Using Pycurl to monitor HTTP response time script sharing in Python

Recently need to monitor the node to the source station itself, a simple ping can detect something, but the HTTP request for the check also to be carried out, so studied the next pycurl.

Pycurl is a Python library implemented in C, although it is said to be not so pythonic, but very efficient, it supports the majority of 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 heap of protocols is already a lot, I need to be HTTP one, relative urlib, this library may be faster.

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

#!/usr/bin/python# coding:utf-8import stringioimport pycurlimport sysimport osclass test:def __init__ (self): s  elf.contents = "Def body_callback (self,buf): self.contents = self.contents + bufdef test_gzip (input_url): t = Test () #gzip_test = File ("Gzip_test.txt", ' w ') c = 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 total_time ' print '%d%d%f%f%f%f "% (http_ 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)

Pycurl Some of the response information:

Pycurl. Namelookup_time Domain name resolution time Pycurl. Connect_time Remote server connection time Pycurl. Pretransfer_time the time pycurl after the connection is over to the start of the transfer. Starttransfer_time receives the time Pycurl of the first byte. Total_time the total time of the last request Pycurl. Redirect_time If there is a turn, the time spent is pycurl. Effective_urlpycurl.http_code HTTP Response Code Pycurl.
