我正在尝试订阅标签。hub.challenge
似乎使用and正确调用了回调 URL hub.mode
,我想出了如何使用self.request.get('hub.challenge')
. 我以为我只是应该回应挑战,但这似乎不起作用,因为我在 GAE 日志中收到以下错误:
InstagramAPIError: (400) APISubscriptionError-Challenge verification failed. Sent "647bf6dbed31465093ee970577ce1b72", received "
647bf6dbed31465093ee970577ce1b72
".
这是完整的处理程序:
class InstagramHandler(BaseHandler):
def get(self):
def process_tag_update(update):
update = update
mode = self.request.get('hub.mode')
challenge = self.request.get('hub.challenge')
verify_token = self.request.get('hub.verify_token')
if challenge:
template_values = {'challenge':challenge}
path = os.path.join(os.path.dirname(__file__), '../templates/instagram.html')
html = template.render(path, template_values)
self.response.out.write(html)
else:
reactor = subscriptions.SubscriptionsReactor()
reactor.register_callback(subscriptions.SubscriptionType.TAG, process_tag_update)
x_hub_signature = self.request.headers.get('X-Hub-Signature')
raw_response = self.request.data
try:
reactor.process('INSTAGRAM_SECRET', raw_response, x_hub_signature)
except subscriptions.SubscriptionVerifyError:
logging.error('Instagram signature mismatch')
