Hi I’m new Aspose, and I’m trying to update an existing application to use OAuth.
We are using version 20.10.0.0, and I have found this documentation:
But if I use the example I get errors on the two lines:
AuthenticationContext authenticationContext = new AuthenticationContext(authority, false);
// it says that the constructor don’t take any arguments
AuthenticationResult authenticationResult = authenticationContext.AcquireToken(resource, clientID, clientAppUri);
// here it says that AuthenticationContext don’t contain a definition for AcuireToken
On the page I linked to, it does not say what versions it covers.
Is the documentation I linked to, only for the newest version?
If yes, does documentation for older versions exists, or do we need to update to newest version?
@barnonline,
Welcome to our community!
To my regret, that documentation article is out of date. Thank you for your notes. I logged the issue in our tracking system with ID EMAILNET-40095 for updating the article.
I hope the next code snippet will help you with actual authentications:
// https://developer.microsoft.com/en-us/graph/blogs/upcoming-changes-to-exchange-web-services-ews-api-for-office-365/
OAuthTestUser oAuthUser = (OAuthTestUser)user;
string[] scopeAr = new string[]
{
// O365 ----------------------
// Exchange Web Services will not receive feature updates
// Basic Authentication for EWS will be decommissioned
// https://developer.microsoft.com/en-us/graph/blogs/upcoming-changes-to-exchange-web-services-ews-api-for-office-365/
// https://docs.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-authenticate-an-ews-application-by-using-oauth#add-code-to-get-an-authentication-token
"https://outlook.office.com/EWS.AccessAsUser.All",
};
ITokenProvider tokenProvider = new AzureROPCTokenProvider(
oAuthUser.Tenant,
oAuthUser.ClientId,
oAuthUser.ClientSecret,
oAuthUser.EMail,
oAuthUser.Password,
scopeAr);
NetworkCredential credentials = new OAuthNetworkCredential(tokenProvider);
IEWSClient client = EWSClient.GetEWSClient(server.EWSUrl, credentials);
I tried your code snippet, but now it does not recognize “AzureROPCTokenProvider”
I
I then googled “AzureROPCTokenProvider” and there was only a single link to your support forum.
I then created the sample of simple implementation of ITokenProvider mentioned in the thread, but then the AzureTokenResponse was an unknown type, and finally I found this on stack overflow.
In the end I decided to go with microsofts Identity.Client
// Using Microsoft.Identity.Client 4.22.0
var cca = ConfidentialClientApplicationBuilder
.Create("appID")
.WithClientSecret("clientsecret")
.WithTenantId("tenantID")
.Build();
// The permission scope required for EWS access
var ewsScopes = new string[] { "https://outlook.office365.com/.default" };
//Make the token request
var authResult = await cca.AcquireTokenForClient(ewsScopes).ExecuteAsync();
@barnonline,
Thank you for your investigation. Yes, AzureROPCTokenProvider class is our implementation of ITokenProvider interface for tests. My code snippet demonstrates a custom authentication without details. I am glad to see that you found the solution with Identity.Client.
