假设我在同一个BrowserView
中有两个BrowserWindow
和一个UI按钮,允许用户在显示bv1
或bv2
之间切换(如Firefox,Chrome等浏览器中的“tab”系统,允许您在不同页面之间切换):
browserWindow = new BrowserWindow({ width: 1200, height: 600 });
let bv1 = new BrowserView({ webPreferences: { nodeIntegration: false }});
bv1.setBounds({ x: 0, y: 0, width: 1200, height: 600 });
bv1.webContents.loadURL('https://www.twitter.com');
let bv2 = new BrowserView({ webPreferences: { nodeIntegration: false }});
bv2.setBounds({ x: 0, y: 0, width: 1200, height: 600 });
bv2.webContents.loadURL('https://www.twitter.com');
browserWindow.setBrowserView(bv1);
当按下按钮(如浏览器中的“标签”)时:
browserWindow.setBrowserView(bv2);
我注意到这两个BrowserView
:
问题:如何将两个BrowserView
完全隔离在cookies / localStorage / history(因此bv1
可以连接到一个Twitter帐户和bv2
连接到另一个)?
所以,我设法让这个工作,但非常,非常,迂回。有效地会话劫持您自己的会话,保存并加载应用程序关闭/打开。下面的代码带有一些注释,前面有一些有用的链接。这在作为dev运行时以及在使用构建应用程序运行时有效。
您可能需要在此处查看可能存在的安全问题,例如在本地存储Cookie。
我在这个答案中唯一没有解决的问题是:
保持历史...重启电子应用程序后
