使用しているpython3とUbuntuのバージョンは何ですか？ また、IAMポリシーにどの権限を使用していますか？ 接続に問題があるようです。ポリシーが問題であることを除外するために、 AWSIoTFullAccessから始めることをお勧めします。 後で実際に必要なアクションとリソースのみに制限するようにしてください。

AWSIoTFullAccess：

あなたが言及した追加のコンテンツに関しては、それらの1つはURLにiotがあり、もう1つはiotv2があります。 あなたのために働いているのはどれですか？

応答jmklixをありがとう。
あなたが提案したのは、特にMQTT用ですか？
WebSocketを機能させましたが、.awsクレデンシャルのみを使用しました。これは、私たちのユースケースでは望ましくないと思います。
WebSocketは、mqttが消費する証明書ファイル（xxxx.pem xxx.private.key xxx.public.key）を使用して認証および承認できますか？

はい私はURLiot/ iot2に追いつきました...2つのiotコアバージョンの違いを説明するドキュメントはありますか？
2つのクライアントpythonsdksafaikもあります-1つはpython2.7用で、もう1つはpython 3用ですが、さらに違いはありますか？ それらは、iotおよびiot2コアバージョンと緊密にペアになっていますか？ それらは相互互換性がありますか、それとも下位互換性がありますか？ このためのドキュメントはありますか？

はい、MQTT用です。 いいえ、Webソケットで証明書ファイルを使用することはできません

AWSコンソールですでに作成されているIoT thingsのポリシーを編集できます。 thingを選択し、サブサイドバーでセキュリティを選択します。 そこに証明書が表示され、その証明書を選択する必要があります。 それが開いたら、サブサイドバーでポリシーを選択します。 次に、そのポリシーを選択し、最後にEdit policy documentをクリックして、前にリストしたAWSIoTFullAccessを貼り付けます。 デフォルトのポリシーは、v2SDKでは機能しません。 さらに説明が必要な場合はお知らせください。

iot urlは、iotv2が表示されなくなり、まもなく削除されるため、使用するURLです。 pythonとiotsdkは互いに独立しており、関係はありません。 iotv1はpython2および3をサポートしますが、iotv2はpython3のみをサポートします。iotsdkは相互互換性または下位互換性がなく、v2apiのドキュメントはここにあります。

同じ問題があります。上記のポリシー@jmklixを使用し、新しい証明書を手動で作成し、それをIoT Thingとポリシーにリンクして、次のように.pem、秘密鍵、ルートCAをダウンロードしました。

python3 shadow.py --endpoint xxxxxxxxxx-ats.iot.us-east-2.amazonaws.com --root-ca root-CA.crt --cert 726290b105-certificate.pem.crt --key 726290b105-private.pem.key --thing-name MyThingName

shadow.pyの例では、-certは.pem形式である必要があるため、726290b105-certificate.pemも試してみました。

pubsub.pyの例でも同じエラーが発生します。

Python3でRaspberrypiを使用しています。

PyPIを使用してインストールし、ソースを使用してインストールしてみました。

このエラーは、shadow.pyの例のconnected_future.result()で発生します。

ipc_greengrass.pyサンプルに似たMQTTを使用して公開するコンポーネントがあり、うまく機能します。

私の疑いは、キー、証明書、および--rood-caを含めるときに何か間違ったことをしていることです。 私はファイラーのフォーマットを再確認しましたが。 このエラーが発生します：

Traceback (most recent call last):

今はとても馬鹿げていると感じています。私にとってのエラーは、IoTコンソールで証明書をアクティブ化していないことでした。 これは愚かなことですが、他の人を助けることができます

@hackaprende行き詰まった場所への解決策を共有してくれてありがとう。

これが将来の検索者に役立つ場合に備えて、ここに投稿すると、エラーawscrt.exceptions.AwsCrtError: AWS_ERROR_MQTT_UNEXPECTED_HANGUP: The connection was closed unexpectedly.も発生しました。私にとっては、AWSIoTモノの証明書を_アクティブ化_していないことがわかりました。 それを作成した後、それをアクティブ化するための別のステップがあります。
