【help】在搭建cloudflare反代后出现部分cloudflare网站报错1003

[123xiaoxiao321]

cf的worker我是在网上抄的，原代码为
addEventListener('fetch', event => {
event.respondWith(handleRequest(event.request));
});

async function handleRequest(request) {
try {
const url = new URL(request.url);

  // 如果访问根目录，返回HTML
  if (url.pathname === "/") {
      return new Response(getRootHtml(), {
          headers: {
              'Content-Type': 'text/html; charset=utf-8'
          }
      });
  }

  // 从请求路径中提取目标 URL
  let actualUrlStr = decodeURIComponent(url.pathname.replace("/", ""));

  // 判断用户输入的 URL 是否带有协议
  actualUrlStr = ensureProtocol(actualUrlStr, url.protocol);

  // 保留查询参数
  actualUrlStr += url.search;

  // 创建新 Headers 对象，排除以 'cf-' 开头的请求头
  const newHeaders = filterHeaders(request.headers, name => !name.startsWith('cf-'));

  // 创建一个新的请求以访问目标 URL
  const modifiedRequest = new Request(actualUrlStr, {
      headers: newHeaders,
      method: request.method,
      body: request.body,
      redirect: 'manual'
  });

  // 发起对目标 URL 的请求
  const response = await fetch(modifiedRequest);
  let body = response.body;

  // 处理重定向
  if ([301, 302, 303, 307, 308].includes(response.status)) {
      body = response.body;
      // 创建新的 Response 对象以修改 Location 头部
      return handleRedirect(response, body);
  } else if (response.headers.get("Content-Type")?.includes("text/html")) {
      body = await handleHtmlContent(response, url.protocol, url.host, actualUrlStr);
  }

  // 创建修改后的响应对象
  const modifiedResponse = new Response(body, {
      status: response.status,
      statusText: response.statusText,
      headers: response.headers
  });

  // 添加禁用缓存的头部
  setNoCacheHeaders(modifiedResponse.headers);

  // 添加 CORS 头部，允许跨域访问
  setCorsHeaders(modifiedResponse.headers);

  return modifiedResponse;

} catch (error) {
// 如果请求目标地址时出现错误，返回带有错误消息的响应和状态码 500（服务器错误）
return jsonResponse({
error: error.message
}, 500);
}
}

// 确保 URL 带有协议
function ensureProtocol(url, defaultProtocol) {
return url.startsWith("http://") || url.startsWith("https://") ? url : defaultProtocol + "//" + url;
}

// 处理重定向
function handleRedirect(response, body) {
const location = new URL(response.headers.get('location'));
const modifiedLocation = /${encodeURIComponent(location.toString())};
return new Response(body, {
status: response.status,
statusText: response.statusText,
headers: {
...response.headers,
'Location': modifiedLocation
}
});
}

// 处理 HTML 内容中的相对路径
async function handleHtmlContent(response, protocol, host, actualUrlStr) {
const originalText = await response.text();
const regex = new RegExp('((href|src|action)=["'])/(?!/)', 'g');
let modifiedText = replaceRelativePaths(originalText, protocol, host, new URL(actualUrlStr).origin);

return modifiedText;
}

// 替换 HTML 内容中的相对路径
function replaceRelativePaths(text, protocol, host, origin) {
const regex = new RegExp('((href|src|action)=["'])/(?!/)', 'g');
return text.replace(regex, $1${protocol}//${host}/${origin}/);
}

// 返回 JSON 格式的响应
function jsonResponse(data, status) {
return new Response(JSON.stringify(data), {
status: status,
headers: {
'Content-Type': 'application/json; charset=utf-8'
}
});
}

// 过滤请求头
function filterHeaders(headers, filterFunc) {
return new Headers([...headers].filter(([name]) => filterFunc(name)));
}

// 设置禁用缓存的头部
function setNoCacheHeaders(headers) {
headers.set('Cache-Control', 'no-store');
}

// 设置 CORS 头部
function setCorsHeaders(headers) {
headers.set('Access-Control-Allow-Origin', '');
headers.set('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE');
headers.set('Access-Control-Allow-Headers', '');
}

// 返回根目录的 HTML
function getRootHtml() {
return `
