AngularFire2将子节点数据检索为对象

我想使用angularfire2作为对象检索子节点中的数据

     getPostEditData(uid:any,key:any){

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

getPostEditData（uid:any，key:any）{
this.dataObject=this.af.database.object（'/webPosts/'+uid+key）作为
FirebaseObjectObservable
返回this.dataObject；}

我用过这个，但它不起作用。我该怎么做呢？

您需要另一个斜杠（

/

）和您的引用

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

getPostEditData（uid:any，key:any）{
this.dataObject=
此.af.database.object（'/webPosts/'+uid+'/'+key）作为FirebaseObjectObservable
返回此.dataObject；
}

错误：

uid+键

右：

uid+'/'+键

右键：

uid+'/'+键
