如何在ajax url中发送很长的数据？

var data = {
  // 长数据...
};

$.ajax({
  url: "your-url",
  type: "POST",
  data: JSON.stringify(data),
  contentType: "application/json",
  success: function(response) {
    // 处理响应
  },
  error: function(xhr, status, error) {
    // 处理错误
  }
});

var formData = new FormData();
formData.append("data", longData);

$.ajax({
  url: "your-url",
  type: "POST",
  data: formData,
  processData: false,
  contentType: false,
  success: function(response) {
    // 处理响应
  },
  error: function(xhr, status, error) {
    // 处理错误
  }
});

function sendLongData(data, index) {
  var chunkSize = 100; // 每次发送的数据块大小
  var start = index * chunkSize;
  var end = Math.min(start + chunkSize, data.length);
  var chunk = data.slice(start, end);

  $.ajax({
    url: "your-url",
    type: "POST",
    data: chunk,
    success: function(response) {
      if (end < data.length) {
        sendLongData(data, index + 1); // 继续发送下一部分数据
      } else {
        // 全部发送完成
      }
    },
    error: function(xhr, status, error) {
      // 处理错误
    }
  });
}

sendLongData(longData, 0);
