GAE:检查我是否在dev_appserver上或已部署到appspot的python代码 [英] GAE: python code to check if i'm on dev_appserver or deployed to appspot

问题描述

我的GAE应用程序使用OAUTH2.目前，我是根据是使用dev_appserver进行本地测试还是将其部署到appspot.com，在http://localhost:8081/oauth2callback和myapp.appspot.com/oauth2callback之间手动切换redirect_uri.

My GAE app uses OAUTH 2. Currently, I manually switch the redirect_uri between http://localhost:8081/oauth2callback and myapp.appspot.com/oauth2callback depending on whether do local testing with dev_appserver or if I deploy to appspot.com.

是否可以使用一些代码(例如，使用os.environ)来自动执行此操作?

Is there some code (e.g. using os.environ) that I can use to automate this?

谢谢！

推荐答案

您可以通过os.environ['SERVER_NAME']获取当前域名.

You can get you current domain name with os.environ['SERVER_NAME'].

您还可以按版本名称进行检查:

You also can check this by version name:

import os
if os.environ['APPLICATION_ID'].startswith('dev'):
  pass  # it's localhost
else:
  pass  # it's uploaded on gae

如果使用webapp2，最好使用self.uri_for('callback-uri-name', _full=True)构建回调uri.

Will be better to use self.uri_for('callback-uri-name', _full=True) for building callback uri if you use webapp2.

您的路线中有类似的东西.

You have something like this in your routes.

app = webapp2.WSGIApplication([
    webapp2.Route(r'/oauth/callback', handler='oauth.CallbackHandler', name='callback-uri-name'),
])

然后，如果您拨打self.uri_for('callback-uri-name', _full=True)，您会得到类似http://localhost:8080/oauth/callback或http://app-id.appspot.com/oauth/callback的信息.

Then, if you'll call self.uri_for('callback-uri-name', _full=True) you'll get something like http://localhost:8080/oauth/callback or http://app-id.appspot.com/oauth/callback.
