Example with Gin

[dingdayu]

If you are using Gin, I hope the following content can help you:

router = gin.New()
router.GET("/debug/statsviz/*filepath", func(context *gin.Context) {
	if context.Param("filepath") == "/ws" {
		statsviz.Ws(context.Writer, context.Request)
		return
	}
	statsviz.IndexAtRoot("/debug/statsviz").ServeHTTP(context.Writer, context.Request)
})
router.Run(":8080")

Failed example

Fail one: "Not Found."

router = gin.New()
router.GET("/debug/statsviz/ws", gin.WrapF(statsviz.Ws))
router.GET("/debug/statsviz/",  gin.WrapH(statsviz.Index))
router.Run(":8080")

Because /debug/statsviz/ is a static directory, Need to register with router.StaticFS("/more_static", http.Dir("my_file_system"))

gin#serving-static-files

Fail two: "wildcard route conflicts with existing children"

router = gin.New()
router.GET("/debug/statsviz/ws", gin.WrapF(statsviz.Ws))
router.GET("/debug/statsviz/*filepath",  gin.WrapH(statsviz.Index))
router.Run(":8080")

panic: '/ws' in new path '/debug/statsviz/ws' conflicts with existing wildcard '/*filepath' in existing prefix '/debug/statsviz/*filepath'

Good debugging tool, hope to help more people.
