WinFormsOIDC

建立winform项目

安装包 IdentityModel.OidcClient 以及 Microsoft.Web.WebView2 , 项目使用x64运行

  
    WinExe
    net8.0-windows
    enable
    true
    enable
  

  
    
    
  

拖放一个TextBox控件

Form1.cs 代码

            Browser = new WinFormsWebView()
        };

        _oidcClient = new OidcClient(options);

        Login();
    }

    private async void Login()
    {
        LoginResult loginResult;

        try

            return;
        }


        if (loginResult.IsError)

            MessageBox.Show(this, loginResult.Error, "Login", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
        else

添加一个类 WinFormsWebView.cs

代码

        {
            Name = "WebAuthentication",
            Text = title,
            Width = width,
            Height = height
        })
    { }

    public async Task InvokeAsync(BrowserOptions options, CancellationToken token = default)
    {
        _options = options;

        using (var form = _formFactory.Invoke())
        {
            using (var webView = new WebView2()
            {

                form.FormClosed += (o, e) =>

                        };

                        signal.Release();
                        form.Close();
                    }
                };

                try
                {
                    form.Controls.Add(webView);
                    webView.Show();

                    form.Show();

                    // Initialization
                    await webView.EnsureCoreWebView2Async(null);

                    // 删除现有的 Cookie，这样以前的登录就不会被记住, 以免影响测试, 反之去掉这行,就可以保持登录
                    //webView.CoreWebView2.CookieManager.DeleteAllCookies();

                    // Navigate
                    webView.CoreWebView2.Navigate(_options.StartUrl);

                    await signal.WaitAsync();
                }
                finally
                {
                    form.Hide();
                    webView.Hide();
                }

                return browserResult;
            }
        }
    }

    private bool IsBrowserNavigatingToRedirectUri(Uri uri)
    {
