asp.net-core - ASOS - 当具有单独的授权服务器和资源服务器时， token 验证不起作用

Question

我正在尝试通过此 post 使用 ASOS 来实现 OpenID Connect 服务器(资源所有者密码凭据授予) . 当我在一个应用程序中同时拥有授权服务器和资源服务器时，一切正常。但是当我将它们拆分到两个应用程序(但在一台机器上)时，资源服务器无法验证 token 并返回访问 token 无效。

我下载了 AspNet.Security.OAuth.Validation 的源代码来调查这个问题，它返回 null here

这是授权服务器的一些日志:

1) 我的资源服务器出了什么问题？

2)如何在不同的机器上配置资源服务器(特别是 token 签名/检查和加密/解密)？

Answer 1

How to configure the resource server on different machine (especially token signing/checking and encryption/decryption)?

您需要确保 key 环(包含由 ASP.NET Core 数据保护派生以创建加密和验证 key 的主 key )正确同步并由您的授权服务器和资源服务器共享.此处描述了该过程:https://learn.microsoft.com/en-us/aspnet/core/security/data-protection/configuration/overview .

这是一个如何使用共享文件夹完成的示例:

public void ConfigureServices(IServiceCollection services)
{
    services.AddDataProtection()
        .PersistKeysToFileSystem(new DirectoryInfo(@"\\server\share\directory\"))
}

您还需要配置这两个应用程序以使用相同的“应用程序鉴别器”:

public void ConfigureServices(IServiceCollection services)
{
    services.AddDataProtection()
        .PersistKeysToFileSystem(new DirectoryInfo(@"\\server\share\directory\"))
        .SetApplicationName("Your application name");
}
