# 用WSGI应用形式编写的简单HTTP服务。
#!/usr/bin/env python3 
# A simple HTTP service built directly against the low-level WSGI spec. 
from pprint import pformat 
from wsgiref.simple_server import make_server 
def app(environ, start_response): 
 headers = {'Content-Type': 'text/plain; charset=utf-8'} 
 start_response('200 OK', list(headers.items())) 
 yield 'Here is the WSGI environment: 
'.encode('utf-8') 
 yield pformat(environ).encode('utf-8') 
if __name__ == '__main__': 
 httpd = make_server('', 8000, app) 
 host, port = httpd.socket.getsockname() 
 print('Serving on', host, 'port', port) 
 httpd.serve_forever()

#!/usr/bin/env python3 
# A simple HTTP service built directly against the low-level WSGI spec. 
import time 
def app(environ, start_response): 
  host = environ.get('HTTP_HOST', '127.0.0.1') 
  path = environ.get('PATH_INFO', '/') 
  if ':' in host: 
    host, port = host.split(':', 1) 
  if '"htmlcode">

#!/usr/bin/env python3 
# A WSGI callable built using webob. 
import time, webob 
def app(environ, start_response): 
  request = webob.Request(environ) 
  if environ['REQUEST_METHOD'] != 'GET': 
    response = webob.Response('501 Not Implemented', status=501) 
  elif request.domain != '127.0.0.1' or request.path != '/': 
    response = webob.Response('404 Not Found', status=404) 
  else: 
    response = webob.Response(time.ctime()) 
  return response(environ, start_response)




第二个是使用Werkzeug编写的WSGI可调用对象返回当前时间。



#!/usr/bin/env python3 
# A WSGI callable built using Werkzeug. 
import time 
from werkzeug.wrappers import Request, Response 
@Request.application 
def app(request): 
  host = request.host 
  if ':' in host: 
    host, port = host.split(':', 1) 
  if request.method != 'GET': 
    return Response('501 Not Implemented', status=501) 
  elif host != '127.0.0.1' or request.path != '/': 
    return Response('404 Not Found', status=404) 
  else: 
    return Response(time.ctime())




大家可以对比这两个库在简化操作时的不同之处，Werkzeug是Flask框架的基础。
