如何向post方法的ajax调用中添加参数

var formData = new FormData();
formData.append('name', 'John');

$.ajax({
  url: '/api/endpoint',
  type: 'POST',
  data: formData,
  processData: false,
  contentType: false,
  success: function(response) {
    // 处理成功响应
  },
  error: function(xhr, status, error) {
    // 处理错误响应
  }
});

var data = {
  name: 'John'
};

$.ajax({
  url: '/api/endpoint',
  type: 'POST',
  data: JSON.stringify(data),
  contentType: 'application/json',
  success: function(response) {
    // 处理成功响应
  },
  error: function(xhr, status, error) {
    // 处理错误响应
  }
});
