See the [YAML config example](config/config.yml): ```yaml core: port: "8088" worker_num: 8 queue_num: 8192 max_notification: 100 mode: "release" ssl: false cert_path: "cert.pem" key_path: "key.pem" http_proxy: "" # only working for GCM server pid: enabled: true path: "gorush.pid" override: true api: push_uri: "/api/push" stat_go_uri: "/api/stat/go" stat_app_uri: "/api/stat/app" config_uri: "/api/config" sys_stat_uri: "/sys/stats" android: enabled: true apikey: "YOUR_API_KEY" max_retry: 0 # resend fail notification, default value zero is disabled ios: enabled: false key_path: "key.pem" password: "" # certificate password, default as empty string. production: false max_retry: 0 # resend fail notification, default value zero is disabled log: format: "string" # string or json access_log: "stdout" # stdout: output to console, or define log path like "log/access_log" access_level: "debug" error_log: "stderr" # stderr: output to console, or define log path like "log/error_log" error_level: "error" hide_token: true stat: engine: "memory" # support memory, redis, boltdb, buntdb or leveldb redis: addr: "localhost:6379" password: "" db: 0 boltdb: path: "bolt.db" bucket: "gorush" buntdb: path: "bunt.db" leveldb: path: "level.db" ``` ## Basic Usage 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). With `Go` installed ``` $ go get -u github.com/appleboy/gorush ``` On linux ```sh $ wget https://github.com/appleboy/gorush/releases/download/v1.7.1/gorush-v1.7.1-linux-amd64 -O gorush ``` On OS X ```sh $ wget https://github.com/appleboy/gorush/releases/download/v1.7.1/gorush-v1.7.1-darwin-amd64 -O gorush ``` On Windows ```sh $ wget https://github.com/appleboy/gorush/releases/download/v1.7.1/gorush-v1.7.1-windows-amd64.exe -O gorush.exe ``` ### Command Usage ``` ________ .__ / _____/ ____ _______ __ __ ______| |__ / \ ___ / _ \\_ __ \| | \/ ___/| | \ \ \_\ \( <_> )| | \/| | /\___ \ | Y \ \______ / \____/ |__| |____//____ >|___| / \/ \/ \/ Usage: gorush [options] Server Options: -p, --port Use port for clients (default: 8088) -c, --config Configuration file -m, --message Notification message -t, --token Notification token --proxy Proxy URL (only for GCM) iOS Options: -i, --key certificate key file path -P, --password certificate key password --topic iOS topic --ios enabled iOS (default: false) --production iOS production mode (default: false) Android Options: -k, --apikey Android API Key --android enabled android (default: false) Common Options: -h, --help Show this message -v, --version Show version ``` ### 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. * `--proxy`: Set http proxy url. (only working for GCM) ### 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` or `p12` file). * `-t`: Device token. * `-topic`: The topic of the remote notification. * `-password`: The certificate password. 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 ``` ## Run gorush web server Please make sure your [config.yml](config/config.yml) exist. Default port is `8088`. ```bash $ gorush -c config.yml ``` Get go status of api server using [httpie](https://github.com/jkbrzt/httpie) tool: ```bash $ http -v --verify=no --json GET https://localhost:8088/api/stat/go ``` ## Web API Gorush support the following API. * **GET** `/api/stat/go` Golang cpu, memory, gc, etc information. Thanks for [golang-stats-api-handler](https://github.com/fukata/golang-stats-api-handler). * **GET** `/api/stat/app` show notification success and failure counts. * **GET** `/api/config` show server yml config file. * **POST** `/api/push` push ios and android notifications. ### GET /api/stat/go Golang cpu, memory, gc, etc information.
