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。
