在Tampermonkey中如何实现对多个链接的并发GET请求并依次判断返回结果？

function fetchUrl(url) {
  return new Promise((resolve, reject) => {
    GM_xmlhttpRequest({
      method: "GET",
      url: url,
      onload: (response) => {
        resolve({ url: url, data: response.responseText });
      },
      onerror: (error) => {
        reject(error);
      }
    });
  });
}

async function main() {
  const urls = [
    "https://example.com/1",
    "https://example.com/2",
    "https://example.com/3"
  ];

  const promises = urls.map(url => fetchUrl(url));

  try {
    const result = await Promise.race(promises);
    // 判断结果是否满足条件，例如：
    if (result.data.includes("success")) {
      console.log("条件满足，结果：", result);
      return result;
    } else {
      console.log("第一个请求不满足条件");
      // 可在此处处理后续请求，或直接返回
      return null; // or handle other results
    }
  } catch (error) {
    console.error("请求错误：", error);
    return null;
  }
}


main();
