wsgify装饰器将一个普通函数转变成WSGI应用程序。
class webob.dec.wsgify(func=None, RequestClass=None, args=(), kwargs=None, middleware_wraps=None)
from wsgiref.simple_server import make_server
from webob import Request, Response
from webob.dec import *
@wsgify
def test(req):
res = Response()
res.status = 200
res.body = "spch"
return res
class MyApp:
def __call__(self, environ, start_response):
req = Request(environ)
return test(environ, start_response)
application = MyApp()
httpd = make_server('localhost', 8081, application)
httpd.serve_forever()
其中，参数req为一个Request实例，可以通过req读取相应环境变量。
而且，我们可以定制装饰器
from wsgiref.simple_server import make_server
from webob import Request, Response
from webob.dec import *
from webob.exc import *
class MyRequest(Request):
@property
def is_local(self):
return self.remote_addr == '127.0.0.1'
@wsgify(RequestClass=MyRequest)
def myfunc(req):
if req.is_local:
return Response('hi!')
else:
raise HTTPForbidden
class MyApp:
def __call__(self, environ, start_response):
req = Request(environ)
return myfunc(environ, start_response)
application = MyApp()
httpd = make_server('localhost', 8081, application)
如何是本机访问，则输出’hi‘，否则不允许
