System.IdentityModel.Tokens 和 Microsoft.IdentityModel.Tokens 之间的冲突

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)
}

创建标头时出现以下错误（var header = new JwtHeader(signingCredentials);) :

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，因为我所有的类型都指的是系统.IdentityModel.令牌。 并在文档中JwtHeader 构造函数 https://msdn.microsoft.com/en-us/library/dn451132(v=vs.114).aspx need System.IdentityModel.Tokens.SigningCredentials

我不知道出了什么问题...

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。

Example:

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);
}
