自定义NotFound消息

问题

如何定义NotFound消息和其他消息？

解法

import web
urls = (...)
app =  web.application(urls, globals())
def notfound():
    return web.notfound("Sorry, the page you were looking for was not found.")
    # You can use template result like below, either is ok:
    #return web.notfound(render.notfound())
    #return web.notfound(str(render.notfound()))
app.notfound = notfound

要返回自定义的NotFound消息，这么做即可：

class example:
    def GET(self):
        raise web.notfound()

也可以用同样的方法自定义500错误消息：

def internalerror():
    return web.internalerror("Bad, bad server. No donut for you.")
app.internalerror = internalerror
