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);
}
