我发现某个地方可能是跨浏览器问题所以我放下了以下代码但仍无法正常工作：

<?xml version="1.0" encoding="utf-8"?>
<cross-domain-policy><allow-access-from domain="*"/></cross-domain-policy>
<VAST version="2.0">

网址示例：

Answer 1

你是对的。这是跨域问题。以下字符串： <cross-domain-policy><allow-access-from domain="*"/></cross-domain-policy>应位于crossdomain.xml文件中，该文件应存在于放置VAST的服务器根目录中。它是flash安全策略所必需的。

因此，您应该将crossdomain.xml放在服务器的根目录中，或者使用上面的字符串更新它。

VAST：无法从服务器请求广告。原因：错误＃2048
