你能不载webcomponents从其他领域？
我得到一个功能强大的错误在火狐/linux。
我加入这个服务，但仍然不能负荷：
add_header Access-Control-Allow-Origin *;
<html lang="en">
<head>
<meta charset="utf-8" />
<script type="module" src="//briskreader.com/components/feed-list.js"></script>
</head>
<body>
<feed-list topic="bitcoin"></feed-list>
</body>
</html>
这里是错误：
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://briskreader.com/components/feed-list.js. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).
Loading module from “http://briskreader.com/components/feed-list.js” was blocked because of a disallowed MIME type (“text/html”).
test.html
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://briskreader.com/components/feed-list.js. (Reason: CORS request did not succeed).
这里的头briskreader.com:
