今天跟大家分享的是 运用pyhon语言 进行循环指定CDN节点进行url测试，说白了就是 用curl 或者 wget 加url指定 节点测试 看返回的状态码，代码如下:

#!/usr/bin/env python
#-*- coding:utf-8 -*-
import re
import os
import sys
import socket
import requests
class Testurl(object):

    def __init__(self,proxy,url):
        self.proxy   = proxy
        self.url     = url
        self.proxies = {}
        self.repeat  =  []

    def FilterNode(self):
        while True:
            nodeip   = socket.gethostbyname(self.proxy)
            self.repeat.append(nodeip)
            if self.repeat.count(nodeip) == 1:
                pass
            else:
                break

    def StartTest(self):
        for x in self.repeat:
            try:

                status = re.search('[+[0-9]+]',str(result))
            except Exception as e:
