remoteaddr

RemoteAddr Middleware

RemoteAddr provides middleware for sanitizing the RemoteAddr based on other possible headers.

Install

go get github.com/syntaqx/echo-middleware/remoteaddr

Getting Started

Here's a simple example application using remoteaddr and Echo. Save this file as main.go

package main

import (
    "net/http"

    "github.com/labstack/echo"
    "github.com/syntaqx/echo-middleware/remoteaddr"
)

func main() {
    e := echo.New()

    e.Use(remoteaddr.New().Handler)

    e.Get("/", func(c *echo.Context) error {
        return c.HTML(http.StatusOK, c.Request().RemoteAddr)
    })

    e.Run(":8080")
}

Then, run your server:

go run main.go

The server now runs on localhost:8080

$ curl -D - -H 'Origin: http://localhost' http://localhost:8080/

You should recieve a response giving you back your IP address (which, in this case will either be 127.0.0.1 or ::1). Now you can use that value safely, knowing it's being looked after!
