记录一下workerman的ip处理,由于常驻内存的原因，workerman并不能直接获取ip和使用header等php函数。本文主要记录一下获取ip的方式。

官方示例代码：

$_SERVER['HTTP_X_REAL_IP']方式

server {
  listen 443;

  ssl on;
  ssl_certificate /etc/ssl/server.pem;
  ssl_certificate_key /etc/ssl/server.key;
  ssl_session_timeout 5m;
  ssl_session_cache shared:SSL:50m;
  ssl_protocols SSLv3 SSLv2 TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;

  location /wss
  {
    proxy_pass http://127.0.0.1:8282;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    # 这部分是利用http头透传真实客户端ip
    proxy_set_header X-Real-IP $remote_addr;
  }

  # location / {} 站点的其它配置...
}


<?php
require_once __DIR__ . '/../Workerman/Autoloader.php';
use Workerman\Worker;
$worker = new Worker('websocket://0.0.0.0:7272');

// 客户端练上来时，即完成TCP三次握手后的回调
$worker->onConnect = function($connection) {
   /**
    * 客户端websocket握手时的回调onWebSocketConnect
    * 在onWebSocketConnect回调中获得nginx通过http头中的X_REAL_IP值
    */
   $connection->onWebSocketConnect = function($connection){
       /**
        * connection对象本没有realIP属性，这里给connection对象动态添加个realIP属性
        * 记住php对象是可以动态添加属性的，你也可以用自己喜欢的属性名
        */
       $connection->realIP = $_SERVER['HTTP_X_REAL_IP'];
   };
};
$worker->onMessage = function($connection, $data)
{
    // 当使用客户端真实ip时，直接使用$connection->realIP即可
    $connection->send($connection->realIP);
};
Worker::runAll();

nginx配置

server {
    listen 80;
    server_name example.com;
    location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_read_timeout 365d;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

或简单点

server {
        server_name test.cn;
        location / {
            proxy_pass http://127.0.0.1:8080;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_set_header X-Real-IP $remote_addr;
        }
}

header获取

进入的$connection
$connection->header()->['x-real-ip'];

getRemoteIP

$worker->onConnect = function($connection)
{
    echo "new connection from ip " . $connection->getRemoteIp() . "\n";
};

总结

测试过\(_SERVER和getRemoteIP拿到的ip并不正常，使用\)connection->header()的方式能顺利拿到x-real-ip。查看资料后是workerman4.1和3.x的区别，4.1加强了http方面。
