• 主进程background.js接收渲染进程的打开要求

  const { ipcMain, shell } = require('electron');
  ipcMain.on('openDir', async (event, path) => {
      console.log('打开路径', path);
      try {
        const res = await shell.openPath(path);
        console.log('ipcMain.on ~ res', res);
      } catch (error) {
        console.log('ipcMain.on ~ error', error);
      }
    });
  

• 渲染进程发送路径

  window?.ipcRenderer?.send('openDir', path);
  

• preload.js

  const { contextBridge: bridge, ipcRenderer } = require('electron');
  bridge.exposeInMainWorld('ipcRenderer', {
    send: (channel, data) => ipcRenderer.send(channel, data),
    on: (channel, fun) => ipcRenderer.on(channel, fun),
  });
