python cherrypy - 如何添加标题

Question

如何在cherrypy中添加重试标题？

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retry-header dt起作用。

当您通过提高HTTPError来设置状态代码时，cherrypy.response.headers中的标题将被忽略。通过设置cherrypy.response.status，而不是设置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())
