webapp2

问题 I am using GAE for an app that has various submit href buttons, and use javascript to submit. I am having a real tough time trying to figure out how to prevent multiple submits or doubl-clicking. I have tried various methods to disable or remove the href with javascript. But I am thinking if there is maybe a method to prevent this in the backend.

问题 I am trying to run HealthChecks UI AspNetCore.Diagnostics.HealthChecks in my ASP.NET Core WebAPI. All works fine on local, but when I deploy to Azure WebApp whole application dies.

问题 I'm trying to get Appstats to work on my GAE Python app. I'm using webapp2 with python 2.7. I've followed the instructions from https://developers.google.com/appengine/docs/python/tools/appstats#Setup which includes creating the appengine_config.py file: def webapp_add_wsgi_middleware(app): from google.appengine.ext.appstats import recording app = recording.appstats_wsgi_middleware(app) return app And adding the following lines to my app.yaml: builtins: - appstats: on The python app I wish to

问题 I have a Python App Engine application which serves about 3M requests per day. I am trying to optimize the app to save on my ridiculously ballooned hosting bill. November, App Engine Frontend Instances: 12924.391 Hours, $604.22 I have the request handling down to some memcached calls, but now I've noticed that it usually takes about 20ms, sometimes as long as 166ms before webapp2 even passes the request to me. In the image below you can see a Trace showing "Post" happening at 166ms. Here is

问题 I'm trying to run a python file on a subdomain that I created. According to HostGator, python files are supported, but not the webapp2 framework, which I used throughout the file: #!/usr/bin/env python # # Copyright 2007 Google Inc. # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # You may obtain a copy of the License at # # http://www.apache.org/licenses/LICENSE-2.0 # # Unless required by applicable law or

问题 I am learning the webapp2 framework with its powerful Route mechanism. My application is supposed to accept URIs like these: /poll/abc-123 /poll/abc-123/ /poll/abc-123/vote/ # post new vote /poll/abc-123/vote/456 # view/update a vote Polls may optionally be organized into categories, so all the above should work also like this: /mycategory/poll/abc-123 /mycategory/poll/abc-123/ /mycategory/poll/abc-123/vote/ /mycategory/poll/abc-123/vote/456 My incorrect configuration: app = webapp2
