4.Download iris-swagger by using:
$ go get -u github.com/huntsman-li/iris-swagger
$ go get -u github.com/huntsman-li/iris-swagger/swaggerFiles
And import following in your code:
import "github.com/huntsman-li/iris-swagger" // iris-swagger middleware
import "github.com/huntsman-li/iris-swagger/swaggerFiles" // swagger embed files
package main
import (
"github.com/kataras/iris"
"github.com/huntsman-li/iris-swagger"
"github.com/huntsman-li/iris-swagger/swaggerFiles"
_ "./docs" // docs is generated by Swag CLI, you have to import it.
)
// @title Swagger Example API
// @version 1.0
// @description This is a sample server Petstore server.
// @termsOfService http://swagger.io/terms/
// @contact.name API Support
// @contact.url http://www.swagger.io/support
// @contact.email support@swagger.io

// @host petstore.swagger.io
// @BasePath /v2
func main() {
r := iris.New()
// use iris-swagger middleware to
r.GET("/swagger/*any", swagger.WrapHandler(swaggerFiles.Handler))
r.Run(iris.Addr(":8080"))
}
- Run it, and browser to http://localhost:8080/swagger/index.html, you can see Swagger 2.0 Api documents.
- If you want to disable swagger when some environment variable is set, use
DisablingWrapHandler
package main
import (
"github.com/kataras/iris"
"github.com/huntsman-li/iris-swagger"
"github.com/huntsman-li/iris-swagger/swaggerFiles"
_ "./docs" // docs is generated by Swag CLI, you have to import it.
)
// @title Swagger Example API
// @version 1.0
// @description This is a sample server Petstore server.
// @termsOfService http://swagger.io/terms/
// @contact.name API Support
// @contact.url http://www.swagger.io/support
// @contact.email support@swagger.io
// @license.name Apache 2.0
// @license.url http://www.apache.org/licenses/LICENSE-2.0.html
// @host petstore.swagger.io
// @BasePath /v2
func main() {
r := iris.New()
// use swagger middleware to
r.Get("/swagger/*any", swagger.DisablingWrapHandler(swaggerFiles.Handler, "NAME_OF_ENV_VARIABLE"))
r.Run()
}
Then, if you set envioment variable NAME_OF_ENV_VARIABLE
to anything, /swagger/*any
will respond 404, just like when route unspecified.
