MicroService4Net快速搭建微服务（二）

对于config的配置，进行了自定义处理，主要是控制器的分离，以及控制器和action路由响应处理，如下：

static void Main(string[] args)        {            const int apiport = 65511;            var microService = new MicroService(                    port: apiport,                    serviceDisplayName: string.Format("直播系统API服务：{0}", apiport),                    serviceName: "xxLivePlatform",                    configure: x =>                    {                        x.Routes.MapHttpRoute(                             name: "DefaultApi",                             routeTemplate: "api/{controller}/{action}/{id}",                             defaults: new { id = RouteParameter.Optional }                        );                        x.Services.Replace(typeof(IAssembliesResolver), new Custom.ControllerResolver());                        x.Services.Replace(typeof(IHttpControllerSelector), new Custom.CHttpControllerSelector(x));                        x.Services.Replace(typeof(IHttpActionSelector), new Custom.CControllerActionSelector());                        x.Services.Replace(typeof(IHttpActionInvoker), new Custom.CControllerActionInvoker());                        x.MessageHandlers.Add(new Custom.CDelegatingHandler());                    },                    useCors: true);            microService.Run(args);        }

ControllerResolver：

using System;using System.Collections.Generic;using System.Reflection;using System.Web.Http.Dispatcher;namespace ApiService.Custom{    /// <summary>    /// 装载控制器    /// </summary>    internal class ControllerResolver : DefaultAssembliesResolver    {        public override ICollection<Assembly> GetAssemblies()        {            string[] dll = { "Controller" };            foreach (var d in dll)            {                try                {                    AppDomain.CurrentDomain.Load(d + ",Version=1.0.0.0,PublicKeyToken=null");                }                catch (System.IO.FileNotFoundException e)                {                    Tools.LogHelp.Log(string.Format("未找到{0}.dll，程序集：Exception：{1}", d, e.Message));                }                catch (BadImageFormatException e)                {                    Tools.LogHelp.Log(string.Format("{0}.dll不是有效的程序集 或 程序集版本不匹配，Exception：{1}", d, e.Message));                }                catch (Exception e)                {                    Tools.LogHelp.Log(e.Message);                }            }            return base.GetAssemblies();        }    }}

CHttpControllerSelector：

/// <summary>    /// 自定义控制器选择    /// </summary>    internal class CHttpControllerSelector : DefaultHttpControllerSelector    {        public CHttpControllerSelector(HttpConfiguration configuration)            : base(configuration)        {        }        public override HttpControllerDescriptor SelectController(HttpRequestMessage request)        {            HttpControllerDescriptor decriptor = null;            try            {                decriptor = base.SelectController(request);            }            catch (HttpResponseException ex)            {                var code = ex.Response.StatusCode;                if (code == HttpStatusCode.NotFound || code == HttpStatusCode.MethodNotAllowed)                {                    //var msg = CMessage.makemsg("请求资源不存在", -1, ex.Response.Content.ReadAsAsync<object>().Result);                    var msg = CMessage.makemsg("请求资源不存在001", -1);                    ex.Response.Content = new StringContent(msg);                }                throw;            }            return decriptor;        }    }

CControllerActionSelector：

using System.Net;using System.Net.Http;using System.Web.Http;using System.Web.Http.Controllers;namespace ApiService.Custom{    /// <summary>    /// 自定义Action选择    /// </summary>    internal class CControllerActionSelector : ApiControllerActionSelector    {        public override HttpActionDescriptor SelectAction(HttpControllerContext controllerContext)        {            HttpActionDescriptor decriptor = null;            try            {                decriptor = base.SelectAction(controllerContext);            }            catch (HttpResponseException ex)            {                var code = ex.Response.StatusCode;                if (code == HttpStatusCode.NotFound || code == HttpStatusCode.MethodNotAllowed)                {                    //var msg = CMessage.makemsg("请求资源不存在", -1, ex.Response.Content.ReadAsAsync<object>().Result);                    var msg = CMessage.makemsg("请求资源不存在002", -1);                    ex.Response.Content = new StringContent(msg);                }                throw;            }            return decriptor;        }    }}

CControllerActionInvoker：

using System.Net.Http;using System.Threading;using System.Threading.Tasks;using System.Web.Http.Controllers;namespace ApiService.Custom{    /// <summary>    /// 自定义Action调用    /// </summary>    internal class CControllerActionInvoker : ApiControllerActionInvoker    {        public override Task<HttpResponseMessage> InvokeActionAsync(HttpActionContext actionContext, CancellationToken cancellationToken)        {            var responseMessage = base.InvokeActionAsync(actionContext, cancellationToken);            var ex = responseMessage.Exception;            if (ex != null)            {                var baseException = ex.InnerExceptions[0];                var msg = CMessage.makemsg(baseException.Message, -1, ex.InnerExceptions);                return Task.Run(() => new HttpResponseMessage()                {                    Content = new StringContent(msg)                }, cancellationToken);            }            return responseMessage;        }    }}
