解析云 - 手动输入安装（推送通知）

Question

我正在使用Javascript SDK和Appccelerator Titanium。 Javascript SDK没有保存deviceToken以启用推送的功能。我尝试了各种方法，但应该工作的方法（不是）通过云功能保存。我做错了什么？

Parse.Cloud.define("subscribeToPush", function(request, response) {
    Parse.Cloud.useMasterKey();
    var Installation = Parse.Object.extend("Installation");
    var membership = new Installation();

    membership.set("deviceType", request.params.os);
    membership.set("deviceToken", request.params.deviceToken);
    membership.set("channels", ["general"]);
    membership.save(null,{
      success:function(membership) { 
        response.success(membership);
      },
      error:function(error) {
        response.error(error);
      }
    }); 
});

运行此功能后，Cloud Log显示它已创建，但我在数据浏览器中看不到它。
