Gin: when use context.Param() to get optional params from url, it will always return a slash

[CodingPapi]

router.GET("api/:fixed/*optional", func(context *gin.Context) {
t1 := context.Param("fixed")
t2 := context.Param("optional")
})

curl http://127.0.0.1:8000/api/user/123

t1 will be "user"
t2 will be "/123"

Is this a bug?
Thank you for any reply

router.GET("api/:fixed/:optional", func(context *gin.Context) {
  t1 := context.Param("fixed")
  t2 := context.Param("optional")
})

change *optional to :optional

@appleboy Thank you for ur reply.
I do know use :optional can get the param value that without a slash, but why there should be a "/" when get an optional param? Is there any way to get optional param without that "/" ? Thank you for your kindness!

:optional is a better way
