Webob

Webob USGI 装饰器

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)    
httpd.serve_forever()

如何是本机访问，则输出’hi‘，否则不允许。
