DNX核心5.0 JwtSecurityTokenHandler" IDX10640：不支持算法：“http://www.w3.org/2001/04/xmldsig-more#hmac-sha256'" [英] DNX Core 5.0 JwtSecurityTokenHandler "IDX10640: Algorithm is not supported: 'http://www.w3.org/2001/04/xmldsig-more#hmac-sha256'"

问题描述

我想实现JWT令牌，但保持运行到以下异常：IDX10640：不支持算法：的 http://www.w3.org/2001/04/xmldsig-more#hmac-sha256 试图写令牌紧凑JSON字符串时。

 常量字符串发行人=发行人; 
常量字符串观众=观众; 
字节[] = keyForHmacSha256新的字节[32]; 
新的随机（）的nextBytes（keyForHmacSha256）; 
 
变种索赔=新的List<权利要求GT; {新的索赔（DEVICEID，12）}; 
变种现在= DateTime.UtcNow; 
变种期满= now.AddHours（1）; 
变种signingCredentials =新SigningCredentials（
新SymmetricSecurityKey（keyForHmacSha256），
 SecurityAlgorithms.HmacSha256Signature，SecurityAlgorithms.Sha256Digest）; 
 
变种令牌=新JwtSecurityToken（发行人，观众，索赔，目前，过期，signingCredentials）; 
返回_tokenHandler.WriteToken（标记）; 
  

在解决这个任何想法？

更新1：

错误上面System.IdentityModel.Tokens.Jwt的发生：5.0.0-beta7-208241120

更新2：

更新代码

< DIV CLASS =h2_lin>解决方案

我们没有为对称密钥的支持现在。希望能得到在不久。

I'm trying to implement JWT tokens but keep running into the following exception: IDX10640: Algorithm is not supported: 'http://www.w3.org/2001/04/xmldsig-more#hmac-sha256' when trying to write the token to compact json string.

const string issuer = "issuer";
const string audience = "audience";
byte[] keyForHmacSha256 = new byte[32];
new Random().NextBytes(keyForHmacSha256);

var claims = new List<Claim> { new Claim("deviceId", "12") };
var now = DateTime.UtcNow;
var expires = now.AddHours(1);
var signingCredentials = new SigningCredentials(
    new SymmetricSecurityKey(keyForHmacSha256), 
    SecurityAlgorithms.HmacSha256Signature, SecurityAlgorithms.Sha256Digest);

var token = new JwtSecurityToken(issuer, audience, claims, now, expires, signingCredentials);
return _tokenHandler.WriteToken(token);

Any ideas on solving this?

Update 1:

The error above occurs with "System.IdentityModel.Tokens.Jwt": "5.0.0-beta7-208241120"

Update 2:

Updated code

解决方案

We don't have support for symmetric keys right now. Hope to get that in soon.
