ajpuhs.setAlias 回调没有调用 初始化

if (systemType != "ios") {
      ajpush.init(function (ret) {
        console.log(JSON.stringify(ret));
        if (ret && ret.status==1) {
          //  初始化成功
          console.log('初始化成功')
          console.log('ajPushSetAlias')
          _this.ajPushSetAlias();
        }
      });
    } else {
      _this.ajPushSetAlias();
    }
  },
  ajPushSetAlias: function () {
    // 设置别名
    var _this = this;
    console.log("ajPushSetAlias");
    var userInfo = _this.userInfo;
    var param = { alias: userInfo.usSign + "", sequence: 101 };
    console.log("param" + JSON.stringify(param));
    ajpush.setAlias(param, function (ret) {
      console.log("------------------------------");
      console.log(JSON.stringify(ret));
      console.log("------------------------------");
    });
