使用 endless 库实现不停服更新 demo

package main

import (
    "github.com/fvbock/endless"
    "github.com/gin-gonic/gin"
    "log"
)

func main() {
    router := gin.Default()
    router.GET("/", func(c *gin.Context) {
        c.JSON(200, gin.H{"message": "pong"})
    })

    log.Printf("Starting Server")

    server := endless.NewServer(":8080", router)
    server.BeforeBegin = func(add string) {
        log.Printf("Actual pid is %d", syscall.Getpid())
    }

    err := server.ListenAndServe()
    if err != nil {
        log.Printf("Server err: %v", err)
    }

    log.Printf("Server on %d stopped", syscall.Getpid())
}
