python3执行js之pyexecjs

执行js的三种方法：
1、阅读js代码，将之转成python
2、找到js代码，用python第三方库执行相关代码 python2-pyv8 python3-pyexecjs
3、用selenium驱动浏览器

pyexecjs
pip install pyexecjs
使用：

import execjs

e = execjs.eval('a = new Array(1,2,3)')#获取js环境，直接执行js代码，适用于较简单的运算
c = execjs.compile('''
    function add(x,y){
        return x+y;
    };
''') #加载js代码，使之应用到当前环境

print(e) #[1,2,3]
print(c)# <execjs._external_runtime.ExternalRuntime.Context object at 0x000001B84A8AD780> 加载这个函数到环境
print(c.call('add','1','2')) #调用 add函数，参数为'1'和'2'

如果使用python执行js代码，注意不能出现和页面有交互的代码

执行js文件

with open ('1.js',encoding='utf-8') as f:
    js_data = f.read()
c = execjs.compile(js_data)
code = "add('{}','{}')".format(x,y) #add是文件中的某个函数,x y是传入的参数
c.eval(code)

案例：爬取落网单曲

分析：

落网单曲中的歌曲是个MP3文件，每次打开在<audio>标签中播放，但是在源代码中，找不到mp3文件的链接。

每次切换歌曲，<audio>标签中的src会变化，指向不同的地址。所以我们猜测歌曲的src是由JS生成，而且每次切歌，都会触发JS事件得到新的src。我们在audio标签打上一个断点

每当src变化时就会暂停，我们可以进而查看JS。

我们知道切歌时执行的是什么代码了，现在要得到所有的歌曲链接，我们可以在右边的调用栈里逐条分析。一般jq文件不需要关心。

经过分析，我们大概知道：每次切歌，代码会把当前需要播放的歌曲的编号传给一个函数。函数接收到编号之后，就在播放列表里播放相应歌曲。所以我们的目的是得到播放列表。

像上面这样，里面由所有歌曲信息，但是调用它的是this对象，this在js里面相当于python中的self，一般用于函数里面当作对象本身。也就是说，谁触发这个函数就是谁，并没有直接定义，所以这种也不能算找到生成列表的JS代码。

像这样luooPlayer.playlist里面有所有歌曲信息，我们就知道，歌曲信息是存在luooPlayer对象中的playlist属性里，我们就在这个JS文件中搜索luooPlayer对象

 

我们发现playlist定义在luooPlayer对象之前，并且作为一个参数传进来而生成luooPlayer对象，所以我们接着搜索playlist的定义，发现就在前几行。

var playlist = GibberishAES.dec(pl, $.luoo.cfg.aes))

pl和$.luoo.cfg.aes的值在源文件中可以搜到是一串固定的字符串，我们直接调用这个函数，然后把这两个参数传进去即可。现在我们的难题是得到这个函数，这个时候，我们可以在这个定义playlist的地方打上一个断点，然后用单步进入的方式，得到函数代码！

复制出JS代码，然后逐步分析，若有调用其他函数和变量，就单步进入或搜索，直至这个N函数能正常执行。
