Facebookのキャプチャ画像をC＃で取得してから、アプリに表示して、応答をFacebookに送信しようとしています。私のアプリは基本的にFacebookと通信しますが、しばらくするとキャプチャを要求します。キャプチャを入力する機能を組み込み、webclient を使用して Facebook に送信すると、機能したという応答が得られました。しかし、もう一度データをクエリしようとすると、再びキャプチャ リンクに誘導され、サイクルが続きます。
キャプチャを入力した後続のリクエストにどのように情報を添付するか、またはキャプチャ応答ヘッダーから返されたどの情報を新しいリクエストに添付する必要があるかがわかりません。
下手な英語でごめんなさい。メッセージが伝わったと思います。
