 'twitter' %}">Twitter</a>

{% endblock %}

这会导致以下错误消息：

http://example.com/twitter/done上的网页导致了过多的重定向。

我对我应该做的整体有点迷茫。我在 twitter 上用我的网站 url 创建了一个应用程序来生成 api/secret 密钥。任何关于我应该走的方向的建议，或工作示例的链接将不胜感激。

我会给你一个示例，这是一个自定义的 twitter 登录，

  1. 该应用程序的名称是社交的
  2. 点安装 Twython
  3. 创建 LOGIN_REDIRECT_URL、TWITTER_SECRET 和 TWITTER_KEY

设置.py

# Twitter settings
TWITTER_KEY = 'xxxxxx'
TWITTER_SECRET = 'xxxxxxxx'

模型.py

class TwitterProfile(models.Model):
    user = models.ForeignKey(User)
    oauth_token = models.CharField(
        max_length=200
        )
    oauth_secret = models.CharField(
        max_length=200
        )
    screen_name = models.CharField(
        max_length=50, 
        blank=True, null=True
        )

    def __unicode__(self):
        return "{0}".format(self.user)

网址.py

urlpatterns = patterns('social.views',      
    url(
        r'^twitter/login/$', 
        "twitter_login", 
        name="twitter_login"
    ),

    url(r'^twitter/callback/$', 
        "twitter_callback", 
        name="twitter_callback"
    ),   
)

视图.py

def twitter_login(request):
    twitter = Twython(
        twitter_token = settings.TWITTER_KEY,
        twitter_secret = settings.TWITTER_SECRET,
        callback_url = request.build_absolute_uri(reverse('social:twitter_callback'))
    )
    auth_props = twitter.get_authentication_tokens()
    request.session['request_token'] = auth_props
    return HttpResponseRedirect(auth_props['auth_url'])


def twitter_callback(request, redirect_url=settings.LOGIN_REDIRECT_URL):
    twitter = Twython(
        twitter_token = settings.TWITTER_KEY,
        twitter_secret = settings.TWITTER_SECRET,
        oauth_token = request.session['request_token']['oauth_token'],
        oauth_token_secret = request.session['request_token']['oauth_token_secret'],
    )

    authorized_tokens = twitter.get_authorized_tokens()

    try:
        profile = TwitterProfile.objects.get(screen_name = authorized_tokens['screen_name'])
        user = User.objects.get(pk=profile.user_id)
        user.backend = 'django.contrib.auth.backends.ModelBackend'

        if user.is_active:
            auth_login(request, user)
            return HttpResponseRedirect(reverse('app_name:url_name'))
        else:
            //failed back to login
            return HttpResponseRedirect(reverse('app_name:login'))
    except TwitterProfile.DoesNotExist:
        screen_name = authorized_tokens['screen_name']
        oauth_token = authorized_tokens['oauth_token']
        oauth_token_secret = authorized_tokens['oauth_token_secret']

        //create new twitter profile
        //create new user here
        //authenticate the new register user then login
        .........

模板

<a href="{% url social:twitter_login %}">Twitter</a>
