是的,通过AppAuth库可以实现使用用户名和密码登录OpenID-Connect服务。下面是一个使用AppAuth库实现此功能的示例代码:
import net.openid.appauth.AuthorizationException;
import net.openid.appauth.AuthorizationRequest;
import net.openid.appauth.AuthorizationResponse;
import net.openid.appauth.AuthorizationService;
import net.openid.appauth.TokenRequest;
import net.openid.appauth.TokenResponse;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
public class OpenIDConnectLogin {
private static final String CLIENT_ID = "your-client-id";
private static final String REDIRECT_URI = "your-redirect-uri";
private static final String AUTH_ENDPOINT = "openid-connect-auth-endpoint";
private static final String TOKEN_ENDPOINT = "openid-connect-token-endpoint";
private final ExecutorService mExecutor = Executors.newSingleThreadExecutor();
private AuthorizationService mAuthService;
public void loginWithUsernameAndPassword(String username, String password) {
mAuthService = new AuthorizationService(context);
AuthorizationRequest authRequest = new AuthorizationRequest.Builder(
authService,
CLIENT_ID,
AuthorizationRequest.RESPONSE_TYPE_CODE,
REDIRECT_URI
)
.setScope("openid")
.setLoginHint(username)
.build();
authService.performAuthorizationRequest(
authRequest,
PendingIntent.getActivity(context, 0, new Intent(), 0)
);
}
public void handleAuthorizationResponse(Intent intent) {
AuthorizationResponse response = AuthorizationResponse.fromIntent(intent);
AuthorizationException error = AuthorizationException.fromIntent(intent);
if (response != null) {
TokenRequest tokenRequest = response.createTokenExchangeRequest();
mAuthService.performTokenRequest(
tokenRequest,
new AuthorizationService.TokenResponseCallback() {
@Override
public void onTokenRequestCompleted(
TokenResponse tokenResponse, AuthorizationException exception) {
if (tokenResponse != null) {
String accessToken = tokenResponse.accessToken;
// 使用access token进行后续操作
} else {
// 处理错误情况
}
}
}
);
} else {
// 处理错误情况
}
}
}
在上面的示例中,loginWithUsernameAndPassword方法接受用户名和密码作为参数,并使用AppAuth库创建一个AuthorizationRequest对象。在这个对象中,我们设置了客户端ID、重定向URI、授权端点和令牌端点等必要参数。同时,我们还将用户名设置为登录提示,以便OpenID-Connect服务知道用户要使用用户名和密码进行登录。
然后,我们使用performAuthorizationRequest方法开始授权请求流程,并将结果传递给handleAuthorizationResponse方法进行处理。在handleAuthorizationResponse方法中,我们从响应中获取令牌请求,并使用performTokenRequest方法向令牌端点发送令牌请求,并获取访问令牌。最后,我们可以使用获得的访问令牌进行后续操作。
请注意,这只是一个基本示例,真实的应用可能需要更多的错误处理和安全性控制。
