Description

I user router llike this:

session := v2.Group("/sessions")
{
	session.POST("", controllers.Login)
	session.DELETE("/:user_id", controllers.Logout)
	session.POST("/signup", controllers.SignUp)
	session.POST("/forgot_password", controllers.PassBack)
	session.POST("/:user_id/scan", controllers.ScanLogin)
}

but error returns on logs, the methods of sessions/:user_id & sessions/:user_id/scan are deferrent actrauly.

[GIN-debug] POST   /api/v2/sessions          --> app/cmd/http/controllers.Login (4 handlers)
[GIN-debug] DELETE /api/v2/sessions/:user_id --> app/cmd/http/controllers.Logout (4 handlers)
[GIN-debug] POST   /api/v2/sessions/signup   --> app/cmd/http/controllers.SignUp (4 handlers)

panic: wildcard route ':user_id' conflicts with existing children in path '/api/v2/sessions/:user_id/scan'

How can i fix this?? Thank you very much.
