useWebSocket

反应式 WebSocket 客户端。

¥Reactive WebSocket client.

用法

¥Usage

import { useWebSocket } from '@vueuse/core'

const { status, data, send, open, close } = useWebSocket('ws://websocketurl')

请参阅 类型声明 了解更多选项。

¥See the Type Declarations for more options.

immediate

默认启用。

¥Enable by default.

调用可组合函数时立即建立连接。

¥Establish the connection immediately when the composable is called.

autoConnect

默认启用。

¥Enable by default.

如果 url 作为 ref 提供，则当 url 发生更改时，它会自动重新连接到新的 url。

¥If url is provided as a ref, when the url changes, it will automatically reconnect to the new url.

autoClose

默认启用。

¥Enable by default.

当触发 beforeunload 事件或相关效果范围停止时，这将自动调用 close()。

¥This will call close() automatically when the beforeunload event is triggered or the associated effect scope is stopped.

autoReconnect

出现错误时自动重新连接（默认禁用）。

¥Reconnect on errors automatically (disabled by default).

const { status, data, close } = useWebSocket('ws://websocketurl', {
  autoReconnect: true,
})

或者对其行为进行更多控制：

¥Or with more controls over its behavior:

const { status, data, close } = useWebSocket('ws://websocketurl', {
  autoReconnect: {
    retries: 3,
    delay: 1000,
    onFailed() {
      alert('Failed to connect WebSocket after 3 retries')
    },
  },
})

显式调用 close() 不会触发自动重新连接。

¥Explicitly calling close() won't trigger the auto reconnection.

heartbeat

通常的做法是在每个给定时间过去后发送一条小消息（心跳）以保持连接处于活动状态。在此函数中，我们提供了一个方便的助手来完成此操作：

¥It's common practice to send a small message (heartbeat) for every given time passed to keep the connection active. In this function we provide a convenient helper to do it:

const { status, data, close } = useWebSocket('ws://websocketurl', {
  heartbeat: true,
})

或者使用更多控件：

¥Or with more controls:

const { status, data, close } = useWebSocket('ws://websocketurl', {
  heartbeat: {
    message: 'ping',
    interval: 1000,
    pongTimeout: 1000,
  },
})

子协议

¥Sub-protocols

要使用的一个或多个子协议的列表，在本例中为肥皂和 wamp。

¥List of one or more subprotocols to use, in this case soap and wamp.

const { status, data, send, open, close } = useWebSocket('ws://websocketurl', {
  protocols: ['soap'], // ['soap', 'wamp']
})
