python执行函数是语句吗_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JSvar radra27radra27 = "D";

var ra72419ra91ra72419ra91 = "7.241.9" + ".";

var raurst500ra63raurst500ra63 = "urst=500";

var ravalidtora49ravalidtora49 = "validto=";

var raevphncdra57raevphncdra57 = "ev.ph" + "ncd";

var ra16067161ra17ra16067161ra17 = "16067161";

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

var ra1080p4ra73ra1080p4ra73 = "/1080P_4";

var ra209hashra72ra209hashra72 = "209&hash";

var ra2bmkdz7nra36ra2bmkdz7nra36 = "2BMKd" + "z7N";

var ra6708909ra29ra6708909ra29 = "6708909" + "&";

var ra00kip4ra41ra00kip4ra41 = "00k&i" + "p=4";

var ra006163ra73ra006163ra73 = "006/16/" + "3";

var raro7upu3ra66raro7upu3ra66 = "Ro7UPU%3";

var raroiu6qra26raroiu6qra26 = "=rOiU6q%";

var ra075351mra26ra075351mra26 = "075351." + "m";

var ramgdmctbvra11ramgdmctbvra11 = "MgdmCtbV";

var rap4validra25rap4validra25 = "p4?valid";

var ra09ratera79ra09ratera79 = "09&rate=";

var rancomvira35rancomvira35 = "n.com/vi";

var ra24075351ra94ra24075351ra94 = "24075" + "351";

var ra000k324ra70ra000k324ra70 = "000K_324";

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

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 ravalidtora49ravalidtora49 = "validto=";

var raevphncdra57raevphncdra57 = "ev.ph" + "ncd";

var ra16067161ra17ra16067161ra17 = "16067161";

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

var ra1080p4ra73ra1080p4ra73 = "/1080P_4";

var ra209hashra72ra209hashra72 = "209&hash";

var ra2bmkdz7nra36ra2bmkdz7nra36 = "2BMKd" + "z7N";

var ra6708909ra29ra6708909ra29 = "6708909" + "&";

var ra00kip4ra41ra00kip4ra41 = "00k&i" + "p=4";

var ra006163ra73ra006163ra73 = "006/16/" + "3";

var raro7upu3ra66raro7upu3ra66 = "Ro7UPU%3";

var raroiu6qra26raroiu6qra26 = "=rOiU6q%";

var ra075351mra26ra075351mra26 = "075351." + "m";

var ramgdmctbvra11ramgdmctbvra11 = "MgdmCtbV";

var rap4validra25rap4validra25 = "p4?valid";

var ra09ratera79ra09ratera79 = "09&rate=";

var rancomvira35rancomvira35 = "n.com/vi";

var ra24075351ra94ra24075351ra94 = "24075" + "351";

var ra000k324ra70ra000k324ra70 = "000K_324";

var ra50000kbra49ra50000kbra49 = "50000k&" + "b";

var rahttpsra83rahttpsra83 = "https://";

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

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
