aem - CQ/AEM Dispatcher 不刷新二进制文件

Question

我们的应用程序从遗留系统导入二进制文件(主要是 PDF)，并将它们与一些元数据一起存储在页面上。

如果有更改，页面会自动激活。我们在复制日志中看到复制事件，并且在调度程序上也记录了一个无效事件。但是没有驱逐条目，旧的二进制文件仍然被缓存。

我们在二进制文件的这些容器页面旁边还有 HTML 页面，它们按预期工作。这是成功的 html 和不成功的 PDF 的两个日志条目:

不行

本例中的 PDF 存储在 jcr:content 节点正下方的名为“下载”的节点中。它的 html 容器从不直接调用，这在调度程序上不可用。所以用户直接请求文件:/content/offering/s2p/en/offerings/documents/Swiss_Mandate_Line/Review/as2p_vvm_ch_gl_fix_chf__pdf/jcr%3acontent/download/file.res/as2p_vvm_ch_gl_fix_chf_.pdf

在 dispatcher.any 中，我们在激活时刷新所有 html 页面，但不刷新二进制文件。为了测试，我们添加了一个 allow *.pdf 但这无论如何都没有帮助。

/invalidate
{
/0000
  {
  /glob "*"
  /type "deny"
  }
/0001
  {
  /glob "*.html"
  /type "allow"
  }
}

在我看来，invalidate 调用应该只删除整个文件夹:/content/offering/s2p/en/offerings/documents/Swiss_Mandate_Line/Review/as2p_vvm_ch_gl_fix_chf__pdf

知道为什么我们的二进制文件没有被刷新吗？

更新:在另一篇文章中提到了 dispatcher.any 中的 statfileslevel 属性。在我们的环境中，这被注释掉了。难道这可能是问题所在。可悲的是，我不完全理解这应该如何工作。级别是指从wwwroot还是从激活的页面？

Answer 1

看起来你的调度程序刷新问题是文件提供的路径使用 jcr%3acontent 而它应该使用 _jcr_content。

Dispatcher flushing 删除正在刷新的路径下的文件夹_jcr_content。它不会删除 jcr%3acontent(url 解码为 jcr:content)。因此，您应该改为使用此 URL 提供 pdf:/content/offering/s2p/en/offerings/documents/Swiss_Mandate_Line/Review/as2p_vvm_ch_gl_fix_chf__pdf/_jcr_content/download/file.res/as2p_vvm_ch_gl_fix_chf_.pdf

这会将 pdf 文件缓存在:{CACHEROOT}/content/offering/s2p/en/offerings/documents/Swiss_Mandate_Line/Review/as2p_vvm_ch_gl_fix_chf__pdf/_jcr_content/download/file.res/as2p_vvm_ch_gl_fix_chf_.pdf

然后当这个路径被刷新时它会删除刷新路径下的子目录_jcr_content/content/offering/s2p/en/offerings/documents/Swiss_Mandate_Line/Review/as2p_vvm_ch_gl_fix_chf__pdf

更详细地说，当您对上述路径发出刷新请求时，将删除以下文件和目录:

• /content/offering/s2p/en/offerings/documents/Swiss_Mandate_Line/Review/as2p_vvm_ch_gl_fix_chf__pdf.* 其中 * 是通配符
• /content/offering/s2p/en/offerings/documents/Swiss_Mandate_Line/Review/as2p_vvm_ch_gl_fix_chf__pdf/_jcr_content
