无法使用REST API过滤Firebase模型

Question

我正在尝试使用Firebase的REST API仅检索具有特定Podcast API的剧集。 curl请求返回数据库中的所有剧集，而不仅仅是podcastID =“863897795”

的剧集。

这是我尝试的第一个查询：

curl https://myurl.firebaseio.com/episodes.json?orderBy=\"podcastID\"&equalTo="863897795"

这是第二个：

curl https://myurl.firebaseio.com/episodes.json?orderBy=\"podcastID\"&endAt="863897795"&startAt="863897795"

这是我的模特：
