caddy2网站反向代理配置文件demo

异世界百科配置文件的例子

www.isekai.cn isekai.cn {
    encode gzip
    #设置证书
    tls /xxx/isekai.pem /xxx/isekai.key
    #判定条件：是否要重定向到标准域名
    @should_redirect_index {
        not host www.isekai.cn
        not host static-www.isekai.cn
    }
    #判定条件：是否要重定向到https
    @can_redirect_https {
        protocol http
        not header User-Agent *CacheBot*
        not path /api/uc.php*
    }
    #路由内容，如果有一个已经执行，就不会继续执行下一个
    route {
        #重定向到指定页面
        redir @should_redirect_index https://www.isekai.cn{uri} permanent

        redir @can_redirect_https https://{host}{uri} permanent

        redir /IsekaiBook https://book.isekai.cn/ permanent
        #反向代理配置
        reverse_proxy {
            #upstream地址设定，如果是https要加上https://
            to localhost:114 localhost:514
            #使用第一个可以连接的地址，相当于把后面的当作backup
            lb_policy first
            #测试连通性的页面地址，必须设置，不然不会自动把down的主机从upstream列表中移除
            health_path /test.php
            #要传输给upstream的header
            header_up Host {host}
            header_up X-Real-IP {remote_host}
            header_up X-Forwarded-For {remote_host}
            header_up X-Forwarded-Proto {scheme}
            header_up X-NginX-Proxy true
            #编辑upstream返回的header，去掉server
            header_down -server
        }
    }
}

另：原先的nginx配置文件如下

upstream isekai_wiki {
	server localhost:114;
	server localhost:514 backup;
}

server {
	listen 80 default_server;
	listen 443 ssl http2 default_server;
	
	ssl_certificate /xxx/isekai.pem;
	ssl_certificate_key /xxx/isekai.key;

	server_name www.isekai.cn isekai.cn;

	location / {
		#轻小说
		rewrite ^/IsekaiBook$ https://book.isekai.cn/ permanent;

		set $flag 0;
		if ($scheme = http) {
			set $flag "${flag}1";
		}
		
		if ($request_method = GET) {
			set $flag "${flag}2";
