python验证代理IP

接上一篇保存的IP地址，进行验证

#利用多线程，在新浪IP接口上，验证IP
def verify_ip():

        lock.acquire()
        ip = get_ip.readline().strip()
        #解开锁
        lock.release()

        proxies = {\'http\': ip}

        r = requests.get(url, headers=headers, proxies=proxies,timeout=5)

        print ip

    except:

    t = Thread(target=verify_ip)
    thread_all.append(t)
    t.start()

for t in thread_all:
    t.join()

get_ip.close()
