Golang : Get YouTube playlist



Tags : golang youtube playlist

A programmer productivity can be increased with a good playlist of music to get into the "zone" and I need this while coding out the job board for socketloop.com(1)

Just for fun, this is the Golang code to download a playlist from YouTube, unmarshal the XML data and display the content.

 package main

 import (
 "encoding/xml"
 "fmt"
 "io/ioutil"
 "net/http"
 "os"
 "strings"
 )

 type YouTubeEntries struct {
 XMLName xml.Name `xml:"entry"`
 ID string `xml:"id"`
 Published string `xml:"published"`
 Updated string `xml:"updated"`
 Category  string `xml:"category"`
 Title string `xml:"title"`
 Content string `xml:"content"`
 Link string `xml:"link"`
 Author string `xml:"author"`
 }

 type YouTubeFeeds struct {
 XMLName xml.Name `xml:"feed"`
 YouTubeEntries []YouTubeEntries `xml:"entry"`
 }

 // modify here to add more data to be displayed
 func (data YouTubeEntries) String() string {
 dateToYMD := strings.Split(data.Published, "T")
 return fmt.Sprintf("\t%s - %s - [%s]\n", dateToYMD[0], data.Title, data.ID)
 }

 func main() {
 response, err := http.Get("http://gdata.youtube.com/feeds/api/playlists/RDXIzDDYrS4iE?v=2")

 if err != nil {
 fmt.Println(err)
 os.Exit(1)
 }

 defer response.Body.Close()

 XMLdata, err := ioutil.ReadAll(response.Body)

 if err != nil {
 fmt.Println(err)
 os.Exit(1)
 }

 var youtubeFeeds YouTubeFeeds

 xml.Unmarshal(XMLdata, &youtubeFeeds)
 fmt.Println(youtubeFeeds.YouTubeEntries)

 // alternate ways to display the list
 for k, v := range youtubeFeeds.YouTubeEntries {
 fmt.Printf("\t%d - [%s]\n", k, v)
 }
 }

Have fun learning Go and YouTube API !


1 - it is still a work in progress and I will announce it soon
