如何解決AEM6.1中的「org.apache.sling.servlets.post.impl.operations.ModifyOperation無法創建資源」錯誤？

Question

我得到這個錯誤在我們的生產環境 -

但是我們沒有「/content/mywebsite/en/autodiscover/autodiscover.xml」或「/內容/ mywebsite/EN /自動發現」在我們的倉庫中。不知道它從哪裏獲取此網址。

如何在不訪問此特定URL的情況下對其進行調試。謝謝！

Answer 1

看你的堆棧跟蹤，有一點突出的是：

/content/mywebsite/

這看起來像在其中可以從您的域名重定向請求的調度程序文件（某些默認配置wwww.example.com ）發佈到發佈商的默認（假定）內容結構。

或者，它可能是您發佈商的吊索貼圖。

因此，根據評論中建議的解釋，某些電子郵件客戶端（如Outlook）嘗試使用與您的域（user@example.com）相對應的電子郵件地址自動註冊用戶。這將啓動自動發現POST請求。

這是企業環境中大多數電子郵件客戶端的普通設置，所以這不是問題。這裏值得考慮的問題有：

您的發佈商正在接受POST來自匿名用戶的請求。這必須由調度員或發佈者阻止。

Adob​​e有很多關於調度程序設置和發佈者安全性的文檔來解決此問題。總結一下，您需要禁用發佈服務器上的匿名用戶的寫入權限，並配置分派器以阻止任意路徑上的POST請求。

調試

您可以輕鬆地使用curl模擬相同的POST請求重現當地環境這個問題。 .xml文件不允許在引發此錯誤的/ content節點下。

Answer 2

正如在另一個答案中提到的，您不需要調試此問題，因爲它是網絡和安全配置問題而不是AEM問題。您必須：

• 在您的發佈者和調度員處安全匿名發佈。
• 修復您的吊繩映射或調度程序配置（如果有）來照顧mywebsite內容路徑解析。

另一種可能性是，一些內部企業網絡配置錯誤，並且SMTP自動發現現在被重定向到您的發佈者而不是您通常的郵件服務器。
