QAToolKit.Auth is a .NET Standard 2.1 library, that retrieves the JWT access tokens from different identity providers. This library should only be used for testing software and not in applications to retrieve the token.
Currently it supports next Identity providers and Oauth2 flows:
Keycloak: Library supports:- client credentials flow or
Protection API token (PAT)flow. Additionally you can replace the PAT with user token by exchanging the token. - resource owner password credentials grant
- client credentials flow or
Azure B2C: Library supports:Identity Server 4: Library supports:
Supported .NET frameworks and standards: netstandard2.0, netstandard2.1, net8.0.
Get in touch with me on:
Please note: The token expiration time is read from the tokens and is used to minimize the hits on the token endpoint. Another benefit is faster tests :).
Keycloak support is limited to the client credential or Protection API token (PAT) flow in combination with token exchange. Additionally you can also get the token by using resource owner password credentials grant.
A mocked request below is sent to the Keycloak endpoint, and the PAT token is retrieved:
curl -X POST \
-H "Content-Type: application/x-www-form-urlencoded" \
-d 'grant_type=client_credentials&client_id=${client_id}&client_secret=${client_secret}' \
"http://localhost:8080/auth/realms/${realm_name}/protocol/openid-connect/token"Read more here in the Keycloak documentation.
Now let's retrive a PAT token with QAToolKit Auth library:
var auth = new KeycloakAuthenticator(options =>
{
options.AddClientCredentialFlowParameters(
new Uri("https://my.keycloakserver.com/auth/realms/realmX/protocol/openid-connect/token"),
"my_client",
"client_secret");
});
var token = await auth.GetAccessToken();If you want to replace the PAT token with user token, you can additionally specify a username. A mocked request looks like this:
curl -X POST \
-H "Content-Type: application/x-www-form-urlencoded" \
-d 'grant_type=urn:ietf:params:oauth:grant-type:token-exchange&client_id=${client_id}&client_secret=${client_secret}&subject_token=eyJhbGciOiJI...&requested_subject=myuser@users.com' \
"http://localhost:8080/auth/realms/${realm_name}/protocol/openid-connect/token"As you see it has a different grant_type and additionally 2 more properties in the URL; PAT token (subject_token) and userName for which we want to replace the token (requested_subject).
var auth = new KeycloakAuthenticator(options =>
{
options.AddClientCredentialFlowParameters(
new Uri("https://my.keycloakserver.com/auth/realms/realmX/protocol/openid-connect/token"),
"my_client",
"client_secret");
});
//Get client credentials flow access token
var token = await auth.GetAccessToken();
//Replace client credentials flow token for user access token
var userToken = await auth.ExchangeForUserToken("myuser@email.com");var auth = new KeycloakAuthenticator(options =>
{
options.AddResourceOwnerPasswordCredentialFlowParameters(
new Uri("https://my.keycloakserver.com/auth/realms/realmX/protocol/openid-connect/token"),
"my_client",
"client_secret",
"user",
"pass");
});
var token = await auth.GetAccessToken();Under the hood it's the same code that retrieves the client credentials flow access token, but authenticator is explicit for Identity Server 4. Additionally you can also get the token by using resource owner password.
var auth = new IdentityServer4Authenticator(options =>
{
options.AddClientCredentialFlowParameters(
new Uri("https://<myserver>/token"),
"my_client"
"<client_secret>");
});
var token = await auth.GetAccessToken();var auth = new IdentityServer4Authenticator(options =>
{
options.AddResourceOwnerPasswordCredentialFlowParameters(
new Uri("https://<myserver>/token"),
"my_client"
"<client_secret>",
"user",
"pass");
});
var token = await auth.GetAccessToken();Under the hood it's the same code that retrieves the client credentials flow access token, but authenticator is explicit for Azure B2C. Additionally you can also get the token by using resource owner password credentials flow.
Azure B2C client credentials flow needs a defined scope which is usually https://graph.windows.net/.default.
var auth = new AzureB2CAuthenticator(options =>
{
options.AddClientCredentialFlowParameters(
new Uri("https://login.microsoftonline.com/<tenantID>/oauth2/v2.0/token"),
"<clientId>"
"<clientSecret>"
new string[] { "https://graph.windows.net/.default" });
});
var token = await auth.GetAccessToken();var auth = new AzureB2CAuthenticator(options =>
{
options.AddResourceOwnerPasswordCredentialFlowParameters(
new Uri("https://login.microsoftonline.com/<tenantID>/oauth2/v2.0/token"),
"<clientId>"
"<clientSecret>"
new string[] { "https://graph.windows.net/.default" },
"user",
"pass");
});
var token = await auth.GetAccessToken();- This library is an early alpha version
