asp.net mvc api swagger 配置

1、安装插件 Swashbuckle（版本5.6.0） 和 Swagger.Net.UI（版本1.1.0）

2、SwaggerNet类中注释掉一下代码：

using System;
using System.IO;
using System.Web;
using System.Web.Http;
using System.Web.Http.Description;
using System.Web.Http.Dispatcher;
using System.Web.Routing;
using Swagger.Net;

//[assembly: WebActivator.PreApplicationStartMethod(typeof(ZXIT.YDJW.WebServer.App_Start.SwaggerNet), "PreStart")]
//[assembly: WebActivator.PostApplicationStartMethod(typeof(ZXIT.YDJW.WebServer.App_Start.SwaggerNet), "PostStart")]
namespace ZXIT.YDJW.WebServer.App_Start
{
    public static class SwaggerNet
    {
        public static void PreStart()
        {
            RouteTable.Routes.MapHttpRoute(
                name: "SwaggerApi",
                routeTemplate: "api/docs/{controller}",
                defaults: new { swagger = true }
            );
        }

        public static void PostStart()
        {
            var config = GlobalConfiguration.Configuration;

            config.Filters.Add(new SwaggerActionFilter());

            try
            {
                config.Services.Replace(typeof(IDocumentationProvider),
                    new XmlCommentDocumentationProvider(HttpContext.Current.Server.MapPath("~/bin/ZXIT.YDJW.WebServer.XML")));
            }
            catch (FileNotFoundException)
            {
                throw new Exception("Please enable \"XML documentation file\" in project properties with default (bin\\ZXIT.YDJW.WebServer.XML) value or edit value in App_Start\\SwaggerNet.cs");
            }
        }
    }
}

3、SwaggerConfig 类中配置一下内容

using System.Web.Http;
using WebActivatorEx;
using ZXIT.YDJW.WebServer;
using Swashbuckle.Application;

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

namespace ZXIT.YDJW.WebServer
{
    public class SwaggerConfig
    {
        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.
                        //
                        c.SingleApiVersion("v1", "ZXIT.YDJW.WebServer");
                        //添加XML解析
                        c.IncludeXmlComments(GetXmlCommentsPath());

                        // If you want the output Swagger docs to be indented properly, enable the "PrettyPrint" option.
                        //
                        //c.PrettyPrint();

                        // If your API has multiple versions, use "MultipleApiVersions" instead of "SingleApiVersion".
                        // In this case, you must provide a lambda that tells Swashbuckle which actions should be
                        // included in the docs for a given API version. Like "SingleApiVersion", each call to "Version"
                        // returns an "Info" builder so you can provide additional metadata per API version.
                        //
                        //c.MultipleApiVersions(
                        //    (apiDesc, targetApiVersion) => ResolveVersionSupportByRouteConstraint(apiDesc, targetApiVersion),
                        //    (vc) =>
                        //    {
                        //        vc.Version("v2", "Swashbuckle Dummy API V2");
                        //        vc.Version("v1", "Swashbuckle Dummy API V1");
                        //    });

                        // You can use "BasicAuth", "ApiKey" or "OAuth2" options to describe security schemes for the API.
                        // See https://github.com/swagger-api/swagger-spec/blob/master/versions/2.0.md for more details.
                        // NOTE: These only define the schemes and need to be coupled with a corresponding "security" property
                        // at the document or operation level to indicate which schemes are required for an operation. To do this,
                        // you'll need to implement a custom IDocumentFilter and/or IOperationFilter to set these properties
                        // according to your specific authorization implementation
                        //
                        //c.BasicAuth("basic")
                        //    .Description("Basic HTTP Authentication");
                        //
                        // NOTE: You must also configure 'EnableApiKeySupport' below in the SwaggerUI section
                        //c.ApiKey("apiKey")
                        //    .Description("API Key Authentication")
                        //    .Name("apiKey")
                        //    .In("header");
                        //
                        //c.OAuth2("oauth2")
                        //    .Description("OAuth2 Implicit Grant")
                        //    .Flow("implicit")
                        //    .AuthorizationUrl("http://petstore.swagger.wordnik.com/api/oauth/dialog")
                        //    //.TokenUrl("https://tempuri.org/token")
                        //    .Scopes(scopes =>
                        //    {
                        //        scopes.Add("read", "Read access to protected resources");
                        //        scopes.Add("write", "Write access to protected resources");
                        //    });

                        // Set this flag to omit descriptions for any actions decorated with the Obsolete attribute
                        //c.IgnoreObsoleteActions();

                        // Each operation be assigned one or more tags which are then used by consumers for various reasons.
                        // For example, the swagger-ui groups operations according to the first tag of each operation.
                        // By default, this will be controller name but you can use the "GroupActionsBy" option to
                        // override with any value.
                        //
                        //c.GroupActionsBy(apiDesc => apiDesc.HttpMethod.ToString());

                        // You can also specify a custom sort order for groups (as defined by "GroupActionsBy") to dictate
                        // the order in which operations are listed. For example, if the default grouping is in place
                        // (controller name) and you specify a descending alphabetic sort order, then actions from a
                        // ProductsController will be listed before those from a CustomersController. This is typically
                        // used to customize the order of groupings in the swagger-ui.
                        //
                        //c.OrderActionGroupsBy(new DescendingAlphabeticComparer());

                        // If you annotate Controllers and API Types with
                        // Xml comments (http://msdn.microsoft.com/en-us/library/b2s063f7(v=vs.110).aspx), you can incorporate
                        // those comments into the generated docs and UI. You can enable this by providing the path to one or
                        // more Xml comment files.
                        //
                        //c.IncludeXmlComments(GetXmlCommentsPath());

                        // Swashbuckle makes a best attempt at generating Swagger compliant JSON schemas for the various types
                        // exposed in your API. However, there may be occasions when more control of the output is needed.
                        // This is supported through the "MapType" and "SchemaFilter" options:
                        //
                        // Use the "MapType" option to override the Schema generation for a specific type.
                        // It should be noted that the resulting Schema will be placed "inline" for any applicable Operations.
                        // While Swagger 2.0 supports inline definitions for "all" Schema types, the swagger-ui tool does not.
                        // It expects "complex" Schemas to be defined separately and referenced. For this reason, you should only
                        // use the "MapType" option when the resulting Schema is a primitive or array type. If you need to alter a
                        // complex Schema, use a Schema filter.
                        //
                        //c.MapType<ProductType>(() => new Schema { type = "integer", format = "int32" });

                        // If you want to post-modify "complex" Schemas once they've been generated, across the board or for a
                        // specific type, you can wire up one or more Schema filters.
                        //
                        //c.SchemaFilter<ApplySchemaVendorExtensions>();

                        // In a Swagger 2.0 document, complex types are typically declared globally and referenced by unique
                        // Schema Id. By default, Swashbuckle does NOT use the full type name in Schema Ids. In most cases, this
                        // works well because it prevents the "implementation detail" of type namespaces from leaking into your
                        // Swagger docs and UI. However, if you have multiple types in your API with the same class name, you'll
                        // need to opt out of this behavior to avoid Schema Id conflicts.
                        //
                        //c.UseFullTypeNameInSchemaIds();

                        // Alternatively, you can provide your own custom strategy for inferring SchemaId's for
                        // describing "complex" types in your API.
                        //
                        //c.SchemaId(t => t.FullName.Contains('`') ? t.FullName.Substring(0, t.FullName.IndexOf('`')) : t.FullName);

                        // Set this flag to omit schema property descriptions for any type properties decorated with the
                        // Obsolete attribute
                        //c.IgnoreObsoleteProperties();

                        // In accordance with the built in JsonSerializer, Swashbuckle will, by default, describe enums as integers.
                        // You can change the serializer behavior by configuring the StringToEnumConverter globally or for a given
                        // enum type. Swashbuckle will honor this change out-of-the-box. However, if you use a different
                        // approach to serialize enums as strings, you can also force Swashbuckle to describe them as strings.
                        //
                        //c.DescribeAllEnumsAsStrings();

                        // Similar to Schema filters, Swashbuckle also supports Operation and Document filters:
                        //
                        // Post-modify Operation descriptions once they've been generated by wiring up one or more
                        // Operation filters.
                        //
                        //c.OperationFilter<AddDefaultResponse>();
                        //
                        // If you've defined an OAuth2 flow as described above, you could use a custom filter
                        // to inspect some attribute on each action and infer which (if any) OAuth2 scopes are required
                        // to execute the operation
                        //
                        //c.OperationFilter<AssignOAuth2SecurityRequirements>();

                        // Post-modify the entire Swagger document by wiring up one or more Document filters.
                        // This gives full control to modify the final SwaggerDocument. You should have a good understanding of
                        // the Swagger 2.0 spec. - https://github.com/swagger-api/swagger-spec/blob/master/versions/2.0.md
                        // before using this option.
                        //
                        //c.DocumentFilter<ApplyDocumentVendorExtensions>();

                        // In contrast to WebApi, Swagger 2.0 does not include the query string component when mapping a URL
                        // to an action. As a result, Swashbuckle will raise an exception if it encounters multiple actions
                        // with the same path (sans query string) and HTTP method. You can workaround this by providing a
                        // custom strategy to pick a winner or merge the descriptions for the purposes of the Swagger docs
                        //
