python - 抓取一个小说网站嵌入式广告内容-PHP中国語ネットワークQ&A

目标地址：http://m.dingdianzw.com/wapbo...

不过需要用谷歌浏览器模拟手机端打开，然后才能看到低端的广告内容

这个内容应该是嵌入在js中的

如果你刷新出的的是一张图片地址链接，就多刷新几次，他有几种广告方式，我是要抓取这种嵌入在js内容中的

现在的问题是，这种情况下，要怎么抓取到这个广告图片的。

直接网页上看可以看到图片内容，现在关键是要用代码去抓，因为后面不止是要抓这一张图，想要操作更多的图片，基本都是这样类型的，然后这种类型又不知怎么爬下来的。

py代码

from bs4 import BeautifulSoup
import requests


pageUrl = r'http://m.dingdianzw.com/wapbook/2430.html'


headers = {
    "Accept":"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
    "Accept-Encoding":"gzip, deflate, sdch",
    "Accept-Language":"zh-CN,zh;q=0.8",
    "Cache-Control":"max-age=0",
    "Connection":"keep-alive",
    "Host":"m.dingdianzw.com",
    "Upgrade-Insecure-Requests":"1",
    "User-Agent":"Mozilla/5.0 (Linux; Android 5.0; SM-G900P Build/LRX21T) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.23 Mobile Safari/537.36",
}

pageText = requests.get(pageUrl,headers=headers).text
pageSoup = BeautifulSoup(pageText,'lxml')

print pageSoup

页面分析出来只有下面这些内容
