Question

我有一个使用Angular 5，node-adodb和Electron的应用程序（参见下面的package.json）

在开发模式下运行Angular和Electron时，一切正常。当我调用Electron'ipcMain.on（'select'...）（见下文）时，SQL'select'对数据库完成，然后返回我的Angular应用程序。

当我使用Electron软件包打包所有内容时，相同的SQL“select”根本不会返回。没有'那么'而不是'赶上'。

我该如何调试这种情况？你有解决方案建议解决这个问题吗？

提前致谢。

main.js

ipcMain.on('select', (event, type, sql) => {

    const reply = 'reply-select-' + type;

    // Code run until here

    connection = ADODB.open(databasePath);

    // Code run until here

    connection
      .query(sql)
      .then((data) => {

        // Code does not go here

        event.sender.send(reply, { status: 0, message: '', data: data });
      })
      .catch((error) => {

        // Code does not go here

        event.sender.send(reply, { status: 1, message: error.message, data: {} });
      });
  });

为什么使用IPC和主要流程来执行此操作？可以在渲染器进程中访问节点的完整功能，可以通过开发工具进行调试。

主进程只应用于创建BrowserWindows和访问电子API，这些API在文档中标记为只能通过主进程访问。

Check out this article了解主/渲染器与它们用途之间差异的更多细节。
