获取DiscoveryClient失败,并显示"颁发者名称与权限不匹配"

Question

使用IdentityModel执行GET时,我得到以下错误DiscoveryClient,如下所示:

var discoveryResponse = await DiscoveryClient.GetAsync("https://localhost/IdentityServer");

颁发者名称与权限不匹配:https:// localhost/identityserver

目标URL是在使用IdentityServer4启用的IIS上运行的ASP.NET Core Web应用程序.客户端应用程序是在同一台计算机上运行的经典ASP.NET Web应用程序.

显然,GET确实设法从IdentityServer检索值,如以下内容所示discoveryResponse.Raw:

{
  "issuer": "https://localhost/identityserver",
  "jwks_uri": "https://localhost/IdentityServer/.well-known/openid-configuration/jwks",
  "authorization_endpoint": "https://localhost/IdentityServer/connect/authorize",
  "token_endpoint": "https://localhost/IdentityServer/connect/token",
  "userinfo_endpoint": "https://localhost/IdentityServer/connect/userinfo",
  "end_session_endpoint": "https://localhost/IdentityServer/connect/endsession",
  "check_session_iframe": "https://localhost/IdentityServer/connect/checksession",
  "revocation_endpoint": "https://localhost/IdentityServer/connect/revocation",
  "introspection_endpoint": "https://localhost/IdentityServer/connect/introspect",

}

Answer 1

authority:https:// localhost/IdentityServer issuer:https:// localhost/identityserver

它们不匹配 - 它区分大小写.

Answer 2

如果您无法更改服务器代码以适应策略，您可以更改策略设置以允许名称不匹配。

例如，我试图用DiscoveryClient对Azure的REST API，而且issuer是https://sts.windows.net/{{ tenant_id }}同时端点的所有下手https://login.microsoft.com/{{ tenant_id }}。

只需将字段ValidateIssuerName和设置ValidateEndpoints为 false。

var tenant_id = "8481D2AC-893F-4454-8A3B-A0297D301278"; // Made up for this example
var authority = $"https://login.microsoftonline.com/{tenant_id}";
DiscoveryClient discoveryClient = new DiscoveryClient(authority);

// Accept the configuration even if the issuer and endpoints don't match
discoveryClient.Policy.ValidateIssuerName = false;
discoveryClient.Policy.ValidateEndpoints = false;

var discoResponse = await discoveryClient.GetAsync();

稍后编辑

自从发布此消息以来，DiscoveryClient该类已被弃用。

这是新的调用语法：

var client = new HttpClient();
var discoResponse = await client.GetDiscoveryDocumentAsync(
    new DiscoveryDocumentRequest
    {
        Address = authority,
        Policy =
        {
            ValidateIssuerName = false,
            ValidateEndpoints = false,
        },
    }
);
