通过UI自动化方式获取微信公众号文章、视频信息

出于学习研究,对某账号的文章、视频分析一翻,尝试使用自动化方式看能否获取相应信息。

获取某号的文章有多重方法:

第一种是通过搜狗浏览器搜索账号(这种方式每天只能获取一篇文章,基本上没啥用。):

第二种方式需要自己注册一个订阅号,注册账号有限制:

1、同一个邮箱只能申请1个账号;
2、同一个手机号码可绑定5个账号;
3、同一身份证注册个人类型账号数量上限为1个;
4、同一企业、个体工商户、其他组织资料注册账号数量上限为2个;
5、同一政府、媒体类型可注册和认证50个账号;
6、同一境外主体注册账号数量上限为1个。
意思是一个人只能注册一个号体,申请一个媒体或政府可以有50个,研究学习的话,一个够用了。
注册流程就不说了,注册登录好后,点击“草稿箱”--->‘写新图文’--->点击顶部的‘超链接’ -->账号处点击‘选择其他账号’--->输入需要获取文章的账号名称,点击查询,这时候可以看到,会把该账号的所有文章都获取到:

 

比如我们查询“央视网”,文章会按照发布日期倒序显示,这就是我们要获取的数据。我们自动化操作也就模拟到这个地方,剩下的就分析接口就行:

通过请求分析,获取文章的请求为:https://mp.weixin.qq.com/cgi-bin/appmsg?action=list_ex&begin=35&count=5&fakeid=MTI0MDU3NDYwMQ==&type=9&query=&token=441171486&lang=zh_CN&f=json&ajax=1

 

 接口返回数据很全,基本想要的数据都有了。

我们要做的事:

1.自动化模拟用户操作到当前动作,再获取请求连接,分析请求数据

2.直接调用这个接口获取数据,那么就要构造这个接口的请求参数,比如账号的id,cookie等,登录维护等。

比较两种方式,都有相应的好处,自动化只要登录后,输入账号名称即可,调用接口的话,不同的账号需要事先维护相应id等,直接调用接口更容易被封。

目前研究到的封禁规则为:每个号体可以调用接口60次,到了60次会被封禁1个小时,换IP也没用,1个小时候可以继续,多次被封禁后,封禁时间会变长,最长为24小时。

有人说,不调用接口,自动化后怎么获取这些请求?有两种方式:

1.安装mitmproxy,相比Charles、fiddler的优点在于,它可以命令行方式或脚本的方式进行mock

mitmproxy不仅可以像Charles那样抓包,还可以对请求数据进行二次开发,进入高度二次定制
大家可以先查看下官网的相关文档

mitmproxy 官网:https://www.mitmproxy.org/
mitmproxy很强大,但这个地方我们倒用不着。

1.seleniumwire 

Selenium Wire 扩展了Selenium 的Python 绑定,让您可以访问浏览器发出的底层请求。您编写代码的方式与编写 Selenium 的方式相同,但您会获得额外的 API 来检查请求和响应并动态更改它们。
mitmproxy 官网:https://github.com/wkeeling/selenium-wire
  • Pure Python, user-friendly API
  • HTTP and HTTPS requests captured
  • Intercept requests and responses
  • Modify headers, parameters, body content on the fly
  • Capture websocket messages
  • HAR format supported
  • Proxy server support
 seleniumwire 就完全够我们使用了。
 知道怎么做后,我们梳理一下我们需要准备什么东西:
1.环境安装
(1)python环境(略)
(2)chromedriver驱动下载:http://chromedriver.storage.googleapis.com/index.html
(3)mysql环境(略)
2.数据库设计

3. 分模块设计
(1)通过自动化获取基础文章信息,比如:封面图,文章访问连接,文章时间等
(2)自动化打开文章连接获取该文章含有视频的地址,文章详情中的视频有两类:
  A. 文章详情普通视频,一般可以直接分析请求下载到(如下文章详情中比较中规中矩的视频):
        
  B.文章详情插入的TX视频,该格式是m3u8格式,需要下载ts文件合成mp4,如果是TX视频,自动化时候首先要去点击一下播放按钮,不然获取不到m3u8地址:
  

   两种视频处理方式不一样,我的处理思路是:所有文章都拿连接去自动化,用selenium的显示等待方式,如果发现视频按钮,就去点击一下,然后获取所有的请求数据后续分析。

(3)直接请求原文章地址,通过bs4、lxml解析内容
  A. 去除不需要的格式
  B. 图片转存七牛 (转存后替换原内容中图片)
  C. 提取原视频标签(后边视频下载转存七牛并转码后需要替换这里)
  D. 提取其他标签,比如新闻来源、编辑、记者等字段
(4) 既然账号有封禁,可以考虑加入过个账号,一旦账号被封禁,则退出当前账号,用新的账号登录,把登录二维码发送到钉钉供扫码
  A. 自动化时,账号被封禁了查询文章时没有数据,接口返回也是有提示“freq control”
     B. 当账号被封禁时,往表中插入一条记录,并更新封禁时间,取账号时,判断封禁时间大于1小时才取。
  C. 其实用那个账号取决于用手机扫描的是谁,浏览器有登录缓存的,账号没被封禁前,我们一直用的浏览器缓存,这样自动化时候,我们就不用每次去扫二维码了,后边会讲。
  D. 需要登录时,把二维码截图发到钉钉群,这里页面自动化等待时间可以设置长一点,比如10分钟。

目前看TX视频都是m3u8格式,好在ts文件都是没有加密的,所以也就没做解密处理。

强调几点:

1.视频的封面图和视频,都是有vid的,通过vid相同来处理视频的封面图,也是根据vid来替换视频,比如一篇文章中有多个视频。

2.账号执行表是为了处理异常执行情况,比如执行到一半,被封禁了,下次执行又得所有账号在来一遍,浪费时间,所以加了一个patch来标志,没执行完的pitch继续执行,执行完了下次执行时最大的patch加1,这样

就保障了这些任务。
