Retrieve pending reminders for a specific channel and process them based on their type. This example shows how to filter for mentions and join requests.

```typescript
// 获取指定频道的待处理提醒
const channel = new Channel('group123', 2);
const channelReminders = sdk.reminderManager.getWaitDoneReminders(channel);
channelReminders.forEach(reminder => {
    if (reminder.reminderType === ReminderType.ReminderTypeMentionMe) {
        console.log('有人@我:', reminder.text);
    } else if (reminder.reminderType === ReminderType.ReminderTypeApplyJoinGroup) {
        console.log('入群申请:', reminder.data);
    }
});
```

--------------------------------

### Get Channel Subscribers List

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Retrieve the list of subscribers for a given channel from the SDK's cache. This provides access to member details like UID, name, and role.

```typescript
const subscribers = sdk.channelManager.getSubscribes(channel);
subscribers.forEach(sub => {
    console.log('成员:', sub.uid, sub.name, '角色:', sub.role);
});
```

--------------------------------

### Fetch and Get Channel Information

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Retrieve channel information from the cache. If not found, it triggers an asynchronous fetch operation. Ensure the channel object is correctly instantiated with its ID and type.

```typescript
const channel = new Channel('group123', ChannelTypeGroup);
let channelInfo = sdk.channelManager.getChannelInfo(channel);
if (!channelInfo) {
    // 触发异步获取
    await sdk.channelManager.fetchChannelInfo(channel);
    channelInfo = sdk.channelManager.getChannelInfo(channel);
}
```

--------------------------------

### Get Own Subscriber Information

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Retrieve your own information within a specific channel, including your role. Returns null if you are not a member of the channel.

```typescript
const myInfo = sdk.channelManager.getSubscribeOfMe(channel);
if (myInfo) {
    console.log('我的角色:', myInfo.role);
}
```

--------------------------------

### Initialize and Configure SDK

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Configure the singleton instance with server addresses, authentication tokens, and data provider callbacks for channel info and message synchronization.

// 获取 SDK 单例
const sdk = WKSDK.shared();

// 基础配置
sdk.config.addr = 'ws://your-wukongim-server:5200/ws'; // IM 服务器地址
sdk.config.uid = 'user123';  // 当前用户 UID
sdk.config.token = 'your-auth-token';  // 认证 token
sdk.config.deviceFlag = 1;  // 设备标识: 0-app, 1-web, 2-pc
sdk.config.heartbeatInterval = 60000;  // 心跳间隔（毫秒）
sdk.config.debug = true;  // 开启调试模式

// 配置动态获取连接地址（可选）
sdk.config.provider.connectAddrCallback = (callback) => {
    // 从业务服务器获取 IM 连接地址
    fetch('/api/im/address').then(res => res.json()).then(data => {
        callback(data.wsAddr);
    });
};

// 配置频道信息获取回调

    channelInfo.mute = false;  // 是否免打扰
    channelInfo.top = false;   // 是否置顶
    channelInfo.orgData = {};  // 自定义业务数据

    return channelInfo;
};

// 配置消息同步回调
sdk.config.provider.syncMessagesCallback = async (channel: Channel, opts: SyncOptions): Promise<Message[]> => {
    const resp = await fetch('/api/messages/sync', {
        method: 'POST',
        body: JSON.stringify({

    console.log('消息序号:', sendack.messageSeq);
    console.log('原因码:', sendack.reasonCode);  // 1-成功
};
sdk.chatManager.addMessageStatusListener(statusListener);

// 同步历史消息
import { SyncOptions, PullMode } from 'wukongimjssdk';
const syncOpts = new SyncOptions();
syncOpts.startMessageSeq = 0;      // 起始消息序号
syncOpts.endMessageSeq = 0;        // 结束消息序号（0表示不限制）
syncOpts.limit = 30;               // 每次拉取数量
syncOpts.pullMode = PullMode.Down; // 向下拉取

const messages = await sdk.chatManager.syncMessages(personChannel, syncOpts);
console.log('同步到消息数量:', messages.length);

// 移除监听器

const conversationListener = (conversation: Conversation, action: ConversationAction) => {
    switch (action) {
        case ConversationAction.add:
            console.log('新增会话:', conversation.channel.channelID);
            break;
        case ConversationAction.update:
            console.log('会话更新:', conversation.channel.channelID);
            break;
        case ConversationAction.remove:
            console.log('会话删除:', conversation.channel.channelID);
            break;
    }

    console.log('未读数:', conversation.unread);
    console.log('最后一条消息:', conversation.lastMessage?.content);
    console.log('时间戳:', conversation.timestamp);
    console.log('是否有人@我:', conversation.isMentionMe);
    console.log('频道信息:', conversation.channelInfo);  // 自动获取缓存
};

// 获取所有会话
const allConversations = sdk.conversationManager.conversations;

// 查找特定会话
const targetChannel = new Channel('user456', 1);
const conversation = sdk.conversationManager.findConversation(targetChannel);
if (conversation) {
    console.log('找到会话，未读数:', conversation.unread);
}

// 查找多个会话
const channels = [new Channel('user1', 1), new Channel('user2', 1)];
const foundConversations = sdk.conversationManager.findConversations(channels);

// 创建空会话（用于主动发起聊天）
const newConversation = sdk.conversationManager.createEmptyConversation(
    new Channel('newUser', 1)
);

// 设置当前打开的会话（收到该会话消息时不增加未读数）
sdk.conversationManager.openConversation = conversation;

// 删除会话
sdk.conversationManager.removeConversation(targetChannel);

// 获取所有未读总数
const totalUnread = sdk.conversationManager.getAllUnreadCount();
console.log('总未读数:', totalUnread);

// 同步会话扩展信息（如草稿、浏览进度等）
const extras = await sdk.conversationManager.syncExtra();

// 设置不更新会话的消息类型（如系统消息）
sdk.conversationManager.addNoUpdateContentType(1000);  // 系统消息类型
sdk.conversationManager.removeNoUpdateContentType(1000);

// 移除监听器
sdk.conversationManager.removeConversationListener(conversationListener);
```

### Configure Reminder Synchronization Callback

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Set up a callback to synchronize reminders from a server. This function fetches reminder data based on a version number and maps it to Reminder objects. Ensure your API endpoint `/api/reminders/sync` is correctly implemented.

```typescript
import { WKSDK, Channel, Reminder, ReminderType } from 'wukongimjssdk';

const sdk = WKSDK.shared();

// 配置提醒同步回调
sdk.config.provider.syncRemindersCallback = async (version: number): Promise<Reminder[]> => {
    const resp = await fetch(`/api/reminders/sync?version=${version}`).then(r => r.json());

    return resp.map(item => {
        const reminder = new Reminder();
        reminder.reminderID = item.reminder_id;
        reminder.channel = new Channel(item.channel_id, item.channel_type);
        reminder.messageID = item.message_id;
        reminder.messageSeq = item.message_seq;
        reminder.reminderType = item.type;  // 1-@我, 2-入群申请
        reminder.text = item.text;
        reminder.data = item.data;
        reminder.isLocate = item.is_locate;  // 是否需要定位到消息
        reminder.version = item.version;
        reminder.done = item.done;
        return reminder;
    });
};
```

--------------------------------

### Configure Reminder Done Callback

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Implement a callback to mark reminders as completed on the server. This function sends a POST request with an array of reminder IDs to the `/api/reminders/done` endpoint.

```typescript
// 配置提醒完成回调
sdk.config.provider.reminderDoneCallback = async (ids: number[]): Promise<void> => {
    await fetch('/api/reminders/done', {
        method: 'POST',
        body: JSON.stringify({ reminder_ids: ids })
    });
};
```

--------------------------------

### Subscribe to Channel via String URL

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Subscribe to a channel using its string representation, which can include URL parameters. This is an alternative way to initiate a subscription.

```typescript
sdk.onSubscribe('channel123?param1=value1&param2=value2', (msg, reasonCode) => {
    console.log('订阅回调:', reasonCode);
});
```

--------------------------------

### Configure Subscriber Sync Callback

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Set up a callback to synchronize channel subscribers. This function is invoked when subscriber data needs to be updated, fetching the latest subscriber information from an API.

```typescript
sdk.config.provider.syncSubscribersCallback = async (channel: Channel, version: number): Promise<Subscriber[]> => {
    const resp = await fetch(`/api/channels/${channel.channelID}/subscribers?version=${version}`)
        .then(r => r.json());

    return resp.map(item => {
        const subscriber = new Subscriber();
        subscriber.uid = item.uid;
        subscriber.name = item.name;
        subscriber.avatar = item.avatar;
        subscriber.role = item.role;  // 角色：0-普通成员, 1-管理员, 2-群主
        subscriber.version = item.version;
        subscriber.isDeleted = item.is_deleted;
        subscriber.channel = channel;
        return subscriber;
    });
};
```

--------------------------------

### Manage WebSocket Connections

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Handle connection lifecycle events, monitor network latency, and control connection state using the connectManager.

```typescript
import { WKSDK, ConnectStatus } from 'wukongimjssdk';

const sdk = WKSDK.shared();

// 添加连接状态监听器
const statusListener = (status: ConnectStatus, reasonCode?: number) => {
    switch (status) {
        case ConnectStatus.Connected:
            console.log('连接成功');
            break;
        case ConnectStatus.Connecting:
            console.log('连接中...');
            break;
        case ConnectStatus.Disconnect:
            console.log('连接断开');
            break;
        case ConnectStatus.ConnectFail:
            console.log('连接失败，错误码:', reasonCode);
            // reasonCode: 2-认证失败, 3-订阅者不存在 等
            break;
        case ConnectStatus.ConnectKick:
            console.log('被踢下线（账号在其他地方登录）');
            break;
    }
};
sdk.connectManager.addConnectStatusListener(statusListener);

// 添加连接延迟监听（监控网络质量）
const delayListener = (delay: number) => {
    if (delay > 1000) {
        console.log('网络延迟较高:', delay, 'ms');
    }
    if (delay === 9999) {
        console.log('连接超时');
    }
};
sdk.connectManager.addConnectDelayListener(delayListener);

// 建立连接
sdk.connect();

// 判断是否已连接
if (sdk.connectManager.connected()) {
    console.log('当前已连接');
}

// 断开连接（不再自动重连）
sdk.disconnect();

// 移除监听器
sdk.connectManager.removeConnectStatusListener(statusListener);
sdk.connectManager.removeConnectDelayListener(delayListener);
```

--------------------------------

### Add Channel Info Change Listener

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Register a listener to receive updates on channel information changes, such as title, logo, mute status, and online presence.

```typescript
const channelInfoListener = (channelInfo: ChannelInfo) => {
    console.log('频道信息更新:', channelInfo.channel.channelID);
    console.log('标题:', channelInfo.title);
    console.log('头像:', channelInfo.logo);
    console.log('免打扰:', channelInfo.mute);
    console.log('置顶:', channelInfo.top);
    console.log('在线状态:', channelInfo.online);
};
sdk.channelManager.addListener(channelInfoListener);
```

--------------------------------

### Configure and Manage Message Read Receipts in TypeScript

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Utilize the receiptManager to handle message read receipts efficiently. Configure callbacks for read status, add listeners for receipt events, and manage messages that require read receipts. The SDK automatically batches and sends receipts at configured intervals.

```typescript
import { WKSDK, Channel, Message } from 'wukongimjssdk';

const sdk = WKSDK.shared();

// 配置消息已读回调
sdk.config.provider.messageReadedCallback = async (channel: Channel, messages: Message[]): Promise<void> => {
    const messageIds = messages.map(m => m.messageID);
    await fetch('/api/messages/read', {
        method: 'POST',
        body: JSON.stringify({
            channel_id: channel.channelID,
            channel_type: channel.channelType,
            message_ids: messageIds
        })
    });
};

// 添加已读回执监听
const receiptListener = (channel: Channel, messages: Message[]) => {
    console.log('已读回执发送成功:', channel.channelID, '消息数:', messages.length);
    messages.forEach(msg => {
        msg.remoteExtra.readed = true;
        msg.remoteExtra.readedAt = new Date();
    });
};
sdk.receiptManager.addListener(receiptListener);

// 添加需要发送已读回执的消息
const channel = new Channel('user123', 1);
const unreadMessages = getUnreadMessages();  // 获取未读消息列表
sdk.receiptManager.addReceiptMessages(channel, unreadMessages);
// SDK 会自动定时批量发送已读回执

// 配置回执发送间隔（在初始化时设置）
sdk.config.receiptFlushInterval = 2000;  // 2秒间隔

// 移除监听器
sdk.receiptManager.removeListener(receiptListener);
```

--------------------------------

### Mark Reminders as Done

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Mark a list of reminders as completed by calling the `done` method on the reminder manager with an array of reminder IDs.

```typescript
// 标记提醒为已完成
const reminderIds = [1, 2, 3];
await sdk.reminderManager.done(reminderIds);
```

--------------------------------

### Sync and Retrieve Reminders

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Manually trigger a reminder synchronization and access all available reminders. The `sync()` method should typically be called after session synchronization. Retrieved reminders are stored in `sdk.reminderManager.reminders`.

```typescript
// 同步提醒（通常在会话同步后自动调用）
await sdk.reminderManager.sync();

// 获取所有提醒
const allReminders = sdk.reminderManager.reminders;
console.log('提醒数量:', allReminders.length);
```

--------------------------------

### Subscribe to Channel Real-time Data

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Subscribe to a channel to receive real-time messages and updates. Allows passing custom parameters via subscribeConfig.

```typescript
sdk.onSubscribe(channel, (msg, reasonCode) => {
    if (reasonCode === ReasonCode.success) {
        console.log('订阅成功');
    }
    if (msg) {
        console.log('收到订阅消息:', msg);
    }
}, subscribeConfig.withParam({ key: 'value' }));
```

--------------------------------

### Manually Set Channel Information Cache

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Manually update the channel information cache with new details like title and logo. This is useful for immediate updates before the SDK fetches them.

```typescript
const newInfo = new ChannelInfo();
newInfo.channel = channel;
newInfo.title = '新群名称';
newInfo.logo = 'https://example.com/avatar.png';
sdk.channelManager.setChannleInfoForCache(newInfo);
```

--------------------------------

### Synchronize Channel Subscribers

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Manually trigger the synchronization of channel subscribers. This ensures the local cache has the latest member list.

```typescript
await sdk.channelManager.syncSubscribes(channel);
```

--------------------------------

### Access Reminders via Conversation

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Retrieve reminders associated with a specific conversation. This includes accessing simplified reminders (deduplicated by type) and all reminders for that conversation.

```typescript
// 通过会话获取提醒
const conversation = sdk.conversationManager.findConversation(channel);
if (conversation) {
    // 获取去重后的提醒（按类型去重）
    const simpleReminders = conversation.simpleReminders;
    // 获取所有提醒
    const allConvReminders = conversation.reminders;
}
```

--------------------------------

### Define Custom Message Types in TypeScript

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Extend MessageContent or MediaMessageContent to create custom message types. Define content types, conversation digests, and methods for encoding/decoding JSON data. Ensure custom content types are registered with the SDK.

```typescript
import { WKSDK, MessageContent, MediaMessageContent, MessageContentType } from 'wukongimjssdk';

// 定义自定义消息类型常量
const CustomContentType = {
    location: 3,      // 位置消息
    voice: 4,         // 语音消息
    video: 5,         // 视频消息
    card: 6,          // 名片消息
    redPacket: 100,   // 红包消息
};

// 自定义位置消息
class LocationContent extends MessageContent {
    latitude: number = 0;
    longitude: number = 0;
    address: string = '';

    get contentType(): number {
        return CustomContentType.location;
    }

    get conversationDigest(): string {
        return '[位置]';
    }

    // 解码服务端返回的数据
    decodeJSON(content: any): void {
        this.latitude = content.latitude || 0;
        this.longitude = content.longitude || 0;
        this.address = content.address || '';
    }

    // 编码发送给服务端的数据
    encodeJSON(): any {
        return {
            latitude: this.latitude,
            longitude: this.longitude,
            address: this.address
        };
    }
}

// 自定义语音消息（带附件）
class VoiceContent extends MediaMessageContent {
    duration: number = 0;  // 时长（秒）
    waveform: number[] = [];  // 波形数据

    constructor(file?: File, duration?: number) {
        super();
        this.file = file;
        this.duration = duration || 0;
    }

    get contentType(): number {
        return CustomContentType.voice;
    }

    get conversationDigest(): string {
        return `[语音] ${this.duration}秒`;
    }

    decodeJSON(content: any): void {
        this.duration = content.duration || 0;
        this.remoteUrl = content.url || '';
        this.waveform = content.waveform || [];
    }

    encodeJSON(): any {
        return {
            duration: this.duration,
            url: this.remoteUrl,
            waveform: this.waveform
        };
    }
}

// 注册自定义消息类型
const sdk = WKSDK.shared();
sdk.register(CustomContentType.location, () => new LocationContent());
sdk.register(CustomContentType.voice, () => new VoiceContent());

// 注册消息类型工厂（处理一类消息）
sdk.registerFactor((contentType: number) => {
    // 处理 1000-2000 范围的系统消息
    if (contentType >= 1000 && contentType <= 2000) {
        return new SystemNoticeContent();  // 自定义系统通知类
    }
    return undefined;
});

// 发送位置消息
const location = new LocationContent();
location.latitude = 39.9042;
location.longitude = 116.4074;
location.address = '北京市天安门广场';
await sdk.chatManager.send(location, channel);

// 发送语音消息
const audioFile = getAudioFile();  // 获取音频文件
const voice = new VoiceContent(audioFile, 10);  // 10秒语音
await sdk.chatManager.send(voice, channel);

// 获取消息内容实例
const content = sdk.getMessageContent(CustomContentType.location);
```

--------------------------------

### Unsubscribe from Channel

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Cancel the subscription to a channel, stopping real-time message delivery. The callback provides the reason code for the unsubscribe operation.

```typescript
sdk.onUnsubscribe(channel, (reasonCode) => {
    console.log('取消订阅结果:', reasonCode);
});
```

--------------------------------

### Add and Remove Event Listeners

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Register a listener function to receive real-time events from the SDK and unregister it when no longer needed. The listener processes various event types, including streaming messages.

```typescript
import { WKSDK, WKEvent, EventType } from 'wukongimjssdk';

const sdk = WKSDK.shared();

// 添加事件监听器
const eventListener = (event: WKEvent) => {
    console.log('收到事件:', event.type);
    console.log('事件ID:', event.id);
    console.log('时间戳:', event.timestamp);
    console.log('数据:', event.dataJson);

    // 处理流式文本消息事件
    switch (event.type) {
        case EventType.TextMessageStart:
            console.log('流式消息开始');
            break;
        case EventType.TextMessageContent:
            console.log('流式消息追加:', event.dataJson.content);
            break;
        case EventType.TextMessageEnd:
            console.log('流式消息结束');
            break;
        default:
            // 处理自定义事件
            handleCustomEvent(event);
    }
};
sdk.eventManager.addEventListener(eventListener);

// 移除事件监听器
sdk.eventManager.removeEventListener(eventListener);
```

--------------------------------

### Handle Custom Server-Sent Events

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Process custom events pushed from the server, such as user typing indicators, online/offline status changes, or other application-specific notifications. This function demonstrates a switch statement for different custom event types.

```typescript
// 自定义事件处理示例
function handleCustomEvent(event: WKEvent) {
    const data = event.dataJson;

    switch (event.type) {
        case 'user_typing':
            console.log('用户正在输入:', data.uid);
            break;
        case 'user_online':
            console.log('用户上线:', data.uid);
            break;
        case 'user_offline':
            console.log('用户离线:', data.uid);
            break;
    }
}
```

--------------------------------

### Add Channel Member Change Listener

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Add a listener to be notified when the members of a channel change. This callback logs the channel ID and the current number of members.

```typescript
const subscriberListener = (channel: Channel) => {
    console.log('频道成员变更:', channel.channelID);
    const members = sdk.channelManager.getSubscribes(channel);
    console.log('当前成员数:', members.length);
};
sdk.channelManager.addSubscriberChangeListener(subscriberListener);
```

--------------------------------

### Delete Channel Information from Cache

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Remove a specific channel's information from the SDK's cache. This can be useful for clearing outdated data.

```typescript
const deletedInfo = sdk.channelManager.deleteChannelInfo(channel);
```

--------------------------------

### Remove Listeners

Source: https://context7.com/wukongim/wukongimjssdk/llms.txt

Deregister previously added listeners for channel information changes and subscriber changes to stop receiving updates.

```typescript
sdk.channelManager.removeListener(channelInfoListener);
sdk.channelManager.removeSubscriberChangeListener(subscriberListener);
```
