我使用SignalR 2.2.0和MVC 4。當我打開我的Chrome瀏覽器網頁,我收到一個錯誤在控制檯:SignalR - 指定的解密密鑰無效的十六進制字符
http://localhost:8180/signalr/negotiate?clientProtocol=1.5&connectionData=%5B%7B%22name%22%3A%22chathub%22%7D%5D&_=1467627883530 500 (Internal Server Error)
經進一步檢查使用菲德勒我可以查看堆棧跟蹤:

從我收集的,SignalR使用機器的關鍵部分進行加密/解密。
這是機器的關鍵看起來像什麼:
<machineKey decryptionKey="5E329ED7DE2786FCD906E717C97A09BE26B3564BBE0A2B28,IsolateApps" validationKey="A64F709FB47B282CB8331205BC423D63450B4FFC92FE06EC1E00B3AE8B5B1F529A5CD1064F66C08545FC13B013F84153598B29213D5494DD5EC348B537A51DAE,IsolateApps"/>
我猜它看到「IsolateApps」在decryptionKey /的validationKey和拋出異常(「...無效的十六進制字符」)。
如果我從密鑰中刪除「IsolateApps」,我無法再登錄,因爲我使用的是FormsAuthentication,後者又使用密鑰來加密/解密。因此,刪除「IsolateApps」似乎不是一個解決方案。
PS。我使用的代碼是this教程。 我已經看過this answer但它不能解決問題。我也嘗試將compatibilityMode="Framework20SP1"
添加到機器密鑰中,但這也不起作用。
有沒有辦法解決這個問題,而無需從網絡配置中的鍵刪除「IsolateApps」值?
刪除IsolateApps爲我工作,所以謝謝。不過,在進行配置更改後,我仍然回落到SSE。 :( –
