问如何在没有创建-反应-应用程序的情况下配置CRA中的代理？

EN

const httpProxy = require('http-proxy');

const proxy = httpProxy.createProxyServer({
  secure: false,
  changeOrigin: true,
  target: 'https://someOriginURL.com',
  // could be an IP address target: 'https://XX.XX.XXX.XXX/',
}).listen(3500, () => console.log('Proxy running on port 3500'));

// Intercepts the request 
proxy.on('proxyReq', function(proxyReq, req, res, options) {
  console.log(req);
  // Set the headers of the intercepted request
  proxyReq.setHeader('Origin', 'https://yourorigin.com');
  // remove any headers you want 
  // proxyReq.removeHeader('authorization');

  res.oldWriteHead = res.writeHead;
  res.writeHead = function(statusCode, headers) {
    res.setHeader('Access-Control-Allow-Origin', '*');
    res.oldWriteHead(statusCode, headers);
  }
});

node proxy.js
