无法使用 XMLHTTP 请求获取文档内容

Question

我正在尝试使用 XMLHTTP 从 https://www.businesstimes.com.sg/keywords/singapore-parliament 获取新闻文章列表，但它似乎返回一个仅包含没有内容的脚本的文档。

我尝试了一个基本请求：

Private Sub Test()
    Dim xmlhttp As MSXML2.XMLHTTP60
    Set xmlhttp = New MSXML2.XMLHTTP60
    
    xmlhttp.Open "GET", "https://www.businesstimes.com.sg/keywords/singapore-parliament", False
    xmlhttp.Send
           
    Set xmlhttp = Nothing
End Sub

它返回一个包含一堆除此之外的缩小脚本的文档：

<script>
    (function() {
      'use strict';
      var afterReadyCbCalled = false;
      var originalHeaders = ["X-Host", "www.businesstimes.com.sg","X-EC-Hot-Hash", "7790000207959645976","x-ec-pop", "sgb","X-Forwarded-For", "103.252.200.88, 165.225.112.130, 152.195.199.174, 35.201.102.132","X-EC-Session-ID", "12399570086198404337867903748881746029","Accept", "*/*","Accept-Language", "en-US,en-GB;q=0.8,en;q=0.5,ja;q=0.3","True-Client-IP", "165.225.112.130","X-Cloud-Trace-Context", "ff9cf2795015e71e68e65cd11ad81a87/6844774677298190324","X-EC-Uuid", "12399570086198404337867903748881746029","X-Forwarded-Proto", "https","UA-CPU", "AMD64",];
      var originalBody = "";
      function afterReadyCb() {
        if (afterReadyCbCalled) return;
        afterReadyCbCalled = true;
        var xhr = new XMLHttpRequest();
        xhr.onload = function() {
          var isValid = xhr.getResponseHeader("ISTL-INFINITE-LOOP");
          if (isValid != null && isValid != '') return;
          var a = xhr.getResponseHeader("ISTL-REDIRECT-TO");
          if (a != null && a != '') {
            location.replace(a);
          } else {
            if (window.history != null && typeof history.replaceState === 'function') {
              var responseURL = xhr.responseURL != null ? xhr.responseURL : xhr.getResponseHeader("ISTL-RESPONSE-URL");
              if (responseURL != null && responseURL != '') {
                history.replaceState(null, '', responseURL);
              }
            }
            // DO NOT INLINE. There is a bug specific to IE/Edge.
            var responseText = xhr.responseText;
            document.open();
            document.write(responseText);
            document.close();
          }
        };
        xhr.open("get", location.href, true);
        for (var i = 0; i < originalHeaders.length; i += 2) {
          var headerName = originalHeaders[i];
          try {
            xhr.setRequestHeader(headerName, originalHeaders[i + 1]);
          } catch (e) {}
        }
        xhr.setRequestHeader("ISTL-INFINITE-LOOP", '1');
        xhr.send(originalBody);
        var evt = document.createEvent('Event');
        evt.initEvent('BJNyvohAx', true, true);
        dispatchEvent(evt);
      }
      addEventListener('afterReady', afterReadyCb, false);
      setTimeout(afterReadyCb, 200);
    }());
  </script>

我还尝试了 .setRequestHeader 与脚本中声明的 originalHeaders 和 .setRequestHeader "ISTL-INFINITE-LOOP", "1" 中的所有值，但是却得到了 403 Forbidden 错误。

谁能告诉我我缺少什么才能获取文档内容？ （如果有可能的话）

提前致谢！
