如何解决AEM6.1中的“org.apache.sling.servlets.post.impl.operations.ModifyOperation无法创建资源”错误？

Question

我得到这个错误在我们的生产环境 -

但是我们没有“/content/mywebsite/en/autodiscover/autodiscover.xml”或“/内容/ mywebsite/EN /自动发现”在我们的仓库中。不知道它从哪里获取此网址。

如何在不访问此特定URL的情况下对其进行调试。谢谢！

Answer 1

看你的堆栈跟踪，有一点突出的是：

/content/mywebsite/

这看起来像在其中可以从您的域名重定向请求的调度程序文件（某些默认配置wwww.example.com ）发布到发布商的默认（假定）内容结构。

或者，它可能是您发布商的吊索贴图。

因此，根据评论中建议的解释，某些电子邮件客户端（如Outlook）尝试使用与您的域（user@example.com）相对应的电子邮件地址自动注册用户。这将启动自动发现POST请求。

这是企业环境中大多数电子邮件客户端的普通设置，所以这不是问题。这里值得考虑的问题有：

您的发布商正在接受POST来自匿名用户的请求。这必须由调度员或发布者阻止。

Adob​​e有很多关于调度程序设置和发布者安全性的文档来解决此问题。总结一下，您需要禁用发布服务器上的匿名用户的写入权限，并配置分派器以阻止任意路径上的POST请求。

调试

您可以轻松地使用curl模拟相同的POST请求重现当地环境这个问题。 .xml文件不允许在引发此错误的/ content节点下。

Answer 2

正如在另一个答案中提到的，您不需要调试此问题，因为它是网络和安全配置问题而不是AEM问题。您必须：

• 在您的发布者和调度员处安全匿名发布。
• 修复您的吊绳映射或调度程序配置（如果有）来照顾mywebsite内容路径解析。

另一种可能性是，一些内部企业网络配置错误，并且SMTP自动发现现在被重定向到您的发布者而不是您通常的邮件服务器。
