按上面我们会遇到一个问题，就是拿不到一个用户的所有文章，一个专题的所有文章，解决方案：离线网页，再抓取网页源码

# 从本地一个html文件中解析出文章的id
def getArticalIDStringFromLocalHtmlFile(localHtmlFilePath):
    with open(r'%s'%localHtmlFilePath, "r") as f:
        page = f.read()
    commentsIDStrings = re.findall('<a class="title" target="_blank" href="http://www.jianshu.com/p/(.*?)">',page,re.S)
    return commentsIDStrings

# 这里我们可以开始调用了，这里要写全路径 不能写 ~/Desktop
articalIDStrings = getArticalIDStringFromLocalHtmlFile('/Users/mac/Desktop/test.htm')
for articalIDString in articalIDStrings:
    likeArticle(articalIDString)
