我有一个WebMethod,其参数定义为DateTime。当我打电话给那个
webservice,我收到此错误:
在 System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializePrimitiveObject() 在 System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(的Int32 深度) System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeDictionary(的Int32 深度) System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(的Int32 深度) System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(字符串 输入,Int32 depthLimit, JavaScriptSerializer序列化程序) System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer 序列化器,字符串输入,类型类型, Int32 depthLimit)at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize [T](字符串 输入) System.Web.Script.Services.RestHandler.GetRawParamsFromPostRequest(HttpContext的 上下文,JavaScriptSerializer 序列化器) System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData,HttpContext context)at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext的 context,WebServiceMethodData methodData)“
这是我的WebService:
/// <summary>
/// Summary description for AgendamentoService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class AgendamentoService : System.Web.Services.WebService
{
public AgendamentoService()
{
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public CompromissoWekCalendarVO[] GetCompromissos(int id_pessoa, DateTime start, DateTime end)
{
bo.CompromissoBO compBO = new bo.CompromissoBO();
return compBO.Get(id_pessoa,start, end).ToArray();
}
}
在这里,我的客户端代码:
var params = '{id_pessoa: "' + id_pessoa + '", start:/Date('+ start.getTime()+')/, end:/Date(' + end.getTime()+')/}';
$.ajax(
{
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
url: '<%= this.ResolveClientUrl("~/services/misc/AgendamentoService.asmx/GetCompromissos") %>',
data: params,
success: function (json) {
if ($.isArray(json.d)) {
$.each(json.d, function(key, value) {
value.start = getJsonDate(value.start);
value.end = getJsonDate(value.end);
});
}
callback(json.d);
}
});
'start'和'end'时间是两个javascript'Date'对象。

这是因为ASP.NET Ajax期望有特定的日期/时间有线格式 - 它的形式为"\/Date(x)\/"
,其中x是自1970年1月1日UTC午夜以来经过的ms数。基本上,你需要使用一些辅助函数,在调用服务时将JS日期转换为所需的格式(反之亦然,日期/时间json从服务到JS日期/时间对象)。
因此,您必须更改代码片段,例如
`'", start:/Date('+ start.getTime()+')/, end...`
到
'", start:"\\\/Date(' + this.getTime() + ')\\\/", end...'
使用以下插件的最快方式:

这对我有用:
JSON.stringify(new Date())
这会将其转换为“2014-06-04T14:26:27.129Z”之类的格式,我的网络服务很乐意接受DateTime参数。
