淘宝x-sign算法demo示例

用xposed hook这个方法就可以拿到对应的签名，需要可以留言

 public String getMtopApiSign(HashMap<String, String> params, String appKey, String authCode) {
        String instanceId = getInstanceId();
        if (params == null) {
            TBSdkLog.e("mtopsdk.InnerSignImpl", instanceId + " [getMtopApiSign] params is null.appKey=" + appKey);
            return null;
        } else if (appKey == null) {
            params.put("SG_ERROR_CODE", "AppKey is null");
            TBSdkLog.e("mtopsdk.InnerSignImpl", instanceId + " [getMtopApiSign] AppKey is null.");
            return null;
        } else if (this.sgMgr == null) {
            params.put("SG_ERROR_CODE", "SGManager is null");
            TBSdkLog.e("mtopsdk.InnerSignImpl", instanceId + " [getMtopApiSign]SecurityGuardManager is null,please call ISign init()");
            return null;
        } e
