yarn解决跨域

yarn add http-proxy-middleware@1.0.1

在 src 文件夹下 创建 setupProxy.js 文件

const { createProxyMiddleware } = require('http-proxy-middleware');
  
module.exports = function (app) {
  app.use(
    createProxyMiddleware(
      '/api',
      {
        target: 'http://106.13.9.213:9000',
        changeOrigin: true,
        pathRewrite: {
          '/api': ''
        }
      }
    )
  );
};

在页面中
async componentDidMount() {
  let res = await axios.get('/api/admin/category');
  console.log(res);
}
