Authorization - WSDL File, Proxy class in C#

Question

Hello,

I have received a WSDL file from a customer. With this I have created a proxy class via WSDL. --> IO
The server must be connected via Authorization.
I don't see anything there. How can I make the connection via Authorization?
The proxy class is quite complex. I need only 2 requests.

Is there any way I can best create the request. There is no support from the customer.

The alternative would be to create it myself via XDocument, which I am not in favor of.

 private void btnOrderData_Click(object sender, EventArgs e)
        {
            using (PDXCSMEService danS = new PDXCSMEService())
            {
                //danS .Url = "";

//  danS.Auto....???

Not work, no Url inside the proxy class. Is my call wrong?

I'm guessing you did not thoroughly read the svcutil.exe reference documentation which clearly indicates the svcutil.exe creates a output.config file. The config file contains the URL as well as other configurations. Either rename output.config to app.config and place the file in the application root or copy the appropriate nodes to you app.config file.

Keep in mind, I'm just guessing what's wrong as I do not have the wsdl, service documentation, and you've provide very little code. Still the service owners are your best option. Otherwise, maybe hire someone that can help you.

Example configuration that uses HTTP. Change to Transport security for HTTPS.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="WebServiceSoap">
     <security mode="TransportCredentialOnly">
     <transport clientCredentialType="Basic" />
     </security>
     </binding>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost/WebService/WebService.asmx"
                binding="basicHttpBinding" bindingConfiguration="WebServiceSoap"
                contract="WebServiceSoap" name="WebServiceSoap" />
        </client>
    </system.serviceModel>
</configuration>

Implementation

static void Main(string[] args)
{
    WebServiceSoapClient client = new WebServiceSoapClient("WebServiceSoap");

    client.ClientCredentials.UserName.UserName = "username";
    client.ClientCredentials.UserName.Password = "password!";

    string resposne = client.HelloWorld();
    Console.WriteLine(resposne);
}

If you use wsdl.exe to generate the proxy class the class has a credentials property you can set to a network credentials

Answer 3

There are several ways to secure a SOAP service. The members of this forum have no idea how the SOAP security works. You have no choice but to contact the service owners for support.

Answer 4

You still have not told us how the security works! If the service uses basic authentication and you have credentials then the pattern below will work.

static void Main(string[] args)
{
    RemoteService.WebService client = new RemoteService.WebService()
    {
        Credentials = new NetworkCredential("username", "password"),
        PreAuthenticate = true,
        Url = "http://localhost/WebService/WebService.asmx"
    };

    string resposne = client.HelloWorld();
    Console.WriteLine(resposne);
}

The client, which I assume is SoapUI, expects an XML response (SOAP) but instead received an HTML response. Commonly, the HTML response it is an error message from the server. Open the HTML in a browser and/or read the contents of the message.
