WebApi+Swagger多版本控制
在写webapi接口时经常会有多个版本的需求，前端用swagger来做在线测试是很好的选择，但对于有多个版本的话，swagger的显示经常会是个问题，在查阅不少资料后自己实现了，webapi多版本统一显示，统一调用入口；和分版本显示。各有各的优点，统一显示的话可以统一查阅；分版本的话，对查找实现版本比较轻松。
统一显示：

// 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
// 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
// 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
//
// 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
// 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.
// 打开swagger文档过滤
c.DocumentFilter
// 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.FirstOrDefault());
// Wrap the default SwaggerGenerator with additional behavior (e.g. caching) or provide an
// alternative implementation for ISwaggerProvider with the CustomProvider option.
