如何在cherrypy中添加重试标头？

  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())

这个重试头 dt 有效。

How can I add retry-header in cherrypy?

  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())

This retry-header dt works.

当您通过引发 HTTPError 设置状态代码时，cherrypy.response.headers 中的标头将被忽略。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())

When you set a status code by raising HTTPError, the headers in cherrypy.response.headers are ignored. Set the HTTP status by setting cherrypy.response.status instead:

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())
