The antiforgery token could not be decrypted.

.net core 3.1 在Linux上發布的時候遇到如下問題：

Microsoft.AspNetCore.Antiforgery.DefaultAntiforgery[7]

An exception was thrown while deserializing the token.
Microsoft.AspNetCore.Antiforgery.AntiforgeryValidationException: The antiforgery token could not be decrypted.

 

是因為 .net croe 的coookie的生成驗證要使用MecachineKey找不到，或者分布式部署時兩個程序讀取的Meachine Key不一致造成的，
這個時候需要我們設置同一個MeacheineKey
