从网络电台获取艺术家和标题 [英] Fetch artist and title from net radio

问题描述

Hi,
I am trying to fetch the artist and title from a website streaming live music.

http://radioglobus.dk/netradio/?autoplay=true%22

http://radioglobus.dk/netradio/?autoplay=true%22

If I hit F12 (Developer Tools) in Edge I can see the artist in <span class="nowPlayingArtist"></span><br />
And the title in <span class="nowPlayingTitle"></span><br />

But the above function returns everything except the artist and the title.

What do I need to fetch the artist and title?

Thank in advance

我的尝试：

What I have tried:

Public Async Function GetIt(ByVal uri As String) As Task(Of String)
    Dim Content As String = Await wvRadio.InvokeScriptAsync("eval", New String() {"document.documentElement.outerHTML;"})
    Await Task.Delay(2000)
    If Content.Contains("playingnow") Then
        Debug.WriteLine(Content)
    End If
    Return ""
End Function

var url = "http://radioglobus.dk/netradio/?autoplay=true%22";
var web = new HtmlWeb();
var doc = web.Load(url);
var nodes = doc.DocumentNode.SelectNodes("//span");
var node = nodes.FirstOrDefault(x => x.Attributes.Any(a => a.Name == "class" && a.Value == "nowPlayingTitle"));
if (node != null)
{
    Console.WriteLine(node.InnerHtml);
}

node.InnerHtml是歌曲名称。

这个例子是在C＃中，但你可以很容易地重写它VB Net。

"node.InnerHtml" is the song name.
This example is in C# but you could easily rewrite it in VB Net.
