laravel 广播例子

这里使用了私有频道和Presence 频道做了不同的例子:

Presence 频道当用户加入或发送消息该频道时,通知其它加入该频道的用户：

私有频道我这里定义了一个artisan命令发送消息给指定的用户:

php artisan command:push-message {user} {message}

第一个参数是发送哪个用户，第二个参数是需要发送的消息,如图:

可以帮助大家在看广播系统时结合例子起来看更深刻 :relaxed:

下载项目

git clone git@github.com:ningge123/laravel-echo-demo.git

执行:

composer install

下载前端资源

npm install

配置数据库:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=pusher
DB_USERNAME=homestead
DB_PASSWORD=secret

配置redis:

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

然后还需安装laravel-echo-server

npm install -g laravel-echo-server  # 这里是全局安装
