c# – 在UWP中设置自定义WebView标头

a. I need the headers for each request including javascript redirected URLs in web View.

b. This didn’t resolve my issue as after setting the headers the OnWebViewNavigationStarting method is called multiple times and App crashes automatically with System.StackOverflowException error

这是因为如果我们在NavigationStarting事件中进行导航,将会发生无限导航.我们应该通过将WebViewNavigationStartingEventArgs.Cancel属性设置为true来取消此事件的处理程序中的导航.

我们需要仔细添加/删除NavigationStarting事件的处理程序.

代码示例：

private void NavigateWithHeader(Uri uri)
    {
        var requestMsg = new Windows.Web.Http.HttpRequestMessage(HttpMethod.Get,uri);
        requestMsg.Headers.Add("User-Name","Franklin Chen");
        wb.NavigateWithHttpRequestMessage(requestMsg);

        wb.NavigationStarting += Wb_NavigationStarting;
    }

    private void Button_Click(object sender,RoutedEventArgs e)
    {
        NavigateWithHeader(new Uri("http://openszone.com/RedirectPage.html"));
    }

    private void Wb_NavigationStarting(WebView sender,WebViewNavigationStartingEventArgs args)
    {
        wb.NavigationStarting -= Wb_NavigationStarting;
        args.Cancel = true;//cancel navigation in a handler for this event by setting the WebViewNavigationStartingEventArgs.Cancel property to true
        NavigateWithHeader(args.Uri);
    }
