想要優雅地重啟或停止你的Web服務器，使用下面的方法 我們可以使用[fvbock/endless](https://github.com/fvbock/endless)來替換默認的`ListenAndServe`，有關詳細信息，請參閱問題[＃296](https://github.com/gin-gonic/gin/issues/296) ``` router := gin.Default() router.GET("/", handler) // [...] endless.ListenAndServe(":4242", router) ``` 一個替換方案 - [manners](https://github.com/braintree/manners)：一個Go HTTP服務器，能優雅的關閉 - [graceful](https://github.com/tylerb/graceful)：Graceful是一個go的包，支持優雅地關閉http.Handler服務器 - [grace](https://github.com/facebookgo/grace)：對Go服務器進行優雅的重啟和零停機部署 如果你的Go版本是1.8，你可能不需要使用這個庫，考慮使用http.Server內置的[Shutdown()](https://golang.org/pkg/net/http/#Server.Shutdown)方法進行優雅關閉，查看[例子](https://github.com/gin-gonic/gin/tree/master/examples/graceful-shutdown) ``` // +build go1.8 package main import ( "context" "log" "net/http" "os" "os/signal" "time" "github.com/gin-gonic/gin" ) func main() { router := gin.Default() router.GET("/", func(c *gin.Context) { time.Sleep(5 * time.Second) c.String(http.StatusOK, "Welcome Gin Server") }) srv := &http.Server{ Addr: ":8080", Handler: router, } go func() { // service connections if err := srv.ListenAndServe(); err != nil && err != http.ErrServerClosed { log.Fatalf("listen: %s\n", err) } }() // Wait for interrupt signal to gracefully shutdown the server with // a timeout of 5 seconds. quit := make(chan os.Signal) signal.Notify(quit, os.Interrupt) <-quit log.Println("Shutdown Server ...") ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second) defer cancel() if err := srv.Shutdown(ctx); err != nil { log.Fatal("Server Shutdown:", err) } log.Println("Server exiting") } ```
