不能發送解析推送通知

我已解析了一段時間，它工作正常。現在我面臨發送推送通知的問題。這我已經完成不能發送解析推送通知

curl -X POST \ 
    -H "X-Parse-Application-Id: application id" \ 
    -H "X-Parse-REST-API-Key: REST_API_KEY" \ 
    -H "Content-Type: application/json" \ 
    -d '{ 
     "channels":[''], 
     "data": { 
      "alert": "The Giants won against the Mets 2-3." 
     } 
     }' \ 
    https://api.parse.com/1/push

我打算髮送廣播消息。但在解析控制檯它顯示

Targeting : 
channels includes any of , or nil 
deviceType is any of "android", "winphone", or "js" 
Sending date : 
November 26th, 2013 at 4:32 PM 
Expiration : 
None 
Full target : 
{ "channels": { "$in": [ ] }, "deviceType": { "$in": [ "android", "winphone", "js" ] } } 
Full data : 
{ "alert": "The Giants won against the Mets 2-3." }

蔭無法從哪裏是關鍵「在$」是被指定爲全目標人物？使用解析控制檯發送推送工作正常。

如何解決？
