代理ip的使用

代理ip的使用：

    ip_list1 = [代理ip。。。]
    def agency():
    
        f= open('daili.txt','r')
        for a in f:
            a = a.strip('\n')
    
            ip_list1.append(a)
            print(a)
        print(ip_list1)
    
        for i in ip_list1:
            item = i
            print(item)
    
            proxyHost = item
            proxyPort = "3128"
    
            proxyMeta = 'http://'+proxyHost+':'+proxyPort
            print(proxyMeta)
            proxies = {
                "http": proxyMeta,
                "https": proxyMeta,
            }
            print(proxies)
            # 如果连接成功，且返回来内容认为ip可用，返回该ip退出循环
            try:
                rsp = requests.get("http://www.baidu.com", proxies=proxies)
                print(rsp.text)
                print('可用')
            except :
                print('不可用')
                ip_list1.remove(item)
            # time.sleep(3)
