Google Firebase OrderByChild无法使用嵌套动态键

Question

当动态键介于实际参考和数据之间时，按子（名称）排序不起作用。

这是我的代码：

firebase.database().ref('/usersProfile').orderByChild('name').on('value', function(snapshot) {
  callback(snapshot);
});

callback(snapshot) {
  //console.log(snapshot);
  let data = snapshot.val();
  self.users = [];
  for(let key in data) {
    let value = data[key];
    value.categId = key;
    self.users.push(value);
  }
}

这是我通过服务器收集的数据：

我认为你的正斜线可能是问题所在。它应该看起来像这样：
