First thing is to know the exact URL for your REST Service. Since you have specified http://localhost:2517/Service1/Create
now just try to open the same URL from IE and you should get method not allowed as your Create
Method is defined for WebInvoke and IE does a WebGet.
Now make sure that you have the SampleItem in your client app defined in the same namespace on your server or make sure that the xml string you are building has the appropriate namespace for the service to identify that the xml string of sample object can be deserialized back to the object on server.
I have the SampleItem defined on my server as shown below:
namespace SampleApp
{
public class SampleItem
{
public int Id { get; set; }
public string StringValue { get; set; }
}
}
The xml string corresponding to my SampleItem is as below:
<SampleItem xmlns="http://schemas.datacontract.org/2004/07/SampleApp" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><Id>6</Id><StringValue>from client testing</StringValue></SampleItem>
Now i use the below method to perform a POST to the REST service :
private string UseHttpWebApproach<T>(string serviceUrl, string resourceUrl, string method, T requestBody)
{
string responseMessage = null;
var request = WebRequest.Create(string.Concat(serviceUrl, resourceUrl)) as HttpWebRequest;
if (request != null)
{
request.ContentType = "application/xml";
request.Method = method;
}
//var objContent = HttpContentExtensions.CreateDataContract(requestBody);
if(method == "POST" && requestBody != null)
{
byte[] requestBodyBytes = ToByteArrayUsingDataContractSer(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[] ToByteArrayUsingDataContractSer<T>(T requestBody)
{
byte[] bytes = null;
var serializer1 = new DataContractSerializer(typeof(T));
var ms1 = new MemoryStream();
serializer1.WriteObject(ms1, requestBody);
ms1.Position = 0;
var reader = new StreamReader(ms1);
bytes = ms1.ToArray();
return bytes;
}
Now i call the above method as shown:
SampleItem objSample = new SampleItem();
objSample.Id = 7;
objSample.StringValue = "from client testing";
string serviceBaseUrl = "http://localhost:2517/Service1";
string resourceUrl = "/Create";
string method="POST";
UseHttpWebApproach<SampleItem>(serviceBaseUrl, resourceUrl, method, objSample);
I have the SampleItem object defined in the client side as well. If you want to build the xml string on the client and pass then you can use the below method:
private string UseHttpWebApproach(string serviceUrl, string resourceUrl, string method, string xmlRequestBody)
{
string responseMessage = null;
var request = WebRequest.Create(string.Concat(serviceUrl, resourceUrl)) as HttpWebRequest;
if (request != null)
{
request.ContentType = "application/xml";
request.Method = method;
}
//var objContent = HttpContentExtensions.CreateDataContract(requestBody);
if(method == "POST" && requestBody != null)
{
byte[] requestBodyBytes = ASCIIEncoding.UTF8.GetBytes(xmlRequestBody.ToString());
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;
}
And the call to the above method would be as shown below:
string sample = "<SampleItem xmlns="http://schemas.datacontract.org/2004/07/XmlRestService" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><Id>6</Id><StringValue>from client testing</StringValue></SampleItem>";
string serviceBaseUrl = "http://localhost:2517/Service1";
string resourceUrl = "/Create";
string method="POST";
UseHttpWebApproach<string>(serviceBaseUrl, resourceUrl, method, sample);
NOTE: Just make sure that your URL is correct
