reactjs - 如何在 reactjs 中访问后端数据（通过 create-react-app 的 npm start）

Question

npm run build因此，如果我的应用程序通过它通常的地址运行，我可以获取数据。但是npm start它不知道/（无法到达）指定的位置。

那么我该怎么做才能让它在两端都起作用呢？

包.json

{
  "name": "reactjs",
  "version": "0.1.0",
  "private": true,
  "homepage": "/reactjs/build",
  "devDependencies": {
    "lite-server": "^2.2.2",
    "react-scripts": "0.8.4"
  },  
  "dependencies": {
    "datatables.net": "^1.4.2",
    "datatables.net-dt": "^1.4.2",
    "griddle-react": "^0.7.1",
    "jquery": "^3.1.1",
    "react": "^15.4.1",
    "react-dom": "^15.4.1",
    "react-router": "^3.0.0"
  },  
  "scripts": {
    "start": "react-scripts start eslint-disable",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject",
    "dev": "lite-server -c config/bs-config.js"
  }
}
