Python 执行javaScript代码
作者:互联网
引入第三方包
pip install PyExecJS -i https://mirrors.aliyun.com/pypi/simple/
或者 pip insyall PyExecJS
调用js文件进行方法执行
import execjs
Passwd = execjs.compile(open(r"web.js").read()).call('deba','Zabc')
print(Passwd)
将下面的js 保存为web.js文件
function base64decode(str) {
var base64EncodeChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
var base64DecodeChars = new Array(-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, 62, -1, -1, -1, 63, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, -1, -1, -1, -1, -1, -1, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, -1, -1, -1, -1, -1, -1, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, -1, -1, -1, -1, -1);
var c1, c2, c3, c4;
var i, len, out;
len = str.length;
i = 0;
out = "";
while (i < len) {
do {
c1 = base64DecodeChars[str.charCodeAt(i++) & 255]
} while (i < len && c1 == -1);
if (c1 == -1) {
break
}
do {
c2 = base64DecodeChars[str.charCodeAt(i++) & 255]
} while (i < len && c2 == -1);
if (c2 == -1) {
break
}
out += String.fromCharCode((c1 << 2) | ((c2 & 48) >> 4));
do {
c3 = str.charCodeAt(i++) & 255;
if (c3 == 61) {
return out
}
c3 = base64DecodeChars[c3]
} while (i < len && c3 == -1);
if (c3 == -1) {
break
}
out += String.fromCharCode(((c2 & 15) << 4) | ((c3 & 60) >> 2));
do {
c4 = str.charCodeAt(i++) & 255;
if (c4 == 61) {
return out
}
c4 = base64DecodeChars[c4]
} while (i < len && c4 == -1);
if (c4 == -1) {
break
}
out += String.fromCharCode(((c3 & 3) << 6) | c4)
}
return out
};
function deba(stt) {
var photosr = new Array();
packed=stt
eval(eval(base64decode(packed).slice(4)));
return photosr
}
直接执行简单的js代码
import execjs
js = execjs.compile('''function sum(i,j){sum=i+j;return sum}''')
result = js.call('sum', 1, 2)
print(result)
