建立Web API工程
選Empty,勾選Web API,不要選擇Web API,那樣會把MVC勾上,這裡不需要MVC
Web API工程屬性
XML檔案用于生成線上文檔
建立Windows服務作為Web API的宿主
WebApiHost工程屬性控制台應用程式友善調試
Windows服務安裝Microsoft.AspNet.WebApi.OwinSelfHost
工程WebApiDemo需要引用Microsoft.Owin.dll
WebApiDemo安裝Swashbuckle

接口實作
1、繼承ApiController
2、RoutePrefix設定路由字首
3、SwaggerResponse用于生成線上文檔描述

// In this case, you must provide a lambda that tells Swashbuckle which actions should be

// 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

// 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
//
//c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());
// Wrap the default SwaggerGenerator with additional behavior (e.g. caching) or provide an
// alternative implementation for ISwaggerProvider with the CustomProvider option.
//
//c.CustomProvider((defaultProvider) => new CachingSwaggerProvider(defaultProvider));

// By default, swagger-ui will validate specs against swagger.io's online validator and display the result

//c.SetValidatorUrl("http://localhost/validator");
//c.DisableValidator();
// Use this option to control how the Operation listing is displayed.
// It can be set to "None" (default), "List" (shows operations for each resource),

//c.DocExpansion(DocExpansion.List);

// it for all operations.
//
//c.SupportedSubmitMethods("GET", "HEAD");
// Use the CustomAsset option to provide your own version of assets used in the swagger-ui.
// It's typically used to instruct Swashbuckle to return your version instead of the default
// when a request is made for "index.html". As with all custom content, the file must be included
// in your project as an "Embedded Resource", and then the resource's "Logical Name" is passed to
// the method as shown below.

//c.CustomAsset("index", containingAssembly, "YourWebApiProject.SwaggerExtensions.index.html");
// If your API has multiple versions and you've applied the MultipleApiVersions setting
// as described above, you can also enable a select box in the swagger-ui, that displays
// a discovery URL for each version. This provides a convenient way for users to browse documentation

//
//c.EnableDiscoveryUrlSelector();
// If your API supports the OAuth2 Implicit flow, and you've described it correctly, according to

// clientSecret: null,
// realm: "test-realm",
// appName: "Swagger UI"
// //additionalQueryStringParams: new Dictionary<string, string>() { { "foo", "bar" } }

// If your API supports ApiKey, you can override the default values.
// "apiKeyIn" can either be "query" or "header"
