身份服务器空 'License' 参数

Question

我正在开发一个使用 IdentityServer 4 和 .Net 5 的应用程序我基于 'with React.js' 和个人身份验证模板创建了项目。

我正在尝试为身份服务器配置密钥管理...

services.AddIdentityServer()
                .AddApiAuthorization<ApplicationUser, ApplicationDbContext>()
                .AddSigningKeyManagement()
                .PersistKeysWith<ApplicationDbContext>();

public ApplicationDbContext(
            DbContextOptions options,
            IOptions<OperationalStoreOptions> operationalStoreOptions) : base(options, operationalStoreOptions)
        {
        }
        public DbSet<SerializedKey> SerializedKeys { get; set; }

        public async Task<IEnumerable<SerializedKey>> LoadKeysAsync()
        {
            return await SerializedKeys.ToListAsync();
        }

        public async Task StoreKeyAsync(SerializedKey key)
        {
            await SerializedKeys.AddAsync(key);
            await this.SaveChangesAsync();
        }

        public async Task DeleteKeyAsync(string id)
        {
            SerializedKey key = SerializedKeys.First(x => x.Id == id);
            SerializedKeys.Remove(key);
            await this.SaveChangesAsync();
        }

我能够成功运行迁移并创建 table -

但是如果我尝试运行应用程序，我会在启动时遇到异常

我不确定如何提供该许可参数，非常感谢任何帮助。

谢谢！

你可以在 youtube 上看 video tutorial。时间戳 09:19.
AddSigningKeyManagement 有重载，您可以在其中传递从 https://www.identityserver.com/products/KeyManagement/ 收到的 Licensee 和 License。它是付费功能。接下来两个是免费的。
出于开发目的，您可以使用 AddDeveloperSigningCredential 方法；
出于生产目的，我建议您通过 AddSigningCredential 方法使用 self-signed x509 证书。示例代码：

if (certificateConfiguration.UseSigningCertificatePfxFile)
{
    if (string.IsNullOrWhiteSpace(certificateConfiguration.SigningCertificatePfxFilePath))
    {
        throw new Exception(SigningCertificatePathIsNotSpecified);
    }

    if (File.Exists(certificateConfiguration.SigningCertificatePfxFilePath))
    {

        try
        {
            builder.AddSigningCredential(new X509Certificate2(certificateConfiguration.SigningCertificatePfxFilePath, certificateConfiguration.SigningCertificatePfxFilePassword));
        }
        catch (Exception e)
        {
            throw new Exception("There was an error adding the key file - during the creation of the signing key", e);
        }
    }
    else
    {
        throw new Exception($"Signing key file: {certificateConfiguration.SigningCertificatePfxFilePath} not found");
    }
}
else if (certificateConfiguration.UseTemporarySigningKeyForDevelopment)
{
    builder.AddDeveloperSigningCredential();
}
