SOAP web request RRS feed

  • Question

  • User580518845 posted

    I am using this link to create the soap envelop.

    But when I reach request.GetResponse(), I get error."The remote server returned an error: (500) Internal Server Error."

    I think the error is because of the
    webRequest.Headers.Add(@"SOAP:Action"), do I need to add any name space etc to the soap action?

    public HttpWebRequest CreateWebRequest()
    string soapAction =@"SOAP:Action"; // is this correct?
    HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(@"https://myServiceURL/services");
    webRequest.ContentType = "text/xml;charset=\"utf-8\"";
    //webRequest.ContentType = "text/xml;charset=\"utf-8\";action=\""+ soapAction + "\"";
    webRequest.Accept = "text/xml";
    webRequest.Method = "POST";
    return webRequest;

    using this link to create the soap envelop.

    Example shown in the above referred article is accessing SOAP based Web Service.


    HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(@"https://myServiceURL/services")

    You are accessing a RESTFul service (which is evident from the URI provided).

    Refer Consuming Restful Service section at http://www.codeproject.com/Articles/255684/Create-and-Consume-RESTFul-Service-in-NET-Framewor


    Note that HTTP POST verb is used to create new resource(i.e., new data record in database) in RESTFul service. 

    string soapAction =@"SOAP:Action"; // is this correct? 
    No. This is not requried. Refer amended source below.
    public HttpWebRequest CreateWebRequest()
    HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(@"https://myServiceURL/services");
    webRequest.Method = "POST";
    WebRequest.ContentType = @"application/xml; charset=utf-8";
    return webRequest;
    Note:- when the service is protected(security), client (above source) needs to provide valid credentials.
    It is expected that above method is called in another operation to create a request to the service. then process the response received from the service.
    static void Main(string[] args)
       //calling the above operation that creates service request 
      //POST data to the service using 
      //receive the service response || similar to the one below.
      HttpWebResponse resp = req.GetResponse() as HttpWebResponse;
            Console.WriteLine(string.Format("Status Code: {0}, Status Description: {1}", resp.StatusCode, resp.StatusDescription));

    Thank you for the reply.

    I try adding  these two lines

    webRequest.Method = "POST"; 
    WebRequest.ContentType = @"application/xml; charset=utf-8";
    still I get the same error.

    in the code  below, Yes I use the https://     

    I added the userid and password in the xml file of this line

    soapEnvelopeXml.LoadXml(@"<soap:Envelope xmlns:soap...

    and do you see anything wrong in the link http://www.roelvanlisdonk.nl/?p=1893?

    The only difference I can see is, they use 

     soapEnvelopeXml.LoadXml(@"<?xml version=""1.0"" encoding=""utf-8""?> <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema""> <soap:Body> <HelloWorld3 xmlns=""http://tempuri.org/"">

    and my xmlfile does not have this header section below

    <?xml version=""1.0"" encoding=""utf-8""?>

    webservice gave response back for the request XML I created when I tried with "SOAPUI" program.
    So I guess something is wrong with my header file to create the soapenvelope.

    I just tried adding the  <?xml version=""1.0"" encoding=""utf-8""?>  to the 

    soapEnvelopeXml.LoadXml, still I get the same 500 error.


    my wsdl have a section like this blow. So I thought I need a the soapaction in the request header with the URI

    soapAction="http://xmldefs.bcd.sa.shs/Common/V1/FindsearchInventory" />
    b) Here is the complete code.

    Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    'Reference: http://www.roelvanlisdonk.nl/?p=1893
    Dim request As HttpWebRequest = CreateWebRequest()
    Dim soapEnvelopeXml As New XmlDocument()
    'soapEnvelopeXml.LoadXml("<soapenv:Envelope xmlns:soapenv=""http://schemas.xmlsoap.org/soap/envelope/"" ..../soapenv:Envelope>")
    soapEnvelopeXml.LoadXml("<?xml version=""1.0"" encoding=""utf-8""?><soapenv:Envelope xmlns:soapenv=""http://schemas.xmlsoap.org/soap/envelope/"" ......<wsse:UsernameToken><wsse:Username>XXXXXX</wsse:Username> <wsse:Password>YYYYYY</wsse:Password>.......</soapenv:Body></soapenv:Envelope>")
    Using stream As Stream = request.GetRequestStream()
    End Using
    Using response As WebResponse = request.GetResponse()
    Using rd As New StreamReader(response.GetResponseStream())
    Dim soapResult As String = rd.ReadToEnd()
    End Using
    End Using
    End Sub
    Public Function CreateWebRequest() As HttpWebRequest
    Dim soapAction As String = "http://xmldefs.bcd.sa.shs/Common/V1/FindsearchInventory"
    Dim webRequest2 As HttpWebRequest = DirectCast(WebRequest.Create("https://Mywebervices"), HttpWebRequest)
    ' webRequest2.ContentType = "application/soap+xml;charset=UTF-8;action=""" + soapAction + """"
    webRequest2.ContentType = "application/xml;charset=UTF-8;"
    webRequest2.Method = "POST"
    'webRequest2.Headers.Add("Cache-Control: no-Cache")
    'webRequest2.Credentials = New NetworkCredential("xxxx", "yyyyy") 'userid and password
    Return webRequest2
    End Function

    Please tell me what is wrong with the code.
