Самый простой способ сделать это - определить операции для обработки случаев "Not Found" - с помощью UriTemplate '*' (он будет совпадать, если другие шаблоны не соответствуют входящему запросу). Код ниже показывает пример этого.
public class Post_0424d917_89cd_43c8_be70_5d4c6934b48c
{
[ServiceContract]
public interface ITest
{
[WebGet(UriTemplate = "/Echo?text={text}")]
string EchoGet(string text);
[WebInvoke(UriTemplate = "/Echo")]
string EchoPost(string text);
[WebGet(UriTemplate = "*")]
Stream ErrorForGet();
[WebInvoke(UriTemplate = "*")]
Stream ErrorForPost();
}
public class Service : ITest
{
public string EchoGet(string text) { return text; }
public string EchoPost(string text) { return text; }
public Stream ErrorForPost() { return this.ErrorForGet(); }
public Stream ErrorForGet()
{
WebOperationContext.Current.OutgoingResponse.StatusCode = HttpStatusCode.NotFound;
WebOperationContext.Current.OutgoingResponse.ContentType = "text/html";
string result = @"<html>
<head>
<title>Resource not found</title>
</head>
<body>
<h1>This resource cannot be found</h1>
</body>
</html>";
return new MemoryStream(Encoding.UTF8.GetBytes(result));
}
}
static void SendRequest(string uri, string method, string contentType, string body)
{
HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(uri);
req.Method = method;
if (!String.IsNullOrEmpty(contentType))
{
req.ContentType = contentType;
}
if (body != null)
{
byte[] bodyBytes = Encoding.UTF8.GetBytes(body);
req.GetRequestStream().Write(bodyBytes, 0, bodyBytes.Length);
req.GetRequestStream().Close();
}
HttpWebResponse resp;
try
{
resp = (HttpWebResponse)req.GetResponse();
}
catch (WebException e)
{
resp = (HttpWebResponse)e.Response;
}
Console.WriteLine("HTTP/{0} {1} {2}", resp.ProtocolVersion, (int)resp.StatusCode, resp.StatusDescription);
foreach (string headerName in resp.Headers.AllKeys)
{
Console.WriteLine("{0}: {1}", headerName, resp.Headers[headerName]);
}
Console.WriteLine();
Console.WriteLine(new StreamReader(resp.GetResponseStream()).ReadToEnd());
Console.WriteLine();
Console.WriteLine(" *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* ");
Console.WriteLine();
}
public static void Test()
{
string baseAddress = "http://" + Environment.MachineName + ":8000/Service";
ServiceHost host = new ServiceHost(typeof(Service), new Uri(baseAddress));
host.AddServiceEndpoint(typeof(ITest), new WebHttpBinding(), "").Behaviors.Add(new WebHttpBehavior());

SendRequest(baseAddress + "/Echo", "POST", "application/json", "\"world\"");
