Key Implementation Requirements

关键实现要求

Initialize Chat SDK

初始化Chat SDK

javascript
import { Chat } from '@pubnub/chat';

const chat = await Chat.init({
  publishKey: 'pub-c-...',
  subscribeKey: 'sub-c-...',
  userId: 'user-123',
  // For Access Manager: use authKey (not token)
  authKey: 'auth-token-from-server'
});
javascript
import { Chat } from '@pubnub/chat';

const chat = await Chat.init({
  publishKey: 'pub-c-...',
  subscribeKey: 'sub-c-...',
  userId: 'user-123',
  // 对于Access Manager：使用authKey（而非token）
  authKey: 'auth-token-from-server'
});

Create Direct Channel

创建一对一频道

javascript
const { channel } = await chat.createDirectConversation({
  user: interlocutor,  // The other user
  channelData: { name: 'Direct Chat' }
});
javascript
const { channel } = await chat.createDirectConversation({
  user: interlocutor,  // 对方用户
  channelData: { name: 'Direct Chat' }
});

Send and Receive Messages

发送与接收消息

javascript
// Connect to receive messages
channel.connect((message) => {
  console.log('Received:', message.text);
});

// Send message
await channel.sendText('Hello!');
javascript
// 连接以接收消息
channel.connect((message) => {
  console.log('Received:', message.text);
});

// 发送消息
await channel.sendText('Hello!');

Constraints

约束条件

  • Use 
    authKey
    (not 
    token
    ) for Access Manager authentication
  • Explicitly create/retrieve users before conversations
  • Cache channels to avoid recreating on each load
  • Clean up subscriptions on logout/unmount
  • userId must be persistent and unique per user
  • 对于Access Manager认证，使用
    authKey
    （而非
    token
    ）
  • 在创建对话前需显式创建/获取用户
  • 缓存频道以避免每次加载时重复创建
  • 在登出/卸载时清理订阅
  • userId必须持久且每个用户唯一
