我需要将当前页面路径设置为canocical
标记。不幸的是我在这里有一些错误。在这段代码上:
<%
ResourceResolver resolver = slingRequest.getResourceResolver();
Externalizer externalizer = resolver.adaptTo(Externalizer.class);
String canonUrl = externalizer.publishLink(resourceResolver, "http", currentPage.getPath());
%>
<link rel="canonical" href="${canonUrl}" />
我有这个输出:
<link rel="canonical" href="" />
出了什么问题。但是如果我像这样设置canonical
标签:
<link rel="canonical" href="${currentPage.path}" />
我有这个输出:
<link rel="canonical" href="/content/example/eu/germany/de_de/about.html" />
那几乎没问题。而现在,我只需要添加域名( http://example.com/content/example/eu/germany/de_de/about.html )。但是如何在没有硬编码的情况下做到这一点?方法在本地化页面上也可以正常工作。

您需要在Externalizer Service中配置域。
转到OSGi控制台(/ system / console / components)并查找com.day.cq.commons.impl.ExternalizerImpl
。然后单击configure并为本地,作者和发布添加行。例如:
local http://localhost:4502
author http://author.example.com
publish http://publish.domain.com

你可以通过jstl -
从bean类中读取主机private String getHost(HttpServletRequest request)
{
String xHost = request.getHeader("x-forwarded-host");
if(xHost == null)
{
String host = request.getHeader("Host");
if(host == null)
{
String urlS = request.getRequestURL().toString();
try
{
return (new URI(urlS)).getAuthority();
}
catch(URISyntaxException use)
{
return (new
StringBuilder()).append(request.getServerName())
.append(":").append(request.getServerPort()).toString();
}
} else
{
return host;
}
}
if(xHost.indexOf(',') >= 0)
xHost = xHost.substring(xHost.indexOf(','));
return xHost.trim();
}
