fixed bug:ionic Proxies don't work

[791060555]

There is a bug!

I have a way to solve the problem

1.use 'http-proxy-middleware' replace proxy-middleware

Thanks @791060555

node_modules//@ionic/app-scripts/dist/dev-server/http-server.js

10 var proxyMiddleware = require('http-proxy-middleware');

 47                 //if (proxy.proxyNoAgent) {
 48                 //    opts.agent = false;
 49                 //}
 50                 //opts.rejectUnauthorized = !(proxy.rejectUnauthorized === false);
 51                 app.use(proxy.path, proxyMiddleware({
 52                   target: proxy.proxyUrl,
 53                   changeOrigin: true
 54                 }));
 55                 //app.use(proxy.path, proxyMiddleware(opts));

Work like a charm!
