JWT身份验证错误的参数

Question

我正在学习如何向WebApi添加JWT令牌身份验证。到目前为止，我在Startup.cs内所做的操作：

using Microsoft.AspNetCore.Authentication;
using Microsoft.AspNetCore.Authentication.JwtBearer;
..
..
 public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
   if (env.IsDevelopment())
   {
    app.UseDeveloperExceptionPage();
   }

   app.UseJwtBearerAuthentication(new JwtBearerOptions
   {
     AutomaticAuthenticate = true,

     TokenValidationParameters = new TokenValidationParameters
     {
        ValidIssuer = "http://localhost:Port",
        ValidateAudience = false,
        IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("testPass"))
     }
   });

   app.UseMvc();
}

但是我遇到类似这样的错误：

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 JwtBearerAppBuilderExtensions.UseJwtBearerAuthentication(IApplicationBuilder, JwtBearerOptions)' is obsolete: 'See https://go.microsoft.com/fwlink/?linkid=845470

和

2. JwtBearerOptions' does not contain a definition for 'AutomaticAuthenticate'

Answer 1

您可以在ConfigureServices的{​​{1}}方法中进行此操作。

StartUp.cs

然后使用 public void ConfigureServices(IServiceCollection services) { services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme).AddJwtBearer(o => { o.TokenValidationParameters = new TokenValidationParameters { ValidateIssuer = true, ValidateAudience = false, ValidateLifetime = false, ValidateIssuerSigningKey = true, ValidIssuer = "http://localhost:Port", IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("YourKey")) }; }); // other configuration... } 方法：

Configure

Answer 2

尝试在ConfigureService中而不是在Configure中进行操作，尝试类似

services.AddAuthentication(x =>
        {
            x.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
            x.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
        })
        .AddJwtBearer(x =>
        {
            x.RequireHttpsMetadata = false;
            x.SaveToken = true;
            x.TokenValidationParameters = new TokenValidationParameters
            {
                ValidateIssuerSigningKey = true,
                IssuerSigningKey = new SymmetricSecurityKey(key),
                ValidateIssuer = false,
                ValidateAudience = false
            };
        });

它将起作用！
