Question

import url_manager, html_downloader, html_parser,html_outputer

class SpiderMain(object):

def _init_(self):

self.urls = url_manager.UrlManager()

self.downloader = html_downloader.htmlDownloader()

self.parser = html_parser.HtmlParser()

self.outputer = html_outputer.HtmlOutputer()

def craw(self, root_url):

count = 1

self.urls.add_new_url(root_url)

while self.urls.has_new_url():

try:

new_url = self.urls.get_new_url()

print('craw %d :  %s' % (count, new_url))

html_cont = self.downloader.download(new_url)

new_urls, new_data = self.parser.parse(new_url, html_cont)

self.urls.add_new_urls(new_urls)

self.outputer.collect_data(new_data)

if count == 1000:

break

count = count + 1

except:

print ('craw failed')

self.outputer.output_html(new_data)

if __name__ == '__main__':

root_url = "http://baike.baidu.com/item/Python/407313?fr=aladdin"

obj_spider = SpiderMain()

obj_spider.craw(root_url)

找了很久也没找到原因，谢谢！

12行报错 你查看下 你UrlManager这个类中,urls变量是不是写对了  感觉可能是你add_new_url()参数写错了
