下面是我在代码中所做的:
if (clientKeyStore == null) {
Log.i(LOG_TAG, "Cert/key was not found in keystore - creating new key and certificate.");
new Thread(new Runnable() {
@Override
public void run() {
try {
// Create a new private key and certificate. This call
// creates both on the server and returns them to the
// device.
CreateKeysAndCertificateRequest createKeysAndCertificateRequest =
new CreateKeysAndCertificateRequest();
createKeysAndCertificateRequest.setSetAsActive(true);
final CreateKeysAndCertificateResult createKeysAndCertificateResult;
createKeysAndCertificateResult =
mIotAndroidClient.createKeysAndCertificate(createKeysAndCertificateRequest);
Log.i(LOG_TAG,
"Cert ID: " +
createKeysAndCertificateResult.getCertificateId() +
" created.");
// store in keystore for use in MQTT client
// saved as alias "default" so a new certificate isn't
// generated each run of this application
AWSIotKeystoreHelper.saveCertificateAndPrivateKey(certificateId,
createKeysAndCertificateResult.getCertificatePem(),
createKeysAndCertificateResult.getKeyPair().getPrivateKey(),
keystorePath, keystoreName, keystorePassword);
// load keystore from file into memory to pass on
// connection
clientKeyStore = AWSIotKeystoreHelper.getIotKeystore(certificateId,
keystorePath, keystoreName, keystorePassword);
// Attach a policy to the newly created certificate.
// This flow assumes the policy was already created in
// AWS IoT and we are now just attaching it to the
// certificate.
AttachPrincipalPolicyRequest policyAttachRequest =
new AttachPrincipalPolicyRequest();
policyAttachRequest.setPolicyName(AWS_IOT_POLICY_NAME);
policyAttachRequest.setPrincipal(createKeysAndCertificateResult
.getCertificateArn());
mIotAndroidClient.attachPrincipalPolicy(policyAttachRequest);
runOnUiThread(new Runnable() {
@Override
public void run() {
btnConnect.setEnabled(true);
}
});
} catch (Exception e) {
Log.e(LOG_TAG,
"Exception occurred when generating new private key and certificate.",
e);
}
}
}).start();
}
}
View.OnClickListener connectClick = new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d(LOG_TAG, "clientId = " + clientId);
try {
mqttManager.connect(clientKeyStore, new AWSIotMqttClientStatusCallback() {
@Override
public void onStatusChanged(final AWSIotMqttClientStatus status,
final Throwable throwable) {
Log.d(LOG_TAG, "Status = " + String.valueOf(status));
runOnUiThread(new Runnable() {
@Override
public void run() {
if (status == AWSIotMqttClientStatus.Connecting) {
tvStatus.setText("Connecting...");
} else if (status == AWSIotMqttClientStatus.Connected) {
tvStatus.setText("Connected");
} else if (status == AWSIotMqttClientStatus.Reconnecting) {
if (throwable != null) {
Log.e(LOG_TAG, "Connection error.", throwable);
}
tvStatus.setText("Reconnecting");
} else if (status == AWSIotMqttClientStatus.ConnectionLost) {
if (throwable != null) {
Log.e(LOG_TAG, "Connection error.", throwable);
}
tvStatus.setText("Disconnected");
} else {
tvStatus.setText("Disconnected");
}
}
});
}
});
} catch (final Exception e) {
Log.e(LOG_TAG, "Connection error.", e);
tvStatus.setText("Error! " + e.getMessage());
}
}
};
keystore中的证书没有读取并给我IoException。
您得到的错误是:
com.amazonaws.AmazonServiceException: User: arn:aws:sts::964546574005:assumed-role/Cognito_GTekPool3Unauth_Role/CognitoIdentityCredentials is not authorized to perform:
