没有配置身份验证处理程序来对方案进行身份验证：Microsoft.AspNet.Identity.External

Question

我正在使用 asp.net 5 rc2 构建一个 api。我正在尝试实现 openiddict-core，为本地帐户找到 here，我还希望允许用户使用外部登录，例如 google。

我已经全部设置好了，但是当我尝试实现 google 身份验证时，我调用了这个代码

var info = await _signInManager.GetExternalLoginInfoAsync();

我在标题中收到错误消息。

在客户端上，我使用的是 Satellizer，找到了 here，它负责打开 google 提示窗口并将回调发送到我的 AuthController Google 方法，这是您在其他 mvc6 示例中看到的正常 ChallengeResult 代码。

我已经编写了代码来手动获取用户详细信息并且可以正常工作，但我想我会改用已经构建的 signInManager，而不是复制轮子...

我可能没有正确设置，因为所有示例似乎都使用 cookie，我猜这是因为它们是 mvc6 Web 应用程序，而不是 api。我不想使用 cookie，但这可能是我的问题。

现在是一些代码。

startup.cs

public void ConfigureServices(IServiceCollection services)
{
    // Add MVC services to the services container.
    services.AddMvc();

    services.AddEntityFramework()
        .AddSqlServer()
        .AddDbContext<ApplicationDbContext>(options =>
        options.UseSqlServer(_configuration["Data:DefaultConnection:ConnectionString"]));

    services.AddIdentity<ApplicationUser, IdentityRole>()
        .AddEntityFrameworkStores<ApplicationDbContext>()
        .AddDefaultTokenProviders()
        .AddOpenIddict(); // Add the OpenIddict services after registering the Identity services.
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    // use jwt bearer authentication
    app.UseJwtBearerAuthentication(options =>
    {
        options.AutomaticAuthenticate = true;
        options.AutomaticChallenge = true;
        options.RequireHttpsMetadata = false;
        options.Audience = "http://localhost:5000/";
        options.Authority = "http://localhost:5000/";
    });

    // Add all the external providers you need before registering OpenIddict:
    app.UseGoogleAuthentication(options =>
    {
        options.AutomaticAuthenticate = true;
        //options.AutomaticChallenge = true;
        options.ClientId = "XXX";
        options.ClientSecret = "XXX";
    });
    //app.UseFacebookAuthentication();

    app.UseOpenIddict();

    // Enable all static file middleware
    app.UseStaticFiles();

    // Enable Mvc for view controller, and 
    // default all routes to the Home controller
    app.UseMvc(options =>
    {
        options.MapRoute(
            name: "default",
            template: "{*url}",
            defaults: new { controller = "Home", action = "Index" });
    });
}

AuthController.cs

public class AuthController : Controller
{
    private UserManager<ApplicationUser> _userManager;
    private SignInManager<ApplicationUser> _signInManager;
    private ApplicationDbContext _applicationDbContext;

    public AuthController(
        UserManager<ApplicationUser> userManager,
        SignInManager<ApplicationUser> signInManager,
        ApplicationDbContext applicationDbContext)
    {
        _userManager = userManager;
        _signInManager = signInManager;
        _applicationDbContext = applicationDbContext;
    }

    [HttpPost("google")]
    public async Task<IActionResult> GoogleAsync([FromBody] ExternalLoginModel model)
    {
        // THIS IS WHERE ERROR OCCURS
        var info = await _signInManager.GetExternalLoginInfoAsync();


        return Ok();
    }
}

ExternalLoginModel.cs

public class ExternalLoginModel
{
    public string Code { get; set; }

    public string ClientId { get; set; }

    public string RedirectUri { get; set; }
}

您是否尝试在注册 GoogleAuthentication 中间件之前通过添加 app.UseIdentity(); 来注册 Identity 中间件？
