System.IdentityModel.Tokens 和 Microsoft.IdentityModel.Tokens

本文关键字：IdentityModel Tokens Microsoft System | 更新日期: 2023-09-27 17:56:33

我在使用 System.IdentityModel.Tokens 时遇到冲突：

using System;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.IdentityModel.Tokens;
using System.IdentityModel.Tokens.Jwt;
using System.Text;
public voidGenereToken()
{
    const string sec = "401b09eab3c013d4ca54922bb802bec8fd5318192b0a75f201d8b3727429090fb337591abd3e44453b954555b7a0812e1081c39b740293f765eae731f5a65ed1";
    var now = DateTime.UtcNow;
    var securityKey = new InMemorySymmetricSecurityKey(Encoding.Default.GetBytes(sec));
    var signingCredentials = new SigningCredentials(securityKey,
            SecurityAlgorithms.RsaSha256Signature, SecurityAlgorithms.Sha256Digest);
    var header = new JwtHeader(signingCredentials);
    var payload = new JwtPayload
    {
        {"iss", "a5fgde64-e84d-485a-be51-56e293d09a69"},
        {"scope", "https://example.com/ws"},
        {"aud", "https://example.com/oauth2/v1"},
        {"iat", now},
    };
    var secToken = new JwtSecurityToken(header, payload);
    var handler = new JwtSecurityTokenHandler();
    var tokenString = handler.WriteToken(secToken);
    Console.writeLine(tokenString)
}

当我创建标头时，我收到以下错误（var 标头 = new JwtHeader（签名凭据）;） ：

参数类型"System.IdentityModel.Tokens.SigningCredentials"不是可分配给参数类型'Microsoft.IdentityModel.Tokens.SigningCredentials'

我不明白，因为我的所有类型都是指System.IdentityModel.Tokens。在文档中 JwtHeader 构造函数需要 System.IdentityModel.Tokens.SigningCredentials

我不知道怎么了...

System.IdentityModel.Tokens 和 Microsoft.IdentityModel.Tokens

System.IdentityModel.Tokens.Jwt 版本 5.0.0.0 依赖于 Microsoft.IdentityModel.Tokens。

您需要在 Microsoft.IdentityModel.Tokens 命名空间中使用 SigningCredentials。

例：

using System;
using System.IdentityModel.Tokens;
using System.IdentityModel.Tokens.Jwt;
using System.Text;
public void voidGenereToken() {
    const string sec = "401b09eab3c013d4ca54922bb802bec8fd5318192b0a75f201d8b3727429090fb337591abd3e44453b954555b7a0812e1081c39b740293f765eae731f5a65ed1";
    var now = DateTime.UtcNow;
    var securityKey = new Microsoft.IdentityModel.Tokens.SymmetricSecurityKey(Encoding.Default.GetBytes(sec));
    var signingCredentials = new Microsoft.IdentityModel.Tokens.SigningCredentials(
        securityKey,
        SecurityAlgorithms.HmacSha256Signature);
    var header = new JwtHeader(signingCredentials);
    var payload = new JwtPayload
    {
            {"iss", "a5fgde64-e84d-485a-be51-56e293d09a69"},
            {"scope", "https://example.com/ws"},
            {"aud", "https://example.com/oauth2/v1"},
            {"iat", now},
        };
    var secToken = new JwtSecurityToken(header, payload);
    var handler = new JwtSecurityTokenHandler();
    var tokenString = handler.WriteToken(secToken);
    Console.WriteLine(tokenString);
}

可能是您使用的是 Jwt 版本 5.0.0.0 或更高版本。我以前遇到过同样的问题。

新版本的 JWT 处理程序接受 Microsoft.IdentityModel.Tokens 命名空间。

var tokenDescriptor = new Microsoft.IdentityModel.Tokens.SecurityTokenDescriptor
            {
                Subject = claimsIdentity,
                Audience = allowedAudience,
                Issuer = issuerName,
                Expires = DateTime.MaxValue,
                SigningCredentials = new Microsoft.IdentityModel.Tokens.SigningCredentials(
                    new Microsoft.IdentityModel.Tokens.SymmetricSecurityKey(symmetricKey), //symmetric key
                    System.IdentityModel.Tokens.SecurityAlgorithms.HmacSha256Signature,
                    System.IdentityModel.Tokens.SecurityAlgorithms.Sha256Digest)
            };
            var tokenHandler = new JwtSecurityTokenHandler();
            var token = tokenHandler.CreateToken(tokenDescriptor);
