【问题描述】：
我正在使用带有 Allauth + REST-Auth 的 Django 进行 SPA 社交登录，并成功设置了 Facebook、VK 和 Google 授权，但在添加 Twitter 时遇到了问题。它以 {"code":89,"message":"Invalid or expired token."} 结尾。 看起来我错过了一些“使用 Twitter 进行标准登录”的功能
这是我的尝试：
首先，我已经按照文档中的描述设置了 Twitter 登录端点：
class TwitterLogin(SocialLoginView):
serializer_class = TwitterLoginSerializer
adapter_class = CustomTwitterOAuthAdapter
它具有 post 方法，期望 access_token 和 token_secret 因此创建了重定向视图以接收来自 twitter 的重定向，完成登录并通过模板渲染将内部 django 令牌设置为浏览器 localStorage（带有几行 JS 行）：
class TwitterReceiveView(APIView):
def get(self, request, *args, **kwargs):
access_token = request.query_params.get('oauth_token')
token_secret = request.query_params.get('oauth_verifier')
params = {'access_token': access_token,
'token_secret': token_secret}
try:
result = requests.post(settings.DOMAIN + reverse('tw_login'), data=params).text
result = json.loads(result)
except (requests.HTTPError, json.decoder.JSONDecodeError):
result = {}
access_token = result.get('access_token')
context = {'access_token': access_token}
return render(request, 'account/local_storage_setter.html',
context, content_type='text/html')
不得不提的是，我尝试了两种方法来启动进程（获取初始令牌） 1.使用标准allauth urlhttp://0.0.0.0:8080/accounts/twitter/login 2. 创建了另一个可以从 SPA 使用的视图（使用 lib python oauth2）：
class TwitterGetToken(APIView):
def get(self, request, *args, **kwargs):
request_token_url = 'https://api.twitter.com/oauth/request_token'
authorize_url = 'https://api.twitter.com/oauth/authorize'
app = SocialApp.objects.filter(name='Twitter').first()
if app and app.client_id and app.secret:
consumer = oauth.Consumer(app.client_id, app.secret)
client = oauth.Client(consumer)
resp, content = client.request(request_token_url, "GET")
if resp['status'] != '200':
raise Exception("Invalid response {}".format(resp['status']))
request_token = dict(urllib.parse.parse_qsl(content.decode("utf-8")))
twitter_authorize_url = "{0}?oauth_token={1}"\
.format(authorize_url, request_token['oauth_token'])
return redirect(twitter_authorize_url)
raise Exception("Twitter app is not set up")
我什至尝试为 FacebookLoginView 编写 get 方法并直接将 twitter 回调传递给它
class TwitterLogin(SocialLoginView):
serializer_class = TwitterLoginSerializer
adapter_class = TwitterOAuthAdapter
def get(self, request, *args, **kwargs):
data = {
'access_token': request.query_params.get('oauth_token'),
'token_secret': request.query_params.get('oauth_verifier')
}
self.request = request
self.serializer = self.get_serializer(data=data,
context={'request': request})
self.serializer.is_valid(raise_exception=True)
self.login()
return self.get_response()
所有方法都导致我提到了错误。请您就我的情况提出一些建议。提前谢谢！
