发送消息 参数
id 消息唯一标识
receiver 消息接收者的 userID, 如果是发送 C2C 单聊消息,只需要指定 receiver 即可。
groupID 目标群组 ID,如果是发送群聊消息,只需要指定 groupID 即可。
priority 消息优先级,仅针对群聊消息有效。请把重要消息设置为高优先级(比如红包、礼物消息),高频且不重要的消息设置为低优先级(比如点赞消息)。
onlineUserOnly 是否只有在线用户才能收到,如果设置为 true ,接收方历史消息拉取不到,常被用于实现“对方正在输入”或群组里的非重要提示等弱提示功能,该字段不支持 AVChatRoom。
offlinePushInfo 离线推送时携带的标题和内容。
needReadReceipt 消息是否需要已读回执(只有 Group 消息有效,6.1 及以上版本支持,需要您购买旗舰版套餐)
