方法1: 使用 websocket 库 websocket 是一个常用的库,简化了 WebSocket 通信的实现。首先,确保安装该库: npm install websocket 然后,在 React 组件中使用: import{ useEffect }from'react';importWebSocketfrom'websocket';constMyComponent= () => {useEf
Components can close/unsubscribe from a WebSocket by passing false as the third parameter. This provides a more explicit solution than the previous method of setting the socketUrl to null. Both methods work and are supported usage. Example Implementation import React, { useState, useCallback, useE...
react-use-websocket是一个React Hook,用于在React应用中轻松地使用WebSocket。它提供了一系列的功能,如发送消息、接收消息、处理连接状态等。为了处理超时,我们需要监听连接状态,并在连接失败时尝试重新连接。 2. 编写代码以处理WebSocket连接超时事件 首先,我们需要使用useWebSocket Hook来创建一个WebSocket连接。然后,我们...
importuseWebSocketfrom'react-native-use-websocket';// In functional React component// This can also be an async getter function.

import React, { useState, useCallback, useEffect } from 'react'; import useWebSocket, { ReadyState } from 'react-use-websocket'; export const WebSocketDemo = () => { //Public API that will echo messages sent to it back to the client const [socketUrl, setSocketUrl] = useState('wss:...
npm install --save react-use-websocket@3.0.0 //or yarn add react-use-websocket@3.0.0 New in 2.0.0 useWebSocketnow returns an object instead of an array. This allows you to pick out specific features/properties to suit your use-case as well as removing mental overhead of keeping track ...
在React中使用Custom Hooks来封装和管理WebSocket连接非常方便和灵活。下面是一个简单的示例让您了解如何实现: 首先,创建一个名为useWebSocket的Custom Hook: import{ useState, useEffect }from'react';constuseWebSocket= (url) => {const[socket, setSocket] =useState(null);useEffect(() =>{constnewSocket =ne...
当组件挂载时，第二个useEffect钩子只运行一次，您将在回调范围内记录关闭的初始operationsList状态值。换...

react-use-websocket是一个react hook,用于在react应用程序中处理websocket连接。它接受两个参数:url和options。其中,options参数是一个可选的对象,可以包含一些配置选项,如shouldconnect。 shouldconnect是一个布尔值,默认为true。它决定了websocket连接是否应该自动建立。如果shouldconnect设置为true,则当组件挂载时,websocke...
