3. 💡 解决方案

// 修复后的代码：增加重试机制、错误捕获与接口状态检查
async function sendChatRequest(message) {
  const url = "https://www.dmxapi.cn/v1/chat/completions";
  const maxRetry = 3;
  let currentRetry = 0;

  while (currentRetry < maxRetry) {
    try {
      const response = await fetch(url, {
        method: "POST",
        headers: {
          "Content-Type": "application/json",
          "Authorization": "Bearer YOUR_API_KEY" // 替换为有效密钥
        },
        body: JSON.stringify({ messages: [{ role: "user", content: message }] })
      });

      // 处理500错误：重试或反馈
      if (response.status === 500) {
        currentRetry++;
        if (currentRetry >= maxRetry) {
          throw new Error("服务器持续500错误，请稍后重试或联系管理员");
        }
        await new Promise(resolve => setTimeout(resolve, 1000 * currentRetry)); // 递增重试间隔
        continue;
      }

      if (!response.ok) {
        throw new Error(`请求失败，状态码：${response.status}`);
      }

      return await response.json();
    } catch (error) {
      if (currentRetry >= maxRetry) {
        throw new Error(`网络请求最终失败：${error.message}`);
      }
      currentRetry++;
    }
  }
}
