pushnotification
Package pushnotification
sends push notification via Amazon SNS based on the device token.
Provide the type of the device and optional the EndpointArn. The EndpointArn will be created on the fly if needed. This can be stored afterwards for future use.
Device types ios
, android
and windows
are supported by default, for other platforms you need to provide the device type.
If APNSSandbox
is provided and the type is ios
, a pushnotofication will be sent to both APNS
and APNSSandbox
, the endpoint for APNS
will be populated.
When you need the endpoint for APNSSandbox
, don't provide APNSSandbox
but a custom type in platforms
and provide a custom type
for the device.
Example
package main
import (
"log"
"os"
"github.com/capptions/pushnotification"
"github.com/aws/aws-sdk-go/aws"
"github.com/joho/godotenv"
)
func main() {
if err := godotenv.Load(); err != nil {
log.Fatal(err)
}
svc := Service{
Key: os.Getenv("KEY"),
Secret: os.Getenv("SECRET"),
Region: os.Getenv("REGION"),
// provide at least one of these, based on the devicetype
APNS: os.Getenv("APNS"),
APNSSandbox: os.Getenv("APNSSandbox"),
GCM: os.Getenv("GCM"),
Windows: os.Getenv("WINDOWS"),
Platforms: map[string]string{
"baidu": os.Getenv("baidu"),
},
}
device := &pushnotification.Device{
Token: os.Getenv("DEVICE_TOKEN"),
Type: os.Getenv("DEVICE_TYPE"), //'ios|android|windows|custom'
EndpointArn: os.Getenv("DEVICE_ENDPOINT_ARN"), //optional
}
err := svc.Send(device, &pushnotification.Data{
Subject: aws.String("Subject"),
Alert: aws.String("Nice test message"),

Setup SNS stuff on Amazon
Amazon SNS
Create platform application for each supported device type in Amazon SNS and remember the application ARN.
Amazon IAM
Create a user and add this policy. The 'resources' should list the application ARNs you created.

Devices
The endpoints for the device tokens will be added on the fly, you can however store the EndpointArn for reuse.
The endpoint will be stored in the Device struct. If the provided endpoint is empty, it will be created, otherwise it will be reused when possible.
Function 'IsCreated' will return if the endpoint is (re)created or not.
device := &pushnotification.Device{
Token: os.Getenv("DEVICE_TOKEN"),
Type: os.Getenv("DEVICE_TYPE"), //'ios|android|windows|custom'
EndpointArn: os.Getenv("DEVICE_ENDPOINT_ARN"), //optional
}
if device.IsCreated() {
log.Printf("New endpoint arn '%v' created for device token '%v'", device.EndpointArn, device.Token)
}
