java - 极光推送怎么判断用户在线状态
可以直接推送消息，但是判断是否在线抛异常：
Got error response - responseCode:403, responseContent:{"error":{"code":2004,"message":"Need permission to perform this action."}}
Request is forbidden! Maybe your appkey is listed in blacklist or your params is invalid.
调用的方法：
public Map<String,OnlineStatus> getUserOnlineStatus(String... registrationIds)
throws cn.jiguang.common.resp.APIConnectionException,
cn.jiguang.common.resp.APIRequestException
