GO TCP代理(可代理SQLSERVER\MYSQL\ORCALE)
用nginx代理不知道为什么内网能用,外网用不了,改用go写个代理临时用下,直接上代码
package main import ( "fmt" "io" "log" "net" ) var addr string = "0.0.0.0:51415" //代理服务端口 var dest_addr string = "192.168.2.120:1433" //目标地址 func main() { defer func() { if err := recover(); err != nil { log.Println("捕获异常并恢复,异常是:", err) } }() listener, err := net.Listen("tcp", addr) if err != nil { log.Printf("Failed to start listener: %s", err) return } defer listener.Close() fmt.Println("Proxy server is listening on ", addr) for { client, err := listener.Accept() if err != nil { log.Printf("Failed to accept client connection: %s", err) continue } go handleClient(client, dest_addr) } } func handleClient(client net.Conn, remoteAddr string) { remote, err := net.Dial("tcp", remoteAddr) if err != nil { log.Printf("Failed to connect to remote server: %s", err) client.Close() return } go func() { _, err := io.Copy(remote, client) if err != nil { log.Printf("Error copying from client to remote: %s", err) } }() _, err = io.Copy(client, remote) if err != nil { log.Printf("Error copying from remote to client: %s", err) } remote.Close() client.Close() }
