Package Usage

package provides itunes-search-api wrapper of Golang. with extra support for applications. If you are using PostgreSQL as well, it's very convient to save app data to PG.

import

import . "github.com/Vonng/go-itunes-search"

Search Example

search with keyword Hello & World，US AppStore，Restrict media type to Software，At more 5 result.

func TestSearch(t *testing.T) {
	res, _ := Search([]string{"Hello", "World"}).
		Country(US).
		App().
		Limit(5).
		Results()

	for _, r := range res {
		r.Print()
	}
}

result is fetched via .Results or .Result，the latter assert only one result is returned so it returns *Entry rather than []Entry。

Lookup Example

if you know something could used to identify a track, then lookup API may be a better approach. Instead of specifying term, you need something like iTunesID (track_id), BundleID(app only), AMG ID, etc…。And when using lookup API, there could only be one or zero entry being returned. So the API chain may end with Result rather than Results

Here's how it works, these lookups may return same results:

Lookup().ID(414478124).Country(CN).Result()
Lookup().BundleID("com.tencent.xin").Result()
Lookup().Set(BundleID, "com.tencent.xin").Result()

Other examle

other small examples

SearchOne("世界").Country(CN).Entities([]string{Movie,Music}).Results()
SearchOne("Love").Media(Music).Entity(MusicArtist).Limit(5).Results()
Lookup().ID(529479190).Result()
Lookup().Country(GB).ID(529479190).Result()
Lookup().BundleID("com.supercell.magic").Result()

check api_test.go for more details & examples.

Entry

Entry is naive mapping to iTunes's response structure. iTunes orgnaize everything just like music track.

type Entry struct {
	TrackID                            int64    `json:"trackId"` // Track

App

for those user who only interested in Application rather than music. github.com/Vonng/go-itunes-search/app provides a more precise representation of iOS application: App.

App is an enhanced version of Entity.

It provides some additinoal features:

• more friendly & shorter field names.
• fetch extra fields like InAppPurchase,Reviews,RelatedApps,SupportedSites, etc...
• Parser to fetch extra fields from corresponding country's store.
• ORM Mapping to PostgreSQL table defined in app/app.ddl , can be used by go-pg
• Pretty print template

While it introduce two more dependency: goquery for parsing iTunes Page, go-pg for Save function.

type App struct {
	ID               int64  `sql:",pk"`
	Name             string
	URL              string
