.Net WebApi— SwaggerUI配置

最近新公司用了特别老的技术【Web 服务 .asmx文件 做WebService服务】，而WebApi早就流行四五年了；

实在太过于简陋，关键其他系统对接的同事，经常说对接不上，如果接口过多确实不方便接口管理，所以最终决定重新搭建wepai 方便后续接口开发和管理。

一、创建ASP.NET WEB 应用程序 选择空的模板
二、在项目中添加文件夹 App_Start (wepapi 启动项配置文件)
三、在项目中添加文件夹 Controller (用来编写Controller 也就接口)
四、在项目中添加文件夹 Script (用来做文档SwaggerUI的汉化版处理)

还得配置NuGet包 Swashbuckle、Swashbuckle.Core

App_Start文件夹
配置 WebApiConfig

using FIS.WebService.App_Start;
using Newtonsoft.Json.Converters;
using Swashbuckle.Application;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;

namespace FIS.WebService
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.MapHttpAttributeRoutes();
            //路由：匹配到action
            config.Routes.MapHttpRoute(
                name: "FisApi",
                routeTemplate: "{controller}/{action}",
                defaults: new { id = RouteParameter.Optional }
            );
            config.Routes.MapHttpRoute(
                name: "swagger_root",
                routeTemplate: "",
                defaults: null,
                constraints: null,
                handler: new RedirectHandler((message => message.RequestUri.ToString()), "swagger")
            );

            //移除XML格式，采用Json进行数据交互
            config.Formatters.XmlFormatter.SupportedMediaTypes.Clear();

            //处理DateTime类型序列化后含有T的问题
            config.Formatters.JsonFormatter.SerializerSettings.Converters.Insert(0, new IsoDateTimeConverter());

            //config.Filters.Add(new ModeActionFilter());

            //添加全局异常处理器
            //config.Filters.Add(new MyAttribute());
        }

    }
}

添加 SwaggerConfig

using System.Web.Http;
using WebActivatorEx;
using FIS.WebService;
using Swashbuckle.Application;
using FIS.WebService.App_Start;
using Swashbuckle.Swagger;
using System.Linq;

[assembly: PreApplicationStartMethod(typeof(SwaggerConfig), "Register")]

namespace FIS.WebService
{
    public class SwaggerConfig
    {
        public static void Register()
        {
            var thisAssembly = typeof(SwaggerConfig).Assembly;

            GlobalConfiguration.Configuration
                .EnableSwagger(c =>
                {

                    c.SingleApiVersion("v1", "Fis WebApi");

                    //显示api接口注释 
                    var xmlFile = string.Format(@"{0}\bin\FIS.WebService.xml", System.AppDomain.CurrentDomain.BaseDirectory);
                    if (System.IO.File.Exists(xmlFile))
                    {
                        c.IncludeXmlComments(xmlFile);
                    }
                    c.CustomProvider((defaultProvider) => new SwaggerControllerDescProvider(defaultProvider, xmlFile));

                    //设置分组名字
                    c.GroupActionsBy(apiDesc =>
                    apiDesc.GetControllerAndActionAttributes<ControllerGroupAttribute>().Any() ?
                    apiDesc.GetControllerAndActionAttributes<ControllerGroupAttribute>().First().GroupName + " - " +
                    apiDesc.GetControllerAndActionAttributes<ControllerGroupAttribute>().First().Useage : "暂未设置ControllGroup");
                })
                .EnableSwaggerUi(c =>
                {
                    c.DocumentTitle("Swagger UI");
                    //加载汉化的js文件
                    c.InjectJavaScript(System.Reflection.Assembly.GetExecutingAssembly(), "FIS.WebService.Script.swagger.js");

                });
        }
    }
}

using System.Web.Routing;
using System.Web.Security;
using System.Web.SessionState;

        {
            AreaRegistration.RegisterAllAreas();
            GlobalConfiguration.Configure(WebApiConfig.Register);
            //取消xml
            GlobalConfiguration.Configuration.Formatters.XmlFormatter.SupportedMediaTypes.Clear();
        }

        protected void Session_Start(object sender, EventArgs e)
        {

        }

        protected void Application_BeginRequest(object sender, EventArgs e)
        {

        }

        protected void Application_AuthenticateRequest(object sender, EventArgs e)
