Facing issues when I try to add a webservice in visual studio 2010

Question

I need to consume a web service. that webservice requires user authentication. When I try to add a reference to the web service I'm getting a error saying

The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Basic realm="AXIS"'. The remote server returned an error: (401) Unauthorized. If the service is defined in the current solution, try building the solution and adding the service reference again.

Is there any way to get out of this error?

Answer 1

You need to provide the Credentials from your Code and also configure the clientCredentialType Type and realm from you app.config file.

follow below steps:

Step1 :
add following set of tags in your app.config file.

<security mode="TransportCredentialOnly">
<transport clientCredentialType="Basic" proxyCredentialType="None"
 realm="AXIS" />

Step 2:

from your code before accessing the API you need to provide credentials(UserName and Password).

//you must be having below two lines of code already in your code. Assuming your WebServiceCLient as ProjectWebServiceClient

ProjectWebServiceClient client;
client = new ProjectWebServiceClient();

//Add following two lines of code in your source code:

 client.ClientCredentials.UserName.UserName = "yourusername";
 client.ClientCredentials.UserName.Password = "yourpassword";
