将结果写入D:/aa.txt里面http://www.cndba.cn/hbhe0316/article/107842http://www.cndba.cn/hbhe0316/article/107842http://www.cndba.cn/hbhe0316/article/107842http://www.cndba.cn/hbhe0316/article/107842http://www.cndba.cn/hbhe0316/article/107842http://www.cndba.cn/hbhe0316/article/107842http://www.cndba.cn/hbhe0316/article/107842
