如何从.Net core 2.0中的HttpContext获取访问令牌

提问于

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 .

Old Method .Net core 1.1

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

    return View();
}

Method .Net core 2.0

这不起作用因为上下文未注册 .

[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

我尝试注册它，但这也不起作用

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

在startup.cs中

services.TryAddSingleton<HttpContext, HttpContext>();

Update:

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也不会感到惊讶，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 Configure

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?}");
        });

    .Net core 2.1 访问JWT bearer tocken

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

    它最终成为配置问题 . AddAuthentication和AddOpenIdConnect之间需要有一个链接，以便将cookie读入 Headers .

    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");
            });

    Controller

    [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：我最终把它从这个项目中挖出来Startup.cs

    Startup.cs

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

    Controller.cs构造函数

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



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

    return View();
}

    这应该工作

    从Azharuddin回答一点点变化

    在Startup方法中注册服务实例

    public void ConfigureServices(IServiceCollection services)
{

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

    并在控制器中注入依赖项

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

    并在您的操作中检索访问令牌

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

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

    真的，谢谢，这是完美的！

    我有这项工作，但我们的天蓝色租户专注于权威 . 只需用您的租户名称替换******即可 .

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

    您也可以使用租户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";
