jquery - 使用 "application/json; charset=utf-8"将 ajax post 发送到 mvc 从 vs web 开发服务器返回错误 500

Question

我正在尝试将 javascript 对象发送到 VS 2010 中的 MVC 方法。使用 VS Web 服务器。

    $.ajax({ 
            type: "POST",
            url: "@Url.Action("Filter", "Grid")",
            dataType: "json", 
            data: {"data": JSON.stringify(filtersData) }, 
            contentType: "application/json; charset=utf-8", 
            traditional: true,
            success: function (data) { 
                alert("ok"); 
            },
            error:function (xhr, ajaxOptions, thrownError) { 
                alert(xhr.status); 
                alert(thrownError); 
            }
        }); 

添加 contentType 参数时会导致 500 错误。我做错了什么？

这最终奏效了:

    var filtersApplyData = GetFiltersApplyData@(Model.PropertyID)();
    var data = JSON.stringify({data: filtersApplyData, classID: @(Model.ClassID)});
    $.ajax({ 
            type: "POST",
            url: "@Url.Action("ApplyFilters", "Grid")",
            data: data, 
            contentType: "application/json", 
            traditional: true,
            success: function (data) { 
                $("#grid").html(data);
            },
            error:function (xhr, ajaxOptions, thrownError) { 
                alert(xhr.status); 
                alert(ajaxOptions); 
                alert(thrownError); 
            }
    });
