已通过注册自定义 Scheme Handler 修复了浏览器无法处理 mdx:// 协议的问题。
|
| 171 |
+
|
| 172 |
+
主要修改:
|
| 173 |
+
实现 MdxSchemeHandler: 在 e:\huggingface\WpfMdict\csharp\mdict\Services\MdxSchemeHandler.cs 中实现了 ISchemeHandlerFactory,用于处理 mdx:// 协议的请求。
|
| 174 |
+
|
| 175 |
+
Action entry: 提取 key 参数,调用 LibraryManager 查找并返回词条 HTML。
|
| 176 |
+
Action mdd / sound: 提取 key 参数,调用 LibraryManager 查找并返回资源文件(图片、CSS、JS、音频)。
|
| 177 |
+
MIME 类型: 根据文件后缀名自动判断返回的 MIME 类型。
|
| 178 |
+
更新 LibraryManager: 在 e:\huggingface\WpfMdict\csharp\mdict\Services\LibraryManager.cs 中添加了以下辅助方法:
|
| 179 |
+
|
| 180 |
+
GetHtml(string key): 遍历所有已加载的词典,查找并返回第一个匹配词条的 HTML 内容。
|
| 181 |
+
GetResource(string key): 遍历所有已加载的词典,查找并返回第一个匹配资源的字节数据。
|
| 182 |
+
注册 Scheme: 在 e:\huggingface\WpfMdict\csharp\mdict\App.xaml.cs 的 InitializeCef 方法中,注册了 mdx 协议:
|
| 183 |
+
|
| 184 |
+
C#
|
| 185 |
+
|
| 186 |
+
|
| 187 |
+
|
| 188 |
+
settings.RegisterScheme(new CefCustomScheme{ SchemeName = "mdx", SchemeHandlerFactory = new MdxSchemeHandlerFactory(), IsStandard = true, IsSecure = true, IsCorsEnabled = false});
|
| 189 |
+
验证:
|
| 190 |
+
构建状态: dotnet build 成功,无错误。
|
| 191 |
+
功能预期:
|
| 192 |
+
点击词典内的跳转链接(如 entry://key 被重写为 mdx://mdict.cn/service/entry?key=...)时,现在应该能正确加载目标词条。
|
| 193 |
+
词典中的图片、CSS、JS 等资源(链接如 mdx://mdict.cn/service/mdd?key=\style.css)现在应该能正确加载并显示。
|
| 194 |
+
不再出现 ERR_UNKNOWN_URL_SCHEME 错误。
|
| 195 |
+
请运行程序并测试点击词条链接或查看包含图片的词条,确认跳转和资源加载是否正常。
