我有一个看起来像这样的用户界面:
我正在尝试将新创建的行的数据发送到服务器,以便服务器可以保存它。
我正在将 JSON 格式的数据从客户端发送到我的 MVC 应用程序。这是我的ajax请求:
var values = []; // an array with each item being an object/associative array
// more code to get values into variables
for (var i = 0; i < cultures.length; i++) {
var cultureName = cultures[i];
var valueTextBox = $(row).find(...);
var value = $(valueTextBox).val();
var cultureNameAndValue = { 'CultureShortName' : cultureName, 'StringValue' : value };
values.push(cultureNameAndValue);
}
var stringTableRow =
{
'ResourceKeyId': resourceKeyId,
'Key': resourceKeyName,
'CategoryId': categoryId,
'CategoryName': categoryName,
'StringValues': values
};
var stringified = JSON.stringify({ StringTableRow: stringTableRow });
$.ajax('/Strings/JsonCreateNew',
{
cache: false,
async: false,
type: 'POST',
contentType: 'application/json; charset=UTF-8',
data: stringified,
dataType: 'json',
error: SaveNewResourceClientSideHandler.OnError,
success: SaveNewResourceClientSideHandler.OnSuccess
});
这是它发送的数据(如 Firebug 中所示):
{"StringTableRow":{"ResourceKeyId":"","Key":"Foo",
"CategoryId":"1","CategoryName":"JavaScript",
"StringValues":[
{"CultureShortName":"en-US","StringValue":"Something"},
{"CultureShortName":"fr-FR","StringValue":""}]
}}
这是我的服务器端代码:
public ActionResult JsonCreateNew(StringTableRow row)
{
// CreateNewStringTableRow(row);
// return a success code, new resource key id, new category id
// return Json(
new { Success = true, ResourceKeyId = row.ResourceKeyId,
CategoryId = row.CategoryId },
JsonRequestBehavior.AllowGet);
return new EmptyResult();
}
这是我希望传入的 POST 数据绑定到的业务对象:
public class StringTableRow
{
public StringTableRow()
{
StringValues = new List<CultureNameAndStringValue>();
}
public long ResourceKeyId { get; set; }
public string Key { get; set; }
public long CategoryId { get; set; }
public string CategoryName { get; set; }
public IList<CultureNameAndStringValue> StringValues { get; set; }
}
public class CultureNameAndStringValue
{
public string CultureShortName { get; set; }
public string StringValue { get; set; }
}
全球.asax
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
ValueProviderFactories.Factories.Add(new JsonValueProviderFactory());
}
}
问题:
该操作JsonCreateNew
接收一个不为空但所有属性都未初始化的对象,即所有可为空的属性都为空,而值属性为其默认值。因此,即使客户端发送了一个完全有效的 Json 字符串,我也根本没有得到任何数据。
我需要做自定义模型绑定吗?
