python执行js语句，无函数返回值

有时候在JS代码里面抠出部分语句，但是不是一个函数。
如下面的一段JS

var radra27radra27 = "D";

var ra72419ra91ra72419ra91 = "7.241.9" + ".";

var raurst500ra63raurst500ra63 = "urst=500";

flashvars_324075351["quality_1080p"] = quality_1080p;

做了很多的运算，掩人耳目，虽然看多几下，用python写也简单，或者把它放入一个function里面也可以。
比如实时网络上下载获取一段js，然后再在头部和尾部组装为function。
function getValue(){
xxxxxx
xxxxxx
return flashvars_324075351
}
 
然后执行这一段JS，call返回函数 getValue() 就可以拿到返回值了。
 
不过今天我们用其他的方法直接获取flashvars_324075351
 
使用jsp库即可。
 
把上面的JS语句

var radra27radra27 = "D";

var ra72419ra91ra72419ra91 = "7.241.9" + ".";

var raurst500ra63raurst500ra63 = "urst=500";

var radeos202ra16radeos202ra16 = "deos/20" + "2";

var ra1080p4ra73ra1080p4ra73 = "/1080P_4";

var rafrom160ra56rafrom160ra56 = "from=16" + "0";

var quality_1080p =/* + radra27radra27 + */rahttpsra83rahttpsra83 + /* + rancomvira35rancomvira35 + */raevphncdra57raevphncdra57 + /* + radra27radra27 + */rancomvira35rancomvira35 + /* + ra006163ra73ra006163ra73 + */radeos202ra16radeos202ra16 + /* + ra09ratera79ra09ratera79 + */ra006163ra73ra006163ra73 + /* + ra1080p4ra73ra1080p4ra73 + */ra24075351ra94ra24075351ra94 + /* + raroiu6qra26raroiu6qra26 + */ra1080p4ra73ra1080p4ra73 + /* + ra000k324ra70ra000k324ra70 + */ra000k324ra70ra000k324ra70 + /* + rancomvira35rancomvira35 + */ra075351mra26ra075351mra26 + /* + ravalidtora49ravalidtora49 + */rap4validra25rap4validra25 + /* + ra209hashra72ra209hashra72 + */rafrom160ra56rafrom160ra56 + /* + ra1080p4ra73ra1080p4ra73 + */ra6708909ra29ra6708909ra29 + /* + ra209hashra72ra209hashra72 + */ravalidtora49ravalidtora49 + /* + ramgdmctbvra11ramgdmctbvra11 + */ra16067161ra17ra16067161ra17 + /* + ra24075351ra94ra24075351ra94 + */ra09ratera79ra09ratera79 + /* + ra50000kbra49ra50000kbra49 + */ra50000kbra49ra50000kbra49 + /* + ramgdmctbvra11ramgdmctbvra11 + */raurst500ra63raurst500ra63 + /* + ra209hashra72ra209hashra72 + */ra00kip4ra41ra00kip4ra41 + /* + raroiu6qra26raroiu6qra26 + */ra72419ra91ra72419ra91 + /* + ra09ratera79ra09ratera79 + */ra209hashra72ra209hashra72 + /* + raro7upu3ra66raro7upu3ra66 + */raroiu6qra26raroiu6qra26 + /* + ra075351mra26ra075351mra26 + */ra2bmkdz7nra36ra2bmkdz7nra36 + /* + ra50000kbra49ra50000kbra49 + */ramgdmctbvra11ramgdmctbvra11 + /* + radeos202ra16radeos202ra16 + */raro7upu3ra66raro7upu3ra66 + /* + ra075351mra26ra075351mra26 + */radra27radra27;

flashvars_324075351["quality_1080p"] = quality_1080p;

后面加一个返回值，但不需要加return
比如

....

ra50000kbra49ra50000kbra49 + */ramgdmctbvra11ramgdmctbvra11 + /* + radeos202ra16radeos202ra16 + */raro7upu3ra66raro7upu3ra66 + /* + ra075351mra26ra075351mra26 + */radra27radra27;

flashvars_324075351["quality_1080p"] = quality_1080p;

flashvars_324075351;

然后直接调用jspy
res = js2py.eval_js(js)
 
执行后print(res） ， 显示的值就是flashvars_324075351
