How to use Swagger UI with go-restful

Get the Swagger UI sources (version 1.2 only)

git clone https://github.com/wordnik/swagger-ui.git

The project contains a "dist" folder. Its contents has all the Swagger UI files you need.

The index.html has an url set to http://petstore.swagger.wordnik.com/api/api-docs. You need to change that to match your WebService JSON endpoint e.g. http://localhost:8080/apidocs.json

Now, you can install the Swagger WebService for serving the Swagger specification in JSON.

config := swagger.Config{
	WebServices:    restful.RegisteredWebServices(),
	ApiPath:        "/apidocs.json",
	SwaggerPath:     "/apidocs/",
	SwaggerFilePath: "/Users/emicklei/Projects/swagger-ui/dist"}
swagger.InstallSwaggerService(config)

Notes

  • Use RouteBuilder.Operation(..) to set the Nickname field of the API spec
  • The WebServices field of swagger.Config can be used to control which service you want to expose and document ; you can have multiple configs and therefore multiple endpoints.
  • Use tag "description" to annotate a struct field with a description to show in the UI
