Hello,
In this particular scenario, I would suggest going through Zack's recommendation first to see if that answers your questions.
If you have already tried adding a NetworkCredential with username/password and still the server denies access (does not challenge the client for username/password). I would also suggest trying out the following code if your server implements a HTTP Basic authentication.
private void EagerlyAddNetworkCredentials(object sender, HttpRequestMessage e)
{
var anyCred = Esri.ArcGISRuntime.Security.AuthenticationManager.Current.FindCredential(e.RequestUri, AuthenticationType.NetworkCredential);
if (anyCred is ArcGISNetworkCredential runtimeNetCred)
{
// If a NetworkCredential is found for this request, but we are still waiting to be challenged...
if (!e.Headers.Contains("Authorization"))
{
// Generate an HTTP Basic Authorization header per RFC 2617
var netCred = runtimeNetCred.Credentials.GetCredential(e.RequestUri, "Basic");
var rawCredentialBytes = Encoding.GetEncoding("ISO-8859-1").GetBytes($"{netCred.UserName}:{netCred.Password}");
// Add it to the request
e.Headers.Add("Authorization", $"Basic {Convert.ToBase64String(rawCredentialBytes)}");
}
}
}
//Loads the service
private async void WFSNetworkCred()
{
ArcGISHttpClientHandler.HttpRequestBegin += EagerlyAddNetworkCredentials;
MyView.Map = new Map(Basemap.CreateImagery());
var am = Esri.ArcGISRuntime.Security.AuthenticationManager.Current;
am.AddCredential(new ArcGISNetworkCredential
{
ServiceUri = new Uri("Insert_Service_URL_Here"),
Credentials = new NetworkCredential("username", "password"),
});
var wfs = "Insert_Service_URL_Here";
var wfsService = new WfsService(new Uri(wfs));
await wfsService.LoadAsync();
}
I protected a local GeoServer service with a username and password. Some OGC services do not challenge the clients to log in. The service needs an `Authentication` header present in the request (for ex. Basic authentication header). This scenario forces the clients to `eagerly` send their login info with the request itself and not wait for the challenge to come back.
This is currently not supported in the Runtime SDK. However, a possible workaround could be to tap into the ArcGISHttpClientHandler.HttpRequestBegin Event, forcing it to add our NetworkCredentials with the outgoing requests (like in the code above).
I hope this works for you. Let me know if you face any problems.
