CakePHP Get IP Address
提问by Aditya P Bhatt
How can I get the client's IP address in CakePHP? It'd be $_SERVER['REMOTE_ADDR']in plain PHP.
我如何在 CakePHP 中获取客户端的 IP 地址？它将$_SERVER['REMOTE_ADDR']在普通的 PHP 中。
I thought it's like all $_SERVERvars and can be accessed using env('VAR_NAME'), or getClientIP()in CakePHP, but it doesn't return the same results.
我认为它就像所有的$_SERVER变量一样，可以使用env('VAR_NAME'), 或getClientIP()在 CakePHP 中访问，但它不会返回相同的结果。
Any ideas?
有任何想法吗？

CakePHP 1.x:
蛋糕PHP 1.x:
RequestHandlerComponent::getClientIp();
RequestHandlerComponent::getClientIp();
So to clarify:
所以要澄清：
public $components = array(
'RequestHandler'
);
Then in the controller method:
然后在控制器方法中：
$this->RequestHandler->getClientIp();
CakePHP 2.x & CakepPHP 3.x:
CakePHP 2.x 和 CakepPHP 3.x：
RequestHandler::getClientIp()is deprecated; you can get the client IP from the CakeRequestobject:
RequestHandler::getClientIp()已弃用；您可以从CakeRequest对象中获取客户端 IP ：
$this->request->clientIp();

CakePHP 3.x usage:
CakePHP 3.x 用法：
//in controller
$ip = $this->request->clientIp();
CakePHP 2.x usage
CakePHP 2.x 使用
//in controller
$this->request->ClientIp();
CakePHP 1.x usage
CakePHP 1.x 使用
//in controller
RequestHandlerComponent::getClientIP();

If you need to get the IP address from within a model, $this->request->getClientIp()won't work, throwing:
如果您需要从模型中获取 IP 地址，$this->request->getClientIp()则行不通，抛出：
Error:Call to a member function clientIp() on a non-object
错误：在非对象上调用成员函数 clientIp()
Use Router::getRequest()->clientIp()instead.
使用Router::getRequest()->clientIp()来代替。
So basically, Router::getRequest()can serve as a Model's replacement of the Controller's $this->request
所以基本上，Router::getRequest()可以作为示范“替代S中的控制器的$this->request

在 cakephp 3.x 中
In your controller to get the client ip - $this->request->clientIp();
在您的控制器中获取客户端 ip - $this->request->clientIp();

You can use $this->request->clientIp();to get the current visitor's IP address.
您可以使用 $this->request->clientIp();来获取当前访问者的 IP 地址。
Cake\Http\ServerRequest::clientIp()
Returns the current visitor's IP address.

Cakephp 3 have clientIP function in the class ServerRequest:
Cakephp 3 在类 ServerRequest 中有 clientIP 函数：
https://github.com/cakephp/cakephp/blob/master/src/Http/ServerRequest.php#L578
https://github.com/cakephp/cakephp/blob/master/src/Http/ServerRequest.php#L578
You can access:
您可以访问：
in a controller controller:
在控制器控制器中：
$this->request->clientIp();
in a controller controller:
在控制器控制器中：
// firts add Router support
use Cake\Routing\Router;
// Use in a method
Router::getRequest()->clientIp()
I leave the function if you use a previous version of the framework or require some special behavior:
如果您使用框架的先前版本或需要一些特殊行为，我会保留该功能：
public function clientIp()
{
if ($this->trustProxy && $this->getEnv('HTTP_X_FORWARDED_FOR')) {
$addresses = explode(',', $this->getEnv('HTTP_X_FORWARDED_FOR'));
$ipaddr = end($addresses);
} elseif ($this->trustProxy && $this->getEnv('HTTP_CLIENT_IP')) {
$ipaddr = $this->getEnv('HTTP_CLIENT_IP');
} else {
$ipaddr = $this->getEnv('REMOTE_ADDR');
}
return trim($ipaddr);
}
For example, this function returns the value ":: 1" when you work in a local environment.
例如，当您在本地环境中工作时，此函数返回值“:: 1”。
It is a good idea to add it in the bootstrap.php boot file, since you can access it from anywhere:
将它添加到 bootstrap.php 引导文件中是个好主意，因为您可以从任何地方访问它：
function clientIp($defaultIP = '127.0.0.1') {
$ipaddr = null;
if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
$ipaddr = $_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
$ipaddr = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
$ipaddr = $_SERVER['REMOTE_ADDR'];
}
$ipaddr = trim($ipaddr);
if ($ipaddr == '::1') {
$ipaddr = $defaultIP;
}
return $ipaddr;
}
good luck and happy coding! =D
祝你好运，快乐编码！=D
