.NET WebApi使用Swagger

1.新建WebApi 项目

2.引用Swagger 包

3.创建项目XML注释文档

在项目App_Start文件夹下的SwaggerConfig.cs类中加入

c.IncludeXmlComments(System.String.Format(@"{0}/bin/WebApiSwaggerDemo.XML", System.AppDomain.CurrentDomain.BaseDirectory));

4.转中文

/////    <summary>
///// 中文转换
/////    </summary>
//var SwaggerTranslator = (function () {
//    //定时执行检测是否转换成中文,最多执行500次  即500*50/1000=25s
//    var iexcute = 0,
//        //中文语言包

或者

6.自定义 HTTP Header （oauth2.0 请求）

在开发API时常常需要验证权限，验证参数放在Http请求头中是再好不过了。WebAPI配合过滤器验证权限即可

首先我们需要创建一个 IOperationFilter 接口的类。IOperationFilter：

/// <summary>
    /// swagger 增加 AUTH 选项
    /// </summary>
    public class HttpAuthHeaderFilter : IOperationFilter
    {
        /// <summary>
        /// 应用
        /// </summary>
        /// <param name="operation"></param>
        /// <param name="schemaRegistry"></param>
        /// <param name="apiDescription"></param>
        public void Apply(Operation operation, SchemaRegistry schemaRegistry, ApiDescription apiDescription)

        {
            if (operation.parameters == null)
                operation.parameters = new List<Parameter>();
            var filterPipeline = apiDescription.ActionDescriptor.GetFilterPipeline(); //判断是否添加权限过滤器
            var isAuthorized = filterPipeline.Select(filterInfo => filterInfo.Instance).Any(filter => filter is IAuthorizationFilter); //判断是否允许匿名方法
            var allowAnonymous = apiDescription.ActionDescriptor.GetCustomAttributes<AllowAnonymousAttribute>().Any();
            if (isAuthorized && !allowAnonymous)
            {
                operation.parameters.Add(new Parameter { name = "Authorization", @in = "header", description = "安全", required = false, type = "string" });
            }
        }
    }

SwaggerConfig.cs 配置中加入  c.OperationFilter<HttpAuthHeaderFilter>();

using System.Web.Http;
using WebActivatorEx;
using WebApiDemo;
using Swashbuckle.Application;
using System.Linq;

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

namespace WebApiDemo
{
    /// <summary>
    ///
    /// </summary>
    public class SwaggerConfig
    {
        /// <summary>
        ///
        /// </summary>
        public static void Register()
        {
            var thisAssembly = typeof(SwaggerConfig).Assembly;

            GlobalConfiguration.Configuration
                .EnableSwagger(c =>
                    {
                        // By default, the service root url is inferred from the request used to access the docs.
                        // However, there may be situations (e.g. proxy and load-balanced environments) where this does not
                        // resolve correctly. You can workaround this by providing your own code to determine the root URL.
                        //
                        //c.RootUrl(req => GetRootUrlFromAppConfig());

                        // If schemes are not explicitly provided in a Swagger 2.0 document, then the scheme used to access
                        // the docs is taken as the default. If your API supports multiple schemes and you want to be explicit
                        // about them, you can use the "Schemes" option as shown below.
                        //
                        //c.Schemes(new[] { "http", "https" });

                        // Use "SingleApiVersion" to describe a single version API. Swagger 2.0 includes an "Info" object to
                        // hold additional metadata for an API. Version and title are required but you can also provide
                        // additional fields by chaining methods off SingleApiVersion.
                        //
