ASP.NET WEB API 中 Swagger配置

第一步：下载nuget包

Install-Package Swashbuckle

第二步：选中启动项目操作如下

右键->属性->生成->勾选Xml文档文件

第三步：修改App_Start文件夹中SwaggerConfig配置

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

            GlobalConfiguration.Configuration
                .EnableSwagger(c =>
                {

                    c.SingleApiVersion("v1", "SntSoft.Web.Api");
                    //让swagger根据xml文档来解析
                    c.IncludeXmlComments(GetXmlCommentsPath(thisAssembly.GetName().Name));
                    c.IncludeXmlComments(GetXmlCommentsPath("SntSoft.Model.Entitys"));
                    //过滤此特性的接口不显示
                    c.DocumentFilter<HiddenApiFilter>();
                    //oauth2.0
                    c.OperationFilter<HttpAuthHeaderFilter>();
                    c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());

                    //获取控制器的注释方法类
                    c.CustomProvider((defaultProvider) => new SwaggerControllerDescProvider(defaultProvider, GetXmlCommentsPath(thisAssembly.GetName().Name)));

                    //swagger 分组
                    c.GroupActionsBy(apiDesc => apiDesc.GetControllerAndActionAttributes<ControllerGroupAttribute>().Any() ? apiDesc.GetControllerAndActionAttributes<ControllerGroupAttribute>().First().GroupName + "." + apiDesc.GetControllerAndActionAttributes<ControllerGroupAttribute>().First().Useage : "无模块");

                })
                .EnableSwaggerUi(c =>
                {
                    c.DocumentTitle("SntSoft.Web.Api");

                    //汉化js SwaggerCustom
                    c.InjectJavaScript(thisAssembly, "SntSoft.Web.Api.Utlls.Swagger.js.swagger_lang.js");

                    c.DisableValidator();
                });

        }
        /// <summary>
        /// XML路径拼接
        /// </summary>
        /// <param name="name"></param>
        /// <returns></returns>
        protected static string GetXmlCommentsPath(string name)
        {
            return string.Format(@"{0}bin{1}.XML", AppDomain.CurrentDomain.BaseDirectory, name);
        }
    }

第四步：添加汉化js

        //设置控制器注释

第五步：其他特性添加
