WebOb
WebOb是一个用于对WSGI request环境进行包装，以及用于创建WSGI response的一个包。
Related API Link: http://docs.webob.org/en/latest/reference.html
WebOb把WSGI的几个参数、返回的方法都封装成了Reqeust、Response这两个对象，同时还提供了一个好用的Exception对象，使用方便。
WSGI Server -> (WSGI Middleware)* -> WSGI Application
from wsgiref.simple_server import make_server URL_PATTERNS= ( (‘hi/‘,‘say_hi‘), (‘hello/‘,‘say_hello‘), ) class Dispatcher(object): def _match(self,path): path = path.split(‘/‘)[1] for url,app in URL_PATTERNS: if path in url: return app def __call__(self,environ, start_response): path = environ.get(‘PATH_INFO‘,‘/‘) app = self._match(path) if app : app = globals()[app] return app(environ, start_response) else: start_response("404 NOT FOUND",[(‘Content-type‘, ‘text/plain‘)]) return ["Page dose not exists!"] def say_hi(environ, start_response): start_response("200 OK",[(‘Content-type‘, ‘text/html‘)]) return ["kenshin say hi to you!"] def say_hello(environ, start_response): start_response("200 OK",[(‘Content-type‘, ‘text/html‘)]) return ["kenshin say hello to you!"] app = Dispatcher() httpd = make_server(‘‘, 8000, app) print "Serving on port 8000..." httpd.serve_forever()
1.Request
# application/x-www-form-urlencoded：窗体数据被编码为名称/值对。这是标准的编码格式。
# multipart/form-data：窗体数据被编码为一条消息，页上的每个控件对应消息中的一个部分。
# text/plain：窗体数据以纯文本形式进行编码，其中不含任何控件或格式字符
2.Response
3.Exception
下述总结了WebOb对于HTTP返回码的类定义。
