c# - c# HttpRequestMessage Authorization 使用 IdentityServer 返回 401

Question

我有一个用于演示目的的 IdentityServer4 服务器（我已按照 IdentityServer4 文档中的入门指南进行操作）。我能够从中获取令牌，并且在使用 Postman 时，我能够使用此令牌从受保护的资源中获取信息。

但是当我尝试从我的 c# 代码中使用这个令牌时，我得到一个 401 响应（Postman 中的相同令牌工作正常）。我在代码中设置请求的方式如下：

httpRequestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", "{token string}");

我知道服务器接受令牌。我添加了一个控制台来将令牌写入到服务器的不同请求中，并将其与我使用 Postman 得到的进行比较。这是我的输出：

调用api/values端点时，我看到请求被令牌接受。然后它调用.well-known/openid-configuration，然后调用.well-known/openid-configuration/jwks，然后再调用 ，api/values但这次使用的是空的授权令牌。

如果我将此与 Postman 调用进行比较，那么在对api/values端点的第二次调用中，它确实具有授权令牌。

我的请求设置中缺少什么？有人可以解释在服务器端进行的额外调用以及为什么调用api/values两次？

您需要在 API 项目中配置 IdentityServer EndPoint，如下所示

public void ConfigureServices(IServiceCollection services)
{

    services.AddMvcCore()
    .AddAuthorization()
    .AddJsonFormatters();

    services.AddAuthentication("Bearer")
    .AddIdentityServerAuthentication(options =>
    {
        options.Authority = "http://localhost:5000";//IdentityServer4 Endpoint
        options.RequireHttpsMetadata = false;

        options.ApiName = "api1";//Name of resource
    });

}
