I'm trying to parse the XML response from an API, and when call fmt.Println
and pass the response body, I get a weird string:
&{0xc8200e6140 {0 0} false <nil> 0xc2030 0xc1fd0}
I've confirmed that I can curl
the API and get XML as expected. (I also get the same response sending a GET
request with the Postman Chrome extension.) Is this an encoding issue?
Here's the relevant code:
type Album struct {
Title string `xml:"album>name"`
Artist string `xml:"album>artist>name"`
PlayCount uint64 `xml:"album>playcount"`
}
const lastFMAPIKey string = "<My api key>"
const APIURL string = "http://ws.audioscrobbler.com/2.0/"
func perror(err error) {
if err != nil {
panic(err)
}
}
func getListeningInfo(url string) []byte {
resp, err := http.Get(url)
perror(err)
defer resp.Body.Close()
// this is the line that prints the string above
fmt.Println(resp.Body)
body, err2 := ioutil.ReadAll(resp.Body)
perror(err2)
return body
}
func main() {
url := APIURL + "?method=user.getTopAlbums&user=iamnicholascox&period=1month&limit=1&api_key=" + lastFMAPIKey
album := Album{}
err := xml.Unmarshal(getListeningInfo(url), &album)
perror(err)
fmt.Printf(album.Artist)
}
For reference, printing out resp
instead of just resp.Body
gives this:
