龙岩app定制百度seo网站优化 网络服务
背景：
后端写好websocket 接口后，用postman的某些版本无法直接模拟websocket请求，所以想着自制一个小工具。
使用方法：
直接复制以下代码到文本文件中，修改服务端端地址，保存为 .html的后缀名，用浏览器打开即可直接使用。

代码如下：
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>WebSocket Client</title><style>body {font-family: Arial, sans-serif;margin: 20px;}#messages {width: 400px;height: 300px;border: 1px solid #ccc;overflow-y: scroll;padding: 10px;margin-bottom: 10px;}input[type="text"] {width: 300px;padding: 5px;}button {padding: 5px 10px;}</style>
</head>
<body><h1>WebSocket Client</h1><div id="messages"></div><input type="text" id="messageInput" placeholder="Type a message..."><button onclick="sendMessage()">Send</button><script>let socket;function connect() {// Replace 'ws://example.com/socket' with your WebSocket server URLsocket = new WebSocket('ws://localhost:8088/ws?token=333opqrst');socket.onopen = () => {console.log('Connected to WebSocket server');};socket.onmessage = (event) => {const messagesDiv = document.getElementById('messages');const messageElement = document.createElement('div');messageElement.textContent = `B: ${event.data}`;messagesDiv.appendChild(messageElement);};socket.onclose = () => {console.log('Disconnected from WebSocket server');};}function sendMessage() {if (!socket || socket.readyState !== WebSocket.OPEN) {alert('Not connected to the WebSocket server.');return;}const messageInput = document.getElementById('messageInput');const message = messageInput.value;socket.send(message);const messagesDiv = document.getElementById('messages');const messageElement = document.createElement('div');messageElement.textContent = `A: ${message}`;messagesDiv.appendChild(messageElement);messageInput.value = '';}window.onload = connect;</script>
