Question about ASP.NET Core 3 Identity / Identity Server / SPA support for Resource Owner Password Grant Type

Question

As per Authentication and authorization for SPAs, I have created a new SPA with support for API authorization. You can view this on GitHub.

In order to support integration tests, I have added a new client (see appsettings.json) that is allowed the resource owner password grant type:

"SecureSpa.IntegrationTests": {
  "Profile": "IdentityServerSPA",
  "AllowedGrantTypes": [ "password" ],
  "ClientSecrets": [ { "Value": "K7gNU3sdo+OL0wNhqoVWhr3g6s1xYv72ol/pe/Unols=" } ],
  "AllowedScopes": [ "SecureSpaAPI", "openid", "profile" ]
}

Then within WeatherForecastControllerTests.cs, I attempt to request the token as follows:

"SecureSpa.IntegrationTests": {
  "Profile": "IdentityServerSPA",
  "AllowedGrantTypes": [ "password" ],
  "ClientSecrets": [ { "Value": "K7gNU3sdo+OL0wNhqoVWhr3g6s1xYv72ol/pe/Unols=" } ],
  "AllowedScopes": [ "SecureSpaAPI", "openid", "profile" ]
}

When running the test, I've tried many different combinations, however the results are usually the same (unauthorized_client). This is the relevant log output from Identity Server:

  }
}

  "RemoteIpAddress": "unknown"
}
Microsoft.AspNetCore.Hosting.Diagnostics: Information: Request finished in 212.96790000000001ms 400 application/json; charset=UTF-8

Is this approach supported? If not, is there an alternative approach that can be used to get the token in order to write integration tests? I'm planning to set up test users along with the test client so that I can test lots of different behaviours.

我继续研究这个问题，发现当配置文件设置为 IdentityServerSPA 时，没有添加允许的密码授予类型。我看不到通过 appsettings 添加没有配置文件的客户端的方法，所以我从 appsettings 中删除了配置并使用这种方法创建了客户端：

services.AddIdentityServer()
    //.AddApiAuthorization<ApplicationUser, ApplicationDbContext>();
    .AddApiAuthorization<ApplicationUser, ApplicationDbContext>(options =>
    {
        options.Clients.AddIdentityServerSPA("SecureSpa", builder =>
        {
            builder.WithRedirectUri("https://localhost:44307/authentication/login-callback");
            builder.WithLogoutRedirectUri("https://localhost:44307/authentication/logout-callback");
        });
        options.Clients.Add(new Client
        {
            ClientId = "SecureSpa.IntegrationTests",
            AllowedGrantTypes = { GrantType.ResourceOwnerPassword },
            ClientSecrets = { new Secret("secret".Sha256()) },
            AllowedScopes = { "SecureSpaAPI", "openid", "profile" }
        });
    });

有了这个，我的测试现在可以运行了。你可以在这里看到最终的解决方案；https://github.com/JasonGT/SecureSpa/。

一切正常，但是DefaultClientRequestParametersProvider. 请参阅“GetClientParameters”方法 - 如果指定的客户端没有关联的配置文件，InvalidOperationException则抛出 。
