客户端无法获取带有身份的 cookie

Client can't get cookies with Identity

我正在使用 ASP.NET 核心和 Angular 编写 SPA 应用程序。我正在使用 CORS 在前端和后端之间进行通信。我发现登录后无法获得授权,并且客户端没有cookie。卡了2天了,求大神指教

startup.cs中,我有:

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddCors(...)      
        services.AddDbContext<TaskMatrixContext>(...);
        services.AddControllers(...)
        services.Configure<IdentityOptions>(options =>
        {...}); 
        services.AddIdentity<AppUser,IdentityRole().
                 AddEntityFrameworkStores<TaskMatrixContext>();
        services.AddAuthentication().AddCookie();
        services.ConfigureApplicationCookie(options =>
        {...});
        services.AddAuthorization(options =>
        {...});  
         ...
    } 

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        ...
        app.UseRouting();
        app.UseCors("AllowMyOrigin");
        app.UseAuthentication();
        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
        });
    }

这是我的 AccountController:

[HttpPost("/login")]
public async Task<ActionResult<LoginDto>> Login(LoginDto model)
{
    if (ModelState.IsValid)
    {
        var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, true);

        if (result.Succeeded)
        {
            model.IsLoggedIn = true;
        }

        if (result.IsLockedOut)
        {
            model.IsLockedOut = true;
            model.RedirectUrl = "/account/lockedout";
        }
    }

    return model;
}

在我的前端:

login(dto:LoginInput):Observable<LoginResult> {
    return this.http.post<LoginResult>
                (this.baseUrl+'/login',dto).pipe(
                    tap(...)
                );
}

您应该使用 withCredentials 选项:

https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/withCredentials

在您的前端:

login(dto:LoginInput):Observable<LoginResult> {
    return this.http.post<LoginResult>
                (this.baseUrl+'/login',dto,{withCredentials: true}).pipe(
                    tap(...)
                );
}

对于需要身份验证 cookie 的每个请求都应执行相同的操作

又研究了几天,发现不能用Identity Core在REST中实现认证Api。我们应该使用 JWT 来生成令牌并验证它。推荐的前端教程是: https://jasonwatmore.com/post/2019/10/14/aspnet-core-3-simple-api-for-authentication-registration-and-user-management 对于后端: https://dev.to/moe23/asp-net-core-5-rest-api-authentication-with-jwt-step-by-step-140d
