MsgGetMessageReadReceipts

功能介绍

获取消息已读回执

msg_array 里的消息必须在同一个会话中。

发送端从其他界面进入消息列表后，先拉取历史消息，再调用 MsgGetMessageReadReceipts 接口拉取消息已读回执信息。

该功能需要购买旗舰版套餐包，购买旗舰版套餐包后可使用。

参数详解

重载1

参数名称	参数类型	是否必填	描述
msg_array	List< Message >	是	消息列表
callback	ValueCallback< List< MessageReceipt > >	是	异步回调返回值的json_param的格式为json

重载2

参数名称	参数类型	是否必填	描述
msg_array	List< Message >	是	消息列表
callback	ValueCallback< string >	是	异步回调返回值的json_param的格式为string

返回模板

TIMResult

调用成功后回调函数参数：
code:int
desc:string
json_param:List<MessageReceipt>
user_data:string

返回值详解

名称	数值类型	描述
TIMResult	TIMResult	调用接口的返回值
code	int	值为ERR_SUCC表示成功，其他值表示失败。详情请参考错误码
desc	string	错误描述字符串
json_param	string	Json字符串，不同的接口，Json字符串不一样
user_data	string	ImSDK负责透传的用户自定义数据，未做任何处理
