需求：C#客户端程序, 窗口里嵌入一个web网页，可通过URL跳转的那种。并且，需要将登录的身份验证信息（token）设置到请求头里。

核心代码如下：

// 打开按钮的点击事件
private void openBtn_Click(object sender, EventArgs e)
{
    string urlText = this.urlTextBox.Text;
    Uri uri = new Uri(urlText);

    this.webView.Source = uri;
}

// webview2 控件的 CoreWebView2InitializationCompleted 事件
private void webView_CoreWebView2InitializationCompleted(object sender, CoreWebView2InitializationCompletedEventArgs e)
{
    
    webView.CoreWebView2.AddWebResourceRequestedFilter("*", CoreWebView2WebResourceContext.All);
    webView.CoreWebView2.Settings.AreDefaultContextMenusEnabled = false;
    webView.CoreWebView2.Settings.AreBrowserAcceleratorKeysEnabled = false;
    //webView.CoreWebView2.WebResourceRequested += CoreWebView2_WebResourceRequested;
    webView.CoreWebView2.WebResourceRequested += CoreWebView2_WebResourceRequested;
}

// 设置请求头信息
private void CoreWebView2_WebResourceRequested(object sender, CoreWebView2WebResourceRequestedEventArgs e)
{
    e.Request.Headers.SetHeader("Authorization", "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJzdWIiOiIyMDA2MTcyMDQyNDMxMzE0MTM4IiwiaWF0IjoxNzE4MjYxODczLCJleHAiOjE3MTgzMjE4NzN9.AUmUMQX2R-GgkQg_IvKphfgVagl-z96DwhdAh7z-9TZ5-y4cP_9YrsGlTGHF21nvm95BMjFdbpDDdST6w_3ivA");
}

实现的效果：
