python之web业务质量检测

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!
