MsgModifyMessage
功能介绍
消息变更
如果消息修改成功，自己和对端用户（C2C）或群组成员（Group）都会收到 MsgUpdateCallback 回调。
如果在修改消息过程中，消息已经被其他人修改，cb 会返回 ERR_SDK_MSG_MODIFY_CONFLICT 错误。
消息无论修改成功或则失败，cb 都会返回最新的消息对象。
参数详解
重载1
| 参数名称 | 参数类型 | 是否必填 | 描述 |
|---|---|---|---|
| message | Message | 是 | 消息体 |
| callback | ValueCallback< Message > | 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 |
|---|---|---|---|
| message | Message | 是 | 消息体 |
| 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:'' // json_params为空字符串""
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 |
