如何在javascript/Ajax中添加重试

function retryAjax(url, maxRetries, retryInterval) {
  return new Promise(function(resolve, reject) {
    var retryCount = 0;
    
    function makeRequest() {
      $.ajax({
        url: url,
        success: function(response) {
          resolve(response);
        },
        error: function(xhr, status, error) {
          if (retryCount < maxRetries) {
            retryCount++;
            setTimeout(makeRequest, retryInterval);
          } else {
            reject(error);
          }
        }
      });
    }
    
    makeRequest();
  });
}

// 调用示例
retryAjax('https://example.com/api', 3, 1000)
  .then(function(response) {
    console.log('成功', response);
  })
  .catch(function(error) {
    console.log('失败', error);
  });

axios.interceptors.response.use(undefined, function axiosRetryInterceptor(error) {
  var config = error.config;
  
  // 如果请求失败或达到最大重试次数，则直接返回错误
  if (!config || !config.retry || config.__retryCount >= config.retry) {
    return Promise.reject(error);
  }
  
  // 增加重试计数器
  config.__retryCount = config.__retryCount || 0;
  config.__retryCount++;
  
  // 创建新的Promise，延时指定时间后重新发起请求
  var delay = new Promise(function(resolve) {
    setTimeout(function() {
      resolve();
    }, config.retryDelay || 0);
  });
  
  // 返回Promise，使得axios可以重试请求
  return delay.then(function() {
    return axios(config);
  });
});

// 调用示例
axios.get('https://example.com/api', { retry: 3, retryDelay: 1000 })
  .then(function(response) {
    console.log('成功', response.data);
  })
  .catch(function(error) {
    console.log('失败', error);
  });
