sockjs-node net::ERR_CONNECTION_REFUSED [重复]

Question

我用 vue cli 创建了一个全新的微型 webapp，所以除了空的 vue-cli 脚手架带来的东西之外，没有添加任何东西：

(base) marco@pc:~/vueMatters/testproject$ npm run serve


> testproject@0.1.0 serve /home/marco/vueMatters/testproject
> vue-cli-service serve

INFO Starting development server...
98% after emitting CopyPlugin

DONE Compiled successfully in 1409ms 8:14:46 PM


App running at:
- Local: localhost:8080
- Network: 192.168.1.7:8080

Note that the development build is not optimized.
To create a production build, run npm run build.

并收到此错误消息：

GET https://localhost/sockjs-node/info?t=1580228998416 net::ERR_CONNECTION_REFUSED

节点--版本 v12.10.0

npm -v 6.13.6

webpack-cli@3.3.10

Ubuntu 18.04.03 服务器版

/var/log/nginx/error.log 的最后几行：

如何解决问题？

Answer 1

您需要在套接字连接中指定 SSL 证书。

这是参考。

var options = {
  key: fs.readFileSync('./file.pem'),
  cert: fs.readFileSync('./file.crt')
};

var server = https.createServer(options, app);
var io = require('socket.io')(server);
