AngularFire2 检索子节点数据作为对象

Question

我想使用 angularfire2 将子节点中的数据作为对象检索

     getPostEditData(uid:any,key:any){

     this.dataObject = this.af.database.object('/webPosts/'+uid+key) as 
     FirebaseObjectObservable<postVal>
     return this.dataObject; }

我用过这个，但它不起作用。我应该怎么做？ My Structure

Answer 1

您的参考资料还需要一个斜杠 (/)。

getPostEditData(uid:any,key:any) {
    this.dataObject = 
        this.af.database.object('/webPosts/' + uid + '/' + key) as FirebaseObjectObservable<postVal>
    return this.dataObject; 
}

错误：uid + key

右：uid + '/' + key
