python3测试网站网速

一、运行环境

1、Windows 10

2、python 3.8

二、安装第三方库pycurl

1、先安装

pip install wheel

2、在安装pycurl

https://download.lfd.uci.edu/pythonlibs/t7epjj8p/pycurl-7.43.0.3-cp38-cp38-win_amd64.whl

三、测试脚本

 import pycurl
 import os,sys
 import time
 import sys

 try:
     URL=sys.argv[1]    # 测试网站的域名
 except Exception as e:
     print ("Error:"+str(e))
     print ("用法：请输入要探测的web地址")
     sys.exit()
 #URL="http://www.baidu.com"    #测试网站的域名
 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()    #提交请求
 except Exception as e:
     print("connecion 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("测试网站:",URL)
 print("HTTP状态码:{}" .format(HTTP_CODE))
 print("HTTP状态码：%s" %(HTTP_CODE))
 print("DNS解析时间：%.2f ms"%(NAMELOOKUP_TIME*1000))
 print("建立连接时间：%.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))
 #关闭文件及Curl对象
 indexfile.close()
 c.close()

四、验证
