rel=无推荐人

<a>、<area> 和 <form> 元素的 rel 属性的 noreferrer 关键字指示浏览器在导航到目标资源时省略 Referer 标头，否则不会泄漏引用者信息，此外，其行为就像 noopener 关键字也一样 指定的。

¥The noreferrer keyword for the rel attribute of the <a>, <area>, and <form> elements instructs the browser, when navigating to the target resource, to omit the Referer header and otherwise leak no referrer information — and additionally to behave as if the noopener keyword were also specified.
