Authentication sample

Generate the code with a security principal:

swagger generate server -A AuthSample -P models.Principal -f ./swagger.yml

Edit the ./restapi/configure_auth_sample.go file

func configureAPI(api *operations.AuthSampleAPI) http.Handler {
	// configure the api here
	api.ServeError = errors.ServeError

	// Set your custom logger if needed. Default one is log.Printf
	// Expected interface func(string, ...interface{})
	//
	// Example:
	api.Logger = log.Printf

	api.JSONConsumer = runtime.JSONConsumer()

	api.JSONProducer = runtime.JSONProducer()

	// Applies when the "x-token" header is set
	api.KeyAuth = func(token string) (*models.Principal, error) {
		if token == "abcdefuvwxyz" {
			prin := models.Principal(token)
			return &prin, nil
		}
		api.Logger("Access attempt with incorrect api key auth: %s", token)
		return nil, errors.New(401, "incorrect api key auth")
	}

	api.CustomersCreateHandler = customers.CreateHandlerFunc(func(params customers.CreateParams, principal *models.Principal) middleware.Responder {
		return middleware.NotImplemented("operation customers.Create has not yet been implemented")
	})
	api.CustomersGetIDHandler = customers.GetIDHandlerFunc(func(params customers.GetIDParams, principal *models.Principal) middleware.Responder {
		return middleware.NotImplemented("operation customers.GetID has not yet been implemented")
	})

	api.ServerShutdown = func() {}

	return setupGlobalMiddleware(api.Serve(setupMiddlewares))
}

Run the server:

go run ./cmd/auth-sample-server/main.go --port 35307
