WebView2 控件（基于 Microsoft Edge (Chromium) 的嵌入式浏览器控件），获取网页加载资源

await webView.EnsureCoreWebView2Async();

// 订阅Web资源请求事件
webView.CoreWebView2.WebResourceRequested += (sender, args) => 
{
    string url = args.Request.Uri;
    string method = args.Request.Method;
    
    // 获取资源类型（通过Content-Type或文件扩展名）
    string resourceType = "Unknown";
    if (args.Response != null)
    {
        string contentType = args.Response.Headers.GetHeader("Content-Type")?.ToLower();
        
        if (contentType.Contains("text/css")) resourceType = "CSS";
        else if (contentType.Contains("javascript")) resourceType = "JS";
        else if (contentType.Contains("image/")) resourceType = "Image";
        // 其他类型判断...
    }
    
    // 输出资源信息
    Debug.WriteLine($"Resource: {url}, Type: {resourceType}, Method: {method}");
};

await webView.EnsureCoreWebView2Async();

// 启用网络跟踪
await webView.CoreWebView2.CallDevToolsProtocolMethodAsync("Network.enable", "{}");

// 创建资源列表
List<WebResource> resourceList = new List<WebResource>();

// 订阅网络响应事件
var receiver = webView.CoreWebView2.GetDevToolsProtocolEventReceiver("Network.responseReceived");
receiver.DevToolsProtocolEventReceived += (sender, e) => 
{
    dynamic response = Newtonsoft.Json.JsonConvert.DeserializeObject(e.ParameterObjectAsJson);
    
    string url = response.response.url;
    string mimeType = response.response.mimeType;
    int status = response.response.status;
    
    // 添加到资源列表
    resourceList.Add(new WebResource
    {
        Url = url,
        MimeType = mimeType,
        StatusCode = status,
        ResourceType = response.type.ToString()
    });
    
    // 实时显示
    Debug.WriteLine($"Loaded: {url} ({mimeType})");
};

// 定义资源类
public class WebResource

    public string Url { get; set; }
    public string MimeType { get; set; }
    public int StatusCode { get; set; }
    public string ResourceType { get; set; }
