Authorization - WSDL File, Proxy class in C#

Question

Authorization - WSDL File, Proxy class in C#

Markus Freitag 3,756

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....???

Hi there,

Basic authentication is supported by specifying a policy in the WSDL. A basic authentication policy can be added to the WSDL either manually or by using the WS-Policy Attachment window accessed from CASA and provided through Tango (WSIT). A basic authentication policy is specified at the root level of the WSDL and a reference to the policy is made in the WSDL Port type section, binding the policy to the endpoint.

Thanks for the answer.

Yes, Can you make a sample for manually? Or both?

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.

I found this.

dMES.RequestEncoding =

Can I set it to

     request.Accept = "text/xml";  
     request.ContentType = "text/xml";  
     request.Headers.Add("Content-Encoding", "utf-8");

I found nothing.

My best guess is the SOAP service expects SOAP version 1.2 Try using svcutil.exe rather than wsdl.exe to create the proxy.

Again, the service owners know how their service works. Either read the the support docs or contact the service owners. You also might consider taking classes on SOAP or setting aside time to learn the protocol.

OK, but it a way to set this request.ContentType = "text/xml";

Problem: No support from service owner. Reason: No experience with C#

The standard soap fault (screenshot) indicates the client request is bad. If you are using the actual code generated by the wsdl.exe and are not calling a mock service then I suspect the service expects the soap action defined in the soap message not the HTTP header. This is just a guess as I do not have the wsdl, service documentation, your source code, or steps to reproduce the problem.

Did you at least try my suggestion and create the proxy using svcutil.exe???

Problem: No support from service owner. Reason: No experience with C#

This is not a C# support question. Looking at the request screenshot I'm guessing you are calling an oracle web service. Perhaps Oracle support is a better location to get help.

Hello,

use now

svcutil AuthenNEW.wsdl /language:C#

system-servicemodel-missing

Some DLLs missing, I added it.
Not work, no Url inside the proxy class. Is my call wrong?

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);
}

Hello @AgaveJoe ,

Thanks!

private void btnGet_Order_Queue_Click(object sender, EventArgs e)  
{  
	using (PDC_WS_LMEService dMES = new PDC_WS_LMEService()  
	{  
		Credentials = new NetworkCredential("userXXX", "passWordXXXX"),  
		PreAuthenticate = true,  
		Url = "http://AXXXA724:8080/orawsv/PDS/PSLME"  
	})   
	{  
		try  
		{  
			ORD_REQType requestInput = new ORD_REQType();  
			requestInput.ORD_REQ = new ORD_REQTypeLREQ();

I think it is better, i got another error.

  The request content type found by the client is 'text/html; charset=iso-8859-1', was expected 'text/xml'.  
    Error message  
    --  
    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

What can be the cause, how can I change this?
From customer! With SoapUI
Is Basic

Can it be the WSDL file? Is wrong, false type. Can I create this myself? Maybe with SoapUi

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.

ok, but maybe there is a way to set it inside my code. Creditional?

    WebRequest request = WebRequest.Create(url);
        request.Method = WebRequestMethods.Http.Get;
        NetworkCredential networkCredential = new NetworkCredential(logon, password); // logon in format "domain\username"
        CredentialCache myCredentialCache = new CredentialCache {{new Uri(url), "Basic", networkCredential}};
        request.PreAuthenticate = true;
        request.Credentials = myCredentialCache;

Like this.
I have a WSDL file, call WSDL.EXE to create a proxy class --> IO
Now customer told me, he need a autorisation. I never made it, now idea.
Is it possible via wrapper class or it is a todo, when I create the proxy class?
How I can set, user, password and the authorisation id.

I'm a little confused. The code you're shared is NOT taking advance of the proxy class. Why did you create a service proxy if you are not planning to use the proxy?

Secondly, network credentials and basic authentication illustrated above are two different types of credentials unrelated to the proxy class request/response types. The service owners must supply these credentials or provide the steps to create an account on their system. For the last time, how does the security work! Do you have credentials???

Hello,

I use WSDL.EXE to create a wrapper, proxy class. Works.

 using (LMEService dMES = new LMEService())
            {
                try
                {

                    dMES.Url = "http://AA3334:8080/orav/WS/WS_LME";

                    dMES.Credentials

I have only Credentials.

string credentials1 = String.Format("{0}:{1}", "usernameTEST", "userPassTest");
                    byte[] bytes = Encoding.ASCII.GetBytes(credentials1);
                    string base64 = Convert.ToBase64String(bytes);
                    string authorization = String.Concat("Basic ", base64);
                   // dMES.Headers.Add("Authorization", authorization);

I have here no Headers, how can I solve it?

Thanks for help in advance. My code.

  CredentialCache cc = new CredentialCache();
                    cc.Add(
                        new Uri(dMES.Url),
                        "Basic",
                        new NetworkCredential("userNameTest", "userPasswordTest"));
                    dMES.Credentials = cc;

                    dMES.PreAuthenticate = true;
