搜索结果为空判断错误

[0x80mem]

搜素微博时会出现这种情况：一页的内容非常少，远低于我这里的7条，推测可能微博屏蔽了某些内容，在最极端的情况下，一页可能什么都没有，这时就会出现搜索结果为空
因此parse_page似乎会提前终止
特别的，如果第一页什么都没有，就会导致诸如parse, parse_by_day之类的立即停止

这是我目前的改动

调整了搜索方式，使得搜索日期区间不相交（屏蔽情况的输出很随意，希望作者能调整一下）
parse_page能够处理屏蔽情况
get_article_url似乎不能正常工作，做了相应调整

另外很早以前的微博视频链接不能正常爬取（我这里是2014年）

调整了搜索方式，使得搜索日期区间不相交（屏蔽情况的输出很随意，希望作者能调整一下） parse_page能够处理屏蔽情况 get_article_url似乎不能正常工作，做了相应调整

另外很早以前的微博视频链接不能正常爬取（我这里是2014年）

您好～请问按这样重新调整就可以避免首页空白的情况吗？ 另外，作者在很多地方提醒大家def pase_by_hour部分需要修改，我看您这里还是原始版本的code，这里我按照作者的意思做了如下修改，您觉得是否可以呢？
