caddy reload --config /etc/caddy/Caddyfile

修改配置文件

vim /etc/caddy/Caddyfile

ex.am.com {
        handle /* {
                reverse_proxy /* localhost:8090
        }
        file_server
}

:::tip

如果不生效则使用 fmt 命令格式化, 然后将得到的内容重新覆盖进文件中

caddy fmt /etc/caddy/Caddyfile

:::

(common_headers) {
    encode {
	gzip
    }
    tls {
        on_demand
    }
}


sk.xx.com {
	import common_headers
        handle /mini-apis/* {
                reverse_proxy /mini-apis/* localhost:8081
        }

        handle /app-apis/* {
                reverse_proxy /app-apis/* localhost:8082
        }

        handle /admin-apis/* {
                reverse_proxy /admin-apis/* localhost:8080
        }
