python3 通过 pycurl 检测

由于python3 对StringIO 集成到io 模块中了，所有python3 import StringIO 改成了 import io，pycurl.Curl() 初始化对象C ，其 属性WRITEFUNCTION 要求传递参数是byte，b.write 需要初始化成io.BytesIO()

#!/bin/env pyhon3 import pycurl import io

def check(urls): dict_data={} #if url not in errorurl: url = 'http://' + str(urls) dict_data['url']=url c = pycurl.Curl() c.setopt(pycurl.CONNECTTIMEOUT,5) c.setopt(pycurl.TIMEOUT,5) c.setopt(pycurl.NOPROGRESS,1) c.setopt(pycurl.FORBID_REUSE,1) c.setopt(pycurl.MAXREDIRS,3) c.setopt(pycurl.DNS_CACHE_TIMEOUT,30) c.setopt(c.URL, url) try: b = io.BytesIO() c.setopt(c.WRITEFUNCTION, b.write) c.perform() HTTP_CODE = c.getinfo(pycurl.HTTP_CODE) #HTTP状态码 dict_data['HTTP状态码'] = HTTP_CODE DNS_TIME = c.getinfo(c.NAMELOOKUP_TIME) 1000 #DNS消耗时间 dict_data['DNS消耗时间'] = DNS_TIME CONNECT_TIME = c.getinfo(c.CONNECT_TIME) 1000 #建连消耗时间 dict_data['建连消耗时间'] = CONNECT_TIME PRETRANSFER_TIME = c.getinfo(c.PRETRANSFER_TIME) 1000 #建连到准备传输消耗 dict_data['建连到准备传输消耗'] = PRETRANSFER_TIME STARTTRANSFER_TIME = c.getinfo(c.STARTTRANSFER_TIME) 1000 #建连到传输消耗 dict_data['建连到传输消耗'] = STARTTRANSFER_TIME TOTAL_TIME = c.getinfo(c.TOTAL_TIME) * 1000 #传输结束消耗时间 dict_data['传输结束消耗时间'] = TOTAL_TIME SPEED_DOWNLOAD = c.getinfo(c.SPEED_DOWNLOAD) #平均下载速度 dict_data['平均下载速度'] = SPEED_DOWNLOAD b.close() c.close() except pycurl.error: pass #errno, errstr = error #print 'An error occurred: ', errstr for var in dict_data.keys(): print(var,':',dict_data[var]) website=input('请输入检测站点域名:如www.baidu.com') check(website)
