javascript - 检测浏览器或 CEF/Electron

Question

有什么方法可以检测我的 JS 代码是在真正的浏览器中运行，还是在 CEF 或 Electron 等工具包中运行？

Answer 1

如果您可以控制托管 CEF 控件的应用程序，您可以注册一个要绑定(bind)的对象，如下所示:

chromeBrowser.JavascriptObjectRepository.Register("boundAsync", new CefCustomObject(chromeBrowser), true);

CefCustomObject 类:

class CefCustomObject
{
    // Declare a local instance of chromium and the main form in order to execute things from here in the main thread
    private static ChromiumWebBrowser _instanceBrowser = null;

    public CefCustomObject(ChromiumWebBrowser originalBrowser)
    {
        _instanceBrowser = originalBrowser;
    }
}

然后您可以检查此对象是否存在于 Web 应用程序中。Web 应用程序中的 JavaScript:

(async function()
{
    if ("CefSharp" in window) {
        await CefSharp.BindObjectAsync("boundAsync");

        if (boundAsync) {
            alert('running inside CEF')
        }
    }
})();
