What did you do?

im trying to understand, what the difference?
im do a request in python

import requests

url = "http://159.223.250.48/bonus/promo"
data = {"body": {"code": "wolu24c"}}
headers = {
    "Host": "lb-api-rt.com",
    "Content-Type": "application/json",
    "Accept": "application/json",
    "SessionId": "sqeh0fo8c4iju00p6tii6nnnq3",
}
response = requests.post(url, json=data, headers=headers)
print(response.status_code, response.text)

and python request working well as exected
the output

400 {"code":1,"message":"The promo code \u0022wolu24c\u0022 has already been taken once","i18n":"api.bonus.promo.already_taken","args":{"@code":"wolu24c","@player_id":"5552822"}}

then i do golang code:

package main

import (
	"bytes"
	"fmt"
	"io/ioutil"
	"log"
	"net/http"
)

func main() {
	url := "http://159.223.250.48/bonus/promo"

	var jsonStr = []byte(`{"body":{"code": "wolu24c"}}`)
	req, err := http.NewRequest("POST", url, bytes.NewBuffer(jsonStr))
	if err != nil {
		fmt.Println("Error creating request:", err)
		return
	}

	// Set headers
	req.Header.Set("Host", "lb-api-rt.com")
	req.Header.Set("Content-Type", "application/json")
	req.Header.Set("Accept", "application/json")
	req.Header.Set("SessionId", "sqeh0fo8c4iju00p6tii6nnnq3")

	// Create an HTTP client and send the request
	client := http.Client{}
	resp, err := client.Do(req)
	if err != nil {
		fmt.Println("Error sending request:", err)
		return
	}
	defer resp.Body.Close()

	// Print the response status and body
	fmt.Println("Status code:", resp.StatusCode)

	b, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		log.Println(err)
	}
	log.Println(string(b))

}

and i got the response:

Status code: 404
2024/08/26 22:54:51 <html>
<head><title>404 Not Found</title></head>
<body>
<center><h1>404 Not Found</h1></center>
<hr><center>nginx/1.18.0</center>
</body>
</html>

i trying to debug it and spend to much to to understand what the difference and after hours i understand that the problem is in:
this line

req.Header.Set("Host", "lb-api-rt.com")

when i change this line to:

req.Host = "lb-api-rt.com"

The request works as expected...
Why default http package have a different behaviours in this lines?
req.Header.Set("Host", "lb-api-rt.com")
req.Host = "lb-api-rt.com"

What did you see happen?

Status code: 404
2024/08/26 22:54:51

<title>404 Not Found</title>

404 Not Found

nginx/1.18.0

What did you expect to see?

{"code":1,"message":"The promo code \u0022wolu24c\u0022 has already been taken once","i18n":"api.bonus.promo.already_taken","args":{"@code":"wolu24c","@player_id":"5552822"}}

Unlike many projects Go does not use the issue tracker for questions. Please see https://go.dev/wiki/Questions. Thanks.

For the difference between setting the Host header and the Host field please see https://pkg.go.dev/net/http#Request.Host.

when i set

req.Header.Set("Host", "lb-api-rt.com")

I expect that the host value will be the some (correct value)
becouse i set this value! but under the hood the Header.Set change this value to

Request Dump:
POST /bonus/promo HTTP/1.1
Host: 159.223.250.48
User-Agent: python-requests/2.28.2
Content-Length: 29
Accept: application/json
Accept-Encoding: gzip, deflate
Connection: keep-alive
Content-Type: application/json
Sessionid: sqeh0fo8c4iju00p6tii6nnnq3

so its not expected behovior
the value must be the some as i set

was debug with

requestDump, err := httputil.DumpRequestOut(req, true)
	if err != nil {
		fmt.Println("Error dumping request:", err)
	}
	fmt.Println("Request Dump:\n", string(requestDump))
