我的代碼：如何查看Qt中的網絡接口類型？
CheckNetwork.h

QNetworkInterface *network_interface;

我的問題是，我沒有辦法檢查網絡接口的類型，如果是「有線或無線的」是「在線」，以防止網絡管理器自動啓動，如果用戶沒有因爲此驗證連接的連接網絡（QNetworkConfigurationManager :: CanStartAndStopInterfaces）：
network_configuration_manager->defaultConfiguration();
if(!network_configuration_manager->isOnline()){
network_configuration_manager->deleteLater();
return;
}
這完全適用於無線連接，但是因爲沒有爲連接ca找到默認配置通過此檢查，網絡管理員無法繼續......換句話說，如果網絡連接處於活動狀態（不是ping或查詢諸如Google之類的服務器），如何檢查連接電纜。我也讀過一些以前的版本存在類似的bug。在這個版本的Qt中，例如，他的郵箱中有錯誤，那麼它會是一個錯誤？會有人的信息？謝謝
感謝您的反應和你的時間，但對於第1步你推薦我QT發現沒有配置用於「有線」類型的接口。使用defautlconfiguration（）或allconfiguration（）可以返回任何類似於我上面的textEdit的內容（我指定我根本不想查詢任何內容），只是沒有爲所有類型的「有線」網絡配置找到配置。我終於決定使用回覆來處理錯誤（QNetworkReply，使用他的錯誤信號，似乎我的無線類型接口不再自動連接時執行我的QNetworkManager的實例） –
爲此我想這樣做就足夠了，但是我我想知道這個問題在哪裏，我認爲QT最終會產生內部問題。糾正我或給我一個地方，看看我是否錯了我可能不是因爲它應該。再次感謝你 –
這就是我開始做的，它在Linux中對我有用，但是當我在Windows中測試它時，它失敗了！QNetworkSession.interface（）。isValid（）在Windows中是False這樣的！ – BuvinJ
