在服务器时socket.io报错

[xiaobenSB]

failed: Error during WebSocket handshake: 'Connection' header value must contain 'Upgrade'

使用了nginx做代理

[egg-bot]

Translation of this issue:

---

socket.io error on server

Failed: Error during WebSocket handshake: 'Connection' header value must contain 'Upgrade'

Use nginx as a proxy

[BaffinLee]

nginx 配置发一下

[xiaobenSB]

其实不配nginx，在本地也会报握手协议400,不知是不是用server.js启动项目原因，使用npm run dev不会

不是 egg-scripts 启动的吗，server.js 是什么内容？

[xiaobenSB]

const egg = require('egg');

const workers = Number(process.argv[2] || require('os').cpus().length); egg.startCluster({ workers, baseDir: __dirname, });

[Ailein]

server.js

sticky: true ， 配置下

[xiaobenSB]

不显示握手协议，谢谢了

[xiaobenSB]

不行了，过一会控制台自动又报出握手协议

[xiaobenSB]

在前端页面 transports数组设为'polling ‘’ const socket = io('/ioo', {

// 实际使用中可以在这里传递参数
query: {
  room: 'demo',
  userId: `client_${Math.random()}`,
},
transports: [
'polling'

], });

这样还没报握手协议

[thonatos]

• nginx 配置参考文档
• 应用需要设置 sticky，自定义启动同样需要设置
• 前端协议非必选，填写指定协议表示仅启用改协议

如果依然不能解决问题，建议提供最小可复现仓库，这样提问无法判断那边是什么状况。
