NET Core 2.0中缺少IServiceCollection的扩展方法AddJwtBearerAuthentication() [英] Missing extension method AddJwtBearerAuthentication() for IServiceCollection in .NET Core 2.0

问题描述

我已使用

I have updated my project from Core 1.1 to Core 2.0 using instructions from https://blogs.msdn.microsoft.com/webdev/2017/08/14/announcing-asp-net-core-2-0/ (updated target framework to .NET Core 2.0 and used metapackage Microsoft.AspNetCore.All). I have updated all possible nuget packages to latest versions as well.

在.NET Core 1.1中，我通过以下方式添加了JWT承载身份验证:

In .NET Core 1.1 i was adding JWT Bearer Authentication this way:

app.UseJwtBearerAuthentication(); // from Startup.Configure()

按照 http://www.talkingdotnet .com/whats-new-in-asp-net-core-2-0/对于Core 2.0，新方法是调用:

As per http://www.talkingdotnet.com/whats-new-in-asp-net-core-2-0/ for Core 2.0 the new way is to call:

services.AddJwtBearerAuthentication(); // from Startup.ConfigureServices()

但是没有方法 AddJwtBearerAuthentication().已安装软件包Microsoft.AspNetCore.Authentication.JwtBearer 2.0.0.

But the method AddJwtBearerAuthentication() is absent. The package Microsoft.AspNetCore.Authentication.JwtBearer 2.0.0 is installed.

新的空Core 2.0项目(带有JwtBearer程序包)也没有针对IServiceCollection的扩展方法AddJwtBearerAuthentication().

New empty Core 2.0 projects (with JwtBearer package) are also does not have extension method AddJwtBearerAuthentication() for IServiceCollection.

旧方法 app.UseJwtBearerAuthentication()根本无法编译:

Error   CS0619  'JwtBearerAppBuilderExtensions.UseJwtBearerAuthentication(IApplicationBuilder, JwtBearerOptions)' is obsolete: 'See https://go.microsoft.com/fwlink/?linkid=845470'

请帮助.

推荐答案

在ConfigureServices中，使用以下代码来配置JWTBearer身份验证:

In ConfigureServices use the following code to configure JWTBearer Authentication:

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddAuthentication(o =>
        {
            o.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
            o.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
        }).AddJwtBearer(o =>
        {
            o.Authority = "https://localhost:54302";
            o.Audience = "your-api-id";
            o.RequireHttpsMetadata = false;
        });

        services.AddMvc();
    }

在UseMvc()之前的Configure中，添加UseAuthentication():

app.UseAuthentication();

app.UseStaticFiles();

app.UseMvc();

有关详细示例，请参见: https://github.com/aspnet/Security/blob/dev/samples/JwtBearerSample/Startup.cs#L51
