Google AppEngine WebApp2上的PATCH方法处理程序 [英] PATCH method handler on Google AppEngine WebApp2

问题描述

我尝试在 webapp2.RequestHandler 中使用 def patch（）：方法来支持部分资源更新，但后来发现允许的方法在webapp2.py中被冻结：

  allowed_methods = frozenset（（'GET'，'POST '''HEAD'''OPTIONS''PUT'
'DELETE'TRACE'））
 b $ b 
如何扩展 webapp2.RequestHandler 或修改 WSGIApplication 类以允许PATCH HTTP方法当部署在Google AppEngine上时？
解决方案
在创建 WSGIApplication ：
 
 $ pre $允许_方法= PATCH'，））
 webapp2.WSGIApplication.allowed_methods = new_allowed_methods 
  

当前有一个< a href =h ttps：//code.google.com/p/webapp-improved/issues/detail？id = 69>补丁在 webapp2 问题跟踪器上，但不支持一个已经拿起它。

I tried to use a def patch(): method in my webapp2.RequestHandler to support partial resource updates, but then saw that the allowed methods are frozen in webapp2.py:

allowed_methods = frozenset(('GET', 'POST', 'HEAD', 'OPTIONS', 'PUT',
                             'DELETE', 'TRACE'))

How can I extend webapp2.RequestHandler or modify the WSGIApplication class to allow the PATCH HTTP method when deployed on Google AppEngine?

解决方案

Just use a monkey patch by performing this before creating a WSGIApplication:

allowed_methods = webapp2.WSGIApplication.allowed_methods
new_allowed_methods = allowed_methods.union(('PATCH',))
webapp2.WSGIApplication.allowed_methods = new_allowed_methods

There is a current patch on the webapp2 issue tracker but no one has picked it up.
