如何在 Laravel 5+ 中获取客户端 IP 地址

Question

I am trying to get the client's IP address in Laravel.

It is easy to get a client's IP in PHP by using $_SERVER["REMOTE_ADDR"] . It is working fine in core PHP, but when I use the same thing in Laravel, it returns the server IP instead of the visitor's IP.

Answer 1

Looking at the Laravel API<\/a> :

Request::ip();

Answer 2

If you are under a load balancer, Laravel's \\Request::ip() always returns the balancer's IP:

            echo $request->ip();
            // server ip

            echo \Request::ip();
            // server ip

            echo \request()->ip();
            // server ip

            echo $this->getIp(); //see the method below
            // clent ip

This custom method returns the real client ip:

public function getIp(){
    foreach (array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR') as $key){
        if (array_key_exists($key, $_SERVER) === true){
            foreach (explode(',', $_SERVER[$key]) as $ip){
                $ip = trim($ip); // just to be safe
                if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false){
                    return $ip;
                }
            }
        }
    }
    return request()->ip(); // it will return server ip when no client ip found
}

In addition to this I suggest you to be very careful using Laravel's throttle middleware: It uses Laravel's Request::ip() as well, so all your visitors will be identified as the same user and you will hit the throttle limit very quickly. I experienced this live and this caused big issues.

To fix this:

Illuminate\\Http\\Request.php

    public function ip()
    {
        //return $this->getClientIp(); //original method
        return $this->getIp(); // the above method
    }

You can now also use Request::ip() , which should return the real IP in production.

Answer 3

Use request()->ip()<\/code> .

response()->json($v);
view('path.to.blade');
redirect();
route();
cookie();

Answer 4

Add namespace

use Request;

Answer 5

For Laravel 5 you can use the Request object. Just call its ip() method, something like:

$request->ip();

Answer 6

There are two things to take care of:

1. Get a helper function that returns a Illuminate\\Http\\Request and call the ->ip() method:

    request()->ip();

2. Think of your server configuration, it may use a proxy or load-balancer , especially in an AWS ELB configuration.

If this is your case you need to follow " Configuring Trusted Proxies " or maybe even set a "Trusting All Proxies" option.

Why? Because being your server will be getting your proxy/ load-balancer IP instead.

If you are on the AWS balance-loader, go to App\\Http\\Middleware\\TrustProxies and make $proxies declaration look like this:

protected $proxies = '*';

Now test it and celebrate because you just saved yourself from having trouble with throttle middleware. It also relies on request()->ip() and without setting "TrustProxies" up, you could have all your users blocked from logging in instead of blocking only the culprit's IP.

And because throttle middleware is not explained properly in the documentation, I recommend watching " laravel 5.2 tutorial for beginner, API Rate Limiting "

Tested in Laravel 5.7

Answer 7

In Laravel 5

public function index(Request $request) {
  $request->ip();
}

Answer 8

I tested in Laravel 8.x and you can use:

$request->ip()

Answer 9

If you call this function then you easily get the client's IP address. I have already used this in my existing project:

public function getUserIpAddr(){
       $ipaddress = '';
       if (isset($_SERVER['HTTP_CLIENT_IP']))
           $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
       else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
           $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
       else if(isset($_SERVER['HTTP_X_FORWARDED']))
           $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
       else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
           $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
       else if(isset($_SERVER['HTTP_FORWARDED']))
           $ipaddress = $_SERVER['HTTP_FORWARDED'];
       else if(isset($_SERVER['REMOTE_ADDR']))
           $ipaddress = $_SERVER['REMOTE_ADDR'];
       else
           $ipaddress = 'UNKNOWN';    
       return $ipaddress;
    }

Answer 10

In Laravel 5.4 we can't call ip static. This a correct way to get the IP of the user:

 use Illuminate\Http\Request;

public function contactUS(Request $request)
    {
        echo $request->ip();
        return view('page.contactUS');
    }

Answer 11

If you are still getting 127.0.0.1 as the IP, you need to add your "proxy", but be aware that you have to change it before going into production!

Read " Configuring Trusted Proxies ".

And add this:

class TrustProxies extends Middleware
{
    /**
     * The trusted proxies for this application.
     *
     * @var array
     */
    protected $proxies = '*';

Now request()->ip() gives you the correct IP.

Answer 12

If you want client IP and your server is behind aws elb, then user the following code. Tested for laravel 5.3

$elbSubnet = '172.31.0.0/16';
Request::setTrustedProxies([$elbSubnet]);
$clientIp = $request->ip();

Answer 13

You can get a few way ip address utilizing Request ip, Request getClientIp and solicitation partner work. In this model, I will tell you the best way to get current client ip address in laravel 5.8.

$clientIP = request()->ip();

dd($clientIP);

You can follow this from here

Answer 14

Solution 1: You can use this type of function for getting client IP

public function getClientIPaddress(Request $request) {
    $clientIp = $request->ip();
    return $clientIp;
}

Solution 2: if the solution1 is not providing accurate IP then you can use this function for getting visitor real IP.

 public function getClientIPaddress(Request $request) {

    if (isset($_SERVER["HTTP_CF_CONNECTING_IP"])) {
        $_SERVER['REMOTE_ADDR'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
        $_SERVER['HTTP_CLIENT_IP'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
    }
    $client  = @$_SERVER['HTTP_CLIENT_IP'];
    $forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
    $remote  = $_SERVER['REMOTE_ADDR'];

    if(filter_var($client, FILTER_VALIDATE_IP)){
        $clientIp = $client;
    }
    elseif(filter_var($forward, FILTER_VALIDATE_IP)){
        $clientIp = $forward;
    }
    else{
        $clientIp = $remote;
    }

    return $clientIp;
 }

NB: When you have used load-balancer / proxy-server in your live server then you need to used solution 2 for getting real visitor ip.

Answer 15

If you have multiple layer proxies just like CDN + Load Balancer.
Using Laravel Request::ip() function will get right-most proxy IP but not client IP.
You may try following solution.

protected $proxies = ['0.0.0.0/0'];

Answer 16

I used the Sebastien Horin function getIp and request()->ip() (at global request), because to localhost the getIp function return null:

public function getIp(){
foreach (array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR') as $key){
    if (array_key_exists($key, $_SERVER) === true){
        foreach (explode(',', $_SERVER[$key]) as $ip){
            $ip = trim($ip); // just to be safe
            if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false){
                return $ip;
            }
        }
    }
}

Answer 17

If you worry about getting the IP address but do not need or want to use any Laravel functionality, you can use just php:

Answer 18

This solution I used in my project. I found other solutions here either incomplete or too complex to understand.

if (! function_exists('get_visitor_IP'))
{
    /**
     * Get the real IP address from visitors proxy. e.g. Cloudflare
     *
     * @return string IP
     */
    function get_visitor_IP()
    {
        // Get real visitor IP behind CloudFlare network
        if (isset($_SERVER["HTTP_CF_CONNECTING_IP"])) {
            $_SERVER['REMOTE_ADDR'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
            $_SERVER['HTTP_CLIENT_IP'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
        }

        // Sometimes the `HTTP_CLIENT_IP` can be used by proxy servers
        $ip = @$_SERVER['HTTP_CLIENT_IP'];
        if (filter_var($ip, FILTER_VALIDATE_IP)) {
           return $ip;
        }

        // Sometimes the `HTTP_X_FORWARDED_FOR` can contain more than IPs 
        $forward_ips = @$_SERVER['HTTP_X_FORWARDED_FOR'];
        if ($forward_ips) {
            $all_ips = explode(',', $forward_ips);

            foreach ($all_ips as $ip) {
                if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE)){
                    return $ip;
                }
            }
        }

        return $_SERVER['REMOTE_ADDR'];
    }
}

Answer 19

为我工作

$requestIp  = \Request::ip();

Answer 20

When we want the user's ip_address :

$_SERVER['REMOTE_ADDR']

and want to server address:

$_SERVER['SERVER_ADDR']

Answer 21

  $ip = $_SERVER['REMOTE_ADDR'];
