示例代码

def fetch(ip):
    url = 'http://ip.taobao.com/service/getIpInfo.php?ip=' + ip
    result = []    try:
        response = urllib.urlopen(url).read()

            result.append(jsondata[u'data'][u'ip'].encode('utf-8'))            
            result.append(jsondata[u'data'][u'country'].encode('utf-8'))
            result.append(jsondata[u'data'][u'country_id'].encode('utf-8'))
            result.append(jsondata[u'data'][u'area'].encode('utf-8'))
            result.append(jsondata[u'data'][u'area_id'].encode('utf-8'))
            result.append(jsondata[u'data'][u'region'].encode('utf-8'))
            result.append(jsondata[u'data'][u'region_id'].encode('utf-8'))
            result.append(jsondata[u'data'][u'city'].encode('utf-8'))

            result.append(jsondata[u'data'][u'isp'].encode('utf-8'))
            result.append(jsondata[u'data'][u'isp_id'].encode('utf-8'))            
        else:            return 0, result    except:

            ok, result = fetch(ip)            if not ok:
                logging.error("Fetch information failed, ip:{}".format(ip))

def progproc(progressbar, count, progress):    """
    Since ProgressBar is not a thread-safe class, we use a Queue to do the counting job, like
    two other threads. Use this thread do the printing of progress bar. By the way, it will

    idx = 1    while True:        try:
