nginx proxy_pass 正在设置响应端口

Question

我的 Nginx 配置类似于：

server {
    listen 80;
    listen 443;
    server_name api.mysite.dev;

    location / {

        proxy_set_header Host "api.mysite.dev";
        proxy_set_header X-Real-IP $remote_addr;
        proxy_pass  $scheme://127.0.0.1:8001;
    }

}

server {
    listen 80;
    listen 443;
    server_name mysite.dev www.mysite.dev;

    # Forward all /api/ requests ti api.mysite.dev
    # sadly need to keep this around for backwards compatibility
    location /api/ {
        proxy_set_header Host "api.mysite.dev";
        proxy_set_header X-Real-IP $remote_addr;
        proxy_pass $scheme://127.0.0.1:8001/;

    }
    # The proxy_pass here ends up putting the port (8002) in the response URL.
    location / {
        proxy_set_header Host "www.mysite.dev";
        proxy_set_header X-Real-IP $remote_addr;
        proxy_pass  $scheme://127.0.0.1:8002;
    }
}

因此，正如评论中所述，当我请求 www.mysite.dev 时，我的浏览器将转发到 www.mysite.dev:8002。你知道我在这里做错了什么吗？

提前致谢！

您必须设置以下选项：

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $host;

这是一个有效的示例：

    server {
        listen 80;
        listen 443;
        server_name api.mysite.dev;

        location /api/ {
            proxy_pass http://127.0.0.1:8001/;
            proxy_redirect off;

            proxy_set_header X-Forwarded-Host $host;
            proxy_set_header Host "api.mysite.dev";
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Real-IP $remote_addr;
        }
    }
