「未經授權：您提出的請求需要驗證（HTTP 401）」在Fiware Horizo​​n上

Question

我是FIWARE的新手。在我的Ubuntu 16.04上，我設置了Fiware's KeyRock，它是OpenStack Keystone Identity Management和Horizo​​n Dashboard的組合。我已經使用this指南來設置一切。

安裝Keystone（這是一個RESTful API）後，我用curl發送HTTP請求，一切工作正常，即我可以使用curl在keystone服務器上運行these命令。

然而，當我使用位於openstack_dashboard目錄與參考Django項目在同一臺服務器上運行的地平線：

sudo tools/with_venv.sh python manage.py runserver 0.0.0.0:8000，

地平線服務器沒有任何錯誤開始，但是當我通過瀏覽器訪問它，我得到以下錯誤：

A server error occured. Please contact the administrator 

上的梯形服務器控制檯，我得到以下錯誤：

我送通過瀏覽器，但梯形服務器接收POST請求的GET請求，因爲表明了其控制檯輸出。我不明白這是爲什麼。

看起來Horizo​​n服務器無法驗證憑據。

對於Fiware，如果文件local_settings.py（位於/horizon/openstack_dashboard/local/目錄中）未正確配置，您將在Horizo​​n服務器上發生此錯誤。在此文件中，有一個名爲IDM_USER_CREDENTIALS的字典，您需要爲填充Keystone數據庫時創建的管理員配置文件設置密碼。它也在您提供的link中給出。嘗試更改密碼並查看它是否有效。
