背景:
项目开发客服聊天系统,使用socket.io进行开发,前端采用vue-element-admin,后端语言php,项目在本地运行功能正常,但是发布到测试环境的时候,socket的连接一直不成功,可以成功返回socketid,但是请求时并没有将sid作为参数进行请求。
解决过程:
1.首先从socket建立连接开始入手,连接是可以成功的,而且返回值也正常,
2.然后对比socket client和socket server的版本,版本一致,
3. 前项目使用的是-socket.io.js,新项目则采用npm加载的socker.js,为了排除两者之间的不同,将js替换为本地引入的js,问题也没有得到解决,
4.查看polling-xhr.js,确定request的参数,发现是在两个环境的参数不一致,
1 XHR.prototype.request = function (opts) { 2 opts = opts || {}; 3 opts.uri = this.uri(); 4 opts.xd = this.xd; 5 opts.xs = this.xs; 6 opts.agent = this.agent || false; 7 opts.supportsBinary = this.supportsBinary; 8 opts.enablesXDR = this.enablesXDR; 9 opts.withCredentials = this.withCredentials; 10 11 // SSL options for Node.js client 12 opts.pfx = this.pfx; 13 opts.key = this.key; 14 opts.passphrase = this.passphrase; 15 opts.cert = this.cert; 16 opts.ca = this.ca; 17 opts.ciphers = this.ciphers; 18 opts.rejectUnauthorized = this.rejectUnauthorized; 19 opts.requestTimeout = this.requestTimeout; 20 21 // other options for Node.js client 22 opts.extraHeaders = this.extraHeaders; 23 console.log(‘prototype.opts‘,opts); 24 return new Request(opts); 25 };
5.继续寻找参数来源的问题,发现mock/index.js中有处理参数的部分,
1 export function mockXHR() { 2 // mock patch 3 // https://github.com/nuysoft/Mock/issues/300 4 Mock.XHR.prototype.proxy_send = Mock.XHR.prototype.send 5 console.log(‘Mock.XHR.prototype.proxy_send‘,Mock.XHR.prototype.proxy_send); 6 Mock.XHR.prototype.send = function() { 7 console.log(‘custom.xhr‘,this.custom.xhr); 8 console.log(‘responseType‘,this.responseType); 9 console.log(‘...arguments‘,...arguments); 10 if (this.custom.xhr) { 11 12 this.custom.xhr.withCredentials = this.withCredentials || false 13 14 if (this.responseType) { 15 this.custom.xhr.responseType = this.responseType 16 } 17 } 18 this.proxy_send(...arguments) 19 }
6.由于mockXHR为export function,寻找使用mockXHR的文件,最终在src/main.js中找到了原因,
import { mockXHR } from ‘../mock‘; if (process.env.NODE_ENV === ‘production‘) { mockXHR(); }
7.此处为vue-element-admin的说明,
When we use Mock.js
to simulate data locally, the real-world api method is used online. This is similar to the easy-mock method above. We mainly judge that when it is an online environment, we use real-world api. We only import Mock.js
locally.
// main.js // use environment variables to determine is required if (process.env.NODE_ENV === ‘development‘) { require(‘./mock‘) // simulation data }
Mock data is only import in the local environment.
由此可见,是项目前端将mock的引入场景判断写为了生产环境,导致了socket的参数被处理,无法正常建立连接,至此暂时告一段落。
后记:这个坑找了好久,头发最起码消耗了86根,希望大家在使用第三方库的时候,一定要看好文档
