关键代码快速定位-Base64

Java.perform(function () {
    console.log("--------------start hooking--------------");
    function showStack() {
        var log = Java.use("android.util.Log");
        var Throwable = Java.use("java.lang.Throwable");
        console.log(log.getStackTraceString(Throwable.$new()))
    }
    var base64 = Java.use("android.util.Base64");
    base64.encodeToString.overload('[B', 'int').implementation = function (a, b) {
        showStack();
        console.log("base64.encodeToString: ", JSON.stringify(a));
        var result = this.encodeToString(a, b);
        console.log("base64.encodeToString result: ", result)
        return result;
    }
    var base64 = Java.use("android.util.Base64");
    base64.encodeToString.overload('[B', 'int', 'int', 'int').implementation = function (a, b,c,d) {
        showStack();
        console.log("base64.encodeToString: ", JSON.stringify(a));
        var result = this.encodeToString(a, b,c,d);
        console.log("base64.encodeToString result: ", result)
        return result;
    }
})

除此之外，还有另几个base64实现方法：
java.net.URLEncoder
java.util.Base64
okio.Base64
okio.ByteString
