Go Radiko

The unofficial radiko.jp APIs Client Library for Go

Installation

• Go 1.7 or newer

$ go get github.com/yyoshiki41/go-radiko

Usage

■ Default

// authentication token is not necessary.
client, err := radiko.New("")
if err != nil {
	panic(err)
}
// Get programs data
stations, err := client.GetNowPrograms(context.Background())
if err != nil {
	log.Fatal(err)
}
fmt.Printf("%v", stations)

■ Get & Set authentication token

• swftools is required.

// 1. Download a swf player.
swfPath := path.Join(dir, "myplayer.swf")
if err := radiko.DownloadPlayer(swfPath); err != nil {
	log.Fatalf("Failed to download swf player. %s", err)
}

// 2. Using swfextract, create an authkey file from a swf player.
cmdPath, err := exec.LookPath("swfextract")
if err != nil {
	log.Fatal(err)
}
authKeyPath := path.Join(dir, "authkey.png")
if c := exec.Command(cmdPath, "-b", "12", swfPath, "-o", authKeyPath); err != c.Run() {
	log.Fatalf("Failed to execute swfextract. %s", err)
}

// 3. Create a new Client.
client, err := radiko.New("")
if err != nil {
	panic(err)
}

// 4. Enables and sets the auth_token.
// After client.AuthorizeToken() has succeeded,
// the client has the enabled auth_token internally.
authToken, err := client.AuthorizeToken(context.Background(), authKeyPath)
if err != nil {
	log.Fatal(err)
}

Premium member (Enable to use the area free.)

Step 1,2 are the same as above.

// 3. Create a new Client.
client, err := radiko.New("")
if err != nil {
	panic(err)
}

// 4. Login as the premium member
// After client.Login() has succeeded,
// the client has the valid cookie internally.
ctx := context.Background()
login, err := client.Login(ctx, "example@mail.com", "example_password")
if err != nil {
    log.Fatal(err)
}
if login.StatusCode() != 200 {                       
    log.Fatalf("Failed to login premium member.\nInvalid status code: %d",
		login.StatusCode())
}

// 5. Enables and sets the auth_token.
// After client.AuthorizeToken() has succeeded,
// the client has the enabled auth_token internally.
authToken, err := client.AuthorizeToken(context.Background(), authKeyPath)
if err != nil {
	log.Fatal(err)
}

■ Use your authentication token

// If the auth_token is cached, set your token in HTTP Header like below.
client, err = radiko.New("auth_token")
if err != nil {
	panic(err)
}
