python通過mechanize模塊實現不斷刷新網頁的功能

python通過mechanize模塊實現不斷刷新網頁的功能，你可以通過命令行指定一個網頁，程序將通過瀏覽器打開此頁面并且不斷的刷新，可以通過鍵盤隨時終止，mechanize模塊可以通過easy_install或者pip安裝

import mechanize
import sys

def usage():
    print "Usage: python" + ' ' + sys.argv[0] + ' ' + "<url>"
    sys.exit()
def reloader():
    br = mechanize.Browser()
    reload_count = 0
    url = sys.argv[1]
    start = br.open(url)

while True:
    try:
        br.reload()
        reload_count += 1
        print "[+] Sent reload request", "%s" % (reload_count)
    except KeyboardInterrupt:
        sys.exit("\nProcess aborted.")


if len(sys.argv) < 2:
    usage()
if name == "main":
    reloader()</pre>
