不知为何,也许我对pycurl模块了解不够透彻的原因吧,测出来的时间与firebug所得不同,但是firebug是对的,这点我肯定
仍将学习到的代码贴出如下
#!/usr/local/bin/python3.5 # -*- coding: utf-8 -*- import pycurl import time import os import sys URL = "http://xxx.xxxx.xxx.xx" c = pycurl.Curl() c.setopt(pycurl.URL, URL) 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, 1) c.setopt(pycurl.DNS_CACHE_TIMEOUT, 30) indexfile = open(os.path.dirname(os.path.realpath(__file__)) + "/content.txt", "wb") c.setopt(pycurl.WRITEHEADER, indexfile) c.setopt(pycurl.WRITEDATA, indexfile) try: c.perform() except Exception as e: print("connection error :" + str(e)) indexfile.close() c.close() sys.exit() NAMELOOKUP_TIME = c.getinfo(c.NAMELOOKUP_TIME) CONNECT_TIME = c.getinfo(c.CONNECT_TIME) PRETRANSFER_TIME = c.getinfo(c.PRETRANSFER_TIME) STARTTRANSFER_TIME = c.getinfo(c.STARTTRANSFER_TIME) TOTAL_TIME = c.getinfo(c.TOTAL_TIME) HTTP_CODE = c.getinfo(c.HTTP_CODE) SIZE_DOWNLOAD = c.getinfo(c.SIZE_DOWNLOAD) HEADER_SIZE = c.getinfo(c.HEADER_SIZE) SPEED_DOWNLOAD = c.getinfo(c.SPEED_DOWNLOAD) print("HTTP状态码:%s" % (HTTP_CODE)) print("DNS解析时间:%.2f ms" % (NAMELOOKUP_TIME*1000)) print("建立链接时间:%.2f ms" % (CONNECT_TIME*1000)) print("准备传输时间:%.2f ms" % (PRETRANSFER_TIME*1000)) print("传输开始时间:%.2f ms" % (STARTTRANSFER_TIME*1000)) print("传输结束总时间:%.2f ms" % (TOTAL_TIME*1000)) print("下载数据包大小:%d bytes/s" % (SIZE_DOWNLOAD)) print("HTTP头部大小:%d byte" % (HEADER_SIZE)) print("平均下载速度:%d bytes/s" % (SPEED_DOWNLOAD)) indexfile.close() c.close()
测的结果
END!
