+# Hook 模块使用文档
+
+## 简介
+
+Hook模块提供了一个通用的扩展点机制，允许在不修改核心代码的前提下注入自定义逻辑。
+
+**核心特点**：
+- 类型安全的泛型API
+- Hook未注册时自动fallback
+- 支持任意参数和返回值
+
+## 快速开始
+
+### 基本用法
+
+```go
+// 1. 注册Hook
+hook.RegisterHook(hook.GETIP, func(args ...any) any {
+    userId := args[0].(string)
+    return &hook.IpResult{IP: "192.168.1.1"}
+})
+
+// 2. 调用Hook
+result := hook.HookExec[hook.IpResult](hook.GETIP, "user123")
+if result != nil && result.Error() == nil {
+    ip := result.GetResult()
+}
+```
+
+### 核心API
+
+```go
+// 注册Hook函数
+func RegisterHook(key string, hook HookFunc)
+
+// 执行Hook（泛型）
+func HookExec[T any](key string, args ...any) *T
+```
+
+## 可用的Hook扩展点
+
+### 1. `GETIP` - 获取用户IP
+
+**调用位置**：`api/server.go:210`
+
+**参数**：`userId string`
+
+**返回**：`*IpResult`
+```go
+type IpResult struct {
+    Err error
+    IP  string
+}
+```
+
+**用途**：返回用户专用IP（如代理IP）
+
+---
+
+### 2. `NEW_BINANCE_TRADER` - Binance客户端创建
+
+**调用位置**：`trader/binance_futures.go:68`
+
+**参数**：`userId string, client *futures.Client`
+
+**返回**：`*NewBinanceTraderResult`
+```go
+type NewBinanceTraderResult struct {
+    Err    error
+    Client *futures.Client  // 可修改client配置
+}
+```
+
+**用途**：为Binance客户端注入代理、日志等
+
+---
+
+### 3. `NEW_ASTER_TRADER` - Aster客户端创建
+
+**调用位置**：`trader/aster_trader.go:68`
+
+**参数**：`user string, client *http.Client`
+
+**返回**：`*NewAsterTraderResult`
+```go
+type NewAsterTraderResult struct {
+    Err    error
+    Client *http.Client  // 可修改HTTP client
+}
+```
+
+**用途**：为Aster客户端注入代理等
+
+## 使用示例
+
+### 示例1：代理模块注册Hook
+
+```go
+// proxy/init.go
+package proxy
+
+import "nofx/hook"
+
+func InitHooks(enabled bool) {
+    if !enabled {
+        return  // 条件不满足，不注册
+    }
+
+    // 注册IP获取Hook
+    hook.RegisterHook(hook.GETIP, func(args ...any) any {
+        userId := args[0].(string)
+        proxyIP, err := getProxyIP(userId)
+        return &hook.IpResult{Err: err, IP: proxyIP}
+    })
+
+    // 注册Binance客户端Hook
+    hook.RegisterHook(hook.NEW_BINANCE_TRADER, func(args ...any) any {
+        userId := args[0].(string)
+        client := args[1].(*futures.Client)
+
+        // 修改client配置
+        if client.HTTPClient != nil {
+            client.HTTPClient.Transport = getProxyTransport()
+        }
+
+        return &hook.NewBinanceTraderResult{Client: client}
+    })
+}
+```
+
+## 最佳实践
+
+### ✅ 推荐做法
+
+```go
+// 1. 在注册时判断条件
+func InitHooks(enabled bool) {
+    if !enabled {
+        return  // 不注册
+    }
+    hook.RegisterHook(KEY, hookFunc)
+}
+
+// 2. 总是返回正确的Result类型
+hook.RegisterHook(hook.GETIP, func(args ...any) any {
+    ip, err := getIP()
+    return &hook.IpResult{Err: err, IP: ip}  // ✅
+})
+
+// 3. 安全的类型断言
+userId, ok := args[0].(string)
+if !ok {
+    return &hook.IpResult{Err: fmt.Errorf("参数类型错误")}
+}
+```
+
+### ❌ 避免的做法
+
+```go
+// 1. 不要在Hook内部判断条件（浪费性能）
+hook.RegisterHook(KEY, func(args ...any) any {
+    if !enabled {
+        return nil  // ❌
+    }
+    // ...
+})
+
+// 2. 不要直接panic
+hook.RegisterHook(KEY, func(args ...any) any {
+    if err != nil {
+        panic(err)  // ❌ 会导致程序崩溃
+    }
+})
+
+// 3. 不要跳过类型检查
+userId := args[0].(string)  // ❌ 可能panic
+```
+
+## 添加新Hook扩展点
+
+### 步骤1：定义Result类型
+
+```go
+// hook/my_hook.go
+package hook
+
+type MyHookResult struct {
+    Err    error
+    Data   string
+}
+
+func (r *MyHookResult) Error() error {
+    if r.Err != nil {
+        log.Printf("⚠️ Hook出错: %v", r.Err)
+    }
+    return r.Err
+}
+
+func (r *MyHookResult) GetResult() string {
+    r.Error()
+    return r.Data
+}
+```
+
+### 步骤2：定义Hook常量
+
+```go
+// hook/hooks.go
+const (
+    GETIP              = "GETIP"
+    NEW_BINANCE_TRADER = "NEW_BINANCE_TRADER"
+    NEW_ASTER_TRADER   = "NEW_ASTER_TRADER"
+    MY_HOOK            = "MY_HOOK"  // 新增
+)
+```
+
+### 步骤3：在业务代码调用
+
+```go
+result := hook.HookExec[hook.MyHookResult](hook.MY_HOOK, arg1, arg2)
+if result != nil && result.Error() == nil {
+    data := result.GetResult()
+    // 使用data
+}
+```
+
+### 步骤4：注册实现
+
+```go
+hook.RegisterHook(hook.MY_HOOK, func(args ...any) any {
+    // 处理逻辑
+    return &hook.MyHookResult{Data: "result"}
+})
+```
+
+## 常见问题
+
+**Q: Hook可以注册多个吗？**
+A: 不可以，每个Key只能注册一个Hook，后注册会覆盖前面的。如需多个逻辑，请在一个Hook函数内组合。
+
+**Q: Hook执行失败会影响主流程吗？**
+A: 不会，主流程会检查返回值，失败时会fallback到默认逻辑。
+
+**Q: 如何调试Hook？**
+A: Hook执行时会自动打印日志：
+- `🔌 Execute hook: {KEY}` - Hook存在并执行
+- `🔌 Do not find hook: {KEY}` - Hook未注册
+
+**Q: 如何测试Hook？**
+```go
+func TestHook(t *testing.T) {
+    // 清空全局Hook
+    hook.Hooks = make(map[string]hook.HookFunc)
+
+    // 注册测试Hook
+    hook.RegisterHook(hook.GETIP, func(args ...any) any {
+        return &hook.IpResult{IP: "127.0.0.1"}
+    })
+
+    // 验证
+    result := hook.HookExec[hook.IpResult](hook.GETIP, "test")
+    assert.Equal(t, "127.0.0.1", result.IP)
+}
+```
+
