c# – 在控制台应用程序中忽略Web浏览器SSL安全警报

要处理证书错误,您需要实现IHttpSecurity服务并根据请求传递给Web浏览器. webbrowser通过ActiveX主机上实现的IServiceProvider查询主机服务.假设您使用的是Windows窗体,则需要执行以下操作：

>从WebBrowser派生一个类
>创建一个从WebBrowser.WebBrowserSite派生的嵌套类(您可以从嵌套类派生的唯一方法)
>覆盖CreateWebBrowserSiteBase并返回webbrowser站点的新实例.
>在webbrowser站点上实现IServiceProvider
>实现IServiceProvider.QueryService,以便在请求IHttpSecurity服务时返回IHttpSecurity imepleemntation
>处理IHttpSecurity.OnSecurityProblem并返回S_OK
>在表单中使用新的webbrowser

示例代码：

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void webBrowser1_DocumentCompleted(object sender,WebBrowserDocumentCompletedEventArgs e)
    {
        if (e.Url.ToString() == "about:blank")
        {
            //create a certificate mismatch
            webBrowser1.Navigate("https://74.125.225.229");
        }
    }
}
