监听ios消息，透传receive收不到内容

unipush使用了push_channel传参，传参内容：
{"request_id":"JhVLrhdfEpnTlxs","audience":{"cid":["724525331aa2cb7077404842e74e03a9"]},"push_message":{"notification":{"title":"test","body":"test1","click_type":"none"}},"push_channel":{"ios":{"type":"notify","aps":{"alert":{"title":"test","body":"test1"},"category":"ACTIONABLE"},"payload":"123123","auto_badge":"1"}}}
离线的情况下能收到通知
在线的情况下接听到了透传消息，但是内容是空的{"aps":null,"content":"","payload":"","title":"xxxx","type":"receive"}
aps和content都是空的，麻烦哪位能帮忙看下，谢谢
