cloudflare + B2设置nginx反向代理

使用B2源，cloudflare作为CDN时候，nginx配置文件需要修改，修改如下：

注意：反向代理都在这里设置了，不需要单独在宝塔里加反向代理了。

nginx配置文件

server
{
    listen 80;
    listen 443 ssl;
    listen 443 quic;
    http2 on;
    server_name dd.beiwopan.com;
    index index.php index.html index.htm default.php default.htm default.html;
    #root /www/wwwroot/dd.beiwopan.com;
    #CERT-APPLY-CHECK--START
    # 用于SSL证书申请时的文件验证相关配置 -- 请勿删除
    include /www/server/panel/vhost/nginx/well-known/dd.beiwopan.com.conf;
    #CERT-APPLY-CHECK--END
    include /www/server/panel/vhost/nginx/extension/dd.beiwopan.com/*.conf;
    
    # 👇 把你的代理代码放在这里
location / {
    # 1. 先设置代理目标和请求头
    proxy_pass https://cloudflare-b2.beiwopan123.workers.dev;
    proxy_set_header Host cloudflare-b2.beiwopan123.workers.dev;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header REMOTE-HOST $remote_addr;
    proxy_http_version 1.1;
    proxy_ssl_server_name on;
    proxy_ssl_name cloudflare-b2.beiwopan123.workers.dev;
    proxy_ssl_verify off;

    # 2. 关闭 Nginx 自动生成缓存头（关键！）
    expires off;

    # 3. 👇 隐藏所有不希望透传的上游响应头（包括 B2 元数据）
    proxy_hide_header Cache-Control;
    proxy_hide_header Expires;
    proxy_hide_header Pragma;
    proxy_hide_header Set-Cookie;
    proxy_hide_header X-Cache;

    # 隐藏 Backblaze B2 的私有元信息（可选但推荐）
    proxy_hide_header x-bz-upload-timestamp;
    proxy_hide_header x-bz-content-sha1;
    proxy_hide_header x-bz-file-id;
    proxy_hide_header x-bz-file-name;
    proxy_hide_header x-bz-info-src_last_modified_millis;

    # 4. 添加你自己的标准响应头
    add_header Cache-Control "public, max-age=2592000" always;
    add_header Expires "30d" always;
    add_header X-Content-Type-Options nosniff always;
}
    
    
    #SSL-START SSL相关配置，请勿删除或修改下一行带注释的404规则
    #error_page 404/404.html;
    #HTTP_TO_HTTPS_START
    set $isRedcert 1;
    if ($server_port != 443) {
        set $isRedcert 2;
    }
    if ( $uri ~ /\.well-known/ ) {
        set $isRedcert 1;
    }
    if ($isRedcert != 1) {
        rewrite ^(/.*)$ https://$host$1 permanent;
    }

    error_page 497  https://$host$request_uri;

    #SSL-END

    #ERROR-PAGE-START  错误页配置，可以注释、删除或修改

    #ERROR-PAGE-END

    #PHP-INFO-START  PHP引用配置，可以注释或修改
    #清理缓存规则

    location ~ /purge(/.*) {
        proxy_cache_purge cache_one $host$1$is_args$args;
        #access_log  /www/wwwlogs/dd.beiwopan.com_purge_cache.log;
    }
	#引用反向代理规则，注释后配置的反向代理将无效
	include /www/server/panel/vhost/nginx/proxy/dd.beiwopan.com/*.conf;

	#include enable-php-00.conf;
    #PHP-INFO-END

    #REWRITE-START URL重写规则引用,修改后将导致面板设置的伪静态规则失效
    include /www/server/panel/vhost/rewrite/dd.beiwopan.com.conf;
    #REWRITE-END

    #禁止访问的文件或目录
    location ~ ^/(\.user.ini|\.htaccess|\.git|\.env|\.svn|\.project|LICENSE|README.md)
    {
        return 404;
    }

    #一键申请SSL证书验证目录相关设置
    location ~ \.well-known{
        allow all;
    }

    #禁止在证书验证目录放入敏感文件
    if ( $uri ~ "^/\.well-known/.*\.(php|jsp|py|js|css|lua|ts|go|zip|tar\.gz|rar|7z|sql|bak)$" ) {
        return 403;
    }

    

    
    access_log  /dev/null;
    error_log  /www/wwwlogs/dd.beiwopan.com.error.log;
}

这是整个宝塔的配置文件内容，根据自己的修改。

cloudflare配置CDN

这个设置不好贴出来，详情看账户的CDN规则设置把。
