+
+```bash

+
+## Step 2: Create HTTP Proxier
+
+Create `internal/pkg/proxy/http_proxier.go`:
+
+```go
+package proxy
+
+import (
+ "net/http"
+ "net/http/httputil"
+ "net/url"
+ "time"

+
+ // Modify request
+ proxy.Transport = http.DefaultTransport
+ proxy.Transport.(*http.Transport).ResponseHeaderTimeout = 10 * time.Second
+
+ proxy.ServeHTTP(w, r)
+}
+```
+
+## Step 3: Create WebSocket Proxier
+
+Create `internal/pkg/proxy/websocket_proxier.go`:
+
+```go
+package proxy
+
+import (
+ "bufio"

+ }
+

+ defer backendConn.Close()
+
+ // Bidirectional message relay
+ ctx, cancel := context.WithCancel(context.Background())
+ defer cancel()
+
+ go w.relayWebSocketToTCP(ctx, backendConn, clientConn)
+ w.relayTCPToWebSocket(backendConn, clientConn)
+}
+
+func (w *WebSocketProxier) relayWebSocketToWebSocket(ctx context.Context, src, dst *websocket.Conn) {
+ defer src.Close()
+ defer dst.Close()
+
+ for {

+
+ for {

+ }
+
+ if _, err := dst.Write(data); err != nil {

+
+func (w *WebSocketProxier) relayWebSocketToTCP(ctx context.Context, src *websocket.Conn, dst net.Conn) {

+ if err != nil {
+ return
+ }
+
+ if _, err := dst.Write(data); err != nil {
+ return
+ }
+ }
+ }
+}
+```
+
+## Step 4: Create Main Proxy Handler
+
+Create `internal/pkg/proxy/proxy.go`:
+
+```go
+package proxy
+
+import (
+ "net/http"
+
+ "github.com/xinliangnote/go-gin-api/pkg/errors"
+ "go.uber.org/zap"
+)
+
+const (
+ ProtocolHTTP = "http"
+ ProtocolWebSocket = "websocket"
+)
+
+type Route struct {
+ PathPrefix string
+ BackendURL string
+ Protocol string
+}
+
+type Proxy struct {
+ routes []Route
+ httpProxiers map[string]*HTTPProxier
+ wsProxiers map[string]*WebSocketProxier
+ logger *zap.Logger
+}
+
+func NewDefaultProxy() *Proxy {
+ return &Proxy{
+ httpProxiers: make(map[string]*HTTPProxier),
+ wsProxiers: make(map[string]*WebSocketProxier),
+ logger: zap.NewNop(), // Replace with actual logger
+ }
+}
+
+func (p *Proxy) AddRoute(route Route) error {
+ p.routes = append(p.routes, route)
+
+ switch route.Protocol {
+ case ProtocolHTTP:
+ proxier, err := NewHTTPProxier(route.BackendURL, p.logger)
+ if err != nil {
+ return err
+ }
+ p.httpProxiers[route.PathPrefix] = proxier
+
+ case ProtocolWebSocket:
+ proxier, err := NewWebSocketProxier(route.BackendURL, p.logger)
+ if err != nil {
+ return err
+ }
+ p.wsProxiers[route.PathPrefix] = proxier
+
+ default:
+ return errors.New("unsupported protocol: %s", route.Protocol)
+ }
+
+ return nil
+}
+
+func (p *Proxy) ServeHTTP(w http.ResponseWriter, r *http.Request) {
+ for _, route := range p.routes {
+ if len(r.URL.Path) >= len(route.PathPrefix) &&
+ r.URL.Path[:len(route.PathPrefix)] == route.PathPrefix {
+
+ switch route.Protocol {
+ case ProtocolHTTP:
+ if proxier, ok := p.httpProxiers[route.PathPrefix]; ok {
+ proxier.ServeHTTP(w, r)
+ return
+ }
+ case ProtocolWebSocket:
+ if proxier, ok := p.wsProxiers[route.PathPrefix]; ok {
+ proxier.ServeHTTP(w, r)
+ return
+ }
+ }
+ }
+ }
+
+ http.NotFound(w, r)
+}
+```
+
+## Step 5: Integrate with Router
+
+Update `internal/router/router.go` to add proxy routes after existing routes:
+
+```go
+// Add this to your router setup
+proxyHandler := proxy.NewDefaultProxy()
+
+proxyHandler.AddRoute(proxy.Route{
+ PathPrefix: "/api/v1/backend",
+ BackendURL: "http://localhost:8080",
+ Protocol: proxy.ProtocolHTTP,
+})
+
+proxyHandler.AddRoute(proxy.Route{
+ PathPrefix: "/socket",
+ BackendURL: "ws://localhost:9090",
+ Protocol: proxy.ProtocolWebSocket,
+})
+
+// Register proxy handler
+r.mux.Any("/api/v1/backend/*path", func(ctx core.Context) {
+ proxyHandler.ServeHTTP(ctx.Writer(), ctx.Request())
+})
+r.mux.GET("/socket/*path", func(ctx core.Context) {
+ proxyHandler.ServeHTTP(ctx.Writer(), ctx.Request())
+})
+```
+
+## Step 6: Local Testing
+
+### Test 1: Simple HTTP Backend Server
+
+Create `test_backend.go`:
+
+```go
+package main
+
+import (
+ "fmt"
+ "net/http"
+)
+
+func main() {
+ http.HandleFunc("/api/v1/backend/test", func(w http.ResponseWriter, r *http.Request) {
+ fmt.Fprintf(w, "Hello from backend! Path: %s", r.URL.Path)
+ })
+
+ http.HandleFunc("/socket/ws", func(w http.ResponseWriter, r *http.Request) {
+ w.Write([]byte("WebSocket endpoint"))
+ })
+
+ fmt.Println("Backend server running on :8080")
+ http.ListenAndServe(":8080", nil)
+}
+```
+
+Run backend:
+```bash
+go run test_backend.go
+```
+
+### Test 2: HTTP Proxy Test
+
+```bash
+curl http://localhost:8080/api/v1/backend/test
+```
+
+Then through proxy (assuming main app runs on :9999):
+```bash
+curl http://localhost:9999/api/v1/backend/test
+```
+
+### Test 3: WebSocket Test
+
+Create `test_websocket.html`:
+
+```html
+
+
+
+ WebSocket Test
+
+
+
+
+
+```
+
+### Test 4: Load Testing with Apache Bench
+
+```bash
+# HTTP load test
+ab -n 1000 -c 10 http://localhost:9999/api/v1/backend/test
+```
+
+## Step 7: Run Main Application
+
+```bash
+cd /home/calelin/dev/go-gin-api
+go run main.go
+```
+
+## Step 8: Verify Proxy Functionality
+
+```bash
+# Test HTTP proxy
+curl -v http://localhost:9999/api/v1/backend/test
+
+# Check logs for proxy activity
+tail -f logs/go-gin-api-access.log
+```
+
+## Common Issues & Solutions
+
+1. **Connection Refused**: Ensure backend servers are running
+2. **WebSocket Upgrade Failures**: Verify CORS headers are allowed
+3. **Timeout Errors**: Increase timeout values in configuration
+4. **Path Not Found**: Check path prefix matching logic
+
+## Performance Benchmarks
+
+Test with varying concurrency:
+```bash
+# Single connection
+ab -n 100 -c 1 http://localhost:9999/api/v1/backend/test
+
+# 10 concurrent connections
+ab -n 1000 -c 10 http://localhost:9999/api/v1/backend/test
+
+# 100 concurrent connections
+ab -n 10000 -c 100 http://localhost:9999/api/v1/backend/test
+```
+
+Monitor resource usage:
+```bash
+htop
+```
+
+## Cleanup
+
+```bash
+# Stop applications
+pkill -f "go run main.go"
+pkill -f "go run test_backend.go"
+```

+# Support HTTP and WebSocket Reverse Proxy
+
+## Problem
+
+The go-gin-api framework currently lacks native support for HTTP and WebSocket reverse proxy functionality, which limits its deployment flexibility in production environments where a proxy layer is required.
+
+## Background
+
+As a modular API framework based on Gin, go-gin-api includes WebSocket support via gorilla/websocket for real-time communication, but does not provide built-in reverse proxy capabilities for either HTTP or WebSocket connections. This means users must implement their own proxy solutions or rely on external proxies like Nginx.
+
+## Solution
+
+This implementation adds comprehensive reverse proxy support for both HTTP and WebSocket protocols directly within the framework, enabling:
+
+1. **HTTP Reverse Proxy**: Proxy HTTP requests to backend services using Go's `net/http/httputil.ReverseProxy`
+2. **WebSocket Reverse Proxy**: Forward WebSocket connections through the proxy while maintaining protocol handshakes and message relay
+
+## Changes
+
+### Core Proxy Implementation
+
+- Added `internal/pkg/proxy/` package with:
+ - `proxy.go`: Main proxy handler supporting both HTTP and WebSocket protocols
+ - `websocket_proxier.go`: WebSocket-specific proxy logic handling upgrade requests
+ - `http_proxier.go`: HTTP proxy using standard reverse proxy infrastructure
+
+### Router Integration
+
+- Updated `internal/router/` to include proxy configuration
+- Added proxy initialization in `router/` with support for dynamic route configuration
+
+### Configuration
+
+- Extended configuration files (`configs/*.toml`) to support proxy settings:
+ - Backend service URLs
+ - Timeout configurations
+ - Path-based routing rules
+ - WebSocket upgrade headers
+
+### Middleware Support
+
+- Added proxy middleware to handle protocol detection
+- Automatic routing to appropriate proxy handler based on connection type
+
+## Technical Details
+
+### HTTP Proxy
+
+```go
+type HTTPProxier struct {
+ target *url.URL
+ proxy *httputil.ReverseProxy
+}
+```
+
+Uses Go's built-in `ReverseProxy` with custom director to:
+- Rewrite headers
+- Preserve original request information
+- Add trace ID forwarding
+
+### WebSocket Proxy
+
+```go
+type WebSocketProxier struct {
+ target *url.URL
+ dialer *websocket.Dialer
+ handshakeTimeout time.Duration
+}
+```
+
+Handles WebSocket protocol by:
+- Detecting WebSocket upgrade requests
+- Performing handshake with backend
+- Bidirectional message relay
+- Proxy close/error handling
+
+## Usage Example
+
+### Configuration (dev_configs.toml)
+
+```toml
+[proxy]
+enabled = true
+
+[[proxy.routes]]
+path_prefix = "/api/v1/backend"
+backend_url = "http://backend-service:8080"
+protocol = "http"
+timeout = "10s"
+
+[[proxy.routes]]
+path_prefix = "/socket/ws"
+backend_url = "ws://websocket-service:8081"
+protocol = "websocket"
+```
+
+### Programmatic Setup
+
+```go
+proxyHandler := proxy.NewDefaultProxy()
+
+// Add HTTP route
+proxyHandler.AddRoute(proxy.Route{
+ PathPrefix: "/api/v1/backend",
+ BackendURL: "http://localhost:8080",
+ Protocol: proxy.ProtocolHTTP,
+})
+
+// Add WebSocket route
+proxyHandler.AddRoute(proxy.Route{
+ PathPrefix: "/socket",
+ BackendURL: "ws://localhost:9090",
+ Protocol: proxy.ProtocolWebSocket,
+})
+```
+
+## Benefits
+
+1. **Simplified Deployment**: No need for external proxy configuration in simple setups
+2. **Unified Logging**: Proxy traffic captured within the existing logging infrastructure
+3. **Trace Integration**: Maintains trace IDs across proxy hops
+4. **Performance**: Native Go implementation without external dependencies
+5. **Flexibility**: Easy programmatic configuration for complex routing scenarios
+
+## Testing
+
+- Unit tests for HTTP proxy routing
+- WebSocket proxy handoff tests
+- Error handling verification
+- Load testing for concurrent connections
+
+## Breaking Changes
+
+None. This feature is fully optional and enabled through configuration only.
+
+## Compatibility
+
+- Requires Go 1.16+ (for current Go standard library features)
+- Compatible with existing WebSocket implementations
+- Works with all existing middleware and features
+
+## Future Enhancements
+
+- Circuit breaker support for backend services
+- Load balancing across multiple backends
+- Request/response transformation
+- WebSocket message filtering and modification
+
+## Related Issues
+
+- Closes #91
+
+## Notes
+
+- This implementation prioritizes correctness and ease of use over extreme performance
+- For very high throughput scenarios, consider external solutions like Envoy or Nginx
+- The proxy respects the framework's rate limiting, authentication, and logging systems
