如果你的项目没有用到sockjs,vuecli3 运行npm run serve 之后network里面一直调用一个接口: http://localhost:8080/sockjs-node/info?t=1556418283950 net:: ERR_CONNECTION_REFUSED 原因:network里一直调用的这个借口其实是不存在的,所以导致一直报错。 方案:从根源上关闭此调用 1、node_modules/sockjs-client/dist/sockjs.js 2、代码的1605行注释 // self.xhr.send(payload); #ps:可在代码开发完成后关闭,会同步关闭热加载 ———————————————— 版权声明:本文为CSDN博主「H5女王」的原创文章,遵循 CC 4.0 BY-SA 版权协议,转载请附上原文出处链接及本声明。 原文链接:https://blog.csdn.net/H5_QueenStyle12/article/details/100031213 来源: https://www.cnblogs.com/fxwoniu/p/11579096.html

websocket+sockjs+stompjs详解及实例

最近有项目需求要用到websocket,刚开始以为很简单,但是随着遇到问题,深入了解,才知道websocket并不是想象中的那么简单,这篇文章主要是考虑websocket在客户端的使用。 1.http与websocket http超文本传输协议,大家都非常熟悉,http有1.0、1.1、 2.0几个版本,从http1.1起,默认都开启了Keep-Alive,保持连接持续性,简单地说,当一个网页打开完成后,客户端和服务器之间用于传输http数据的TCP连接不会关闭,如果客户端再次访问这个服务器上的网页,会继续使用这一条已经建立的连接,这样就降低了资源的消耗优化性能,但是Keep-Alive也是有时间限制的,还有一个客户端只能主动发起请求才能获取返回数据,并不能主动接收后台推送的数据,websocket便应运而生。 websocket 是 html5 新增加特性之一,目的是浏览器与服务端建立全双工的通信方式,解决 http 请求-响应带来过多的资源消耗,同时对特殊场景应用提供了全新的实现方式,比如聊天、股票交易、游戏等对对实时性要求较高的行业领域。 http与websocket都是基于TCP(传输控制协议)的,websocket可以看做是对http协议的一个补充 2.SockJs SockJS是一个JavaScript库,为了应对许多浏览器不支持WebSocket协议的问题

什么是SockJS? SockJS是一个提供Websocket通信的JavaScript库,目的是实现在浏览器与服务器之间低延迟、全双工、跨域通信,它提供跨浏览器的统一API,即使不支持HTML5 Websocket的浏览器也能通过SockJS实现Websocket通信,SockJS支持不同的后端脚本语音,包括NodeJS、Python、Java等,这里主要介绍SockJS-node,即支持NodeJS的版本。 SockJS-node server SockJS-node 是浏览器端运行的SockJS-client库对应的服务端,由CoffeeScript编写。 安装sockjs-node,首先确认你的机器已经安装NodeJS,然后执行: npm install sockjs 你或许有安全方面的考虑,可以安装 rbytes 库,SockJS将在rbytes可用时用到它,当然,如果不安装rbytes或安装失败,也不会影响SockJS的正常使用: npm install rbytes 下列的语句将创建一个简单的SockJS服务端: var http = require('http'); var sockjs = require('sockjs'); var echo = sockjs.createServer(); echo.on('connection', function(conn

springBoot -webSocket 基于STOMP协议交互

浅谈WebSocket WebSocket是在HTML5基础上单个TCP连接上进行全双工通讯的协议,只要浏览器和服务器进行一次握手,就可以建立一条快速通道,两者就可以实现数据互传了。说白了,就是打破了传统的http协议的无状态传输(只能浏览器请求,服务端响应),websocket全双工通讯,就是浏览器和服务器进行一次握手,浏览器可以随时给服务器发送信息,服务器也可以随时主动发送信息给浏览器了。对webSocket原理有兴趣的客官,可以自行百度。 2.环境搭建 因为是根据项目的需求来的,所以这里我只介绍在SpringBoot下使用WebSocket的其中一种实现【STOMP协议】。因此整个工程涉及websocket使用的大致框架为SpringBoot+Maven+websocket,其他框架的基础搭建,我这里就不说了,相信各位也都很熟悉,我就直接集成websocket了。 在pox.xml加上对springBoot对WebSocket的支持: <!-- webSocket --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-websocket</artifactId> </dependency> 这样SpringBoot就和WebSocket集成好了

How to set up an apache proxy for Meteor/SockJS and WebSocket?

自作多情 提交于 2019-11-28 20:55:03
I have an apache proxy for a meteor app and apache and meteor are on two separate machines. I need it that way as apache has to serve a lot of real websites and it wouldn't be a good idea to install the meteor app on this machine due to its limited resources. However the WebSocket handshake fails with response code 400 "Can upgrade only to websocket" if I try to connect from the outside via the proxy. Everything works fine when I connect from within the LAN directly to the meteor machine. When WebSocket fails SockJS/Meteor falls back to XHR but unfortunately this brings up some bugs in the app

How to send message to client through websocket using Spring

问题 I try to use Spring with websocket. I started my investigation with this tutorial. In my side client I have something like that to initialize the connection to the server : function connect() { var socket = new SockJS('/myphotos/form'); stompClient = Stomp.over(socket); stompClient.connect({}, function(frame) { setConnected(true); console.log('Connected: ' + frame); stompClient.subscribe('/topic/greetings', function(greeting){ showGreeting(JSON.parse(greeting.body).content); }); }); } It
