  mode: "release"
  ssl: false
  cert_path: "cert.pem"
  key_path: "key.pem"

api:
  push_uri: "/api/push"
  stat_go_uri: "/api/status"

android:
  enabled: true
  apikey: "YOUR_API_KEY"

ios:
  enabled: false
  pem_cert_path: "cert.pem"
  pem_key_path: "key.pem"
  production: false

log:
  format: "string" # string or json
  access_log: "stdout" # stdout: output to console, or define log path like "log/access_log"
  access_level: "debug"

## Basic Usage

How to send push notification using `gopush` command? (Android or iOS)

### Download a binary

The pre-compiled binaries can be downloaded from [release page](https://github.com/appleboy/gopush/releases).

### Send Android notification

Send single notification with the following command.

```bash
$ gopush -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
$ gopush -ios -m="your message" -i="API Key" -t="Device token"
```

* `-m`: Notification message.
* `-i`: Apple Push Notification Certificate path (`pem` file).
* `-t`: Device token.

The default endpoint is APNs development. Please add `-production` flag for APNs production push endpoint.

```bash
$ gopush -ios -m="your message" -i="API Key" -t="Device token" -production
```

## Run gopush web server

Please make sure your [config.yml](config/config.yml) exist. Default port is `8088`.

```bash
$ gopush -c config.yml
```

Test status of api server using [httpie](https://github.com/jkbrzt/httpie) tool:

```bash
$ http -v --verify=no --json GET https://localhost:8088/api/status
```

## Run gopush in Docker

Set up `gopush` in the cloud in under 5 minutes with zero knowledge of Golang or Linux shell using our [gopush Docker image](https://hub.docker.com/r/appleboy/gopush/).

```bash
$ docker pull appleboy/gopush
$ docker run -name gopush -p 80:8088 appleboy/gopush
```

Testing your gopush server.

```bash
$ http -v --verify=no --json GET http://your.docker.host/api/status
```

### Web API

Gopush support the following API.

* **GET**  `/api/status` Golang cpu, memory, gc, etc information. Thanks for [golang-stats-api-handler](https://github.com/fukata/golang-stats-api-handler).
* **POST** `/api/push` push ios and android notifications.

Simple send iOS notification example, the `platform` value is `1`:

```json
{
  "notifications": [
    {
      "tokens": ["token_a", "token_b"],
      "platform": 1,
      "message": "Hello World iOS!"
    }
  ]
}
```

Simple send Android notification example, the `platform` value is `2`:

```json
{
  "notifications": [
    {
      "tokens": ["token_a", "token_b"],
      "platform": 2,
      "message": "Hello World Android!"
    }
  ]
}
```
