今、私はEclipseで別のAndroidアプリケーションを作成しました（アクティビティは単純なボタンを備えた単純なアクティビティではなく、コード内のリスナーはそのボタンに接続されています。とにかく、このアクティビティを実行し、AsyncTaskを実行するオンクリックリスナーで実行します上記の HTTPS 呼び出しを逐語的に呼び出すと、400 応答が返されます. これはなぜですか? HTTPS を実行するためのすべての手順に従っていると確信しているので、私は完全に混乱しています. うまくいかないので、明らかに完全にはわかりません. しかし、それは動作しますストレート Java アプリケーション. なぜこれが? 助けてください!!!!

Android のアクティビティは次のとおりです。

OK 人々はこれを確認してください 非常に単純にしてください - 悪いのはスクリプトではありません.. あなたの Web.Config には、400 エラーが応答していない Web ページをロードするように要求している HTTP 競合がある可能性があります。したがって、スクリプトが優れていることがわかっているいくつかのマイナーな詳細を確認する必要があるため、設定と、コンピューターとブラウザーの応答方法を確認する必要があります...

解決するには、まず DNS キャッシュをクリアして Cookie を削除します。2. サービスの場合、webHttpBinding を basicHttpBinding に置き換えます 3. ヘッダー行が長くないことを確認します

シンプルに保つことを忘れないでください さらに支援が必要な場合は、私にメールでお問い合わせください
