Path conflict issue

[sreejithag]

Description

I need two paths in one of my project

/:token
/:customPath/:token

i understand the issues with the http router
is their any any workaround to fix this issue other than adding a wild card pattern and match with interceptor

How to reproduce

package main

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

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

	r.GET("/:custom/:token", func(c *gin.Context) {
		custom := c.Param("custom")
		token := c.Param("token")
		c.JSON(200, gin.H{
			"message": "Specific route",
			"custom":  custom,
			"token":   token,
		})
	})

	r.GET("/:token", func(c *gin.Context) {
		token := c.Param("token")
		c.JSON(200, gin.H{
			"message": "General route",
			"token":   token,
		})
	})

	r.Run(":8080") // Start the server on port 8080
}

Expectations

panic: ':token' in new path '/:token' conflicts with existing wildcard ':custom' in existing prefix '/:custom'

Environment

• go version: 1.23.4
• gin version (or commit ref): 1.10.0
• operating system: macOS 15.2

Hello @sreejithag, depending on your project's semantics, you could use a static prefix to work around this issue:

Example 1
Add a static /general/ prefix to mark the general route.

r.GET("/general/:token", ...)
r.GET("/:custom/:token", ...)

Example 2
Make the route for customs explicit by adding a static /customs/ prefix.

r.GET("/customs/:custom/:token", ...)
r.GET("/:token", ...)
