Using Pycurl to monitor HTTP response time script sharing in Python _python

Recently need to the node to the source station to do their own monitoring, simple ping can detect some things, but the HTTP request check also to carry out, so we studied the next pycurl.

Pycurl is a C-language Python library, although it is said to be not so pythonic, but very efficient, it supports the majority of the protocols:

Supporting FTP, FTPS, HTTP, HTTPS, GOPHER, TELNET, DICT, FILE and LDAP. Libcurl supports HTTPS certificates, HTTP POST, HTTP put, FTP uploading, Kerberos, HTTP form based upload, proxies, cookie S, user+password authentication, File transfer resume, HTTP proxy tunneling and more!

This is a lot of agreement, I need to be the HTTP one, relative to Urlib, this library may be faster.

The following script checks for a given URL, prints out the HTTP corresponding code, responds to the size, establishes the connection time, prepares the transmission time, transmits the first byte time, completes the time.

#!/usr/bin/python # coding:utf-8 Import stringio import pycurl import sys import OS class test:def __init__ (self): self.contents = ' def body_callback (self,buf): self.contents = self.contents + buf def test_gzip (Inpu T_url): T = Test () #gzip_test = File ("Gzip_test.txt", ' w ') c = Pycurl. Curl () c.setopt (Pycurl. Writefunction,t.body_callback) c.setopt (Pycurl). ENCODING, ' gzip ') c.setopt (Pycurl. Url,input_url) c.perform () Http_code = C.getinfo (pycurl. Http_code) Http_conn_time = C.getinfo (pycurl. Connect_time) Http_pre_tran = C.getinfo (pycurl. Pretransfer_time) Http_start_tran = C.getinfo (pycurl. Starttransfer_time) Http_total_time = C.getinfo (pycurl. Total_time) http_size = C.getinfo (pycurl. size_download) print ' Http_code http_size conn_time pre_tran start_tran ' print '%d%d total_time%f%f%f '% (%f P_code,http_size,http_conn_time,http_pre_tran,http_start_tran,http_total_time) If __name__ = = ' __main__ ': INput_url = sys.argv[1] Test_gzip (Input_url)
