Question

我正在尝试将项目从.Net核心1.1升级到.Net核心2.0，有很多重大变化。我目前遇到的一个问题是HttpContext.Authentication现在已经过时了。

我一直在试图弄清楚如何获取当前请求的Access令牌。我需要调用另一个需要持有令牌的API。

旧方法.Net核心1.1

[Authorize]
public async Task<IActionResult> ClientUpdate(ClientModel client)
{
    var accessToken = await HttpContext.Authentication.GetTokenAsync("access_token");

    return View();
}

方法.Net core 2.0

由于上下文未注册，因此无效。

[Authorize]
public async Task<IActionResult> ClientUpdate(ClientModel client)
{
    var accessToken = await context.HttpContext.GetTokenAsync("access_token"); 

    return View();
}

无法解析“Microsoft.AspNetCore.Http.HttpContext”类型的服务

我尝试注册但不起作用

public ConsoleController(IOptions<ServiceSettings> serviceSettings, HttpContext context)

在startup.cs中

services.TryAddSingleton<HttpContext, HttpContext>();

更新

返回null

var accessToken = await HttpContext.GetTokenAsync("access_token");

Startup.cs ConfigureServices

如果在初创公司中有什么东西我不会感到惊讶，因为这里也有很多重大变化。

services.Configure<ServiceSettings>(Configuration.GetSection("ServiceSettings"));
//services.TryAddSingleton<HttpContext, HttpContext>();
services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();
services.AddMvc();
services.AddAuthentication(options =>
            {

                options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
                options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
            })
            .AddCookie()
            .AddOpenIdConnect(options =>
            {
                options.Authority = "http://localhost:5000";
                options.ClientId = "testclient";
                options.ClientSecret = "secret";
                options.ResponseType = "code id_token";
                options.RequireHttpsMetadata = false;
                options.GetClaimsFromUserInfoEndpoint = true;
            });

Startup.cs配置

loggerFactory.AddDebug();

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseBrowserLink();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();

        app.UseStaticFiles();
        app.UseAuthentication();

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });

Answer 1

.Net core 2.1 访问JWT承载者令牌

var accesToken = Request.Headers["Authorization"];

Answer 2

最终成为配置问题。 AddAuthentication和AddOpenIdConnect之间需要有一个链接，以便将cookie读入标题。

services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();

services.AddAuthentication(options =>
            {
                options.DefaultScheme = "Cookies";
                options.DefaultChallengeScheme = "oidc";
            })
            .AddCookie("Cookies")
            .AddOpenIdConnect("oidc", options =>
            {
                options.SignInScheme = "Cookies";

                options.Authority = "http://localhost:5000";
                options.RequireHttpsMetadata = false;

                options.ClientId = "testclient";
                options.ClientSecret = "secret";
                options.ResponseType = "code id_token";
                options.SaveTokens = true;
                options.GetClaimsFromUserInfoEndpoint = true;

                options.Scope.Add("testapi");
                options.Scope.Add("offline_access");
            });

<强>控制器

    [Authorize]
    public async Task<IActionResult> Index()
    {
        var accessToken = await HttpContext.GetTokenAsync("access_token");
        return View();
    }

现在填充了访问令牌。

注意：我最终将其从这个项目中挖掘出来Startup.cs

Answer 3

如果您想要纯令牌，则可以在.net core 3.1中提供帮助

var _bearer_token = Request.Headers[HeaderNames.Authorization].ToString().Replace("Bearer ", "");

，请记住，您需要使用来添加

using Microsoft.Net.Http.Headers;

Answer 4

Azharuddin的回答有点变化

在启动方法中注册服务实例，如

public void ConfigureServices(IServiceCollection services)
{

 services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
 ...
}

并在控制器中注入依赖项，如

private IHttpContextAccessor _httpContextAccessor;
public ClientController(IHttpContextAccessor httpContextAccessor)
{
     _httpContextAccessor = httpContextAccessor;
}

并在您的操作中检索访问令牌，如

[Authorize]
public async Task<IActionResult> ClientUpdate(ClientModel client)
{
    var accessToken = _httpContextAccessor.HttpContext.Request.Headers["Authorization"];

    ..........//Some other code
    return View();
}

Answer 5

Startup.cs

DELIMITER $$
DROP PROCEDURE IF EXISTS check_status$$
CREATE PROCEDURE check_status()

 BEGIN
     DECLARE dd DATE;
     DECLARE bDone INT;
     DECLARE Count INT;
     DEClARE my_status CURSOR FOR SELECT dates FROM t_date;
     DECLARE CONTINUE HANDLER FOR NOT FOUND SET bDone = 1;

 OPEN my_status;
    SET bDone = 0;

    REPEAT
        FETCH my_status INTO dd;

        IF (dd < DATE(NOW()))

                UPDATE t_date SET (status_number) VALUES (1);

        END IF;

    UNTIL bDone END REPEAT;

 CLOSE my_status;


 END$$

DELIMITER ;

Controller.cs构造函数

 public void ConfigureServices(IServiceCollection services)
    {
    ...
     services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
     ...
    }

这应该有效

Answer 6

非常感谢，这太完美了！

我有这项工作，但是有了我们的青睐租户的授权。只需用您的租户名称替换******。

options.Authority = "https://login.microsoftonline.com/******.onmicrosoft.com";

您还可以使用租户ID。只需在https://login.microsoftonline.com/

之后插入您的租户ID

options.Authority = "https://login.microsoftonline.com/be0be093-****-****-****-5626e83beefc";

Answer 7

您需要指定外部架构来检索令牌。

var accessToken = await HttpContext.GetTokenAsync(IdentityConstants.ExternalScheme, "access_token");

如何从.Net core 2.0中的HttpContext获取访问令牌
