Question

我想抓取网页并提取嵌入在网页中的视频网址。我首先使用了Inspect工具，可以很容易地看到嵌入式链接，如下图所示：

还有目标<video>标签：

<video class="jw-video jw-reset" tabindex="-1" disableremoteplayback="" webkit-playsinline="" playsinline="" preload="metadata" src="https://lh3.googleusercontent.com/YYxKbKt3Apa8A2LkHKBJ7Fx6GU_iCIjEeGyyPJm_Ll-9hO4K8fDZV1pAbYprwpRhS5yFanf7=m18?title=[CayPhim.Net]-Bay-Vien-Ngoc-Rong-Sieu-Cap-tap-6.[360p]"></video>

然后我尝试使用View Page Source工具并搜索了链接，但找不到它。相反，我发现了一些javascript代码，这些代码似乎用于动态地（在页面加载时）将链接添加到页面并添加到页面：

<div id="switchserver" style="height:100%;">
  <div id="phim_html5" style="height:100%;">
    <div class="loading"></div>
  </div>
  <script>$(document).ready(function () {
    $.ajax({
      url: "http://player.cayphim.net/jwplayer7/index_googima.php",
      type: "GET",
      cache: false,
      data: {
        "url": "8ce46ffa35805780571877c8ae5808f6a5e8898ebf9d294326735716694ccb4279505da51df9678cc8601a390a422d5e639449ec90332ee518e06f1dd579606d106f292d49bb38d9b2e80d0ee965a5c0e2911922e48ac972c521c4236512d356681404472b2cb39d9fff915bb4da21c8315d3fd6fc6cb0d2ed27183598661d40",
        "name": "QmF5IFZpZW4gTmdvYyBSb25nIFNpZXUgQ2FwIHRhcCA2",
        "sub": ""
      },
      success: function (msg) {
        $("#phim_html5").html(msg);
      }, error: function () {
        $("#phim_html5").html("<div class='player-error'>Server quá tải. Vui lòng chọn server khác bên dưới...</div>");
      },
    });
  });
  </script>
  <img style="display: none" src="http://image.cayphim.net/1553256337-lSC0nSX6Wj9dlOXfK29gK2iwoKF9D0p4YwnxYgmyCwmyBfJ29eW1wKpPetD3BkBKF9D0p4MsZPPjEReTD0UVY0K4YvoGKF9D0p42wODHaQKFo5pGMVmG9XmN05lP80DksxCQaHXKF9D0p4MMJwwhnyohFxsEYKF9D0p4wRJH5xYk1eXEr9mETjpng" />
</div>

现在，我使用Advanced REST Client向GET发出了http://player.cayphim.net/jwplayer7/index_googima.php代码中指定的参数，对javascript发出了<div id="playerjw7">Trình duyệt của bạn không hỗ trợ xem phim bằng Player HTML5. Vui lòng cài đặt Chrome hoặc Firefox</div>请求，但是我收到了包含以下内容的响应：

    var connString = "mongodb+srv";
    var client = new MongoClient(connString);
    var database = client.GetDatabase("Base");
    var collection = database.GetCollection<UsuariosAcessos>("collection"); //Here you put you Model

    var filter = Builders<UsuariosAcessos>.Filter.Eq(x => x.PartnerId, cliente) 
        & Builders<UsuariosAcessos>.Filter.Eq(x => x.CD_CLIENTE, codCond);   

    var lista = collection.Aggregate().Match(filter).Project(x => new UsuariosAcessos
    {
          CD_CLIENTE = x.CD_CLIENTE,
          ID_ACESSO = x.ID_ACESSO,
          CD_ACESSO = x.CD_ACESSO,
          NOME = x.NOME,
          NU_TELEFONE = x.NU_TELEFONE,
          EMAIL = x.EMAIL,
          NU_KIPER_RF = x.NU_KIPER_RF,
          NU_KIPER_TAG = x.NU_KIPER_TAG,
          FG_KIPER_MOBILE = x.FG_KIPER_MOBILE,
          KEY_HASH = x.KEY_HASH
  }).ToList();

是的，它是越南语，但这表示“您的浏览器不支持Video Player HTML5。请安装Chrome或Firefox”。

我如何以编程方式抓取并提取嵌入的视频网址？
