如何在Laravel 5+中获取客户端IP地址

我正在尝试在Laravel中获取客户端的IP地址。

使用可以很容易地在PHP中获得客户端的IP

$_SERVER["REMOTE_ADDR"]。在核心PHP中它可以正常工作,但是当我在Laravel中使用相同的东西时,它将返回服务器IP而不是访问者的IP。

回答:

查看Laravel API:

Request::ip();

在内部,它使用Symfony Request对象中的getClientIps方法:

public function getClientIps()

{

$clientIps = array();

$ip = $this->server->get('REMOTE_ADDR');

if (!$this->isFromTrustedProxy()) {

return array($ip);

}

if (self::$trustedHeaders[self::HEADER_FORWARDED] && $this->headers->has(self::$trustedHeaders[self::HEADER_FORWARDED])) {

$forwardedHeader = $this->headers->get(self::$trustedHeaders[self::HEADER_FORWARDED]);

preg_match_all('{(for)=("?\[?)([a-z0-9\.:_\-/]*)}', $forwardedHeader, $matches);

$clientIps = $matches[3];

} elseif (self::$trustedHeaders[self::HEADER_CLIENT_IP] && $this->headers->has(self::$trustedHeaders[self::HEADER_CLIENT_IP])) {

$clientIps = array_map('trim', explode(',', $this->headers->get(self::$trustedHeaders[self::HEADER_CLIENT_IP])));

}

$clientIps[] = $ip; // Complete the IP chain with the IP the request actually came from

$ip = $clientIps[0]; // Fallback to this when the client IP falls into the range of trusted proxies

foreach ($clientIps as $key => $clientIp) {

// Remove port (unfortunately, it does happen)

if (preg_match('{((?:\d+\.){3}\d+)\:\d+}', $clientIp, $match)) {

$clientIps[$key] = $clientIp = $match[1];

}

if (IpUtils::checkIp($clientIp, self::$trustedProxies)) {

unset($clientIps[$key]);

}

}

// Now the IP chain contains only untrusted proxies and the client IP

return $clientIps ? array_reverse($clientIps) : array($ip);

}
