Question

我试图通过它的Open Graph api从我的Rails应用程序向Facebook提供信息，但我无法在双引号内使用＃{}进行插入。当我查看输出html时，它就像下面所示，而不是插入Rails值。

<meta property="og:title" content="#{[@miniature.name.html_safe, @user.name].join(' by ')}"/>
<meta property="og:type" content="website" />
<meta property="og:url" content="#{request.original_url}"/>
<meta property="og:image" content="#{@collection.photo.url(:thumb)}"/>

Answer 1

尝试：

<meta property="og:title" content="<%= [@miniature.name.html_safe, @user.name].join(' by ') %>"/>
<meta property="og:type" content="website" />
<meta property="og:url" content="<%= request.original_url %>"/>
<meta property="og:image" content="<%= @collection.photo.url(:thumb) %>"/>

Answer 2

您需要使用＆lt;％=％＆gt;标记而不是＃{}。

<meta property="og:title" content="<%= [@miniature.name.html_safe, @user.name].join(' by ') %>"/>
<meta property="og:type" content="website" />
<meta property="og:url" content="<%= request.original_url %>"/>
<meta property="og:image" content="<%= @collection.photo.url(:thumb) %>"/>
