环境配置
我们需要配置城市中的城市元素,包括道路、建筑、树木、交通、商店、医院等，这些元素将帮助构建一个真实感更强的虚拟城市。

VPN 设置界面
我们需要设计一个用户可以设置VPN连接的界面。
<!DOCTYPE html>
<html>
<head>城市VPN设置</title>
<style>
.container {
max-width: 12px;
margin: 0 auto;
padding: 2px;
}
.input-group {
margin-bottom: 2px;
}
.input-group label {
display: block;
margin-bottom: 1px;
}
.input-group input {
width: 1%;
padding: 8px;
border: 1px solid #ddd;
border-radius: 4px;
}
.btn {
background-color: #;
color: white;
padding: 1px 2px;
border: none;
border-radius: 4px;
cursor: pointer;
}
.btn:hover {
background-color: #;
color: white;
box-shadow: 0 2px 4px rgba(,,,.1);
}
</style>
</head>
<body>
<div class="container">
<h1>城市VPN设置</h1>
<div class="input-group">
<label for="ip">网络IP地址：</label>
<input type="text" id="ip" placeholder="192.168.1.1">
</div>
<div class="input-group">
<label for="port">隐私VPN端口：</label>
<input type="text" id="port" placeholder="8">
</div>
<div class="input-group">
<label for="password">密码：</label>
<input type="password" id="password" placeholder="123456">
</div>
<button onclick="setVPN()">设置</button>
</div>
</body>
</html>
VPN 实现
我们需要实现VPN功能,以下是一个基本的VPN协议（如H2VPN）示例。
const { createWindow } = Window;
const canvas = createCanvas(4, 4);
const ctx = canvas.getContext('2d');
// VPN 实现
class H2VPN {
constructor() {
this.username = 'admin';
this.password = 'password';
this virshid = '123456';
this virshid2 = 'abcdef';
this virshid3 = 'ghijk';
this virshid4 = 'lmnop';
this virshid5 = 'qrstuv';
this virshid6 = 'vwxyz';
this virshid7 = 'abcde';
this virshid8 = 'fghij';
this virshid9 = 'klmn';
this virshid1 = 'opqrs';
this virshid11 = 'tuvw';
this virshid12 = 'xyz';
}
encrypt(string) {
let encrypted = '';
for (let i = 0; i < string.length; i++) {
encrypted += string.charCodeAt(i) ^ 0x12;
}
return encrypted;
}
decrypt(encrypted) {
let decrypted = '';
for (let i = 0; i < encrypted.length; i++) {
decrypted += encrypted.charCodeAt(i) ^ 0x12;
}
return decrypted;
}
connect() {
let url = `https://192.168.1.1:1143`;
let response = fetch(url);
if (!response.ok) {
throw new Error('连接失败');
}
let data = await response.json();
let user = data.user;
let pwd = data.pwd;
let res = await response.json();
let res_data = res.body;
let user_encrypted = this.encrypt(pwd);
let pwd_encrypted = this.encrypt(user_encrypted);
let res = this decrypt(user_encrypted).padStart(data.length, '');
let url = `https://192.168.1.1:{res}`;
if (this.check(url)) {
response.status(2).send(url);
} else {
throw new Error('连接失败');
}
}
check(url) {
let response = fetch(url);
if (!response.ok) {
throw new Error('URL 未接受');
}
let data = await response.json();
if (data.error) {
throw new Error('错误数据');
}
return true;
}
}
// 在设置界面添加 VPN 实现
const user = new H2VPN();
结合城市地图
为了更真实地模拟城市环境,我们可以将 VPN 设置界面与城市地图结合，例如使用 JX-Canvas 来绘制城市道路、建筑和树木。

// 建立 VPN 站点
let window;
let server = document.createElement('div');
server.className = 'block w-5 h-5 bg-white border-2';
window = document.createElement('div');
window.className = 'container w-full h-full';
window.style.position = 'absolute';
window.style.left = '5';
window.style.top = '5';
window.style.transform = 'translate(-5px,-5px) rotate(45deg)';
window.style.width = '4px';
window.style.height = '4px';
window.addEventListener('click', () => {
let url = `https://192.168.1.1:${password}`;
let response = await fetch(url);
if (!response.ok) {
throw new Error('连接失败');
}
let data = await response.json();
console.log(data);
});
// 设置 VPN
if (res.error) {
alert('设置失败，请检查网络和密码');
} else
