一个高性能、易用的 .NET SOCKS 代理实现,支持 SOCKS4/4a/5 协议。

NuGet

✨ 特性

  • 支持 SOCKS4、SOCKS4a 和 SOCKS5 协议
  • 支持用户名/密码认证 (SOCKS5)
  • 支持用户标识 (SOCKS4/4a)
  • 智能的资源管理
    • 自动复用相同配置的代理实例
    • 自动清理长时间未使用的代理
    • 线程安全的实现

📦 安装

dotnet add package GeekTools.SocksProxy

🚀 快速开始

基本用法

// 创建代理实例
var handler = new HttpClientHandler
{
    Proxy = SocksWebProxy.GetProxy("127.0.0.1", 1080)
};
var client = new HttpClient(handler);

SOCKS5 认证

var handler = new HttpClientHandler
{
    Proxy = SocksWebProxy.GetProxy(
        "127.0.0.1", 
        1080,
        SocksWebProxy.SocksVersion.Socks5,
        username: "user",
        password: "pass"
    )
};
var client = new HttpClient(handler);

自定义配置

var options = new SocksWebProxyOptions
{
    IdleTimeout = TimeSpan.FromHours(1),      // 代理实例闲置多久后清理
    CleanupInterval = TimeSpan.FromMinutes(10) // 检查清理间隔
};

var handler = new HttpClientHandler
{
    Proxy = SocksWebProxy.GetProxy("127.0.0.1", 1080, options: options)
};
var client = new HttpClient(handler);

🔧 配置选项

SocksWebProxyOptions

参数 类型 默认值 说明
IdleTimeout TimeSpan 30分钟 代理实例在多久未使用后清理
CleanupInterval TimeSpan 5分钟 检查清理间隔

📝 注意事项

  1. SOCKS4 只支持 IPv4
  2. SOCKS4a 添加了域名解析支持
  3. SOCKS5 支持 IPv4、IPv6 和域名
  4. 相同配置的代理实例会被自动复用
  5. 长时间未使用的代理实例会被自动清理

🔍 性能考虑

  • 实例复用
    • 相同配置的代理实例自动复用
    • 避免重复创建代理实例
  • 资源管理
    • 自动清理长时间未使用的代理实例
    • 基于最后使用时间的清理机制
  • 线程安全
    • 使用 ConcurrentDictionary 确保线程安全
    • 原子操作和锁优化

🔍 为什么需要自动清理?

代理实例的资源特性

代理实例会维护一个本地的 HTTP 代理服务器(监听本地端口),即使代理实例本身被 GC 回收,这些底层资源也可能无法及时释放,主要涉及:

  • 占用的本地端口
  • 活跃的网络连接
  • 相关的线程资源

GC 的局限性

  1. GC 只能回收托管内存,无法直接处理底层网络资源
  2. 即使实现了 finalizer,也无法保证及时执行
  3. 依赖 GC 可能导致资源长时间占用

自动清理的优势

  1. 主动释放资源

    • 及时释放端口占用
    • 立即关闭网络连接
    • 清理相关线程资源
  2. 可预测的资源管理

    • 基于实际使用时间清理
    • 避免资源耗尽风险
    • 更好的资源使用效率
  3. 性能优化

    • 减少资源竞争
    • 降低系统负载
    • 优化内存使用
