Saya mencoba membaca data JSON dari web, tetapi kode itu mengembalikan hasil yang kosong. Saya tidak yakin apa yang saya lakukan salah di sini.
package main
import "os"
import "fmt"
import "net/http"
import "io/ioutil"
import "encoding/json"
type Tracks struct {
Toptracks []Toptracks_info
}
type Toptracks_info struct {
Track []Track_info
Attr []Attr_info
}
type Track_info struct {
Name string
Duration string
Listeners string
Mbid string
Url string
Streamable []Streamable_info
Artist []Artist_info
Attr []Track_attr_info
}
type Attr_info struct {
Country string
Page string
PerPage string
TotalPages string
Total string
}
type Streamable_info struct {
Text string
Fulltrack string
}
type Artist_info struct {
Name string
Mbid string
Url string
}
type Track_attr_info struct {
Rank string
}
func get_content() {
// json data
url := "http://ws.audioscrobbler.com/2.0/?method=geo.gettoptracks&api_key=c1572082105bd40d247836b5c1819623&format=json&country=Netherlands"
res, err := http.Get(url)
if err != nil {
panic(err.Error())
}
body, err := ioutil.ReadAll(res.Body)
if err != nil {
panic(err.Error())
}
var data Tracks
json.Unmarshal(body, &data)
fmt.Printf("Results: %v\n", data)
os.Exit(0)
}
func main() {
get_content()
}
type WebKeys struct { Keys []struct { X5t string X5c []string } }
bahkan ketika params sebenarnya di JSON yang Anda parsing berada dalam huruf kecil. Contoh JSON:{ "keys": [{ "x5t": "foo", "x5c": "baaaar" }] }
