Google AppEngine：dev服務器 - 拒絕訪問「datastore-indexes-auto.xml」的內容

Question

當我嘗試在本地數據存儲區查看器中查看任何實體時，在Windows 7 Pro 64位上運行的Google AppEngine dev服務器會引發異常， http：// localhost：8080/_ah/admin/datastore「 實體列表顯示得很好，我的應用程序能夠將實體添加到數據存儲。問題是什麼？這與安全經理有關嗎？

你試過

• 停止你的開發應用服務器
• 刪除「數據存儲的索引，auto.xml」文件
• 重新使用本地您的開發應用服務器
• 數據存儲查看器？
