在生产环境中IdentityServer4无法工作

asp.netreactjsidentityserver4
22
我在使用IdentityServer4和React启动项目时，使用的是ASP.NET Core 3.0预览版4。一切正常，直到我构建解决方案并在命令提示符中使用dotnet命令运行应用程序时，它告诉我未指定密钥类型。
我尝试过各种生成证书的指南，因为我在.NET中没有任何关于证书的经验。我提到这点是因为问题可能是由于生成证书的不正确方式引起的。
我还尝试将密钥类型添加到Appsettings.json中，但我不知道类型是什么。我已经通过谷歌搜索了整天，寻找有关如何配置IdentityServer4以进行部署的文档，但是似乎没有人遇到此问题，也没有任何帮助生成正确证书的需求。
只要我指定它是开发环境，我就可以在Visual Studio中运行应用程序。
当我切换到生产环境或者构建解决方案并从命令提示符中运行时，会出现以下的堆栈跟踪：

如果有人能够帮我脱离这个困境，我将非常感激。

请发布您用于添加签名凭据的代码。 - Vidmantas Blazevicius
我已经发布了一个答案，解释了我是如何解决这个问题的。再次感谢您的帮助。 :-) - Antheus_S

如果您想使用*.pfx

"Key": {
  "Type": "File",
  "FilePath": "certificate.pfx",
  "Password": "password:!"
}

如果你遇到了这个错误，请阅读此线程 WindowsCryptographicException: Keyset does not exist

internal.cryptography.cryptothrowhelper+windowscryptographicexception keyset does not exist

给未来的读者，将.pfx文件放在您的项目根目录中，您可以按照这里的方式创建它，然后将其包含在您的构建文件夹中，例如这样。 - olfek

你从哪里了解到这个设置的？它对于开发环境非常有帮助，我在任何官方的 IS 文档中都没有看到过。 - Dan

所以我成功解决了我的问题，使用了这份文档：https://learn.microsoft.com/en-us/aspnet/core/security/authentication/identity-api-authorization?view=aspnetcore-3.0#example-deploy-to-azure-websites 我需要在 appsettings.json 属性中启用 "Copy if newer"，以便它能够被复制到构建文件夹中。
我还在 appsettings.json 文件中添加了以下内容：
"IdentityServer": {
"Clients": {
  "Client": {
    "Profile": "IdentityServerSPA"
  }
},
"Key": {
  "Type": "Store",
  "StoreName": "My",
  "StoreLocation": "LocalMachine",
  "Name": "CN=SigningCertificate"
}
}

现在指定了Key.Type，这意味着我们现在只需将以下内容添加到startup.cs中：

// Configure IdentityServer4
var identityBuilder = services.AddIdentityServer();
identityBuilder.AddApiAuthorization<ApplicationUser, ApplicationDbContext>();

if (!Environment.IsDevelopment())
     identityBuilder.AddSigningCredentials();

我仍然不明白为什么其他人没有遇到这个问题，因为我找不到任何关于这个问题的其他帖子，而且常规方法似乎对其他人都有效。唯一的缺点是现在我需要在机器上安装证书，而不是将其作为文件获取。

我尝试使用Docker运行您的答案，但是我得到了以下日志：Application startup exception: System.Security.Cryptography.CryptographicException: Unix LocalMachine X509Store is limited to the Root and CertificateAuthority stores. ---> System.PlatformNotSupportedException: Unix LocalMachine X509Store is limited to the Root and CertificateAuthority stores. - Shady Mohamed Sherif
当你说你必须启用“仅在更新时复制”时，你是在哪里进行的操作？ - user
if (!Environment.IsDevelopment()) identityBuilder.AddSigningCredentials(); is unecessary as identityBuilder.AddApiAuthorization<ApplicationUser, ApplicationDbContext>(); already makes a call to AddSigningCredentials() - Richard
如果我在控制台应用程序中读取我的证书主题，我会得到CN=app.mydomainname.com，OU=PositiveSSL，OU=Domain Control Validated。如果我将其原封不动地用作Web应用程序中的Key -> Name设置，我会得到问题中提到的错误。有什么解决方法吗？使用证书文件可以解决问题。但是对于生产环境来说，这是一种安全风险。 - frosty
@frosty，我得到的主题名称是“CN=website.com, OU=Domain Control Validated”。IS无法使用此找到证书。你找到了解决方法吗？ - tmutton

这是我在Docker for Blazor WebAssembly中解决它的方法。我的答案主要基于this thread。请注意，尽管它可以工作，但可能不适用于生产环境，也不安全。我对IdentityServer的了解很少。

appsettings.json:

"IdentityServer": {
    //[...]

    "Key": {
      "Type": "File",
      "FilePath": "/path_to_certificate_here/server.pfx",
      "Password": "password_specified_later"
    }
  }

FilePath 是您实际放置证书的位置（在本答案的下一步中生成）。Password 在生成证书时进行配置。

生成证书：

源。这也可能不是生产就绪的。

$ openssl genrsa 2048 > server_private.pem
$ openssl req -x509 -days 1000 -new -key server_private.pem -out server_public.pem
$ openssl pkcs12 -export -in server_public.pem -inkey server_private.pem -out server.pfx

请记住，证书将会在第二个命令中的 -days 属性过期。

使用Docker

有一些答案建议将证书包含在 build 文件夹中或与项目源代码一起保存。我个人认为这不是一个好主意。我在我的服务器上手动生成证书，并在分离的文件夹中创建 Docker 卷，然后将其指向放置证书的文件夹。

除了已接受的答案外，如果有人想使用AsymmetricSecurityKey创建自己的SigningCredentials，而不是在appsettings.json中使用“Key”配置，则以下内容也可以解决问题。
  1. 首先在xml文件中定义RSA参数或存储在应用程序资源文件中：例如（工作示例），
<RSAKeyValue>
    <Modulus>9+hZCiZrVpqe1t+Q4HOfzrmmkNkNPurX3btOva9Hdx1lIKV7ndeVGCq71plXhW78krXdcDSSeOEVf8W51/Qq0ai8Rg9P1XIcedVgIj7MiHZ+k/rcnq1Y9yg6d1DHXtlAJLasvhCc3o+9inXh2DAzllIxyy4FabS51dRyWDBMA2LS8kS3o5UdcVQYoY+B/9d8qVHmlbQNuao3NL/UqVo6UKnGidSjTQMyPkPJEmpul9C3Cn8Tm7zqKidk2A/obU5bmBFfivhPGoFnahYMs635LpitEPdJGQCfzcmLyE9y23cPyPzowkB/zsONCgWoxglst95vKRWgyXgBXAiSbKtaFQ==</Modulus>

</RSAKeyValue>

然后，我们可以使用RSA辅助方法读取参数，创建AsymmetricSecurityKey。我为我的项目创建了以下辅助类：
using System.Security.Cryptography;
public static class MyKeyStore
    {
        public static AsymmetricSecurityKey Key;

        static MyKeyStore()
        {
            var props = RSA.Create();
            props.FromXmlString(Resources.RsaProps);
            Key = new RsaSecurityKey(props);
        }
    }

修改 Startup.cs 类，并使用上述辅助类生成 SigningCredentials。例如：
// configure IDS
 services.AddIdentityServer(options =>
            {
                // ...

            }).AddApiAuthorization<ApplicationUser, ApplicationDbContext>
            (options => { options.SigningCredential = new SigningCredentials(MyKeyStore.Key, SecurityAlgorithms.RsaSha512);});

请注意，如果您想了解一个工作示例，我最近在一个演示项目中使用了它，该项目目前正在Azure上运行。这里是启动文件，这里是完整的项目。
