# Socks5SSProxy
单Socks5转换成多用户(端口)Shadowsocks代理. 适用于使用中转加速的用户或中转SS服务商.
## 已支持的加密算法
* rc4-md5
* aes-192-cfb
* aes-256-cfb
> 如自行添加加密算法请实现`ISSCryptoMethod`接口
## 查询已支持的加密算法
```typescript
import SSCrypto from "./src/Crypto/SSCrypto";
/* SSCrypto.getAllCryptoMethods():List 返回加密算法名数组 */
console.log(SSCrypto.getAllCryptoMethods());
```
## 创建一个Socks5转Shadowsocks代理
开始接受Shadowsocks客户端传入连接:
```typescript
import Socks5SSProxy from "./src/Socks5SSProxy";
import Socks5SSProxyTcpProcess from "./src/Socks5SSProxyTcpProcess";
/*
Shadowsocks服务端监听3389端口, 并将流量处理转发至192.168.0.250:22 Socks5服务端端口.
Shadowsocks服务端所接受的算法:rc4-md5 密码: 123456
*/
var proxy: Socks5SSProxy = new Socks5SSProxy(3389, "192.168.0.250", 22, "rc4-md5", "123456");
proxy.on("error", (err: Error) => {
console.error("代理服务器出现错误:", err);
});
proxy.listen();
```
> 如您想创建多个Shadowsocks服务端, 您只需要实例化多个`Socks5SSProxy`即可.
关闭全部Shadowsocks与Socks5连接并停止监听:
```typescript
proxy.close();
```
## Socks5转Shadowsocks服务事件
当您实例化`Socks5SSProxy`并调用`listen`方法后, 如有新连接传入则会触发`clientConnected`事件.
`clientConnected`事件会传给你一个`Socks5SSProxyTcpProcess`实例.
`Socks5SSProxyTcpProcess`为处理转发TCP过程类您可以监听其事件来干一些破事.
事件列表:
* `socks5Connected`: Socks5连接并握手成功.
* `firstTraffic`: Shadowsocks客户端与Socks5服务端首次通讯. 返回`耗时(ms)`.
* `socks5Data`: Socks5服务端 -> Shadowsocks客户端 __已解密__ 数据.
* `clientData`: Shadowsocks客户端 -> Socks5服务端 __已解密__ 数据.
* `close`: Shadowsocks客户端或Socks5服务端关闭了连接.
* `error`: 转发过程中出现了错误. 返回`Error`.
使用:
```typescript
proxy.on("clientConnected", (p: Socks5SSProxyTcpProcess) => {
p.on("socks5Connected", () => {
...
});
p.on("firstTraffic", (time: number) => {
var remoteAddress: string = `${p.getRemoteAddress()}:${p.getRemotePort()}`;
var clientAddress: string = `${p.getClientSocket().remoteAddress}:${p.getClientSocket().remotePort}`;
console.log(`Client [${clientAddress}] connected to [${remoteAddress}]. Usage time: ${time}ms`);
});
p.on("socks5Data", (data: Buffer) => {
/* 记录Shadowsocks客户端下行流量
如果您想判断这个连接是不是HTTP连接, 您针对首包可以使用:
data.toString().indexOf("HTTP/1.1 ") != -1
这样简易的方式来判断.
*/
upload += data.length;
});
p.on("clientData", (data: Buffer) => {
/* 记录Shadowsocks客户端上行流量 */
download += data.length;
});
p.on("close", () => {
...
});
p.on("error", (err: Error) => {
console.log(`Process Error:`, err.message);
});
});
```
## Examples
* 屏蔽特定域名或IP
```typescript
var checkedAddress = false;
p.on("clientData", (data: Buffer) => {
/* 避免多次判断造成性能下降 */
if (!checkedAddress) {
var addressBlockList: Array = [
"api.map.baidu.com",
"ps.map.baidu.com",
"sv.map.baidu.com",
"offnavi.map.baidu.com",
"newvector.map.baidu.com",
"ulog.imap.baidu.com",
"newloc.map.n.shifen.com",
];
for (var address of addressBlockList) {
if (address != p.getRemoteAddress()) {
continue;
}
var remoteAddress: string = `${p.getRemoteAddress()}:${p.getRemotePort()}`;
var clientAddress: string = `${p.getClientSocket().remoteAddress}:${p.getClientSocket().remotePort}`;
console.log(`Client [${clientAddress}] try to connect to [${remoteAddress}].`);
return p.clearConnect();
}
checkedAddress = true;
}
/* 记录Shadowsocks客户端上行流量 */
download += data.length;
});
```
