Hook淘宝X-SIGN

版本9.16.0
直接搜索x-sign，找到InnerProtocolParamBuilderImpl

smali

可以发现是调用了pha的 a方法
找到pha的子类phb

直接调用它的a方法

public void getSignStr2(Object instance) {
        Map map1 = new HashMap<>();
        map1.put("data", "{}");
        map1.put("api", "mtop.mediaplatform.live.channel.list");
        map1.put("lng", "116.494988");
        map1.put("lat", "39.990174");
        map1.put("utdid", "XqAA0BugnloDAJBCLRn35KVF");
        map1.put("extdata", "openappkey=DEFAULT_AUTH");

        long time = System.currentTimeMillis() / 1000;
        map1.put("t", time + "");
        map1.put("v", "1.0");
        map1.put("appKey", "21646297");
        Map map2 = new HashMap<>();

        map2.put("pageName", "com.taobao.taolivehome.TaoLiveHomepageActivity");
        Map o = (Map) XposedHelpers.callMethod(instance, "a", map1, map2, "21646297", null, false);
        for (Map.Entry entry : o.entrySet()) {
            Log.e(TAG, "getSignStr: " + entry.getKey() + "====" + URLEncoder.encode(entry.getValue()));
        }
        Log.e(TAG, "end: " + time);

    }
