华为云照片的爬虫程序更新(python3.6)

一、背景:

每年终都有一个习惯,就是整理资料进行归档,结果发现手机照片全备份在华为云里,在官网上找了一圈,没找到官方的pc工具用来同步照片。

于是找出上次写的程序,看看能不能爬到数据,然而……果然不好用。因为华为在登录上又增加了一些验证机制,譬如:账号保护

华为云照片的爬虫程序更新(python3.6)_第1张图片

抓了一下报文,发现逻辑变复杂了很多,部分逻辑还封装在js里。

算了,懒得琢磨了,直接用selenium吧。

二、实现思路:

1、用Python + selenium +浏览器 ,人工登录,保存cookie及签名信息。

2、再调用requests加第一步保存的cookie和前面,直接向后台发post请求,获取数据。

思路确定,开干。

三、开发环境:

1、python3.6,在最近的一个项目中由于多次遇到中文问题,实在是烦不胜烦,所以就把开发工具升级到了py3,确实方便多了。

说到py2升到py3,虽然还是有些写法调整,有些包在py3下不支持,但总体来说,迁移很平稳,写法问题,百度一下基本就可以解决。

我用的Anaconda的python包。

3.6.3 |Anaconda custom (64-bit)| (default, Oct 15 2017, 03:27:45) [MSC v.1900 64 bit (AMD64)]
Python Type "help", "copyright", "credits" or "license" for more information.

 

2、selenium 3.9.0,用conda现安装的。

conda install selenium 

3、浏览器,试用了firefox,edge,chrome,phantomjs,分别版本如下:

firefox: 58.0.2 (64 位)
edge: Microsoft Edge 41.16299.248.0 ,Microsoft Edge 41.16299.248.0
chrome: 版本 63.0.3239.132(正式版本) (32 位)
phantomjs: 2.1.1 

另外,操作系统:Microsoft Windows [版本 10.0.16299.248]

 

 

4、浏览器驱动:

firefox驱动,https://github.com/mozilla/geckodriver/releases/,支持 Firefox 55及以上版本。

edge驱动,https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/#downloads,最新版本 Release 16299,Version: 5.16299,支持 Edge version supported: 16.16299 。注意edge驱动只有在edge浏览器未启动的情况下才能正常运行,否则会报错。

chrome驱动,https://sites.google.com/a/chromium.org/chromedriver/downloads,这里需要注意的是:最新版本是2.35(不是2.9),2.35才支持chrome 61-63版本。

phantomjs,http://phantomjs.org/download.html,phantomjs可以理解成没有界面的浏览器,所以驱动跟浏览器是一体的。

驱动版本一定要选对,否则会有奇奇怪怪的问题。
