php - Nginx 不会将 Cookie 传递给代理

Question

我有一个 cookie 集，适用于所有子域，.example.com。我有 nginx ajax 调用通过 proxy_pass 但 cookie 不保留。我的配置如下所示:

server {
    listen   80;
    server_name  www.example.com;

    location / {
        root   /data/sites/www.example.com/widgets/public_html;
        index  index.php index.html index.htm;
        try_files $uri $uri/ /index.php?rt=$uri&$args;
    }

    location ~ .php$ {
      root          /data/sites/www.example.com/site/public_html;
      fastcgi_pass   127.0.0.1:9000;
      fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
      fastcgi_param REQUEST_URI    $uri;
      fastcgi_index  index.php;
      include        fastcgi_params;
      fastcgi_param ENV staging;
    }


    location /api {
        proxy_pass_header  Set-Cookie;
        proxy_cookie_domain $host example.com;
        proxy_pass_header  P3P;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Fowarded-Host $host;
        proxy_pass http://api.example.com/;
        proxy_connect_timeout 1;
    }

}

但是当我检查 ajax 调用时，它看起来像这样:

上图显示发送的 cookie 的域为 N/A，而本应为 .example.com。它适用于我的 Apache/PHP 配置，但不适用于我的 nginx/php 配置。我做错了什么？

Answer 1

location / {
  proxy_pass http://localhost:8000;
  proxy_set_header Host $host; # MAGIC
}
