Kubernetes + Redis：防伪令牌无法解密

Question

我在 Kubernetes 上的 .net core 3.0 上使用 Redis 数据库进行数据保护，但仍然出现以下错误。有什么想法吗？

fail: Microsoft.AspNetCore.Antiforgery.DefaultAntiforgery[7] An exception was thrown while deserializing the token. Microsoft.AspNetCore.Antiforgery.AntiforgeryValidationException: The antiforgery token could not be decrypted. ---> System.Security.Cryptography.CryptographicException: The key {ffb146a1-0e5e-4f96-8566-425f7c2eb99a} was not found in the key ring. at Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingBasedDataProtector.UnprotectCore(Byte[] protectedData, Boolean allowOperationsOnRevokedKeys, UnprotectStatus& status) at Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingBasedDataProtector.DangerousUnprotect(Byte[] protectedData, Boolean ignoreRevocationErrors, Boolean& requiresMigration, Boolean& wasRevoked) at Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingBasedDataProtector.Unprotect(Byte[] protectedData) at Microsoft.AspNetCore.Antiforgery.DefaultAntiforgeryTokenSerializer.Deserialize(String serializedToken) --- End of inner exception stack trace --- at Microsoft.AspNetCore.Antiforgery.DefaultAntiforgeryTokenSerializer.Deserialize(String serializedToken) at Microsoft.AspNetCore.Antiforgery.DefaultAntiforgery.GetCookieTokenDoesNotThrow(HttpContext httpContext)

var redis = ConnectionMultiplexer.Connect(Environment.GetEnvironmentVariable("REDIS_CONNSTR"));
services.AddDataProtection().PersistKeysToStackExchangeRedis(redis, "DataProtection-Keys");
services.AddMvc(options =>
{
    options.Filters.Add(new AutoValidateAntiforgeryTokenAttribute());
});

根据下面文章中的文档，需要设置应用程序名称。

services.AddDataProtection()
    .PersistKeysToStackExchangeRedis(redis, "DataProtection-Keys")
    .SetApplicationName("product");

By default, the Data Protection system isolates apps from one another based on their content root paths, even if they're sharing the same physical key repository. This prevents the apps from understanding each other's protected payloads.

To share protected payloads among apps:

• Configure SetApplicationName in each app with the same value.

关于这一点的进一步说明。如果您收到 400 Bad Request 并在同一解决方案中使用 API，那么我建议您查看 IgnoreAntiforgeryToken 属性来装饰 CSRF 不适用的方法。
