Question

我在mvc4中使用ajax post到controller，

我的代码控制器是：

[HttpPost]
public JsonResult UpdateAllSettings(int PresetID,List<CustomerAjaxServiceSettingPoco> customerServiceSettings)
{

和CustomerAjaxServiceSettingPoco是：

 public class CustomerAjaxServiceSettingPoco
    {
        public int ID { get; set; }
        public string ClientSettingValue { get; set; }
    }

我的javascript是：

 var customerServiceSettings = new Array();
        $('.settings_user').each(function () {
            customerServiceSettings[customerServiceSettings.length] = { 'ID': $(this).data('settingsid'), 'ClientSettingValue': $(this).val() };
        });



$.ajax({
        url: '/Services/UpdateAllSettings?PresetID=' + PresetID,
        type: 'POST',
        data: { 'customerServiceSettings':JSON.stringify( customerServiceSettings) },
        traditional: true,
        dataType: 'json',
        success: function (result) {
            do...
        }
    });

仍处于调试模式我得到“customerServiceSettings count = 0”和“PresetID = 1” 我究竟做错了什么？火灾中的帖子来源是：参数 customerServiceSettings [{“ID”：1，“ClientSettingValue”：“False”}，{“ID”：2，“ClientSettingValue”：“False”}，{“ID”：3，“ClientSettingValue”：“False”}， { “ID”：4 “ClientSettingValue”： “错误”}，{ “ID”：5 “ClientSettingValue”： “正确”}，{ “ID”：6， “ClientSettingValue”： “正确”}，{” ID “：9”，ClientSettingValue “：” 正确 “}，{” ID “：10”，ClientSettingValue “：” 错误 “}，{” ID “：11”，ClientSettingValue “：” 正确 “}，{” ID” ：12， “ClientSettingValue”： “正确”}，{ “ID”：13， “ClientSettingValue”： “错误”}，{ “ID”：14， “ClientSettingValue”： “正确”}，{ “ID”：15 “ClientSettingValue”： “正确”}，{ “ID”：67， “ClientSettingValue”： “”}，{ “ID”：68， “ClientSettingValue”： “”}，{ “ID”：69， “ClientSettingValue” ： “”}，{ “ID”：70， “ClientSettingValue”： “”}，{ “ID”：21， “ClientSettingValue”： “正确”}，{ “ID”：22， “ClientSettingValue”： “真” }，{ “ID”：23， “ClientSettingValue”： “错误”}，{ “ID”：24， “ClientSettingValue”： “正确”}，{ “ID”：25， “ClientSettingValue”： “错误”}， { “ID”：27， “ClientSettingValue”： “错误”}，{ “ID”：28， “ClientSettingValue”： “错误”}，{ “ID”：71， “ClientSettingValue”： “”}，{“ID “：72，” ClientSettingValue “：”“}] 资源 customerServiceSettings =％5B％7B％22ID％22％3A1％2C％22ClientSettingValue％22％3A％22False％22％7D％2C％7B％22ID％22％3A2％2C％22ClientSettingValue％22％3A％22False％22％7D ％2C％7B％22ID％22％3A3％2C％22ClientSettingValue％22％3A％22False％22％7D％2C％7B％22ID％22％3A4％2C％22ClientSettingValue％22％3A％22False％22％7D％2C ％7B％22ID％22％3A5％2C％22ClientSettingValue％22％3A％22True％22％7D％2C％7B％22ID％22％3A6％2C％22ClientSettingValue％22％3A％22True％22％7D％2C％7B ％22ID％22％3A9％2C％22ClientSettingValue％22％3A％22True％22％7D％2C％7B％22ID％22％3A10％2C％22ClientSettingValue％22％3A％22False％22％7D％2C％7B％22ID ％22％3A11％2C％22ClientSettingValue％22％3A％22True％22％7D％2C％7B％22ID％22％3A12％2C％22ClientSettingValue％22％3A％22True％22％7D％2C％7B％22ID％22 ％3A13％2C％22ClientSettingValue％22％3A％22False％22％7D％2C％7B％22ID％22％3A14％2C％22ClientSettingValue％22％3A％22True％22％7D％2C％7B％22ID％22％3A15 ％2C％22ClientSettingValue％22％3A％22True％22％7D％2C％7B％22ID％22％3A67％2C％22ClientSettingValue％22％3A％22％22％7D％2C％7B％22ID％22％3A68％2C ％22ClientSettingValue％22％3A％22％22％7D％2C％7B％22ID％22％3A69％2C％22ClientSettingValue％22％3A％22％22 ％7D％2C％7B％22ID％22％3A70％2C％22ClientSettingValue％22％3A％22％22％7D％2C％7B％22ID％22％3A21％2C％22ClientSettingValue％22％3A％22True％22％7D ％2C％7B％22ID％22％3A22％2C％22ClientSettingValue％22％3A％22True％22％7D％2C％7B％22ID％22％3A23％2C％22ClientSettingValue％22％3A％22False％22％7D％2C ％7B％22ID％22％3A24％2C％22ClientSettingValue％22％3A％22True％22％7D％2C％7B％22ID％22％3A25％2C％22ClientSettingValue％22％3A％22False％22％7D％2C％7B ％22ID％22％3A27％2C％22ClientSettingValue％22％3A％22False％22％7D％2C％7B％22ID％22％3A28％2C％22ClientSettingValue％22％3A％22False％22％7D％2C％7B％22ID ％22％3A71％2C％22ClientSettingValue％22％3A％22％22％7D％2C％7B％22ID％22％3A72％2C％22ClientSettingValue％22％3A％22％22％7D％5D

Answer 1

尝试添加 contentType 和stringify整个对象，如下所示：

$.ajax({
        type: 'POST',
        dataType: 'json',
        url: '...',
        data: JSON.stringify({ steps: ['1', '2', '3'] }),
        contentType: 'application/json; charset=utf-8',
});

将对象数组发送到mvc控制器
