Web API プロジェクトを作成していますが、xml を使用しようとするとメソッドの 1 つが停止することに気付きました。これは私の好みの方法であり、正常に動作するため、通常はテスト時にjsonを使用します。
public HttpResponseMessage GetStoreNames(StoreDm vm)
{
if (ModelState.IsValid)
{
var result = storeService.AutoCompleteStore(vm.Latitude, vm.Longitude, vm.Name);
return Request.CreateResponse <ResponseResult<AutoCompleteSearchDto>>(result.Status.Code, result);
}
var responseResult = new ResponseResultWrapper();
responseResult.Status.Code = HttpStatusCode.BadRequest;
responseResult.Status.Message = GenericErrors.InvalidRequest;
responseResult.ModelStateToResponseResult(ModelState);
return Request.CreateResponse<ResponseResult>(responseResult.Status.Code, responseResult);
}
[DataContract(Name = "MyRoot")]
public class ResponseResultWrapper : ResponseResult
{
public void ModelStateToResponseResult(ModelStateDictionary modelState)
{
foreach (var kvp in modelState)
{
foreach (var error in kvp.Value.Errors)
{
string key = kvp.Key;
string msg = error.ErrorMessage;
if (String.IsNullOrEmpty(msg))
{
msg = error.Exception.Message;
}
base.AddError(key, msg);
}
}
}
}
[DataContract(Name = "MyRoot")]
public class ResponseResult
{
public ResponseResult()
{
Errors = new Dictionary<string, string>();
Status = new ResponseBase();
}
public void AddError(string key, string errorMessage)
{
if (!Errors.ContainsKey(key))
{
Errors.Add(key, errorMessage);
}
}
public bool IsValid()
{
if (Errors.Count > 0)
{
return false;
}
return true;
}
[DataMember]
public Dictionary<string, string> Errors { get; private set; }
[DataMember]
public ResponseBase Status { get; set; }
}
[DataContract(Name = "MyRoot")]
public class ResponseResult<T> : ResponseResult
{
[DataMember]
public T Response { get; set; }
}
このエラーが発生します

「Youssef Moussaoui」の回答の最初の部分を試した後、このエラーが発生しました。
There was an error deserializing the object of type StoreDm. The data at the root level is invalid. Line 1, position 1.
「ResponseResultWrapper」と「ResponseResult」は 2 つの異なるライブラリにあるため、彼の 2 番目の部分を実際に行うことはできません。
