修改消息

修改已发送消息的内容并同步结果。

修改操作会替换已有消息内容并同步，与仅影响本机的更新或删除不同。

import sdk, {
  EventOnMessageEditedData,
  EventOnMessageModifiedData,
  IMMessage,
  ModifyMessageReq,
  ModifyMessageResp,
  OpenIMSDKEvent,
} from '@openimsdk/imsdk';

const editedMessage: IMMessage = cloneMessage(message);
if (editedMessage.textElem !== undefined) {
  editedMessage.textElem.content = editedText;
}
const request: ModifyMessageReq = {
  conversationID: conversationID,
  message: editedMessage,
};
const response: ModifyMessageResp = await sdk.modifyMessage(request);
replaceMessage(conversationID, response.message);

const handleMessageModified = (data: EventOnMessageModifiedData): void => {
  const targetConversationID = resolveMessageConversationID(data.message);
  replaceMessage(targetConversationID, data.message);
};
const unsubscribeMessageModified = sdk.on(
  OpenIMSDKEvent.EventOnMessageModified,
  handleMessageModified,
);

const handleMessageEdited = (data: EventOnMessageEditedData): void => {
  const targetConversationID = resolveMessageConversationID(data.message);
  replaceMessage(targetConversationID, data.message);
};
const unsubscribeMessageEdited = sdk.on(OpenIMSDKEvent.EventOnMessageEdited, handleMessageEdited);

export function removeMessageEditListeners(): void {
  unsubscribeMessageModified();
  unsubscribeMessageEdited();
}

修改对象必须保留原 clientMsgID 和其他必要字段。允许修改的发送者、时间窗口和消息类型由 OpenIMServer 校验。Promise 成功后可立即替换本地项；其他客户端通过事件更新。

EventOnMessageModified 和 EventOnMessageEdited 都携带最新的 IMMessage，应使用 conversationID 定位会话，再按 clientMsgID 替换消息。两个事件代表不同的底层编辑通知途径，不应假定 modifyMessage() 必然同时触发两者。销毁状态层时移除监听。
