| # Line Usage | ||
|
|
||
| Install notifier using: | ||
|
|
||
| * `go get -u github.com/nikoksr/notify` | ||
|
|
||
|
|
||
| ## Sample Code | ||
|
|
||
| ```go | ||
| package main | ||
|
|
||
| import ( | ||
| "github.com/nikoksr/notify" | ||
| "github.com/nikoksr/notify/service/line" | ||
| "golang.org/x/net/context" | ||
| ) | ||
|
|
||
| func main() { | ||
| // Assuming you already have a line messaging API credential | ||
| // Provide your channel secret and access token | ||
| lineService, _ := line.New("channelSecret", "channelAccessToken") | ||
|
|
||
| // Add id from various receivers | ||
| // You can try to use your own line id for testing | ||
| lineService.AddReceivers("userID1", "groupID1") | ||
|
|
||
| notifier := notify.New() | ||
|
|
||
| // Tell our notifier to use the line service. You can repeat the above process | ||
| // for as many services as you like and just tell the notifier to use them. | ||
| notifier.UseServices(lineService) | ||
|
|
||
| // Send a message | ||
| err := notifier.Send( | ||
| context.Background(), | ||
| "Welcome", | ||
| "I am a bot written in Go!", | ||
| ) | ||
|
|
||
| if err != nil { | ||
| panic(err) | ||
| } | ||
