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

 1 import pycurl
 2 import os,sys
 3 import time
 4 import sys
 5 
 6 
 7 try:
 8     URL=sys.argv[1]    # 测试网站的域名
 9 except Exception as e:
10     print ("Error:"+str(e))
11     print ("用法：请输入要探测的web地址")
12     sys.exit()
13 #URL="http://www.baidu.com"    #测试网站的域名
14 c = pycurl.Curl()    
15 c.setopt(pycurl.URL, URL)    
16 c.setopt(pycurl.CONNECTTIMEOUT, 5)    
17 c.setopt(pycurl.TIMEOUT, 5)    
18 c.setopt(pycurl.NOPROGRESS, 1)    
19 c.setopt(pycurl.FORBID_REUSE, 1)    
20 c.setopt(pycurl.MAXREDIRS, 1)

24 c.setopt(pycurl.WRITEHEADER, indexfile)    
25 c.setopt(pycurl.WRITEDATA, indexfile)   
26 try:
27     c.perform()    #提交请求
28 except Exception as e:
29     print("connecion error:"+str(e))
30     indexfile.close()
31     c.close()
32     sys.exit()
33 
34 NAMELOOKUP_TIME =  c.getinfo(c.NAMELOOKUP_TIME)

38

44 
45 print("测试网站:",URL)
46 print("HTTP状态码:{}" .format(HTTP_CODE))
47 print("HTTP状态码：%s" %(HTTP_CODE))
48 print("DNS解析时间：%.2f ms"%(NAMELOOKUP_TIME*1000))
49 print("建立连接时间：%.2f ms" %(CONNECT_TIME*1000))
50 print("准备传输时间：%.2f ms" %(PRETRANSFER_TIME*1000))
51 print("传输开始时间：%.2f ms" %(STARTTRANSFER_TIME*1000))
52 print("传输结束总时间：%.2f ms" %(TOTAL_TIME*1000))
53 print("下载数据包大小：%d bytes/s" %(SIZE_DOWNLOAD))
54 print("HTTP头部大小：%d byte" %(HEADER_SIZE))
55 print("平均下载速度：%d bytes/s" %(SPEED_DOWNLOAD))
56 #关闭文件及Curl对象
57 indexfile.close()
58 c.close()
