【问题描述】：
我使用以下模板创建了 WCF 服务：
http://visualstudiogallery.msdn.microsoft.com/fbc7e5c1-a0d2-41bd-9d7b-e54c845394cd
这个服务有这样一个方法：
[ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
public class RecordingCompleted
{
[WebInvoke(UriTemplate = "", Method = "POST")]
public string ProcessCall(string JsonData)
{
}
}
我已经在 IIS 上托管了这个服务，方法的 url 是：
http://[本地] 主机/Notifications/RecordingCompleted/
当我在地址栏中输入这个地址时，我得到：
Method not allowed. Please see the service help page for constructing valid requests to the service.
我正在尝试使用以下代码使用此 Web 服务：
string serviceBaseUrl = "http://[local] host/Notifications/RecordingCompleted/";
string resourceUrl = "";
string method = "POST";
//string jsonText = "}";
UseHttpWebApproach(serviceBaseUrl, resourceUrl, method, jsonText);
方法如下：
private string UseHttpWebApproach(string serviceUrl, string resourceUrl, string method, string requestBody)
{
string responseMessage = null;
var request = WebRequest.Create(string.Concat(serviceUrl, resourceUrl)) as HttpWebRequest;
if (request != null)
{
request.ContentType = "application/json";
request.Method = method;
}
//var objContent = HttpContentExtensions.CreateDataContract(requestBody);
if (method == "POST" && requestBody != null)
{
byte[] requestBodyBytes = ToByteArrayUsingJsonContractSer(requestBody);
request.ContentLength = requestBodyBytes.Length;
using (Stream postStream = request.GetRequestStream())
postStream.Write(requestBodyBytes, 0, requestBodyBytes.Length);
}
if (request != null)
{
var response = request.GetResponse() as HttpWebResponse;
if (response.StatusCode == HttpStatusCode.OK)
{
Stream responseStream = response.GetResponseStream();
if (responseStream != null)
{
var reader = new StreamReader(responseStream);
responseMessage = reader.ReadToEnd();
}
}
else
{
responseMessage = response.StatusDescription;
}
}
return responseMessage;
}
private static byte[] ToByteArrayUsingJsonContractSer(string requestBody)
{
byte[] bytes = null;
var serializer1 = new DataContractJsonSerializer(typeof(string));
var ms1 = new MemoryStream();
serializer1.WriteObject(ms1, requestBody);
ms1.Position = 0;
var reader = new StreamReader(ms1);
bytes = ms1.ToArray();
return bytes;
}
我正在尝试调试服务方法，但我不知道该怎么做。请告诉我为什么我在输入时出现错误 地址栏中的 http://[local] host/Notifications/RecordingCompleted/。以及如何调试托管在本地主机上的服务？
问候， 阿西夫·哈米德
【问题讨论】：

你为什么用
http://[local] host/而不是http://localhost/？尝试修复你的 serviceBaseUrl。 -
那只是因为在 Stackoverflow 中我们无法输入有问题的 locahost。
