在golang fasthttp中获取任意请求标头值

Searched through docs and read source, could not find anyway to access something like

ctx.Request.Header.Get("X-Forwarded-For")

I see in header.go, the type RequestHeader struct is defined something like

h     []argsKV
bufKV argsKV

cookies []argsKV

rawHeaders []byte

Is it possible to access these fields without reflection at all?

Found it.

ctx.Request.Header.Peek("X-Forwarded-For")
