func main() {
	client := req.C().DevMode().
		SetProxyURL("socks5://127.0.0.1:10808").
		WrapRoundTripFunc(func(rt req.RoundTripper) req.RoundTripFunc {
			return func(req *req.Request) (resp *req.Response, err error) {
				req.URL.Host = "httpbin.org"
				return rt.RoundTrip(req)
			}
		})
	client.R().MustGet("https://54.237.103.220/ip")
}
