我尝试在方法内而不是在启动时添加Vue套接字群集连接。这是我研究的结果。我看到几个问题。我在一个名为connect()的方法中添加了连接指令,通过从另一个组件单击来调用此方法。它有效,但是,事件监听器存在问题。我试图使用Vue.extend添加一个将其添加到连接但它阻止对组件进行的任何更新。例如,在我的代码中,我添加了this.msg =“这是一个测试”;但添加事件监听器后,msg变异不起作用。
我还尝试使用这个来添加事件监听器。$ options.SeoScanEvents.nameofwebsocketmessage作为vue.extend的替代方案,但它确实可以工作。
此代码使用dummy vue.js应用程序的结构。因此,如果您想要复制此问题,您只需安装VUEJS应用程序的虚拟结构,然后使用以下内容替换main.js和HelloWorld.vue。然后你需要socketcluster.io中的默认server.js和worker.js在端口8000上运行。它应该返回一个随机数。
main.js
import Vue from 'vue'
import App from './App'
import router from './router'
import VueSocketCluster from 'vue-socket-cluster'
Vue.config.productionTip = false
/* eslint-disable no-new */
const vm = new Vue({
el: '#app',
router,
components: { App },
template: '<App/>',
SeoScanEvents:{
connect: function(data){ // I added it here to see in vm object if I could replicate the property. For sure it does not work because it comes before the connection directives.
console.log('socket connected')
console.log(data)
},
// ['error','connect','disconnect','connectAbort','connecting', etc ...] See socket cluster docs
error () {
//An error occurred on the connection name echo
},
connecting () {
},
// ...
// for hyphen separated events such as 'custom-error' use ...
customError () {
},/*
random(data){
console.log(data)
}*/
},
methods:{
connect(){
Vue.use(VueSocketCluster, {
connections: [{
name: 'SeoScan',
hostname: 'localhost',
secure: false,
port: 8000,
rejectUnauthorized: false
}]
})
var Comp = Vue.extend({
SeoScanEvents:{
random: function(data){
console.log(data);
}
}
});
new Comp().$mount('#app'); // this works but it blocks any updates on my vue component for example the this.msg=... below does not work
console.log(this);
/*
this.$options.SeoScanEvents.random = function random(data) { // this does not work
console.log(data) // should show the random numbers generated by the default server config file from Socket Cluster
}
*/
}
}
});

正确的解决方案是
<div class="rcbScroll rcbWidth" style="height:180px;width:100%;"> <div class="rcbCheckAllItems"><input type="checkbox" class="rcbCheckAllItemsCheckBox">Check All</div> <ul class="rcbList" style="list-style:none;margin:0;padding:0;zoom:1;"> <li class="rcbHovered "><input type="checkbox" class="rcbCheckBox">Dallas , Wanda</li> <li class="rcbItem "><input type="checkbox" class="rcbCheckBox">Parker , Tina</li> <li class="rcbItem "><input type="checkbox" class="rcbCheckBox">Plano , Samantha </li> <li class="rcbItem "><input type="checkbox" class="rcbCheckBox">Richardson , Christina</li> <li class="rcbItem "><input type="checkbox" class="rcbCheckBox">Dave , Test</li> <li class="rcbItem "><input type="checkbox" class="rcbCheckBox">clinician , test</li> <li class="rcbItem "><input type="checkbox" class="rcbCheckBox">Smith , Jasmin</li> </ul> </div>
然后,在导出默认值下添加组件(此处为HelloWorld.vue)事件侦听器
SeoScanEvents:{ connect:function(data){ console.log('socket connected') 的console.log(数据) }, 随机(数据){ 的console.log(数据) } }
在方法submit1中,而不是从根调用方法connect,调用将启动连接的方法:this。$ SeoScanClient.connect();
