Php Nginx不将Cookies传递给代理

我有一个cookie集可以用于所有子域，.example.com。我让nginx-ajax调用通过代理传递，但cookie不会保留。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，它看起来是这样的：

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;
    }

}

上图显示发送的cookie的域应为N/a。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？

请求cookie总是不适用，所以它没有任何意义。你用AJAX请求什么路径？@devindixon我也面临同样的问题。您找到解决方案了吗？samw问题您对此做了什么？请您解释一下您的解决方案是如何工作的，以使人们能够从中学习：）

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