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。
截图：
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">

<style>
body {

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 URL
socket = 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>
</body>
</html>
