在模拟登录过程中，有些目标网站的的密码会经过内部js进行加密，所以须对这过程进行模拟。须利用ScriptEngineManager类来执行其js

import java.io.InputStream;import java.io.InputStreamReader;import java.io.Reader;import javax.script.Invocable;import javax.script.ScriptEngine;import javax.script.ScriptEngineManager;public class Test{    public static Invocable invoke = null;    static {        ScriptEngineManager manager = new ScriptEngineManager();        ScriptEngine jsEngine = manager.getEngineByName("javascript");        String jsFileName = "xxxxx.js"; // 指定md5加密文件        Reader reader;        try {            InputStream in = Test.class.getClassLoader()                    .getResourceAsStream(jsFileName);            reader = new InputStreamReader(in);            jsEngine.eval(reader);            reader.close();        } catch (Exception e) {            e.printStackTrace();        }        invoke = (Invocable) jsEngine;    }    public static String getPassEncoding(String pubKey, String serverTime,            String nonce,String password) {        String pass = null;        try {            pass = (String) invoke.invokeFunction("getPassEncoding", new Object[] {                    pubKey, serverTime,nonce,password});        } catch (Exception e) {            System.out.println("为登陆密码加密时，出现异常!");            e.printStackTrace();        }        return pass;    }    public static void main(String[] args) {    }}
