首先要感谢https://loc.xiu.ee/thread-1171965-1-1.html
次改良版本也是基于此，没什么技术含量。
研究了下dz的源代码，查看校验逻辑要求Referer参数也一致。
提醒：使用来源不明的非官方反代有被窃取数据的风险，cfworker使用门槛很低，推荐自己搭建！
附上我自己的反代示例： https://loc.xiu.ee
稍作修改即可，顺便完善了手机端的样式:

1.修复头像
2.修复交易帖显示缺失
完整代码如下：
- /**
- * write by 西柚论坛 https://www.xiubbs.com
- */
- 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);
- headers.set("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/113.0.0.0 Safari/537.36");
- //处理头像的302跳转，处理编辑帖子之后的报错
- let redirect = "manual";
- if(url.href.indexOf("/uc_server/") > -1){
- redirect = "follow";
- }
- const param = {
- method: request.method,
- headers: headers,
- body: request.body,
- redirect: redirect
- }
- let response = await fetch(url, param);
- // 检查响应头中的内容类型
- const contentType = response.headers.get('content-type');
- if (contentType && contentType.includes('text')) {
- // 如果是文本类型，替换响应主体中的URL
- let responseBody = await response.text();
- responseBody = await handleResBody(request,responseBody);
- // 复制响应对象并更新它的属性
- let headers = await handleResHeader(response);
- return new Response(responseBody, {
- status: response.status,
- statusText: response.statusText,
- headers: headers
- });
- } else {
- // 如果不是文本类型，直接返回响应对象
- return response;
- }
- }
- async function handleResBody(request, responseBody){
- responseBody = responseBody.replace(target_url_reg, new URL(request.url).hostname);
- responseBody = responseBody.replace("<head>", '<head>\n<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">');
- responseBody = responseBody.replace("</head>", '<link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/gh/lifespy/[email protected]/css/responsive.css">\n</head>');
- responseBody = responseBody.replace("</body>", '<script src="//cdn.jsdelivr.net/gh/lifespy/[email protected]/js/polish.js" type="text/javascript"></script>\n</body>');
-
- //自用
- responseBody = responseBody.replace('<li id="mn_N12a7" ><a href="misc.php?mod=ranklist" hidefocus="true" title="Ranklist" >排行榜<span>Ranklist</span></a></li>', '<li id="mn_N12a7"><a href="misc.php?mod=ranklist" hidefocus="true" title="Ranklist">排行榜<span>Ranklist</span></a></li><li id="mn_N12a7"><a href="https://www.xiubbs.com" hidefocus="true" title="西柚论坛">西柚论坛<span>西柚论坛</span></a></li>');
- return responseBody;
- }
- async function handleResHeader(resp){
- let headers = new Headers(resp.headers);
- headers.set('Access-Control-Allow-Origin', '*');
- headers.set('Access-Control-Allow-Methods', 'GET');
- headers.set('Access-Control-Allow-Headers', 'Content-Type');
- return headers;
- }
