request メソッドを使用HttpURLConnectionすると、 「 https://www.myexample.com/login?u=test&p=test123GET 」で REST API に接続できますが、「 http://dev.myexample.com/login?u=test&pでは接続できません」=test123 ".

同じデバイスのデフォルトの Android ブラウザで「壊れた」URL を確認できます。期待どおりのXML応答が得られるためECONNREFUSED、アプリ内で受信している理由がわかりません。この問題を自分で解決したいのですが、何が問題なのかさえわかりません。何か案は？

HttpUrlConnection接続を行っているものです。443ポートが使用されていることに気付きました。http://アドレスを指定したため、これは問題です。

http6.0 Android アップデートでは、すべてのリクエストをに変更するオーバーライドがありましたhttps。何かが起きていることを障害ラインから知る必要がありました。

うまくいけば、誰かが私の見落としから利益を得ることができます.
