python cherrypy-如何添加头

Question

如何在cherrypy中添加重试头？

  import cherrypy
  import os

  class Root:

    def index(self):
      cherrypy.response.headers['Retry-After'] = 60
      cherrypy.request.headers["Age"]= 20
      cherrypy.config.update({'Retry-After': '60'})

      raise cherrypy.HTTPError(503, 'Service Unavailable')
    index.exposed = True 

    cherrypy.quickstart(Root())

此重试头dt有效。

通过提升HTTPError设置状态代码时，将忽略cherrypy.response.headers中的头。通过设置cherrypy.response.status来设置HTTP状态：

import cherrypy

class Root:
    def index(self):
        cherrypy.response.headers['Retry-After'] = 60
        cherrypy.response.status = 503
        # Feel free to return a better error page than the following
        return "<h1>Service Unavailable</h1>"
    index.exposed = True

cherrypy.quickstart(Root())
