フェデレーションIDを使用してAWS IoTの認証済みユーザを使用してパブリッシュおよびサブスクライブしようとしていました。私が間違いを続けるまではCognitoCachingCredentialsProvider: Failure to get credentials
資格プロバイダ認可されていない例外AWS Android SDK
私はhereを探しました。しかし、彼らが提供したスニペットはもはやFacebookでは使われていない。この問題を解決するにはどうすればよいですか?
のAndroidコード:
public void IntializeAwsIot() {
clientId = "us-east-1:fcbd66e0-***************";
// Initialize the AWS Cognito credentials provider
credentialsProvider = new CognitoCachingCredentialsProvider(
getApplicationContext(), // context
AWSConfiguration.AMAZON_COGNITO_IDENTITY_POOL_ID,// Identity Pool ID
AWSConfiguration.AMAZON_COGNITO_REGION // Region
);
Region region = Region.getRegion(AWSConfiguration.AMAZON_COGNITO_REGION);
// MQTT Client
mqttManager = new AWSIotMqttManager(clientId, CUSTOMER_SPECIFIC_ENDPOINT);
// The following block uses IAM user credentials for authentication with AWS IoT.
//awsCredentials = new BasicAWSCredentials("ACCESS_KEY_CHANGE_ME", "SECRET_KEY_CHANGE_ME");
//btnConnect.setEnabled(true);
// The following block uses a Cognito credentials provider for authentication with AWS IoT.
new Thread(new Runnable() {
@Override
public void run() {
awsCredentials = credentialsProvider.getCredentials();
Connect();
}
}).start();
}
エラー:問題がCognitoキャッシュには資格がありませんでした
