重构实例1：最初的测试代码

最初的测试代码还是比较能清晰的反映出代码的意图

文件: code.py

启动: python code.py

查看:

http://127.0.0.1:8080/app1?id=100

import web

urls = (
    '/app1', 'App1',
    '/app2', 'App2',
)

web.config.debug = False
app = web.application(urls, globals())

class PageBase:
    def __init__(self):
        self.funGET = self.GET
        self.GET = self.get

    def get(self):
        wi = web.input()
        if hasattr(wi,"id"):
            self.s = wi.id
        else:
            self.s = "hello"
        return self.funGET()

class App1(PageBase):
    def GET(self):
        return self.s

class App2(PageBase):
    def GET(self):
        return self.s

if __name__ == "__main__":
    app.run()
