I'd like to parse the response of a web request, but I'm getting trouble accessing it as string.
func main() {
resp, err := http.Get("http://google.hu/")
if err != nil {
// handle error
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
ioutil.WriteFile("dump", body, 0600)
for i:= 0; i < len(body); i++ {
fmt.Println( body[i] ) // This logs uint8 and prints numbers
}
fmt.Println( reflect.TypeOf(body) )
fmt.Println("done")
}
How can I access the response as string? ioutil.WriteFile
writes correctly the response to a file.
I've already checked the package reference but it's not really helpful.

The method you're using to read the http body response returns a byte slice:
func ReadAll(r io.Reader) ([]byte, error)
You can convert []byte
to a string by using
body, err := ioutil.ReadAll(resp.Body)
bodyString := string(body)
string(byteslice) will convert byte slice to string, just know that it's not only simply type conversion, but also memory copy.
