Catch-all route has multiple catch-all in another way

[authhwang]

Description

After seeing all of related issues and source code, i know it is illegal that a path has multiple catch-all node. so

In way a:

r.GET("/cmd/:user/*info/*action", func(c *gin.Context) {
		fmt.Println("enter /cmd/:user/*info/*action")
})

Result:

It will throw a error saying "catch-all routes are only allowed at the end of the path in path '/cmd/:user/*info/*action'".

In way b:

r.GET("/cmd/:user/*info", func(c *gin.Context) {
		fmt.Println("enter /cmd/:name/*info")
})

r.GET("/cmd/:user/*info/*action", func(c *gin.Context) {
                fmt.Println("enter /cmd/:user/*info/*action")
})

Reuslt:

It work successfully.

How to reproduce

package main

import (
	"github.com/gin-gonic/gin"
)

func main() {
	r := gin.Default()

	r.GET("/cmd/:user/*info", func(c *gin.Context) {
               fmt.Println("enter /cmd/:name/*info")
	})

	r.GET("/cmd/:user/*info/*action", func(c *gin.Context) {
		fmt.Println("enter /cmd/:name/*info/*action")
	})

	r.GET("/cmd/:user/*info/*action/*test", func(c *gin.Context) {
		fmt.Println("enter /cmd/:name/*info/*action/*test")
	})
	
	r.Run(":8080")
}

Expectations

get a error in terminal like way a.

Actual result

[GIN-debug] GET    /cmd/:user/*info          --> main.main.func1 (3 handlers)
[GIN-debug] GET    /cmd/:user/*info/*action  --> main.main.func2 (3 handlers)
[GIN-debug] GET    /cmd/:user/*info/*action/*test --> main.main.func3 (3 handlers)
[GIN-debug] Listening and serving HTTP on :8080

run successfully with gin.

Environment

• go version: go1.13.4
• gin version (or commit ref): v1.5.0
• operating system: windows/amd64

[authhwang]

please use newer code, i forget to import fmt package. sorry.

package main

import (
        "fmt"
	"github.com/gin-gonic/gin"
)

func main() {
	r := gin.Default()

	r.GET("/cmd/:user/*info", func(c *gin.Context) {
               fmt.Println("enter /cmd/:name/*info")
	})

	r.GET("/cmd/:user/*info/*action", func(c *gin.Context) {
		fmt.Println("enter /cmd/:name/*info/*action")
	})

	r.GET("/cmd/:user/*info/*action/*test", func(c *gin.Context) {
		fmt.Println("enter /cmd/:name/*info/*action/*test")
	})
	
	r.Run(":8080")
}
