Getting nil value for path variables

[kamiiiel]

I would expect to get the path variable but instead I get nil after few times calling the endpoint.
For example if you call this endpoint few times (maybe around 20 times) then you will get nil instead of "25". But for the first few requests it works fine.

package main

import (
"fmt"
"github.com/gramework/gramework"
)

func Hello(ctx *gramework.Context) {
ctx.Writef("Hello %s, id: %s!\n", ctx.UserValue("name"), ctx.UserValue("id"))
}

func main() {
app := gramework.New()
app.GET("/:id/:name", Hello)
app.ListenAndServe(":8080")
}

// Call the endpoint:
curl localhost:8080/25/Bob

I noticed that for the first few time, the path values are not cached so everything is fine but for the rest of the calls, these values are coming from the cache and then id becomes nil.

@EliteGit please look into your gramework.Version

also, we have ctx.Writef, so you don't actually need to use fmt package :)

I'm using version 1.7.0
And it seems the issue is inside this file fasthttprouter_tree.go line 433

if n.hits > 32 {
n.router.cache.PutWild(reqPath, n, tsr, map[string]string{n.path[one:]: path[:end]}, method)
}

Here wrong path variables are saved in the cache
