nginx 重定向 proxy_pass

nginx redirect with proxy_pass

我在我的本地机器上有一个适用于 nginx 运行 的有效代理服务器配置。它是 docker 中的 运行,服务于我的幽灵博客本地实例的 node.js 实例也是如此。

因为我刚刚从一个旧的博客引擎迁移过来,所以我的 url 现在不同了,所以我想将 nginx 配置为 return 301(永久)重定向到新的 url方案。我尝试同时使用 rewriteproxy_redirect,在这两种情况下我都收到 401 错误。这是我的 default.conf

# If we receive X-Forwarded-Proto, pass it through; otherwise, pass along the
# scheme used to connect to this server
map $http_x_forwarded_proto $proxy_x_forwarded_proto {
  default $http_x_forwarded_proto;
  ''      $scheme;
}
# If we receive Upgrade, set Connection to "upgrade"; otherwise, delete any
# Connection header that may have been passed to this server
map $http_upgrade $proxy_connection {
  default upgrade;
  '' close;
}

                 '"$request" $status $body_bytes_sent '
                 '"$http_referer" "$http_user_agent"';

server {
    server_name _; # This is just an invalid value which will never trigger on a real hostname.
    listen 80;
    access_log /var/log/nginx/access.log vhost;
    return 503;
}
upstream localhost {
    server 172.17.0.3:2368;
}
server {
    server_name localhost;
    listen 80;
    access_log /var/log/nginx/access.log vhost;
    location / {
#        rewrite "^/archive/(\d{4}/\d{2}/\d{2}/.+)\.(?:aspx|html)$" / break; 
        proxy_pass http://localhost;
#        proxy_redirect "-*/archive/(\d{4}/\d{2}/\d{2}/.+)\.(?:aspx|html)" /;
    }
}

如果我取消对重写或 proxy_redirect 指令的注释,什么都不会发生 - 请求被转发到 node.js,我得到一个 404。

如果我像这样使用多个位置指令:

location /archive/ {
    rewrite "^/archive/(\d{4}/\d{2}/\d{2}/.+)\.(?:aspx|html)$" / break; 
}    
location / {
    proxy_pass http://localhost;
}

我从 nginx 收到一个 404,请求从未到达 node.js。

您的 rewrite 在单独的位置块中,应使用 last 而不是 break(有关详细信息,请参阅 this):

location /archive/ {
    rewrite "^/archive/(\d{4}/\d{2}/\d{2}/.+)\.(?:aspx|html)$" / last;
}  

proxy_redirect 不重写请求,它重写来自上游的 3xx 响应。有关详细信息,请参阅 this

我看不出你的任何一种 rewrite 方法有什么问题,当然除非正则表达式是错误的。您可以尝试添加 rewrite_log on; 来逐步记录重写。有关详细信息,请参阅 this
