Post SOAP Envelope to WCF service

Question

Hi,

I have the following SOAP message that i want to post it to my WCF Service and get response.

"<s:Envelope xmlns:a=\"http://www.w3.org/2005/08/addressing\" xmlns:s=\"http://www.w3.org/2003/05/soap-envelope\"&gt;\r\n  <s:Header>\r\n    <a:Action s:mustUnderstand=\"1\">http://schemas.devleap.com/OrderService/IOrderService/InsertOrder&lt;/a:Action&gt;\r\n    <a:MessageID>urn:uuid:4cb619b7-365b-4108-880f-b302029d03c2</a:MessageID>\r\n    <a:ReplyTo>\r\n      <a:Address>http://www.w3.org/2005/08/addressing/anonymous&lt;/a:Address&gt;\r\n    </a:ReplyTo>\r\n  </s:Header>\r\n  <s:Body>\r\n    <InsertOrder xmlns=\"http://schemas.devleap.com/OrderService\"&gt;\r\n      <order xmlns:d4p1=\"http://schemas.devleap.com/OrderService/Order\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\"&gt;\r\n        <d4p1:IdCustomer>2</d4p1:IdCustomer>\r\n        <d4p1:IdOrder>46</d4p1:IdOrder>\r\n        <d4p1:OrderItems xmlns:d5p1=\"http://schemas.devleap.com/OrderService/OrderItems\" xmlns:d5p2=\"http://schemas.devleap.com/OrderService/OrderItem\"&gt;\r\n          <d5p1:OrderItem>\r\n            <d5p2:IdProduct>P01</d5p2:IdProduct>\r\n            <d5p2:Quantity>5</d5p2:Quantity>\r\n            <d5p2:EuroPrice>20</d5p2:EuroPrice>\r\n          </d5p1:OrderItem>\r\n          <d5p1:OrderItem>\r\n            <d5p2:IdProduct>P01</d5p2:IdProduct>\r\n            <d5p2:Quantity>5</d5p2:Quantity>\r\n            <d5p2:EuroPrice>20</d5p2:EuroPrice>\r\n          </d5p1:OrderItem>\r\n        </d4p1:OrderItems>\r\n      </order>\r\n    </InsertOrder>\r\n  </s:Body>\r\n</s:Envelope>"

How can i post this SOAP to the WCF service? I tried this but i get "The remote server returned an error: (500) Internal Server Error." exception.

        using (var client = new WebClient())
        {

            client.Headers.Add("Content-Type", "application/soap+xml; charset=utf-8");


            var response = client.UploadString("http://localhost:8000/OrderService", data);

        }

If i remove the header from Envelope and add:

client.Headers.Add("Content-Type", "application/soap+xml; charset=utf-8");
client.Headers.Add("SOAPAction", "\"http://schemas.devleap.com/OrderService/IOrderService/InsertOrder\"");

i get the same error.

If i put

client.Headers.Add("Content-Type", "text/xml; charset=utf-8");

i get exception that server expects "application/soap+xml; charset=utf-8".

If someone knows how to call it right please help.

Thank you, Adrya

Answer 1

1. Create a SOAP client side proxy for the WCF Service by using Add Service Reference in Visual Studio (by specifying the service's URL)

2. Instantiate that client proxy class

3. Call the appropriate method on the client proxy to send the SOAP message to your serviec

After more digging i managed to post the SOAP to the service. Here is code:

        WebClient myWebClient = new WebClient();
        myWebClient.Headers.Add("Content-Type", "application/soap+xml; charset=utf-8");
        byte[] byteArray = Encoding.ASCII.GetBytes(postData);
        byte[] responseArray = myWebClient.UploadData("http://localhost:8000/OrderService", "POST", byteArray);
        Console.WriteLine("\nResponse received was {0}", Encoding.ASCII.GetString(responseArray));
        Console.ReadKey();
