javascript - jQuery post 不会将数据发布到 ASP.NET API Controller

Question

我有一次通过 jquery post 将数据发送到 ASP.NET Controller 的噩梦。这是 JSON.stringify 后数据的样子:

[{"scheduleTaskID":"203","task":"Permit","baselineDate":"4/6/2005 8:00:00 AM","scheduledDate":"4/6/2005 8:00:00 AM","actualDate":"4/6/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"195","task":"Office Files","baselineDate":"7/13/2005 8:00:00 AM","scheduledDate":"7/13/2005 8:00:00 AM","actualDate":"7/13/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"196","task":"Foundation","baselineDate":"7/27/2005 8:00:00 AM","scheduledDate":"7/27/2005 8:00:00 AM","actualDate":"8/13/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"197","task":"Framing","baselineDate":"8/5/2005 8:00:00 AM","scheduledDate":"8/5/2005 8:00:00 AM","actualDate":"8/23/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"198","task":"Finishes Exterior","baselineDate":"8/26/2005 8:00:00 AM","scheduledDate":"8/26/2005 8:00:00 AM","actualDate":"9/14/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"199","task":"Drywall","baselineDate":"9/2/2005 8:00:00 AM","scheduledDate":"9/2/2005 8:00:00 AM","actualDate":"9/16/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"200","task":"Flooring","baselineDate":"9/1/2005 8:00:00 AM","scheduledDate":"9/1/2005 8:00:00 AM","actualDate":"9/20/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"201","task":"General Finish","baselineDate":"9/12/2005 8:00:00 AM","scheduledDate":"9/12/2005 8:00:00 AM","actualDate":"","finishedDate":"","selected":"on"},{"scheduleTaskID":"202","task":"Final PDI","baselineDate":"10/11/2005 8:00:00 AM","scheduledDate":"10/11/2005 8:00:00 AM","actualDate":"","finishedDate":"","selected":"on"},{"scheduleTaskID":"203","task":"Permit","baselineDate":"4/6/2005 8:00:00 AM","scheduledDate":"4/6/2005 8:00:00 AM","actualDate":"4/6/2005 8:00:00 AM","finishedDate":"","selected":"on"},{}]

这就是我尝试传递数据的方式:

$.post("/api/update/", JSON.stringify( array ), alert('success'), 'json');

这是我的 ASP.NET API Controller :

[HttpPost]
        public dynamic Post(List<CellModel> cells)
        {
        }

这就是 CellModel:

public class CellModel
    {
        public string scheduleTaskID { get; set; }
        public string task { get; set; }
        public string baselineDate { get; set; }
        public string scheduledDate { get; set; }
        public string actualDate { get; set; }
        public string finishedDate { get; set; }
        public bool selected { get; set; }
    }

当我在 public dynamic Post(List<CellModel> cells) 之后在 Controller 中放置断点时它说细胞是cells Count = 0 ...我把return false;在我的帖子调用查看网络调用后，它显示状态代码为 301 永久移动:

这就是我获取这些数据的方式:

$("#form").submit(function (event) {
            var array = [];
            $('#form > table > tbody  > tr').each(function (elem) {
                var item = {
                    scheduleTaskID: $(this).find("td > #scheduleTaskID").val(),
                    task: $(this).find("td > #task").val(),
                    baselineDate: $(this).find("td > #baselineDate").val(),
                    scheduledDate: $(this).find("td > #scheduledDate").val(),
                    actualDate: $(this).find("td > #actualDate").val(),
                    finishedDate: $(this).find("td > #finishedDate").val(),
                    selected: $(this).find("td > #selected").val(),
                };
                array.push(item);
            });

            $.post("/api/update/", JSON.stringify(array), alert('success'), 'json');
            return false;

        });

POST将直接 JSON 数组发送到 MVC Controller 不起作用。解决方案是使用长格式 AJAX jQuery 方法，包括 traditional:true 选项，并以不同的方式构建 JSON 数据和模型 - 请参阅 this answer .

关于模型: Controller 操作的参数不应该是数组 - 它应该是一个模型类，其中包含和数组成员 - 当然，您的 JSON 应该反射(reflect)此结构。
