在Amazon EC2 / Nginx中获取客户端IP

Question

I'm trying to get Client IP using Laravel 5.2

It is not sensitive information, so I don't really care about IP Spoofing.

I tried this kind of scripts in my Model:

if (isset($_SERVER['HTTP_X_FORWARDED_FOR']) && $_SERVER['HTTP_X_FORWARDED_FOR']) {
    $clientIpAddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
    $clientIpAddress = $_SERVER['REMOTE_ADDR'];
}

But When I run php artisan migrate, I get error

Undefined index: HTTP_X_FORWARDED_FOR  

or

Undefined index: REMOTE_ADDR

But when I run:

<?php dd($_SERVER); ?>

I get

"SERVER_ADDR" => "10.0.1.194"
"REMOTE_PORT" => "38151"
"REMOTE_ADDR" => "201.141.124.254"

I don't understand !!!

Answer 1

This is just because you running this in CLI (you use console to run migration).

PHP in CLI mode has another $_SERVER and has not REMOTE_ADDR key.
