又弄了一个演示：https://loc.513513.xyz

1.修复头像
2.修复交易帖显示缺失
直接上代码：
/**

addEventListener('fetch', event => {
event.respondWith(handleRequest(event.request));
});
// 准备反代的目的域名
let target_url = "https://hostloc.com";
// 要替换内容的正则表达式
let target_url_reg = /(?<=\/\/).*?hostloc\.com/g;
async function handleRequest(request) {
let url = new URL(request.url);
url.hostname = new URL(target_url).hostname;
// 复制请求对象并更新它的属性
let headers = new Headers(request.headers);
headers.set("Referer", target_url);

//处理头像的302跳转，处理编辑帖子之后的报错

}
}

搞了一个星期的反代discuz都不能发帖，看到你的帖子马上就解决了。
不过还有点地方可以完善。
如果反代的论坛使用了cloudflare需要加上下面3行
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_http_version 1.1;
如果反代的网站都是用了ssl需要加上下面两行
proxy_ssl_name $host;
proxy_ssl_server_name on;
