python的框架1-swgi使用

内置web服务器例子：

from wsgiref.simple_server import make_server
def f1():
    return [b'<h1>book</h1>']
def f2():
    return [b'<h1>test</h1>']
def f3():
    return [b'<h1>404</h1>']

def routers():
    urls = (
        ('/book',f1),
        ('/test',f2),
    )
    return urls
def application(environ,start_response):
    path_info = environ["PATH_INFO"]
    start_response('200 OK', [('Content-Type', 'text/html')])
    func = None
    urlInfo = routers()
    for i in urlInfo:
        if i[0]==path_info:
            func = i[1]
            break
    if func:
        return func()
    else:
        return f3()

httpd = make_server('',8080,application)
print("serving http on port 8080")
httpd.serve_forever()
