解决docker部署的nginx重定向请求时端口号丢失的问题：location root配置示例

错误配置示范

按照网上帖子的说法，配置这行即可：

proxy_set_header Host $host:$server_port;

server {

    listen 80;
    server_name localhost;

    client_max_body_size 100m;

    charset utf-8;

    location /gantt {
        proxy_set_header Host $host:$server_port;
        root /usr/share/nginx/gantt;
    }
}

正确配置
