reactjs - React 应用程序未命中代理（package.json 文件）中描述的 url

问题描述

"proxy": "http://localhost:3001"在我的 package.json 中，express 服务器在此端口（ 3001 ）上运行，但是每次我从 react 发出请求时，它都会在运行 react 应用程序的 3000 端口上运行

包.json

    "antd": "^3.10.2",

  ]
}

setupProxy.js

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

module.exports = function(app) {
  app.use(proxy('/api/*', { target: 'http://localhost:3001' }));
};
