web.py+pexpect

今天没事倒到了python的web.py的web框架，好简单。。。顺便用了下pexpect,加起来不到30行代码，美女时钟，哈哈

import random

import sys
sys.path.append("/home/youdata/python/lib/lib/python2.7/site-packages/")
import web
import pexpect

urls = (
    '/(.*)', 'default',
)
class default:
    def GET(self, name):
        if not name:
            name = "world"
        data = "curl \"http://www.sodao.com/\" 2>/dev/null | grep \"http://imgcache.mysodao.com\"| grep \'width=\"600\"\'"
        child = pexpect.spawn('/bin/bash', ['-c', data], timeout=10, maxread=1024*1024)
        index = child.expect([pexpect.EOF, pexpect.TIMEOUT])
        if index != 0 :
            return str(name) + "\n time out"

        imgs = child.before.split("\n")
        index = random.randint(0, len(imgs) - 2)
        return "" + imgs[index] + ""

if __name__ == "__main__":
    app = web.application(urls, globals())
    app.run()
