## Dynamic API
使用 Dynamic API 功能，你可以在运行时动态管理入站、出站和路由规则。
### 编译时启用 Dynamic API
在编译时添加 `with_dynamic_api` 标签：
```bash
go build -tags "with_dynamic_api" ./cmd/sing-box
```
或者修改 `Makefile` 中的 `TAGS` 变量：
```
TAGS ?= with_gvisor,with_dhcp,with_wireguard,with_reality_server,with_clash_api,with_quic,with_utls,with_tailscale,with_dynamic_api
```
### 配置文件示例
在配置文件的 `experimental` 部分添加：
```json
{
"log": {
"level": "info",
"timestamp": true
},
"inbounds": [
{
"type": "http",
"tag": "http-in",
"listen_port": 20808,
"listen": "127.0.0.1"
},
{
"type": "tun",
"tag": "tun-in",
"interface_name": "sing-box",
"inet4_address": "172.19.0.1/30",
"auto_route": true,
"stack": "system",
"sniff": true
}
],
"outbounds": [
{
"type": "direct",
"tag": "direct"
},
{
"type": "block",
"tag": "block"
}
],
"route": {
"auto_detect_interface": true,
"rules": [
{
"action": "sniff"
},
{
"protocol": "dns",
"action": "hijack-dns"
}
],
"find_process": true,
"final": "direct"
},
"experimental": {
"dynamic_api": {
"listen": "127.0.0.1:9090",
"secret": "your_secret_key"
}
}
}
```
### API 用法
Dynamic API 提供以下功能：
- 动态添加/删除入站
- 动态添加/删除出站
- 动态添加/删除路由规则
详细 API 文档请参考官方文档。
### 使用示例
#### 动态添加入站
```bash
curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer your_api_secret" \
http://127.0.0.1:9090/api/inbound \
-d '{
"tag": "http_in",
"type": "http",
"listen": "127.0.0.1",
"listen_port": 10080,
"users": [
{
"username": "user",
"password": "pass"
}
]
}'
```
#### 删除入站
```bash
curl -X DELETE -H "Authorization: Bearer your_api_secret" \
http://127.0.0.1:9090/api/inbound/http_in
```
#### 列出所有入站
```bash
curl -H "Authorization: Bearer your_api_secret" \
http://127.0.0.1:9090/api/inbound
```
#### 动态添加出站
```bash
curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer your_api_secret" \
http://127.0.0.1:9090/api/outbound \
-d '{
"tag": "proxy_out",
"type": "vmess",
"server": "example.com",
"server_port": 443,
"security": "auto",
"uuid": "bf000d23-0752-40b4-affe-68f7707a9661",
"alter_id": 0,
"tls": {
"enabled": true,
"server_name": "example.com"
}
}'
#
{
"type": "vless",
"tag": "proxy1",
"server": "shen.86782889.xyz",
"server_port": 55536,
"uuid": "1ecd415e-6b5a-5988-c66f-2e67f28d1e72",
"flow": "",
"network": "tcp",
"tls": {
"enabled": true,
"server_name": "shen.86782889.xyz",
"insecure": false
},
"transport": {
"type": "ws",
"path": "/SHDsdfsjk2365"
}
}
#
```
#### 删除出站
```bash
curl -X DELETE -H "Authorization: Bearer your_api_secret" \
http://127.0.0.1:9090/api/outbound/proxy_out
```
#### 动态添加路由规则
```bash
curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer your_api_secret" \
http://127.0.0.1:9090/api/route/rule \
-d '{
"domain": ["example.com"],
"outbound": "proxy_out"
}'
```
也可以根据进程名添加规则：
```bash
curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer your_api_secret" \
http://127.0.0.1:9090/api/route/rule \
-d '{
"process_name": ["ip2.exe"],
"outbound": "socks-out1"
}'
```
或根据进程PID添加规则：
```bash
curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer your_api_secret" \
http://127.0.0.1:9090/api/route/rule \
-d '{
"process_pid": [13588],
"outbound": "proxy1"
}'
```
#### 删除路由规则
路由规则通过索引删除，首先可以列出所有规则：
```bash
curl -H "Authorization: Bearer your_api_secret" \
http://127.0.0.1:9090/api/route/rules
```
然后删除指定索引的规则（例如删除索引为0的规则）：
```bash
curl -X DELETE -H "Authorization: Bearer your_api_secret" \
http://127.0.0.1:9090/api/route/rule/0
```

# Dynamic API 使用指南
## 配置说明
在 `config.json` 中启用 Dynamic API：
```json
{
"log": {
"level": "info",
"timestamp": true
},
"inbounds": [
{
"type": "tun",
"tag": "tun-in",
"interface_name": "sing-box",
"inet4_address": "172.19.0.1/30",
"auto_route": true,
"stack": "system",
"sniff": true
}
],
"outbounds": [
{
"type": "direct",
"tag": "direct"
},
{
"type": "block",
"tag": "block"
}
],
"route": {
"auto_detect_interface": true,
"rules": [
{
"action": "sniff"
},
{
"protocol": "dns",
"action": "hijack-dns"
}
],
"find_process": true,
"final": "direct"
},
"experimental": {
"dynamic_api": {
"listen": "127.0.0.1:9091",
"secret": "your_secret_key111111",
"enable_config_save": true,
"config_save_path": "dynamic_config.json"
}
}
}
```
参数说明：
- `listen`: API 服务监听地址
- `secret`: API 访问密钥，用于认证
- `enable_config_save`: 是否启用配置保存功能
- `config_save_path`: 动态配置保存路径
## API 端点
### 入站管理
#### 创建入站
```bash
curl -X POST http://127.0.0.1:9091/api/inbound \
-H "Authorization: your_secret_key" \
-H "Content-Type: application/json" \
-d '{
"type": "http",
"tag": "http-in",
"listen": "127.0.0.1",
"listen_port": 1080
}'
```
#### 删除入站
```bash
curl -X DELETE http://127.0.0.1:9091/api/inbound/http-in \
-H "Authorization: your_secret_key"
```
#### 列出所有入站
```bash
curl http://127.0.0.1:9091/api/inbound \
-H "Authorization: your_secret_key"
```
### 出站管理
#### 创建出站
```bash
# VLESS 出站示例
curl -X POST http://127.0.0.1:9091/api/outbound \
-H "Authorization: your_secret_key" \
-H "Content-Type: application/json" \
-d '{
"type": "vless",
"tag": "proxy1",
"server": "example.com",
"server_port": 443,
"uuid": "1234567890-abcd-efgh-ijkl",
"flow": "",
"network": "tcp",
"tls": {
"enabled": true,
"server_name": "example.com",
"insecure": false
},
"transport": {
"type": "ws",
"path": "/path"
}
}'
# Shadowsocks 出站示例
curl -X POST http://127.0.0.1:9091/api/outbound \
-H "Authorization: your_secret_key" \
-H "Content-Type: application/json" \
-d '{
"type": "shadowsocks",
"tag": "ss-out",
"server": "example.com",
"server_port": 8388,
"method": "aes-256-gcm",
"password": "your_password"
}'
```
#### 删除出站
```bash
curl -X DELETE http://127.0.0.1:9091/api/outbound/proxy1 \
-H "Authorization: your_secret_key"
```
#### 列出所有出站
```bash
curl http://127.0.0.1:9091/api/outbound \
-H "Authorization: your_secret_key"
```
#### 测试出站连接
```bash
curl -X POST http://127.0.0.1:9091/api/outbound/test \
-H "Authorization: your_secret_key" \
-H "Content-Type: application/json" \
-d '{
"tag": "proxy1",
"test_url": "http://www.gstatic.com/generate_204"
}'
```
### 路由规则管理
#### 创建路由规则
```bash
# 进程规则示例
curl -X POST http://127.0.0.1:9091/api/route/rule \
-H "Authorization: your_secret_key" \
-H "Content-Type: application/json" \
-d '{
"process_name": ["chrome.exe"],
"outbound": "proxy1"
}'
# 域名规则示例
curl -X POST http://127.0.0.1:9091/api/route/rule \
-H "Authorization: your_secret_key" \
-H "Content-Type: application/json" \
-d '{
"domain": ["example.com", "*.example.com"],
"outbound": "proxy1"
}'
# IP 规则示例
curl -X POST http://127.0.0.1:9091/api/route/rule \
-H "Authorization: your_secret_key" \
-H "Content-Type: application/json" \
-d '{
"ip_cidr": ["192.168.1.0/24", "10.0.0.0/8"],
"outbound": "proxy1"
}'
```
#### 删除路由规则
```bash
curl -X DELETE http://127.0.0.1:9091/api/route/rule/0 \
-H "Authorization: your_secret_key"
```
#### 列出所有规则
```bash
curl http://127.0.0.1:9091/api/route/rules \
-H "Authorization: your_secret_key"
```
### 配置管理
#### 保存配置
```bash
curl -X POST http://127.0.0.1:9091/api/config/save \
-H "Authorization: your_secret_key"
```
#### 重载配置
```bash
curl -X POST http://127.0.0.1:9091/api/config/reload \
-H "Authorization: your_secret_key"
```
## 响应格式
### 成功响应
```json
{
"success": true,
"message": "操作成功",
"data": {} // 可选，包含返回数据
}
```
### 错误响应
```json
{
"error": "错误信息"
}
```
## 注意事项
1. 所有请求都需要在 Header 中包含 `Authorization` 字段，值为配置中的 `secret`
2. 删除操作会同步更新到配置文件（如果启用了配置保存功能）
3. 初始配置（来自 config.json）中的入站和出站不会被保存到动态配置文件中
4. 系统入站（如 tun）不会被包含在动态配置中
5. 配置保存功能需要在配置中明确启用（`enable_config_save: true`）
