Windows-Auto-Night-Mode扩展案例实现自定义天气触发主题切换Windows-Auto-Night-Mode是一款能自动切换Windows 10/11明暗主题的工具默认通过时间或日出日落触发切换。本文将介绍如何扩展其功能实现基于天气条件如雨天、高温自动切换主题的高级场景。实现思路要实现天气触发主题切换需完成三个核心步骤获取天气数据、定义触发规则、集成到主题切换逻辑。项目现有架构已提供灵活的扩展点主要涉及以下模块规则引擎AutoDarkModeSvc/Interfaces/IAutoDarkModeGovernor.cs 定义了主题切换规则接口可通过实现该接口添加天气触发逻辑配置系统AutoDarkModeLib/Configs/AdmConfig.cs 用于存储天气API密钥和触发阈值等自定义设置主题切换AutoDarkModeSvc/Core/ThemeManager.cs 负责实际的主题切换操作天气数据获取模块首先需要添加天气数据获取功能。推荐使用和风天气API或高德天气API这些服务提供免费额度且支持国内城市。在项目中创建WeatherService类// AutoDarkModeSvc/Services/WeatherService.cs using System.Net.Http; using System.Text.Json; using System.Threading.Tasks; public class WeatherService { private readonly HttpClient _httpClient; private readonly string _apiKey; public WeatherService(string apiKey) { _httpClient new HttpClient(); _apiKey apiKey; } public async TaskWeatherData GetCurrentWeather(string cityId) { var response await _httpClient.GetAsync( $https://devapi.qweather.com/v7/weather/now?location{cityId}key{_apiKey}); response.EnsureSuccessStatusCode(); var json await response.Content.ReadAsStringAsync(); return JsonSerializer.DeserializeWeatherData(json); } } public class WeatherData { public string Code { get; set; } public Now Now { get; set; } } public class Now { public string Text { get; set; } // 天气现象文字 public string Temp { get; set; } // 温度 }天气触发规则实现实现IAutoDarkModeGovernor接口创建天气触发规则// AutoDarkModeSvc/Governors/WeatherGovernor.cs using AutoDarkModeLib; using AutoDarkModeSvc.Events; using AutoDarkModeSvc.Interfaces; public class WeatherGovernor : IAutoDarkModeGovernor { public Governor Type Governor.Weather; private readonly WeatherService _weatherService; private readonly AdmConfig _config; public WeatherGovernor(AdmConfig config) { _config config; _weatherService new WeatherService(config.WeatherApiKey); } public GovernorEventArgs Run() { var weather _weatherService.GetCurrentWeather(_config.CityId).Result; var isDarkMode ShouldEnableDarkMode(weather); return new GovernorEventArgs { Theme isDarkMode ? Theme.Dark : Theme.Light, Source Type.ToString(), Enabled true }; } private bool ShouldEnableDarkMode(WeatherData weather) { // 雨天或温度低于15度时启用暗色模式 return weather.Now.Text.Contains(雨) || int.Parse(weather.Now.Temp) 15; } public void EnableHook() { } public void DisableHook() { } }配置扩展扩展配置模型以支持天气设置// AutoDarkModeLib/Configs/AdmConfig.cs public class AdmConfig { // 现有配置... public string WeatherApiKey { get; set; } ; public string CityId { get; set; } 101010100; // 默认北京 public int WeatherDarkThreshold { get; set; } 15; // 温度阈值 public Liststring DarkWeatherConditions { get; set; } new Liststring { 雨, 雪, 阴 }; }UI配置界面添加配置界面让用户输入API密钥和设置触发条件!-- AutoDarkModeApp/Views/WeatherSettingsPage.xaml -- Page xmlnshttp://schemas.microsoft.com/winfx/2006/xaml/presentation xmlns:xhttp://schemas.microsoft.com/winfx/2006/xaml x:ClassAutoDarkModeApp.Views.WeatherSettingsPage StackPanel Margin20 TextBlock Text天气触发设置 FontSize18 Margin0 0 0 20/ TextBox HeaderAPI密钥 Text{Binding WeatherApiKey} Margin0 10/ TextBox Header城市ID Text{Binding CityId} Margin0 10/ StackPanel OrientationHorizontal Margin0 10 TextBlock Text温度阈值: VerticalAlignmentCenter/ Slider Minimum0 Maximum30 Value{Binding WeatherDarkThreshold} Width200 Margin10/ TextBlock Text{Binding WeatherDarkThreshold}°C VerticalAlignmentCenter/ /StackPanel CheckBox Content雨天触发暗色模式 IsChecked{Binding DarkWeatherConditions.Contains(雨)}/ CheckBox Content雪天触发暗色模式 IsChecked{Binding DarkWeatherConditions.Contains(雪)}/ CheckBox Content阴天触发暗色模式 IsChecked{Binding DarkWeatherConditions.Contains(阴)}/ /StackPanel /Page集成到主题管理器修改主题管理器以支持天气触发规则// AutoDarkModeSvc/Core/ThemeManager.cs public class ThemeManager { private ListIAutoDarkModeGovernor _governors; public ThemeManager(AdmConfig config) { _governors new ListIAutoDarkModeGovernor { new TimeSwitchGovernor(config), new NightLightGovernor(config), new WeatherGovernor(config) // 添加天气规则 }; } public Theme GetDesiredTheme() { // 现有逻辑... foreach (var governor in _governors) { if (governor is WeatherGovernor weatherGov !string.IsNullOrEmpty(config.WeatherApiKey)) { var result weatherGov.Run(); if (result.Enabled) return result.Theme; } } return defaultTheme; } }效果演示配置完成后系统将根据天气条件自动切换主题当检测到雨天时自动切换到暗色模式当温度低于设定阈值时保持暗色模式晴天且温度适宜时切换到亮色模式用户可以在设置界面随时调整触发条件满足个性化需求。此扩展充分利用了项目现有的规则引擎架构保持了代码的可维护性和扩展性。总结通过本文介绍的方法我们成功扩展了Windows-Auto-Night-Mode的功能实现了基于天气条件的主题自动切换。关键步骤包括创建天气数据服务获取实时天气信息实现IAutoDarkModeGovernor接口定义切换规则扩展配置模型和UI界面集成到现有主题管理系统这种扩展方式可以应用于其他触发条件如系统负载、电池状态等为Windows主题切换带来更多可能性。完整代码可参考项目扩展示例库。创作声明：本文部分内容由AI辅助生成（AIGC），仅供参考
