如何在http-proxy-middleware v3.0中正确配置多个代理以避免空白页面？

Question

const { createProxyMiddleware } = require('http-proxy-middleware');

module.exports = function (app) {
  app.use(
    '/res',
    createProxyMiddleware({
      target: 'http://127.0.0.1:7001',
      changeOrigin: true,
    })
  );

  app.use(
    '/api',
    createProxyMiddleware({
      target: 'http://127.0.0.1:7001',
      changeOrigin: true,
    })
  );

  app.use(
    '/static',
    createProxyMiddleware({
      target: 'http://127.0.0.1:7001',
      changeOrigin: true,
    })
  );
};

这样配置项目跑起来是空白的
