Question

我正在尝试在其关闭处理程序中访问远程窗口

    const BrowserWindow = this.$electron.remote.BrowserWindow;
    let win = new BrowserWindow({ width: 800, height: 600 });
    const closeHandler = (event) => {
      console.log(event.sender.getURL());
    };
    win.on('close', closeHandler);
    win.on('closed', () => {
      win.removeListener('close', closeHandler);
      win = null;
    });

我收到以下错误

Uncaught Error: Could not call remote function 'getURL'. Check that the function signature is correct. Underlying error: Object has been destroyed

我认为这是因为注册到远程对象的回调被异步调用-https://github.com/electron/electron/blob/master/docs/api/remote.md#passing-callbacks-to-the-main-process

这样在执行回调时窗口已经被破坏了吗？

但是那没有意义，因为是将其设置为null的关闭事件，并允许主进程对其进行垃圾收集。

在关闭回调上访问远程窗口内的窗口
