使用.NET6实现动态API_ASP.NET_

 static class ServiceExtension { internal static WebApplicationBuilder AddKApp(this WebApplicationBuilder builder, Action? action = null) { var option = new AppOption(); action?.Invoke(option); ... AddDynamicApi(mvcBuilder, option);//添加动态api return builder; } private static void AddDynamicApi(IMvcBuilder builder, AppOption option) { builder.ConfigureApplicationPartManager(m => { m.ApplicationParts.Add(new AssemblyPart(typeof(IService).Assembly)); foreach (var item in option.Modules) { item.Initialize();//初始化模块 //将模块添加到ApplicationParts，这样才能发现服务类 var assembly = item.GetType().Assembly; m.ApplicationParts.Add(new AssemblyPart(assembly)); } m.FeatureProviders.Add(new ApiFeatureProvider()); }); builder.Services.Configure(o => { o.Conventions.Add(new ApiConvention()); }); } } //判断服务类型是否为Controller class ApiFeatureProvider : ControllerFeatureProvider { protected override bool IsController(TypeInfo typeInfo) { if (!typeof(IService).IsAssignableFrom(typeInfo) || !typeInfo.IsPublic || typeInfo.IsAbstract || typeInfo.IsGenericType) return false; return true; } } class ApiConvention : IApplicationModelConvention { public void Apply(ApplicationModel application) { foreach (var controller in application.Controllers) { var type = controller.ControllerType; if (typeof(IService).IsAssignableFrom(type)) { ConfigureApiExplorer(controller); ConfigureSelector(controller); } } } ... //构造路由模板 private string GetRouteTemplate(ActionModel action) { if (action.Attributes != null && action.Attributes.Count > 0) { foreach (var item in action.Attributes) { if (item is RouteAttribute attribute) { return attribute.Path;//返回自定义路由 } } } var routeTemplate = new StringBuilder(); //routeTemplate.Append("api"); var names = action.Controller.ControllerType.Namespace.Split('.'); if (names.Length > 2) { //支持不同模块相同类名，添加命名空间模块名作前缀 routeTemplate.Append(names[^2]); } // Controller var controllerName = action.Controller.ControllerName; if (controllerName.EndsWith("Service")) controllerName = controllerName[0..^7]; routeTemplate.Append($"/{controllerName}"); // Action var actionName = action.ActionName; if (actionName.EndsWith("Async")) actionName = actionName[..^"Async".Length]; if (!string.IsNullOrEmpty(actionName)) routeTemplate.Append($"/{actionName}"); return routeTemplate.ToString(); } }

 KHost.Run(args, o => { o.Modules.Add(new TestModule());//添加模块 }); class TestModule : IModule { public void Initialize() { } } public class TestService : IService { public string GetName(string name) { return $"Hello {name}"; } public string SaveData(string data) { return $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} {data}"; } [Route("api/test")] public string GetCustMethod(string id) { return id; } }
