我正在尝试同时使用 UDP 服务器来连续监听数据报和 http 服务器,但是字符串“UDP 服务器启动并监听端口...”和命令“server.Run()”从未到达。
package main
import (
"fmt"
"github.com/gin-gonic/gin"
"log"
"net"
)
func handleUDPConnection(conn *net.UDPConn) {
buffer := make([]byte, 8096)
n, addr, err := conn.ReadFromUDP(buffer)
if err != nil {
log.Fatal(err)
} else {
fmt.Println("UDP client: ", addr)
fmt.Println("Received from UDP client: ", string(buffer[:n]))
}
}
func main() {
server := gin.Default()
host, port := "localhost", "41234"
udpAddr, err := net.ResolveUDPAddr("udp4", fmt.Sprintf("%s:%s", host, port))
if err != nil {
log.Fatal(err)
}
conn, err := net.ListenUDP("udp", udpAddr)
if err != nil {
log.Fatal(err)
}
defer conn.Close()
server.GET("/ping", func(c *gin.Context) {
c.JSON(200, gin.H{"message": "pong"})
})
for {
handleUDPConnection(conn)
}
fmt.Sprintf("UDP server up and listening on port %s\n", port)
server.Run()
}
我怎样才能让它工作?
