why ctx.Request.URI().RequestURI() is missing?

[59duncom]

I had write a websocket proxy,but ctx.requesturi is miss and fmt.Println( ctx.Request.String()) is ok:

func Proxyhttp(ctx *fasthttp.RequestCtx){

fmt.Println( string(ctx.RequestURI())) //here is ok
if websocket.FastHTTPIsWebSocketUpgrade(ctx){
Dowebsocket(ctx, clientproxy.source)

}
}
func Dowebsocket( ctx *fasthttp.RequestCtx,sourcestr string){
upgrader := websocket.FastHTTPUpgrader{HandshakeTimeout: 15 * time.Second, CheckOrigin:func(ctx *fasthttp.RequestCtx) bool { return true }, }
upgrader.Upgrade(ctx,func(ws *websocket.Conn) {
wsURL := url.URL{Scheme: "ws", Host: sourcestr, Path:string(ctx.RequestURI())) }//here is miss
fmt.Println(string(ctx.URI().RequestURI())) //here is miss
dialer := websocket.Dialer{
Proxy: http.ProxyFromEnvironment,
HandshakeTimeout: 15 * time.Second,
}
server, _, err := dialer.Dial(wsURL.String(), nil)
...................
}

first ctx.RequestURI() is "/echo" ,missing is print "/"

Maybe there is any problem before you print the request URI.
As I checked by making a simple program which prints the ctx.URI().RequestURI() it should work. So I think maybe the websocket library is modifying the request uri or something else. Not a fasthttp issue

I had use "github.com/fasthttp/websocket"for websocket
I will write a demo and test

Ah, yep, I know where the error is. https://github.com/valyala/fasthttp/blob/master/server.go#L2063
The RequestCtx is reset when a connection is Hijacked.
