使用pycurl探测web服务质量
1:pycurl模块的安装方法
easy_install pycurl pip install pycurl
2:示例代码如下,是在python3下实现的,如若使用python2稍作修改即可
# -*- coding: utf-8 -*- import os,sys import time import sys import pycurl URL="https://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 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("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()
