世态人情，比明月清风更饶有滋味；可作书读，可当戏看。书上的描摹，戏里的扮演，即使栩栩如生，究竟只是文艺作品；人情世态，都是天真自然的流露，往往超出情理之外，新奇得令人震惊，令人骇怪，给人以更深刻的效益，更奇妙的娱乐。惟有身处卑微的人，最有机缘看到世态人情的真相，而不是面对观众的艺术表演。

一、ACPF UI 简介
Awesome Chrome Presentation Foundation UI：简称 ACPF UI，基于 CefSharp 库进行插件化封装，它提供接口的默认实现（预设）和常用 Attribute 特性（注解），开发者可以开箱即用，无需过多配置即可使用 Web 技术快速构建一个桌面应用。
应用场景：WPF 嵌入式浏览器解决方案。
该框架的核心是：通过解耦来简化配置，降低开发难度。例如，类似于 SpringBoot 通过注解实现依赖注入和控制反转等功能，ACPF UI 提供 Attribute 实现同样的效果，从而提高应用程序的灵活性和可维护性。
如果您想使用 Vue 等前端技术栈构建 WPF 桌面应用，并且使用的是 CefSharp 实现，那么您可以考虑使用 ACPF UI。
如果该框架并不能为您提供解决方案，请考虑使用其他成熟框架例如 Electron/Tauri/WinFormium 等。
二、ACPF 插件模块
安装 CefSharp.Wpf ，这里使用的版本是 119.1.20，
三、Attribute 特性
JavascriptObjectAttribute 用于导出 .net 方法为 js 对象，其他 ConfigurationAttribute 用于注入对应的配置项，
1、JavascriptObjectAttribute
using System;
namespace AwesomeChromePresentationFoundationUI.Attributes
{
/// <summary>
/// 该注解代表将类作为 JavascriptObject 导出
/// </summary>
[AttributeUsage(AttributeTargets.Class, AllowMultiple = false)]
public class JavascriptObjectAttribute : Attribute
{
/// <summary>
/// 名字，通常为驼峰命名
/// </summary>
public string Name { get; set; }
}
}
2、BrowserConfigurationAttribute
using System;
namespace AwesomeChromePresentationFoundationUI.Attributes
{
/// <summary>
/// 自定义 Browser 配置注解
/// </summary>
[AttributeUsage(AttributeTargets.Class, AllowMultiple = false)]
public class BrowserConfigurationAttribute : Attribute
{
}
}
3、CefConfigurationAttribute
using System;
namespace AwesomeChromePresentationFoundationUI.Attributes
{
/// <summary>
/// 自定义 Cef 配置注解
/// </summary>
[AttributeUsage(AttributeTargets.Class, AllowMultiple = false)]
public class CefConfigurationAttribute : Attribute
{
}
}
4、MainViewConfigurationAttribute
using System;
namespace AwesomeChromePresentationFoundationUI.Attributes
{
/// <summary>
/// 自定义 BaseForm 配置注解
/// </summary>
[AttributeUsage(AttributeTargets.Class, AllowMultiple = false)]
public class MainViewConfigurationAttribute : Attribute
{
}
}
四、Reflections 反射
AttributeUtil 用于扫描自定义 Attribute 的类，
1、AttributeUtil
using System;
using System.Linq;
using System.Reflection;
namespace AwesomeChromePresentationFoundationUI.Reflections
{
public class AttributeUtil
{
/// <summary>
/// 找到第一个带注解的类
/// </summary>
/// <typeparam name="T"></typeparam>
/// <returns></returns>
public static Type FindFirstAnnotatedClass<T>() where T : Attribute
{
return AppDomain.CurrentDomain.GetAssemblies()
.SelectMany(a => a.GetTypes())
.Where(t => t.IsClass && t.GetCustomAttribute<T>() != null)
.FirstOrDefault();
}
/// <summary>
/// 找到第一个带注解的类
/// </summary>
/// <typeparam name="T"></typeparam>
/// <typeparam name="S">继承自S类</typeparam>
/// <returns></returns>
public static Type FindFirstAnnotatedClass<T, S>() where T : Attribute
{
return AppDomain.CurrentDomain.GetAssemblies()
.SelectMany(a => a.GetTypes())
.Where(t => t.IsClass && t.GetCustomAttribute<T>() != null && typeof(S).IsAssignableFrom(t))
.FirstOrDefault();
}
}
}
五、Interfaces 接口
提供接口，引导自定义接口实现，
1、IBrowserConfiger
using AwesomeChromePresentationFoundationUI.Configs;
namespace AwesomeChromePresentationFoundationUI.Interfaces
{
public interface IBrowserConfiger
{
BrowserConfiguration CreateCustomBrowserConfiguration();
}
}
2、ICefConfiger
using AwesomeChromePresentationFoundationUI.Configs;
namespace AwesomeChromePresentationFoundationUI.Interfaces
{
public interface ICefConfiger
{
CefConfiguration CreateCustomCefConfiguration();
}
}
3、IMainViewConfiger
using AwesomeChromePresentationFoundationUI.Configs;
namespace AwesomeChromePresentationFoundationUI.Interfaces
{
public interface IMainViewConfiger
{
MainViewConfiguration CreateCustomBaseFormConfiguration();
}
}
4、IConfigurationExecuter
namespace AwesomeChromePresentationFoundationUI.Interfaces
{
public interface IConfigurationExecuter
{
void Execute();
}
}
5、CefConfigurationExecuter
using AwesomeChromePresentationFoundationUI.Configs;
using CefSharp;
namespace AwesomeChromePresentationFoundationUI.Interfaces.Implements
{
public class CefConfigurationExecuter : IConfigurationExecuter
{
public void Execute()
{
CefConfiguration configuration = DefaultICefConfiger.CreateCustomCefConfiguration();
Cef.Initialize(
configuration.CefSettings,
performDependencyCheck: configuration.PerformDependencyCheck,
browserProcessHandler: configuration.BrowserProcessHandler
);
}
}
}
六、Configs 配置
提取一些必要配置项并设置默认值，
1、BrowserConfiguration
using AwesomeChromePresentationFoundationUI.Constants;
namespace AwesomeChromePresentationFoundationUI.Configs
{
public class BrowserConfiguration
{
/// <summary>
/// 默认编码
/// </summary>
public string DefaultEncoding { get; set; }
/// <summary>
/// 加载 URL
/// </summary>
public string HomeUrl { get; set; }
public BrowserConfiguration()
{
this.DefaultEncoding = SystemConstant.BROWSER_DEFAULT_ENCODING;
this.HomeUrl = SystemConstant.BROWSER_DEFAULT_LOAD_URL;
}
}
}
2、CefConfiguration
using CefSharp;
using CefSharp.SchemeHandler;
using CefSharp.Wpf;
using System;
using System.IO;
namespace AwesomeChromePresentationFoundationUI.Configs
{
public class CefConfiguration
{
/// <summary>
/// 默认前端文件夹
/// </summary>
private string _defaultFrontendFolderPath;
public CefSettingsBase CefSettings { get; set; }
public bool PerformDependencyCheck { get; set; }
public IBrowserProcessHandler BrowserProcessHandler { get; set; }
public CefConfiguration()
{
CreateDefaultFrontendFolderPath();
// Pseudo code; you probably need more in your CefSettings also.
var settings = new CefSettings()
{
Locale = "zh-CN",
// Increase the log severity so CEF outputs detailed information, useful for debugging
LogSeverity = LogSeverity.Verbose,
//By default CefSharp will use an in-memory cache, you need to specify a Cache Folder to persist data
CachePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "CefSharp\\Cache")
};
//Example of setting a command line argument
//Enables WebRTC
// - CEF Doesn't currently support permissions on a per browser basis see https://bitbucket.org/chromiumembedded/cef/issues/2582/allow-run-time-handling-of-media-access
// - CEF Doesn't currently support displaying a UI for media access permissions
//
//NOTE: WebRTC Device Id's aren't persisted as they are in Chrome see https://bitbucket.org/chromiumembedded/cef/issues/2064/persist-webrtc-deviceids-across-restart
settings.CefCommandLineArgs.Add("enable-media-stream");
//https://peter.sh/experiments/chromium-command-line-switches/#use-fake-ui-for-media-stream
settings.CefCommandLineArgs.Add("use-fake-ui-for-media-stream");
//For screen sharing add (see https://bitbucket.org/chromiumembedded/cef/issues/2582/allow-run-time-handling-of-media-access#comment-58677180)
settings.CefCommandLineArgs.Add("enable-usermedia-screen-capturing");
//Disable GPU Acceleration
settings.CefCommandLineArgs.Add("disable-gpu");
// Don't use a proxy server, always make direct connections. Overrides any other proxy server flags that are passed.
// Slightly improves Cef initialize time as it won't attempt to resolve a proxy
settings.CefCommandLineArgs.Add("no-proxy-server");
settings.RegisterScheme(new CefCustomScheme
{
SchemeName = "http",
DomainName = "yushanma.acpf",
SchemeHandlerFactory = new FolderSchemeHandlerFactory(rootFolder: this._defaultFrontendFolderPath,
hostName: "yushanma.acpf", //Optional param no hostname/domain checking if null
defaultPage: "index.html") //Optional param will default to index.html
});
this.CefSettings = settings;
this.PerformDependencyCheck = true;
this.BrowserProcessHandler = null;
}
/// <summary>
/// 创建默认前端文件夹
/// </summary>
private void CreateDefaultFrontendFolderPath()
{
string frontendFolderPath = Path.Combine(Directory.GetCurrentDirectory(), "Frontend");
if (!Directory.Exists(frontendFolderPath))
{
Directory.CreateDirectory(frontendFolderPath);
