鸿蒙开发融云IMKit初始化和登录

融云鸿蒙版是不带UI的，得自己一步步搭建。
下面说如何初始化和登录：

一、初始化：

/*** @desc : 初始化融云* @author : congge on 2024-07-12 15:47**/public  static  initRongIm() {IMEngine.getInstance().init(getContext(), CommonConstants.RONG_IM_KEY, new InitOption())// 注册自定义消息let clazzList: List<MessageContentConstructor> = new List()clazzList.add(CustomizeReadReceiptMessage)clazzList.add(CustomizeGiftMessage)IMEngine.getInstance().registerMessageType(clazzList)// 监听消息接收IMEngine.getInstance().setMessageReceivedListener((message: Message, _info: ReceivedInfo) => {logContent("receivedMessage",message)if (message.content) {if (message.objectName === HQVoiceMessageObjectName && message.direction === MessageDirection.Receive && !_info.isOffline) {// isOffline为true,是卸载重装收到的消息不用管，正常刚收到的语音消息全部是未点击，它不可能一收到就点击了的MMKVNoClearUtil.saveVoiceMessageReadStatus(message.targetId,message.messageId,false)}// 在这就不发已读回执了，避免两个鸿蒙一直在互发已读// if (MMKVUtil.getCurrentChatTargetId(message.targetId) === message.targetId) {//   ImUtils.sendMyReadReceiptMessage(message.targetId,message.sentTime)// } else if(MainPage.homeTabSelected === 3){//   ImUtils.sendMyReadReceiptMessage(message.targetId,message.sentTime)// }// 刷新首页未读数EventKeys.postEvent(EventKeys.MsgRedEvents,MsgRedEvent())// 刷新会话列表，不打算自己插入会话EventKeys.postEvent(EventKeys.RefreshMsgListEvents)}// 接收到单聊消息，发送到聊天界面if (message.conversationType === ConversationType.Private || message.targetId === ImType.KEFU_ID) {EventKeys.postEvent(EventKeys.ReceivedImMessageEvents,ReceivedImMessageEvent(message))}});}

二、登录：

public static connectIm() {if (MMKVUtil.getImToken()) {ImUtils.realConnect(MMKVUtil.getImToken());} else {//正常只有第一次进入应用会为""ImViewModel.postImToken(false, (result) => {ImUtils.realConnect(result.token)})}}private static realConnect(token?: string, isAgain: boolean = false) {if (token) {IMEngine.getInstance().setConnectionStatusListener((status: ConnectionStatus) => {logContent('IM-App', 'setConnectionStatusListener onChanged status:' + status);if (status === ConnectionStatus.DisconnectUserKicked) {showToast($r('app.string.account_notice_tick'));// 特别注意：对方登录，强迫退出// Router.pushGuidePage(true)}});// timeout ≦ 0，IM 将一直连接，直到连接成功或者发生无法连接的业务错误（如 token 非法）IMEngine.getInstance().connect(token, 0).then(result => {if (EngineError.Success === result.code) {// 连接成功MMKVUtil.saveTargetId(result.userId)EventKeys.postEvent(EventKeys.MsgRedEvents,MsgRedEvent())logContent("imStatus", "成功token: " + token)logContent("imStatus", "成功targetId: " + result.userId)//let userId = result.userId;return;}if (EngineError.ConnectTokenExpired === result.code) {// Token 过期，从 APP 服务请求新 token，获取到新 token 后重新 connect()} else if (EngineError.ConnectionTimeout === result.code) {// 连接超时，弹出提示，可以引导用户等待网络正常的时候再次点击进行连接showToast($r('app.string.net_error'))} else {//其它业务错误码，请根据相应的错误码作出对应处理。logContent("imStatus", result.code)}});}}
