체리 서버 이름 태그

Question

Cherrypy 앱을 실행하면 Cherrypy/버전과 같은 서버 이름 태그를 보냅니다. Cherrypy를 수정하지 않고 앱에서 이름을 바꿀 수 있으므로 다른 것을 보여줄 수 있습니까?

아마도 myAppName/버전 (Cherrypy/버전)과 같은 것일 수 있습니다.

Answer 1

Actually asking on IRC on their official channel fumanchu gived me a more clean way to do this (using latest svn):

import cherrypy
from cherrypy import _cpwsgi_server 
class HelloWorld(object):
    def index(self):
        return "Hello World!"
    index.exposed = True

serverTag = "MyApp/%s (CherryPy/%s)" % ("1.2.3", cherrypy.__version__)
_cpwsgi_server.CPWSGIServer.environ['SERVER_SOFTWARE'] = serverTag
cherrypy.config.update({'tools.response_headers.on': True,
                        'tools.response_headers.headers': [('Server', serverTag)]})
cherrypy.quickstart(HelloWorld())

Answer 2

This can now be set on a per application basis in the config file/dict

[/]  
response.headers.server = "CherryPy Dev01"

Answer 3

This string appears to be being set in the CherrPy Response class:

def __init__(self):
  self.status = None
  self.header_list = None
  self._body = []
  self.time = time.time()

  self.headers = http.HeaderMap()
  # Since we know all our keys are titled strings, we can
  # bypass HeaderMap.update and get a big speed boost.
  dict.update(self.headers, {
    "Content-Type": 'text/html',
    "Server": "CherryPy/" + cherrypy.__version__,
    "Date": http.HTTPDate(self.time),
  })

So when you're creating your Response object, you can update the "Server" header to display your desired string. From the CherrPy Response Object documentation:

headers

A dictionary containing the headers of the response. You may set values in this dict anytime before the finalize phase, after which CherryPy switches to using header_list ...

EDIT: To avoid needing to make this change with every response object you create, one simple way to get around this is to wrap the Response object. For example, you can create your own Response object that inherits from CherryPy's Response and updates the headers key after initializing:

class MyResponse(Response):

    def __init__(self):
        Response.__init__(self)
        dict.update(self.headers, {
            "Server": "MyServer/1.0",
        })

RespObject = MyResponse()
print RespObject.headers["Server"]

Then you can can call your object for uses where you need to create a Response object, and it will always have the Server header set to your desired string.
