我想在WinForms應用程序中使用CefSharp瀏覽器控件以及LocalStorage機制。
問題是,應用程序中的瀏覽器控件更改爲LocalStorage不會影響其他瀏覽器窗口,並且不會從其他Chrome瀏覽器窗口獲取更改。
HTML在本地Chrome瀏覽器內部工作,並更改localstorage並獲取更改通知。
我錯過了什麼?WinForms CefSharp瀏覽器LocalStorage不工作
C#代碼:
public Form1()
{
InitializeComponent();
CefSharp.Cef.Initialize();
_browser = new ChromiumWebBrowser(URL_TO_LOAD);
_browser.BrowserSettings = new CefSharp.BrowserSettings()
{
ApplicationCacheDisabled = false,
FileAccessFromFileUrlsAllowed = true,
JavascriptDisabled = false,
LocalStorageDisabled = false,
WebSecurityDisabled = true,
JavaScriptOpenWindowsDisabled = false,
JavascriptDomPasteDisabled = false
};
_browser.Load(URL_TO_LOAD);
splitContainer1.Panel1.Controls.Add(_browser);
}
