Python 刮痧罐头'；我没有得到正确的答复

我试图从中获取song&singerdata，但无法获得正确的响应

我查看了scrapy shell，当我请求“music.163.com/#/artist？id=16686”时，响应是“music.163.com”。我不知道原因

下面是日志

您的

start\u URL

似乎不正确。如果您查看“网络”选项卡和页面源，您会注意到唱片集/歌曲数据实际上包含在一个

标记中，这导致几乎相同的url，只是没有

：

之后，

parse_相册

中的歌曲xpath不正确。我把它和这个一起工作：

"//ul[@class='f-hide']/li/a/@href[contains(.,'song')]"

---

之后一切似乎都正常。

这是Ajax驱动的URL：因此，

之后的所有部分都没有得到正确处理。尝试使用

AjaxCrawlMiddleware

，但是Scrapy不能很好地处理ajaxURL。

Thx Granit。但我似乎无法获得“”上的评论编号。我可以通过使用“//span[@id=“cnt\u comment\u count”]/text（）”获取html消息是61，但无法获取数字。这是因为“#”使用了Ajax吗？

"http://music.163.com/#/artist/album?id=16686"
# becomes:
"http://music.163.com/artist/album?id=16686"

"//ul[@class='f-hide']/li/a/@href[contains(.,'song')]"
