Nginx 代理 : rewrite rule for root request

Question

我在 80 端口上安装了 nginx，在 nginx 后面的 2368 端口上安装了一个节点应用程序

nginx 配置是这样的

server {
    server_name domain.com www.domain.com;
    listen 80; 
    location / {
        proxy_pass http://localhost:2368;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_buffering off;
    } 
}

此配置完全按预期工作。比如/请求变成http://localhost:2368/，/post/mypost变成http://localhost:1234/post/mypost 等

我想要的是只有 / 请求变成了 http://localhost:2368/latestpost/。所有其他请求的处理方式与上面的示例相同。谢谢!

你可以使用 rewrite 指令:

server {
    server_name domain.com www.domain.com;
    listen 80; 
    location / {
        rewrite ^/$ /latestpost/ break;
        proxy_pass http://localhost:2368;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_buffering off;
    } 
}

或在单独的位置:

server {
    server_name domain.com www.domain.com;
    listen 80;
    location = / {
        rewrite ^.* /latestpost/;
    }
    location / {
        proxy_pass http://localhost:2368;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_buffering off;
    } 
}

第二种变体的效率稍高一些，因为它不会尝试重写每个请求。但我猜差异将不明显。
