#### 安装
|
|
|
|
|
```bash
|
|
|
|
|
npm install vue-socket.io --save
|
|
|
|
|
```
|
|
|
|
|
main.js 代码
|
|
|
|
|
```javascript
|
|
|
|
|
import Vue from 'vue'
|
|
|
|
|
import store from './store'
|
|
|
|
|
import App from './App.vue'
|
|
|
|
|
import VueSocketIO from 'vue-socket.io'
|
|
|
|
|
|
|
|
|
|
const options = { path: '/my-app/' }; //Options object to pass into SocketIO
|
|
|
|
|
|
|
|
|
|
Vue.use(new VueSocketIO({
|
|
|
|
|
debug: true,
|
|
|
|
|
connection: 'http://metinseylan.com:1992',
|
|
|
|
|
options: {
|
|
|
|
|
path: options.path
|
|
|
|
|
}
|
|
|
|
|
})
|
|
|
|
|
);
|
|
|
|
|
|
|
|
|
|
new Vue({
|
|
|
|
|
router,
|
|
|
|
|
store,
|
|
|
|
|
render: h => h(App)
|
|
|
|
|
}).$mount('#app')
|
|
|
|
|
```
|
|
|
|
|
#### 局部使用
|
|
|
|
|
组件的话就在基础属性里加上`sockets` 对象， 里面写上自己要监听的事件名
|
|
|
|
|
```javascript
|
|
|
|
|
new Vue({
|
|
|
|
|
sockets: {
|
|
|
|
|
connect: function () {
|
|
|
|
|
console.log('socket connected')
|
|
|
|
|
},
|
|
|
|
|
customEmit: function (data) {
|
|
|
|
|
console.log('this method was fired by the socket server. eg: io.emit("customEmit", data)')
|
|
|
|
|
}
|
|
|
|
|
},
|
|
|
|
|
methods: {
|
|
|
|
|
clickButton: function (data) {
|
|
|
|
|
// $socket is socket.io-client instance
|
|
|
|
|
this.$socket.emit('emit_method', data)
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
})
|
|
|
|
|
```
|
|
|
|
|
#### 动态使用
|
|
|
|
|
如果你需要在运行时动态消费事件，你可以在Vue组件中使用' subscribe '和' unsubscribe '方法
|
|
|
|
|
```javascript
|
|
|
|
|
|
|
|
|
|
mounted() {
|
|
|
|
|
this.sockets.subscribe('EVENT_NAME', (data) => {
|
|
|
|
|
this.msg = data.message;
|
|
|
|
|
});
|
|
|
|
|
},
|
|
|
|
|
beforeDestroy() {
|
|
|
|
|
this.sockets.unsubscribe('EVENT_NAME');
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
#### vuex 模式
|
|
|
|
|
当你在安装中设置存储参数时，' Vue-Socket。io '将开始发送事件到Vuex商店。如果你为vuex设置了两个前缀，
|
|
|
|
|
你可以同时使用' actions '和' mutations '。但是，最好的使用方法就是" actions "
|
