HTTP service requires Pycurl module to monitor the service

Recent operation is still relatively idle, write a piece of their own experience. You should have done the HTTP service for the OPS. Like some electronic mall, or some internet companies, Web services, such as is crucial, recently read the Liu Tians eldest brother's book feel that their operation and maintenance platform should also be able to monitor the service, and so on, today learned the Pycurl module, here to record:

Module-related description: c = Pycurl. Curl ()     #创建一个curl对象   c.setopt (pycurl. ConnectTimeout, 5)     #连接的等待时间, set to 0 do not wait   c.setopt (pycurl. TIMEOUT, 5)     #请求超时时间   c.setopt (pycurl. noprogress, 0)     #是否屏蔽下载进度条, not 0 shielded   c.setopt (Pycurl. Maxredirs, 5)     #指定HTTP重定向的最大数   c.setopt (pycurl. Forbid_reuse, 1)     #完成交互后强制断开连接, do not reuse   c.setopt (Pycurl. fresh_connect,1)     #强制获取新的连接, which is the replacement of connections in the cache   c.setopt (pycurl. dns_cache_timeout,60)     #设置保存DNS信息的时间, default is 120 seconds   c.setopt (Pycurl.

All right, let's just write a script to get this job done: Direct code: #!/usr/bin/env python #-*-coding:utf-8-*-import os,sys import time Import sys Import Pycurl

Class Test:     def __init__ (self):         self.contents = '      def callback (Self,curl):         self.contents = self.contents + Curl def test_gzip (URL):     t = Test ()     C = Pycurl. Curl ()       c.setopt (Pycurl. Writefunction,t.callback)     c.setopt (Pycurl. ENCODING, ' gzip ')     c.setopt (Pycurl. Url,input_url)     c.perform ()         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 Status code:%s"% (http_code)       print "DNS resolution time:%.2f MS"% ( namelookup_time*1000)       print "Establish connection time:%.2f ms"% (connect_time*1000)       Print "Ready to transfer time:%.2f MS"% (pretransfer_time*1000)       print "Transfer start time:%.2f ms"% (starttransfer_time*       print "Total transfer end time:%.2f MS"% (total_time*1000)       print "Download packet size:%d BYTES/S "% (size_download)       print" HTTP header size:%d byte "% (header_size)       print "Average download speed:%d bytes/s"% (speed_download)   if __name__ = = ' __main__ ':     url = sys.argv[1]  &n bsp;  test_gzip (URL)

#备注, the reason for writing a class function is because, pycurl. Writefunction Here we define is to return a function, and then we give an empty function is good, originally tried to generate file results can not be generated.
