一、配置background.js

 win = new BrowserWindow({
    webPreferences: {
      nodeIntegration: true, // 使渲染进程拥有node环境
      //关闭web权限检查，允许跨域
      webSecurity: false,
      // Use pluginOptions.nodeIntegration, leave this alone
      // See nklayman.github.io/vue-cli-plugin-electron-builder/guide/security.html#node-integration for more info
      nodeIntegration: process.env.ELECTRON_NODE_INTEGRATION,
      contextIsolation: !process.env.ELECTRON_NODE_INTEGRATION,
    },
  });

参考官网：http://electronjs.p2hp.com/docs/latest/api/browser-window

二、配置axios基础路径

axios.defaults.baseURL = 'http://xx.xx.xx.xx';
