指南

Caddy 是一款基于 Go 语言编写的强大且可扩展的平台，可以给你的站点、服务和应用程序提供服务。

场景​

使用 API 配置 Caddy​

参考官方文档：https://caddyserver.com/docs/quick-starts/api

列出目录文件​

file_server browse

指定反代目录​

在实践中，我们可能只想对 API 请求使用反向代理，即基本路径为/api/

file_server
reverse_proxy /api/* 127.0.0.1:9005

模板​

Caddy 官方提供了丰富的模板供用户参考、学习和讨论。

这里列出几种典型的应用场景：

域名 + 本地 php-fpm​

domain.com {
	root * /var/www/domain.com
	encode zstd gzip
	file_server
	php_fastcgi unix//run/php/php7.4-fpm.sock
}

域名 + 代理​

# 代理到本机
youdomain.example.com {
    reverse_proxy https://localhost:9090 {
        transport http {
            tls_insecure_skip_verify
        }
    }
}

# 代理到容器
collabora.example.com {
  encode gzip

  reverse_proxy https://collabora:9980 {
    transport http {
      tls_insecure_skip_verify
    }
  }
}

IP + php-fpm 容器​

:80 {
	root * /srv/public
	encode gzip
	php_fastcgi php:9000
	file_server
}

IP + 多端口访问​

:8080 {
	respond "I am 8080"
}

:8081 {
	respond "I am 8081"
}
