前端代码实现：

<!DOCTYPE html>
<html>
<head>
<title>Hello, World!</title>
</head>
<body>
<p type="text" id="myInput"></p>

</body>
<script>
// 创建一个 XMLHttpRequest 对象
var xhr = new XMLHttpRequest();

// 设置请求的 URL
xhr.open('GET', 'http://10.64.153.130:19000/get');

// 设置请求头，包括 Content-Type 和 Accept 等信息
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.setRequestHeader('Accept', 'application/json');
xhr.setRequestHeader('Access-Control-Allow-Origin', '*');

// 发送请求并获取响应
xhr.onload = function() {
if (xhr.status === 200) {
// 获取响应数据
// var data = JSON.parse(xhr.responseText);
var data=xhr.responseText;

// 将数据绑定到 DOM 元素上
document.getElementById('myInput').innerHTML = data;
navigator.clipboard.writeText(data).then(() => {
console.log('文本已复制到剪切板');
}).catch(() => {
console.error('无法复制文本到剪切板');
});
// document.getElementById('myInput').innerHTML = data.age + '岁';
} else {
console.log('There was a problem with the fetch request.');
}
};

// 发送请求
xhr.send();
</script>
</html>
