将JWT身份验证实现从.net核心2传输到asp.net Web API 2 [英] transfer JWT Authentication implementation from .net core 2 to asp.net web api 2
问题描述
我在 .net core 2应用程序中实现了 JWT身份验证,效果很好.
i have implementation of JWT Authentication in .net core 2 application, it work fine.
我想在 asp.net Web api 2 应用程序中使用此实现和结构,但出现错误
i want to use this implementation and structure in asp.net web api 2 application but i get error
我的结构:
JwtTokenBuilder类:
using System;
using System.Collections.Generic;
using Microsoft.IdentityModel.Tokens;
using System.IdentityModel.Tokens.Jwt;
using System.Security.Claims;
using System.Linq;
namespace solution.Authentication
{
public sealed class JwtTokenBuilder
{
private SecurityKey securityKey = null;
private string subject = "";
private string issuer = "";
private string audience = "";
private Dictionary<string, string> claims = new Dictionary<string, string>();
private DateTime expireTime = DateTime.UtcNow.AddMinutes(30);
public JwtTokenBuilder AddSecurityKey(SecurityKey securityKey)
{
this.securityKey = securityKey;
return this;
}
public JwtTokenBuilder AddSubject(string subject)
{
this.subject = subject;
return this;
}
public JwtTokenBuilder AddIssuer(string issuer)
{
this.issuer = issuer;
return this;
}
public JwtTokenBuilder AddAudience(string audience)
{
this.audience = audience;
return this;
}
public JwtTokenBuilder AddClaim(string type, string value)
{
this.claims.Add(type, value);
return this;
}
public JwtTokenBuilder AddClaims(Dictionary<string, string> claims)
{
this.claims.Union(claims);
return this;
}
public JwtTokenBuilder AddExpiry(DateTime expireTime)
{
this.expireTime = expireTime;
return this;
}
public JwtToken Build()
{
EnsureArguments();
var claims = new List<Claim>
{
new Claim(JwtRegisteredClaimNames.Sub, this.subject),
new Claim(JwtRegisteredClaimNames.Jti, Guid.NewGuid().ToString())
}
.Union(this.claims.Select(item => new Claim(item.Key, item.Value)));
var token = new JwtSecurityToken(
issuer: this.issuer,
audience: this.audience,
claims: claims,
expires: this.expireTime,
signingCredentials: new SigningCredentials(
this.securityKey,
SecurityAlgorithms.HmacSha256));
return new JwtToken(token);
}
#region " private "
private void EnsureArguments()
{
if (this.securityKey == null)
throw new ArgumentNullException("Security Key");
if (string.IsNullOrEmpty(this.subject))
throw new ArgumentNullException("Subject");
if (string.IsNullOrEmpty(this.issuer))
throw new ArgumentNullException("Issuer");
if (string.IsNullOrEmpty(this.audience))
throw new ArgumentNullException("Audience");
}
#endregion
}
}
令牌对象:
using System;
using System.IdentityModel.Tokens.Jwt;
namespace solution.Authentication
{
public sealed class JwtToken
{
private JwtSecurityToken token;
internal JwtToken(JwtSecurityToken token)
{
this.token = token;
}
public DateTime ValidTo => token.ValidTo;
public string access_token => new JwtSecurityTokenHandler().WriteToken(this.token);
}
}
安全密钥类:
using Microsoft.IdentityModel.Tokens;
using System.Text;
namespace solution.Authentication
{
public static class JwtSecurityKey
{
public static SymmetricSecurityKey Create(string secret)
{
return new SymmetricSecurityKey(Encoding.ASCII.GetBytes(secret));
}
}
}
我的令牌控制器方法,用于 generate 并返回 token :
my token controller methode for generate and return token :
private JwtToken getToken(User user)
{
DateTime startTime = DateTime.Now;
DateTime expireTime = DateTime.Now.AddMinutes(60);
var token = new JwtTokenBuilder()
.AddSecurityKey(JwtSecurityKey.Create("SecurityKey"))
.AddSubject("Subject")
.AddIssuer("Issuer")
.AddAudience("Audience")
.AddClaim("Username", user.UserName)
.AddExpiry(expireTime)
.Build();
return token;
}
在.net core 2应用程序中,我使用 OWIN 启动类对所有具有 Authorize 授权的控制器验证我的令牌 strong>属性.
in .net core 2 application i use OWIN Startup class to validate my token for all controllers which have Authorize attribute.
控制器示例:
namespace solution.Controllers
{
public class ExampleController : ApiController
{
[HttpPost]
[Route("api/Example")]
[Authorize(Policy = "Session")]
public void Run()
{
// do something;
}
}
}
我的owin启动类,用于验证JWT令牌:
my owin startup class for validating JWT token :
using System;
using System.IO;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.IdentityModel.Tokens;
using System.Threading.Tasks;
namespace solution
{
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer(options =>
{
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuer = true,
ValidateAudience = true,
ValidateLifetime = true,
ValidateIssuerSigningKey = true,
ValidIssuer = "Issuer",
ValidAudience = "Audience",
IssuerSigningKey = JwtSecurityKey.Create("SecurityKey")
};
options.Events = new JwtBearerEvents
{
OnAuthenticationFailed = context =>
{
return Task.CompletedTask;
},
OnTokenValidated = context =>
{
return Task.CompletedTask;
}
};
});
services.AddAuthorization(options =>
{
options.AddPolicy("Session", policy => policy.RequireClaim("SessionId"));
});
services.AddSignalR();
services.AddCors(options =>
{
options.AddPolicy("CorsPolicy",
builder => builder
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials());
});
services.AddMvc();
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
loggerFactory.AddConsole();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.Use(async (context, next) =>
{
await next();
if (context.Response.StatusCode == 404 &&
!Path.HasExtension(context.Request.Path.Value) &&
!context.Request.Path.Value.StartsWith("/api/", StringComparison.OrdinalIgnoreCase))
{
context.Request.Path = "/index.html";
await next();
}
});
app.UseDeveloperExceptionPage();
app.UseAuthentication();
app.UseMvcWithDefaultRoute();
app.UseDefaultFiles();
app.UseStaticFiles();
app.UseCors(policyName: "CorsPolicy");
app.UseSignalR(routes =>
{
});
}
}
}
我只想在 owin 类中使用 asp.net Web API 中的这种结构,这可能吗? 如有任何更改,请帮助我
i want to use this structure in asp.net web api only change owin class, it's possible? please help me for any change
推荐答案
结构更改,以将我的实现从 .net core 2 转移到 asp.net Web API 2
structure change for transfer my implementation from .net core 2 to asp.net web api 2
我使用System.IdentityModel.Tokens.Jwt
名称空间来生成和验证JWT令牌.
i use System.IdentityModel.Tokens.Jwt
namespace for generate and validate JWT token.
.net core 2与System.IdentityModel.Tokens.Jwt version="5.1.4"
兼容,但asp.net Web API 2与System.IdentityModel.Tokens.Jwt version="4.0.2"
.net core 2 compatible with System.IdentityModel.Tokens.Jwt version="5.1.4"
but asp.net web api 2 compatible with System.IdentityModel.Tokens.Jwt version="4.0.2"
对软件包版本的相同更改也更改了代码,由于更改了软件包版本,我的代码部分也使用了System.IdentityModel.Tokens
命名空间而不是Microsoft.IdentityModel.Tokens
.
The same change in the package version made changes to the code, also the part of code i use the System.IdentityModel.Tokens
namespace instead of Microsoft.IdentityModel.Tokens
because of changing package versions.
代码更改:
JwtTokenBuilder类:
在此类中更改SigningCredentials
参数设置
var token = new JwtSecurityToken(
issuer: this.issuer,
audience: this.audience,
claims: claims,
expires: this.expireTime,
signingCredentials: new System.IdentityModel.Tokens.SigningCredentials(
this.securityKey,
Microsoft.IdentityModel.Tokens.SecurityAlgorithms.HmacSha256Signature
, Microsoft.IdentityModel.Tokens.SecurityAlgorithms.HmacSha256Signature));
安全密钥类:
更改安全密钥生成方法
using System.IdentityModel.Tokens;
using System.Text;
namespace solution.Authentication
{
public static class JwtSecurityKey
{
public static SymmetricSecurityKey Create(string secret)
{
return new InMemorySymmetricSecurityKey(Encoding.UTF8.GetBytes(secret));
}
}
}
控制器属性:
namespace solution.Controllers
{
public class ExampleController : ApiController
{
[HttpPost]
[Route("api/Example")]
[System.Web.Http.Authorize]
public void Run()
{
// do something;
}
}
}
我的主要更改是在 Starting OWIN 类中,并将Microsoft.Owin.Security.Jwt
软件包的版本从"3.1.0"更改为"3.0.0",以验证传入请求的JWT令牌.
My main change was in Startup OWIN class and change Microsoft.Owin.Security.Jwt
package version from "3.1.0" to "3.0.0" for validate JWT token for incoming requests.
实现:
using Microsoft.Owin;
using Owin;
using System.Web.Http;
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.Jwt;
[assembly: OwinStartup(typeof(solution.Startup))]
namespace solution
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.MapSignalR();
HttpConfiguration config = new HttpConfiguration();
config.MapHttpAttributeRoutes();
ConfigureOAuth(app);
app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
app.UseWebApi(config);
}
public void ConfigureOAuth(IAppBuilder app)
{
var issuer = "issuer";
var audience = "audience";
var secret = JwtSecurityKey.Create("SecurityKey").GetSymmetricKey();
// Api controllers with an [Authorize] attribute will be validated with JWT
var option =
new JwtBearerAuthenticationOptions
{
AuthenticationMode = AuthenticationMode.Active,
AllowedAudiences = new[] { audience },
IssuerSecurityTokenProviders = new IIssuerSecurityTokenProvider[]
{
new SymmetricKeyIssuerSecurityTokenProvider(issuer, secret)
}
};
app.UseJwtBearerAuthentication(
option
);
}
}
}
