How to send push notification using `gorush` command? (Android or iOS)
|
|
|
|
### Download a binary

|
The pre-compiled binaries can be downloaded from [release page](https://github.com/appleboy/gorush/releases).
|
|
|
|
### Send Android notification
|
|
|
|
Send single notification with the following command.
|
|
|
|
```bash
|
|
$ gorush -android -m="your message" -k="API Key" -t="Device token"
|
|
```
|
|
|
|
* `-m`: Notification message.
|
|
* `-k`: [Google cloud message](https://developers.google.com/cloud-messaging/) api key
|
|
* `-t`: Device token.
|
|
|
|
### Send iOS notification
|
|
|
|
Send single notification with the following command.
|
|
|
|
```bash
|
|
$ gorush -ios -m="your message" -i="your certificate path" -t="device token" -topic="apns topic"
|
|
```
|
|
|
|
* `-m`: Notification message.
|
|
* `-i`: Apple Push Notification Certificate path (`pem` file).
|
|
* `-t`: Device token.
|
|
* `-topic`: The topic of the remote notification.
|
|
|
|
The default endpoint is APNs development. Please add `-production` flag for APNs production push endpoint.

|
|
|
```bash

$ gorush -ios -m="your message" -i="your certificate path" -t="device token" -production
|
|
```
