python3測試網站網速

一、運行環境

1、Windows 10

2、python 3.8

二、安裝第三方庫pycurl

1、先安裝

pip install wheel

2、在安裝pycurl

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

三、測試腳本

import pycurl
import os,sys
import time
import sys


try:
    URL=sys.argv[1]    # 測試網站的域名
except Exception as e:
    print ("Error:"+str(e))
    print ("用法：請輸入要探測的web地址")
    sys.exit()
#URL="http://www.baidu.com"    #測試網站的域名
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()    #提交請求
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("測試網站:",URL)
print("HTTP狀態碼:{}" .format(HTTP_CODE))
print("HTTP狀態碼：%s" %(HTTP_CODE))
print("DNS解析時間：%.2f ms"%(NAMELOOKUP_TIME*1000))
print("建立連接時間：%.2f ms" %(CONNECT_TIME*1000))
print("准備傳輸時間：%.2f ms" %(PRETRANSFER_TIME*1000))
print("傳輸開始時間：%.2f ms" %(STARTTRANSFER_TIME*1000))
print("傳輸結束總時間：%.2f ms" %(TOTAL_TIME*1000))
print("下載數據包大小：%d bytes/s" %(SIZE_DOWNLOAD))
print("HTTP頭部大小：%d byte" %(HEADER_SIZE))
print("平均下載速度：%d bytes/s" %(SPEED_DOWNLOAD))
#關閉文件及Curl對象
indexfile.close()
c.close()

四、驗證
