Oauth2使用Python 3.4和Django 1.7

我尝试使用oauth2授权我的django应用程序,以便与google内容进行购物API交互。但是,我在此过程中遇到了oauth2的问题。

我安装了oauth2client和google-api-python-client。我的观点如下:

CLIENT_SECRETS = os.path.join(os.path.dirname(__file__), 'client_secret.json')

FLOW = flow_from_clientsecrets(
    CLIENT_SECRETS,
    scope='https://www.googleapis.com/auth/content',
    redirect_uri='https://127.0.0.1:8000/oauth2/oauth2callback')


def get_account_ids(service):
    accounts = service.management().accounts().list().execute()
    ids = []
    if accounts.get('items'):
        for account in accounts['items']:
            ids.append(account['id'])
    return ids


@login_required
def index(request):
    user = request.user
    storage = Storage(CredentialsModel, 'id', user, 'credential')
    credential = storage.get()    
    if credential is None:
        FLOW.params['state'] = xsrfutil.generate_token(
            settings.SECRET_KEY, user)
        authorize_url = FLOW.step1_get_authorize_url()
        f = FlowModel(id=user, flow=FLOW)
        f.save()
        return HttpResponseRedirect(authorize_url)
    else:
        http = httplib2.Http()
        http = credential.authorize(http)
        service = build('content', 'v2', http=http)
        ids = get_account_ids(service)
        return render(
            request, 'index.html', {'ids':ids})


@login_required
def auth_return(request):
    user = request.user
    if not xsrfutil.validate_token(settings.SECRET_KEY, bytes(request.GET['state'], 'utf-8'), user):
        return HttpResponseBadRequest()
    credential = FLOW.step2_exchange(request.GET, http=None)
    storage = Storage(CredentialsModel, 'id', user, 'credential')
    storage.put(credential)
    return HttpResponseRedirect("/oauth2/")

首先,我从auth_return视图收到错误, request.GET [&#39; state&#39;] 重新调整后的字符串没有编码,所以我改变了这个:< / p>

if not xsrfutil.validate_token(settings.SECRET_KEY, request.GET['state'], user):

到此:

if not xsrfutil.validate_token(settings.SECRET_KEY, bytes(request.GET['state'], 'utf-8'), user):
        return HttpResponseBadRequest()

错误消失了。但是,我现在收到错误:

'bytes' object has no attribute 'authorize'

从索引视图。导致异常的确切行是:

http = credential.authorize(http)

这似乎是由我早先的改变造成的。我是使用oauth2的新手,我已经花了很多时间尝试调试。有谁能指出我正确的方向?

提前谢谢。

我终于找到了答案。

似乎oauth2client中的django_orm模块使用&#39; to_python&#39; CredentialsField定义中的函数,它不起作用,因此返回Base64数据。

要解决此问题,您必须从以下位置编辑oauth2client / django_orm源定义:

Request.createWizard(req.user, { productId: productId }, function(err, request) {
  Product.findById(productId, function(err, product) {
    if (err) {
        return console.log('oh no! error', err);
    } else {
      if (product.price !== 0) {
        request.status = 'ready';
        request.save(function(err) { // <-- save it back to the database
          if (err) {
            console.log('oh no! error', err);
          } else {
            console.log(request);
          }
        });
      }
    }  
  });
  req.flash('success', { msg: 'Your request has been successfully created.' });
  res.redirect('/discover');
});

为:

class CredentialsField(models.Field):

这将允许它返回Python2和Python3的Credentials对象。

确保首先删除当前存储的凭证对象,因为它是字符串对象而不是凭据对象。
