问题描述

我正在尝试实现 JWT 令牌，但一直遇到以下异常:IDX10640:不支持算法:'http://www.w3.org/2001/04/xmldsig-more#hmac-sha256' 尝试将令牌写入压缩 json 字符串时.

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);
