Unexpected EOF while trying to send a request from a parsed Raw HTTP request

I'm using golang to parse a raw HTTP request and then send a request to the URL and print the output.

Code:

stra := `GET / HTTP/1.1
Host: google.com
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.61 Safari/537.36
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9
Accept-Encoding: gzip, deflate
Accept-Language: en-US,en;q=0.9
Connection: close`
	r, err := http.ReadRequest(bufio.NewReader(strings.NewReader(stra)))
	if err != nil {
		fmt.Println(err.Error())
		os.Exit(1)
	}
	u, err := url.Parse("https://" + r.Host + r.URL.String())
	if err != nil {
		panic(err)
	}
	req.URL = u
	transport := http.Transport{}
	transport.TLSClientConfig = &tls.Config{InsecureSkipVerify: true}
	client := &http.Client{Transport: &transport}
	resp, err := client.Do(req)

Error:

unexpected EOF

Kindly help.

http header must ends with \r\n\r\n, but it seems that \n is ok for http.ReadRequest? the code below really works.

package main

import (
	"bufio"
	"fmt"
	"net/http"
	"os"
	"strings"
)

func main() {
	stra := `GET / HTTP/1.1
Host: google.com

`
	req, err := http.ReadRequest(bufio.NewReader(strings.NewReader(stra)))
	if err != nil {
		fmt.Println(err.Error())
		os.Exit(1)
	}
	fmt.Println(req)
}
