更​​新：事实证明，这是一个权限问题。我试图访问我没有作用域的数据源，但事实上，在主机***问时，它没有返回403把我摔下的踪迹。仍然奇怪的是，它没有返回403当主机服务器上的请求，虽然......如果你看到这一点，有一个想法，为什么，随意评论（它只是返回一个空的JSON对象）。我很好奇。

Update: This turned out to be a permissions issue. I was trying to access a data source that I didn't have scopes for, the fact that it didn't return a 403 when accessing on the host threw me off the trail. Still strange that it didn't return a 403 (it just returned an empty json object) when requested on the host server though...if you see this and have an idea why, feel free to comment. I'm curious.
