location
This Gin middleware can be used to automatically find and expose the server's
hostname and scheme by inspecting information in the incoming http.Request.
The alternative to this plugin would be explicitly providing such information to
the server as a command line argument or environment variable.
Usage
Default
package main
import (
"github.com/gin-contrib/location"
"github.com/gin-gonic/gin"
)
func main() {
router := gin.Default()
// configure to automatically detect scheme and host
// - use http when default scheme cannot be determined
// - use localhost:8080 when default host cannot be determined
router.Use(location.Default())
router.GET("/", func(c *gin.Context) {
url := location.Get(c)
// url.Scheme
// url.Host
// url.Path
})
router.Run()
}
Custom
package main
import (
"github.com/gin-contrib/location"
"github.com/gin-gonic/gin"
)
func main() {
router := gin.Default()
// configure to automatically detect scheme and host with
// fallback to https://foo.com/base
// - use https when default scheme cannot be determined
// - use foo.com when default host cannot be determined
// - include /base as the path
router.Use(location.New(location.Config{
Scheme: "https",
Host: "foo.com",
Base: "/base",
}))
router.GET("/", func(c *gin.Context) {
url := location.Get(c)
// url.Scheme
// url.Host
// url.Path
})
router.Run()
}
