我正在尝试将 js 函数转换为 java
function keygen(code, serial) {
code = parseInt(/([0-9-]{12})/.exec(code)[0].replace(/-/g, ''))
return ((code + 0x26946948) ^ parseInt(serial.replace(/-/g, ''), 16)) >>> 0
}
keygen('7043-1667-03f9-f6', 'C6AD-0E40')上面的代码返回 214930807，这是正确的数字
但是在java中我做到了
private long keygens(String code) {
int c =Integer.parseInt(code.substring(0, 12).replaceAll("[a-zA-Z-]", "").replaceFirst("^0+(?!$)", ""))+647260488;
String s=executeVolCommand().replaceAll("[-]", "");
long dec=Long.parseUnsignedLong(s,16);
System.out.print(executeVolCommand());
return (c^dec)>>>0;
}
public String executeVolCommand()
{
String NEWLINE = System.getProperty("line.separator");
StringBuffer buffer = new StringBuffer();
try{
Process pb = new ProcessBuilder("cmd","/c", "vol").start();
InputStream in = pb.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String line;
while ((line = br.readLine()) != null) {
buffer.append(line + NEWLINE);
}
}
catch(Exception e){e.printStackTrace();}
String s= buffer.toString().trim();
String[] words = s.split(" ");
String lastWord = words[words.length - 1];
return lastWord;
}
但是我收到了这个错误

另外，如果我将 7043-1667-03f9-f6 更改为 0043-1667-03f9-f6 错误消失，但 ofc 会给出错误的号码
<小时 />另外，我尝试在java代码中调用js文件，但它返回2.14930807E8
private String keygens(String code) throws ScriptException, IOException, NoSuchMethodException {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("JavaScript");
// read script file
engine.eval(Files.newBufferedReader(Paths.get("C:/Users/MJ/eclipse-workspace/SM_keygen2/js/keygen.js"), StandardCharsets.UTF_8));
Invocable inv = (Invocable) engine;
// call function from script file
Object s = inv.invokeFunction("keygen", code,executeVolCommand());
System.out.println(s);
return s.toString();
}
public String executeVolCommand()
{
String NEWLINE = System.getProperty("line.separator");
StringBuffer buffer = new StringBuffer();
try{
Process pb = new ProcessBuilder("cmd","/c", "vol").start();
InputStream in = pb.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String line;
while ((line = br.readLine()) != null) {
buffer.append(line + NEWLINE);
}
}
catch(Exception e){e.printStackTrace();}
String s= buffer.toString().trim();
String[] words = s.split(" ");
String lastWord = words[words.length - 1];
return lastWord;
}
感谢任何帮助
请您参考如下方法:
您需要使用Long.parseLong个code和serial
public class HelloWorld {
public static void main(String[] args) {
// result: 214930807
System.out.println("result: " + keygen("7043-1667-03f9-f6", "C6AD-0E40") );
}
private static int keygen(String code, String serial) {
return (int)((Long.parseLong(code.substring(0,12).replaceAll("[a-zA-Z-]",""))+0x26946948)^Long.parseLong(serial.replaceAll("[-]", ""),16));
}
}
