Gin: [question] help for multiple port or multiple instance for http services

[tsingson]

hi,

func main() {
    router := gin.Default()
    router.GET("/", func(c *gin.Context) {
       ....
    })
    router.Run(":8080") // data services 

    routerAdmin := gin.Default()
    routerAdmin.GET("/", func(c *gin.Context) {
        .....
    })
    routerAdmin.Run(":8090") // admin and monitor services 
}

but , only one port ( 8080 port ) working

yet, i know there some others solution to split different URL rout for two propose.
i just want to know single program can service tow port or not.

some one help for this??
thanks a lot.

gin.Run() is blocking so you have to call them in separate goroutines if you want to accomplish that.

@tsingson @slimmy is right.

func main() {
    router := gin.Default()
    router.GET("/", func(c *gin.Context) {
       ....
    })
    go router.Run(":8080") // data services 

    routerAdmin := gin.Default()
    routerAdmin.GET("/", func(c *gin.Context) {
        .....
    })
    routerAdmin.Run(":8090") // admin and monitor services 
}

@slimmy @manucorporat thanks a lot!!

_you can do it like this:_
go func() { router1.Run("127.0.0.1:9000") }()
router2.Run("127.0.0.1:8000")

Is there support for multiple sites/vhosts?

See the PR #1119 and the following example:

package main

import (
    "log"
    "net/http"
    "time"

    "github.com/gin-gonic/gin"
    "golang.org/x/sync/errgroup"
)

var (
    g errgroup.Group
)

func router01() http.Handler {
    e := gin.New()
    e.Use(gin.Recovery())
    e.GET("/", func(c *gin.Context) {
        c.JSON(
            http.StatusOK,
            gin.H{
                "code":  http.StatusOK,
                "error": "Welcome server 01",
            },
        )
    })

    return e
}

func router02() http.Handler {
    e := gin.New()
    e.Use(gin.Recovery())
    e.GET("/", func(c *gin.Context) {
        c.JSON(
            http.StatusOK,
            gin.H{
                "code":  http.StatusOK,
                "error": "Welcome server 02",
            },
        )
    })

    return e
}

func main() {
    server01 := &http.Server{
        Addr:         ":8080",
        Handler:      router01(),
        ReadTimeout:  5 * time.Second,
        WriteTimeout: 10 * time.Second,
    }

    server02 := &http.Server{
        Addr:         ":8081",
        Handler:      router02(),
        ReadTimeout:  5 * time.Second,
        WriteTimeout: 10 * time.Second,
    }

    g.Go(func() error {
        return server01.ListenAndServe()
    })

    g.Go(func() error {
        return server02.ListenAndServe()
    })

    if err := g.Wait(); err != nil {
        log.Fatal(err)
    }
}
