I want to make an empty post request to telegram. The problem is if i close multipart once, it hangs forever:
func main() {
var requestBody bytes.Buffer
multiPartWriter := multipart.NewWriter(&requestBody)
multiPartWriter.Close() // closing once
req, _ := http.NewRequest("POST", "https://api.telegram.org/bot<telegram token>/getme", &requestBody)
req.Header.Set("Content-Type", multiPartWriter.FormDataContentType())
client := &http.Client{}
client.Do(req)
}
But if i close the multipart twice it works. Can anyone explain why this happens?

I just checked the Telegram API.
I guess the general problem is, that you use a buffer that is not initialized. You don't need the buffer, you don't need any payload in the request. You can just pass nil as request data. Like this:
func main() {
req, err := http.NewRequest("POST", "https://api.telegram.org/bot<token>/getme", nil)
if err != nil {
panic(err)
}
client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
panic(err)
}
result, err := ioutil.ReadAll(resp.Body)
if err != nil {
panic(err)
}
println(string(result))
}
