流星使用Ngix进行预渲染

Question

我在我的Meteor APP上使用prerender-node，当我在本地测试抓取时，我有localhost:3000/http://stephane-richin.fr的302状态代码：

2016-09-20T07:43:13.953Z got 302 in 329ms for http://stephane-richin.fr/

如果我使用'www'进行测试：localhost:3000/http://www.stephane-richin.fr，状态代码为200（正确无误）：

2016-09-20T07:46:59.685Z got 200 in 1570ms for http://www.stephane-richin.fr/

所以我觉得我的Ngix配置不好：

server {
  listen                *:80;

  server_name           www.stephane-richin.fr;

  access_log            /var/log/nginx/app.dev.access.log;
  error_log             /var/log/nginx/app.dev.error.log;

  location / {
    proxy_pass http://localhost:3000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header X-Forwarded-For $remote_addr;
  }

  location @prerender {
    proxy_set_header X-Prerender-Token xxxxxxxxxxx;

    set $prerender 0;
    if ($http_user_agent ~* "baiduspider|twitterbot|facebookexternalhit|rogerbot|linkedinbot|embedly|quora link previ$
      set $prerender 1;
    }

    if ($args ~ "_escaped_fragment_") {
      set $prerender 1;
    }

    if ($http_user_agent ~ "Prerender") {
      set $prerender 0;
    }

    if ($uri ~* "\.(js|css|xml|less|png|jpg|jpeg|gif|pdf|doc|txt|ico|rss|zip|mp3|rar|exe|wmv|doc|avi|ppt|mpg|mpeg|tif$
        set $prerender 0;
    }

    resolver 8.8.8.8;

    if ($prerender = 1) {
      set $prerender "service.prerender.io";
      rewrite .* /$scheme://$host$request_uri? break;
      proxy_pass http://$prerender;
    }

    if ($prerender = 0) {
      rewrite .* /index.html break;
    }
  }
}

server {
  listen                *:80;

  server_name           stephane-richin.fr;

  location / {

    if ($http_host ~ "^([^\.]+)\.([^\.]+)$"){
      rewrite ^/(.*) http://www.stephane-richin.fr/$1 redirect;
    }

  }
}

任何人都可以帮我解决我的配置Nginx问题？我认为问题是这个。

谢谢！
