反向代理将 url 重定向到子域

Question

我正在尝试将帮助 URL 从 example.com/help 重写为 help.example.come。 我尝试了很多配置 nginx 的方法，但是当我请求 example.com/help 时，会出现片刻内容，然后它会重定向到带有 help.example.come url 的主页。

我在工作中使用了 nuxtjs v2.13.3 和 nginx。这是我的 nginx 配置文件：

1. nuxtjs 服务器块

    server {
        listen 80;
        index index.html;
        root /var/www/site/dist/;
        server_name  example.come;
    
        location / {
            proxy_pass http://127.0.0.1:3000;
        }
    
    
        # help redirecting...
        location ~ ^/help/(.*)$ {
            return 301 $scheme://help.example.come/$1;
        }
    }

1. 子域服务器块

    server {
        listen 80;
        server_name help.example.come;
    
        location / {
            proxy_pass http://127.0.0.1:3000/help/;
        }
    
        location /_nuxt/ {
            rewrite /help/(.*) /$1;
            proxy_pass http://127.0.0.1:3000/_nuxt/;
        }
    
        location ~* \.(jpg|jpeg|gif|png|ico)$ {
            rewrite ^/_nuxt(/.*) $1;
            root /var/www/site/dist/;
            expires 30d;
        }
    }

Answer 1

不确定这是否完全符合您的需要，但是：

example.com/help/uri1/uri2 上的传入请求将被重定向到 help.example.com/help/uri1/uri2

在将请求代理到后端之前，我们正在重写 request_uri

rewrite ^/help(.*)$ /_nuxt$1 break;

在这里，我们将/help/ 替换为/_nuxt/。

这是我的测试配置：

server {                                                                                
    listen 80;                                                                        
    server_name example.com;                                                                                    
    location /help {                                                                    
      #return 301 http://help.example.com$request_uri;
      rewrite ^/help(.*)$ /_nuxt$1 break;                                            
      proxy_pass http://127.0.0.1:3000/;                            
    }                                                                                   
}                                                                                       
                                                                                        
                                                                                        
                                                                                        
server {
