开发公司Vue项目里Websocket的使用

开发公司由于项目需求有要使用长链接，开发公司我们普通的http开发公司请求如果用轮询的方式开发公司与服务端通讯就很消耗资源。开发公司我们一起来学习一下在开发公司里如何使用websocket,开发公司本文纯属个人观点，开发公司如果有不正确的地方请开发公司大家批评指正，开发公司技术无高低，开发公司谦虚学习的心态我认为很重要，天外有天人外有人。

判断浏览器是否支持的方法

比较直观的方式是直接判断全局对象中是否包含WebSocket对象即可：

if( typeof(WebSocket) != "function" ) {    alert("您的浏览器不支持Websocket通信协议，请更换浏览器为Chrome或者Firefox再次使用！")  }

但是这种方式不严谨，在 Android 中，即使浏览器不支持 WebSocket ，但是它还是存在这个属性。所以可以使用下面的方法：

if (typeof WebSocket != 'undefined') {    console.log("您的浏览器支持Websocket通信协议")}else{    alert("您的浏览器不支持Websocket通信协议，请使用Chrome或者Firefox浏览器！")}
1

5

或者是这种方法：

if (!!window.WebSocket && window.WebSocket.prototype.send) ｛     console.log("您的浏览器支持Websocket通信协议")}else{    alert("您的浏览器不支持Websocket通信协议，请使用Chrome或者Firefox浏览器！")}

Vue项目里使用websocket的实例

上面这个页面是我所做项目里的某个页面，由于硬件资源监测和网络性能监测两个板块需要传递给服务端不同的参数来获取数据，传参分别如下:

 { message: "sys_info" }
1

{ message: "net_info" }
1

我们需要建立2个不同的长链接。我们项目都是统一在public文件夹下的config.js里统一配置，不管是http请求还是websocket，代码如下：

然后在一个js文件里将其封装成一个函数并暴露出去，代码如下：

然后在我们要使用到的组件里引入，并在data里定义两个websock实例，然后再在mounted里初始化两个websock实例，最后在destroyed销毁页面时一并销毁两个websock实例，代码如下：

然后我们在methods里看看初始化websocket的两个方法怎么写的，代码如下:


这里为了考虑各大浏览器是否兼容websocket,所以加了一个判断语句：

 if (typeof WebSocket === "undefined")        return console.log("您的浏览器不支持websocket");
