本文介绍了Winforms，CefSharp:不显示基本身份验证的身份验证弹出窗口的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在努力在WinForms应用程序中添加cefsharp.我们的网站使用基本身份验证进行访问，但是CefSharp不会显示该弹出窗口.我发现了
解决方案
对我有用的解决方案:

private void InitializeChromium(){chromeBrowser =新的ChromiumWebBrowser("https://www.google.com"){Dock = DockStyle.Fill，};chromeBrowser.RequestHandler = new MyRequestHandler("actual_username"，"actual_password");this.Controls.Add(chromiumBrowser);} I am working on adding cefsharp in a WinForms application. Our website uses basic authentication for access, but CefSharp wont show that popup. I found out this and this, but Visual studio doesn't implement the interface and complains about AuthDialog being an unknown class. I come from Java side, not much idea about classes in Winforms, but I cant find AuthDialog. What am I doing wrong?
Code :
bool IRequestHandler.GetAuthCredentials(IWebBrowser browser, bool isProxy, string host, int port,
string realm, string scheme, ref string username, ref string password)
{
//NOTE: If you do not wish to implement this method returning false is the default behaviour
// We also suggest you explicitly Dispose of the callback as it wraps an unmanaged resource.
// shyam - original implemenation.
//callback.Dispose();
//return false;
bool handled = false;
// Instantiate the dialog box
AuthDialog dlg = new AuthDialog(host); // create new dialog with username and password field.
// Open the dialog box modally
dlg.ShowDialog();
if (dlg.DialogResult == System.Windows.Forms.DialogResult.OK)
{
// The user did not cancel out of the dialog. Retrieve the username and password.
callback.Continue(dlg.UserName, dlg.Password);
handled = true;
}
return handled;
}

解决方案
The solution which worked for me :
public class MyRequestHandler : IRequestHandler
{
private string userName;
private string password;
public MyRequestHandler(string userName, string password)
{
this.userName = userName;
this.password = password;
}

//Example of how to set Referer

}
public void OnResourceRedirect(IWebBrowser browserControl, IBrowser browser, IFrame frame, IRequest request, IResponse response, ref string newUrl)
{
}
}
and call it in chromium browser call it like this :
private void InitializeChromium()
{
chromiumBrowser = new ChromiumWebBrowser("https://www.google.com")
{
Dock = DockStyle.Fill,
};
chromiumBrowser.RequestHandler = new MyRequestHandler("actual_username","actual_password");
this.Controls.Add(chromiumBrowser);
}
