关于 Request::getClientIps () 获取真实 IP 的一些疑问

使用 setTrustedHeaderName() 做设置。

getClientIp 有个注释可以看看

/**
 * Returns the client IP address.
 *
 * This method can read the client IP address from the "X-Forwarded-For" header
 * when trusted proxies were set via "setTrustedProxies()". The "X-Forwarded-For"
 * header value is a comma+space separated list of IP addresses, the left-most
 * being the original client, and each successive proxy that passed the request
 * adding the IP address where it received the request from.
 *
 * If your reverse proxy uses a different header name than "X-Forwarded-For",
 * ("Client-Ip" for instance), configure it via "setTrustedHeaderName()" with
 * the "client-ip" key.
 *
 * @return string The client IP address
 *
 * @see getClientIps()
 * @see http://en.wikipedia.org/wiki/X-Forwarded-For
 */
public function getClientIp()

@Summer 解决了 :D
需要提前设置好可信任IP，因为当前机器上一层还有一个nginx，也属于内网的，需要把上一层的IP设置到信任列表里，才会继续获取到最外层的真实IP

具体方法:

Request::setTrustedProxies(['192.168.0.1'])

Request::getClientIp() // 获取真实IP

@FreeDKR 你一个参数是如何实现的，查询setTrustedProxies方法后是两个参数

@FreeDKR 这个和前后端分离也有关系，我的前端是跑在本地的，获取不到支持前端的服务器，但是我放到了服务器上使用 Request::setTrustedProxies(['192.168.0.1']) Request::getClientIp() // 获取真实 IP
使用这个是可以获取到IP的

Laravel 5.8.*

request()->setTrustedProxies(request()->getClientIps(), \Illuminate\Http\Request::HEADER_X_FORWARDED_FOR);
