1. 用requests库和BeautifulSoup库,爬取校园新闻首页新闻的标题、链接、正文、show-info。
2. 分析info字符串,获取每篇新闻的发布时间,作者,来源,摄影等信息。
3. 将字符串格式的发布时间转换成datetime类型
4. 使用正则表达式取得新闻编号
5. 生成点击次数的Request URL
6. 获取点击次数
7. 将456步骤定义成一个函数 def getClickCount(newsUrl):
8. 将获取新闻详情的代码定义成一个函数 def getNewDetail(newsUrl):
9. 尝试用使用正则表达式分析show info字符串,点击次数字符串。
