Hi, it is my first time use twisted . i want to use the a function pass a url then get the web page the code as : // *some code call getPage* *while id <= 10000000: getPage("**http://www.mywebsite.com/News.aspx?ID="+str(id*<http://www.mywebsite.com/News.aspx?ID="+str(id> *)) id += 1 *//****************************************** *the getPage is definition in twisted.web.client* *def getPage(url, contextFactory=None, *args, **kwargs): """Download a web page as a string.* * Download a page. Return a deferred, which will callback with a page (as a string) or errback with a description of the error.* * See HTTPClientFactory to see what extra args can be passed. """ scheme, host, port, path = _parse(url) factory = HTTPClientFactory(url, *args, **kwargs) if scheme == 'https': from twisted.internet import ssl if contextFactory is None: contextFactory = ssl.ClientContextFactory() reactor.connectSSL(host, port, factory, contextFactory) else: reactor.connectTCP(host, port, factory) return factory.deferred* -------------------------------------------------------------------------------- *Question: *for the getPage function,if use it to get 10000 page ,it would open/close connection 10000 times,it is a very large cost。 So ,any body can give me some advice?creat a class inherit from HTTPPageGetter(as a protocol class) or HTTPClientFactory?
