从span标签android jsoup获取数据

Question

我想从URL示例中获取一个图像博客头像：https://soundcloud.com/topsify

<span style="background-image: url(&quot;https://i1.sndcdn.com/avatars-000132054558-5ra8gl-t500x500.jpg&quot;); width: 200px; height: 200px; opacity: 1;" class="sc-artwork sc-artwork-placeholder-8 image__rounded image__full g-opacity-transition" aria-label="Topsify’s avatar" aria-role="img"></span>

我试图得到：

document = Jsoup.connect("https://soundcloud.com/topsify").get();
Elements imgElement = document.select("span[style*=background-image:]");

但它还是空的。请支持获取头像url：https://i1.sndcdn.com/avatars-000132054558-5ra8gl-t500x500.jpg谢谢

尝试使用userAgentString。下面的代码只是示例，您可以使用element.select（）。

检查页面的查看源。这是img标签，不是span标签

    String url = "https://soundcloud.com/topsify";
    Response res = Jsoup.connect(url).userAgent("Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko").timeout(3000).execute();
    Document document = res.parse();
    //get <img> tags
    for (Element img : document.getElementsByTag("img")) {
    Elements avatars;
    //get src attribute value whose has "avatars"
    if((avatars = img.getElementsByAttributeValueMatching("src", "avatars")) !=null){
     System.out.println(avatars.attr("src"));
    }             
 }
