Я выполняю миграцию загрузчика файлов пользовательской схемы, который я написал в CefSharp (Chromium Embedded Web Host для Windows Forms).Я не смог заставить его работать на другом сервере.Я экспериментирую с новыми конфигурациями, но я не уверен, где во время выполнения мне нужно проверить, чтобы убедиться, что папки, которые я надеюсь найти в моих html-файлах, являются реальными целями.
CefPrimeFiles - это rootFolder.ScanditPage - это папка вниз, представляющая местоположение html, поэтому целевым URL является http://localhost/ScanditPage/ScanditTest.html.
. RootFolder для FolderSchemeHandlerFactory - C: \ Users \ romero.ryan \ Documents \ Visual Studio 2015 \ Projects \WinHostScandit1 \ WebHostOnDisk \ CefPrimeFiles.
У объекта браузера есть .Address дает мне целевой URL.Я предполагаю, что Cef. * Будет содержать информацию о зарегистрированных схемах, но пока я не нашел ссылку при отладке.
Вот рабочий пример (кроме ошибки формы при загрузке целевого файла HTML):
