通过使用OpenIddict登录外部提供程序获取令牌

标签: authentication oauth-2.0 asp.net-core google-authentication openiddict

我有一个带有ASP.NET Core的API,它将由本机移动应用程序(目前是UWP,Android)使用,我正在尝试实现一种方式,客户端可以注册并使用用户名/密码和外部登录谷歌和Facebook等提供商。现在我正在使用openIddict而我的ExternalProviderCallback必须返回我认为当前返回cookie的本地令牌! (我已从某处复制了大部分代码)而且似乎不是AuthorizationCodeFlow,我认为这是正确的方法!

现在这是我的启动课

public class Startup
{
    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
            .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);

        if (env.IsDevelopment())
        {
            builder.AddUserSecrets();
        }
        builder.AddEnvironmentVariables();
        Configuration = builder.Build();
    }

    public IConfigurationRoot Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddSingleton<IConfiguration>(c => Configuration);
        services.AddEntityFramework();
        services.AddIdentity<ApplicationUser, IdentityRole>(config =>

                        context.Response.StatusCode = 403;
                    return Task.CompletedTask;
                }

        services.AddOpenIddict()
            .AddEntityFrameworkCoreStores<ApplicationDbContext>()
            .UseJsonWebTokens()
            .AddMvcBinders()

        });
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env,
        ILoggerFactory loggerFactory, DbSeeder dbSeeder)

        app.UseIdentity();
        app.UseOAuthValidation();

        app.UseGoogleAuthentication(new GoogleOptions()
        {
            AutomaticAuthenticate = true,

        app.UseOpenIddict();

        app.UseMvcWithDefaultRoute();
        try
        {
            dbSeeder.SeedAsync().Wait();
        }
        catch (AggregateException ex)
        {
            throw new Exception(ex.ToString());
        }
    }
}

这里是AccountController,它正在做外部提供者工作:

    #region Authorization code, implicit and implicit flows

    // Note: to support interactive flows like the code flow,

    [Authorize, HttpGet("authorize")]
    public IActionResult Authorize(OpenIdConnectRequest request)
    {
        return Ok();
    }

    #endregion
}

这就是我发送请求的方式:

https://localhost:44380/api/Accounts/ExternalLogin/Google?returnUrl=https://localhost:44380

成功返回到AccountsController中的ExternalLoginCallback Action但没有JWT令牌像普通的PasswordGrantFlow一样发回给用户。

如果可以在这里发送代码,请不要将我的代码重定向到其他地方,因为我对服务器端全新,并且我之前已经完成了我的搜索。

尝试authorization code flow sample

如果您希望立即将用户重定向到指定的社交提供商而不是将其返回到登录页面,则可以调整授权端点:

    if (!User.Identity.IsAuthenticated)
    {
        // Resolve the optional provider name from the authorization request.
        // If no provider is specified, call Challenge() to redirect the user
        // to the login page defined in the ASP.NET Core Identity options.
        var provider = (string) request.GetParameter("identity_provider");
        if (string.IsNullOrEmpty(provider))
