请问如何实现代理解决跨域问题，然后怎么开启websocket

[gaofant101]

用了http://vuejs-templates.github.io/webpack/proxy.html 这个方案，还是不行（我访问的是另外一台机器的端口）。而且config.js里面proxyTable格式是固定的，我需要怎么正确配置才能跨域；

proxyTable: {
       '*': 'http://192.168.1.30:7122'
}

我也没有找到如何开启ws的方案；
用了https://www.npmjs.com/package/http-proxy-middleware 插件下的配置方式书写，就报错；

@EvanHunt I'm pretty sure issue belongs here: https://github.com/vuejs-templates/webpack

Anyways, to configure proxy middleware you can change options object before it's used here: https://github.com/vuejs-templates/webpack/blob/dist/template/build/dev-server.js#L42

WebSocket options for http-proxy-middleware are defined here: https://github.com/chimurai/http-proxy-middleware#websocket

@zigomir tks, I'll take a look at API.

@EvanHunt 你好 我想问一下最后是怎么在proxyTable中设置的websocket连接 我也遇到了这样的问题 谢谢

@smilebuz 抱歉今天才注意到,
vue-cli中代理用的是 http-proxy-middleware 插件
你可以去 https://github.com/chimurai/http-proxy-middleware#websocket看示例代码
设置 websocket 只需要开启配置就行了

...
proxyTable: {
     '/api': {
         target: `http:${host}:${port}`,
         changeOring: true,
         ws: true,
     }
},
...

Websocket request is able to cross domains. Why is proxy needed for it?
