python脚本测试网站响应时间

可以使用Firefox的Firebug插件查看网站的响应时间，今天我们用python实现这个功能。

#!/usr/bin/env python

#coding=utf8
#Author zhaodong
import  os,sys
import  time
import  sys
import  pycurl
URL=sys.argv[1]
#uURL="http://www.baidu.com"
c = pycurl.Curl()
c.setopt(pycurl.URL, URL)

#连接超时时间,5秒
c.setopt(pycurl.CONNECTTIMEOUT, 5)

#下载超时时间,5秒
c.setopt(pycurl.TIMEOUT, 5)
c.setopt(pycurl.FORBID_REUSE, 1)
c.setopt(pycurl.MAXREDIRS, 1)
c.setopt(pycurl.NOPROGRESS, 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,e:
        print  "connecion error:" +str(e)
        indexfile.close()
        c.close()
        sys. exit ()

NAMELOOKUP_TIME =  c.getinfo(c.NAMELOOKUP_TIME)  #DNS解析时间
CONNECT_TIME =  c.getinfo(c.CONNECT_TIME)   #获取建立连接时间
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)

indexfile.close()
c.close()
