Why 404

when GET /universe/api/v1/im/unilog/ima/ads and /universe/api/v1/im/unilog/iam/ads.

Description

How to reproduce

package main

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

func main() {
    gin.SetMode(gin.DebugMode)
    engine := gin.Default()
    f := func(ctx *gin.Context) {
        ctx.JSON(200, "halo: "+ctx.Request.URL.Path)
    }
    engine.GET("/universe/api/v1/im/unilog/:app/*a", f)
    engine.POST("/universe/api/v1/im/unilog/:app/*a", f)
    engine.GET("/universe/api/v1/im/unilog/im/", f)
    engine.Run(":8989")
}

func main() {
    gin.SetMode(gin.DebugMode)
    engine := gin.Default()
    f1 := func(ctx *gin.Context) {
        ctx.JSON(200, "/:app/*a"+ctx.Request.URL.Path)
    }
    f2 := func(ctx *gin.Context) {
        ctx.JSON(200, "/helloworld"+ctx.Request.URL.Path)
    }

    engine.GET("/:app/*a", f1) 
    engine.GET("/helloworld", f2)
    engine.Run(":8989")
}
// all the request path like /*/* will execute f1 except that the path begin with `h`,   
// e.g  /haha/hi   /hello/liushihao /hi/world

Is it a bug? Or why just match only the first letter h ?

Path /helloworld will only match /helloworld, so any path like // will match /:app/*a

Path /helloworld will only match /helloworld, so any path like // will match /:app/*a

I can not aggree with you. When the Path /helloworld router exists, any path like /h/ will not match /:app/*a

Can you test it on v1.7.7?
