我正在尝试从我的WinForms应用程序将对象列表发布到我的ASP.NET MVC 4网站。我已经测试了发布一个对象,它可以工作,但是对于列表则不行。它返回一个500(内部服务器错误)
。这是我的代码:
ASP.NET MVC Web API
public class PostTraceController : ApiController
{
public HttpResponseMessage Post(List<WebTrace> list)
{
try
{
// Some code
return Request.CreateResponse(HttpStatusCode.Created);
}
catch (Exception ex)
{
HttpContext.Current.Trace.Write("exception", ex.Message);
return Request.CreateErrorResponse(HttpStatusCode.ServiceUnavailable, ex);
}
}
public HttpResponseMessage Post(WebTrace item)
{
try
{
// Some code
return Request.CreateResponse(HttpStatusCode.Created);
}
catch (Exception ex)
{
HttpContext.Current.Trace.Write("exception", ex.Message);
return Request.CreateErrorResponse(HttpStatusCode.ServiceUnavailable, ex);
}
}
}
Win forms application
public class BaseSender
{
public BaseSender()
{
Client = new HttpClient
{
BaseAddress = new Uri(@"http://localhost/mywebsite/")
};
Client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
}
public string UserCode { get; set; }
protected readonly HttpClient Client;
public HttpResponseMessage PostAsJsonAsync(string requestUri, object value)
{
var response = Client.PostAsJsonAsync(requestUri, value).Result;
response.EnsureSuccessStatusCode();
return response;
}
}
public class WebTraceSender : BaseSender
{
private const string requestUri = "api/posttrace";
public bool Post(List<ArchiveCptTrace> list)
{
try
{
var listWebTrace = new List<WebTrace>();
foreach (var item in list)
{
listWebTrace.Add(new WebTrace
{
DateStart = item.DatePreparation,
DateEnd = item.DateCloture,
UserStart = item.UserPreparation.UserName,
UserEnd = item.UserCloture.UserName,
AmountStart = item.MontantPreparation,
AmountEnd = item.MontantCloture,
TheoricAmountEnd = item.MontantTheorique,
Difference = item.Ecart,
UserCode = UserCode
});
}
var responce = PostAsJsonAsync(requestUri, listWebTrace);
return responce.IsSuccessStatusCode;
}
catch (Exception e)
{
// TODO : Trace the exception
return false;
}
}
}
编辑:
我已经找出了错误的场景,即我的api控制器中有两种方法,尽管它们具有不同的签名。如果我注释掉一个方法,那么发布就可以正常工作(项目或列表)。有什么想法吗?
