現在、woocommerce APIに取り組んでいます。私は、改造を使用してAPIを統合する必要があります。 Webサイトはです。HTTPです。このため、HTTPの基本認証は、キーが傍受の影響を受けやすいため、プレーンなHTTPに比べて使用できません。 APIでは、OAuth 1.0aの「片足式」認証を使用して、APIキーをインターセプトできないようにしています。私はthis articalを経由して、httpでどのOAuthメトードを使用するのかを理解しています。Oouth 1.0aを実装する方法woocomerceのApoをアンドロイドで使用する
私はScribeを使用してapiを正常に実装しましたが、私はGogglingの後に私はInterceptorがJake WhartonのOauth1SigningInterceptorであることを発見した後、改造を使用してAPIを実装したいと考えています。
ので、私は以下の成功応答を返す
スクライブを使用して呼び出した場合、同じAPIの認証のための改造ではなく、API呼び出しの戻り

私はAPIを呼び出す方法であると実装（ジェイクウォートンOauth1SigningInterceptorから改変）

ウーコマースバージョンはバージョン2.6.4 APIバージョンは、いずれかが私が私が改造自体でこれを実装するこの問題を解決するのに役立つことができV1
