Twisted TimerService的使用

TimerService是twisted里提供的一个对loopingcall的service封装。

是在服务运行的期间反复执行某个方法的手段,文档里没有，其实也很简单。

from twisted.application import service, internet
from twisted.application.internet import TimerService
from twisted.python import log
import sys
#log.startLogging(sys.stdout)
#log.startLogging(open('./log.txt', 'w'))
application = service.Application('RSSServer')
def test():
    #log.msg('looping')
    print 'looping'
ts = TimerService(1, test)
ts.setServiceParent(application)

现在twistd -noy 一下，应该看到服务正常循环调用。换个log方式，以twisted log的方法。

运行一下，试一试。呵呵。
