带有OWIN的webapi中的复杂JSON Web令牌数组

Question

我正在努力学习JWT和ouath.我遇到过JWT的形式,它可以帮助我开发我的授权服务器.

我遇到的格式如下:

{
  iat: 1416929061, 
  jti: "802057ff9b5b4eb7fbb8856b6eb2cc5b",
  scopes: {
    users: {
      actions: ['read', 'create']
    },
    users_app_metadata: {
      actions: ['read', 'create']
    }
  }
}

但是,因为在添加声明时我们只能添加简单的字符串,这样可以实现这样的事情吗？

我到目前为止看到的唯一方法是使用JSON.serialization - 来自/sf/answers/1909558031/

new Claim(someClass,JsonConvert.SerializeObject(result)

任何准则将不胜感激!谢谢!

用于测试的代码

我想在JWT中使用

public class MyTes
{
    public string       area { get; set; }
    public List<string> areapermissions { get; set; }
}

然后我使用以下代码生成令牌

        var identity = new ClaimsIdentity("JWT");

        var cos = new List<string>();

        cos.Add("aaa");
        cos.Add("bbb");

        MyTes vario = new MyTes()
        {
            area = "someregion",
            areapermissions = cos
        };




        identity.AddClaim(new Claim(ClaimTypes.Name, context.UserName));
        identity.AddClaim(new Claim("sub", context.UserName));
        identity.AddClaim(new Claim(ClaimTypes.Role, "Manager"));
        identity.AddClaim(new Claim(ClaimTypes.Role, "Supervisor"));
        identity.AddClaim(new Claim("scope", "xyz1"));
        identity.AddClaim(new Claim("scope", "xyz2"));
        identity.AddClaim(new Claim("scope", "xyz3"));
        identity.AddClaim(new Claim("APIs", JsonConvert.SerializeObject(cos)));
        identity.AddClaim(new Claim("APIs2", JsonConvert.SerializeObject(vario)));

这没有错误,当我解码我现在得到的票:

{
  "unique_name": "Rafski",
  "sub": "Rafski",
  "role": [
    "Manager",
    "Supervisor"
  ],
  "scope": [
    "xyz1",
    "xyz2",
    "xyz3"
  ],
  "APIs": "[\"aaa\",\"bbb\"]",
  "APIs2": "{\"area\":\"someregion\",\"areapermissions\":[\"aaa\",\"bbb\"]}",
  "iss": "http://kurwa.mac",
  "aud": "7aaa70ed8f0b4807a01596e2abfbd44d",
  "exp": 1429351056,
  "nbf": 1429349256
}

Answer 1

以下是如何使用.Net创建具有复杂JSON声明的JWT令牌.

使用Nuget获取Library:System.IdentityModel.Tokens.Jwt

然后使用以下代码创建JWT令牌.

var keybytes = Convert.FromBase64String(YOUR_CLIENT_SECRET);
        var signingCredentials = new SigningCredentials(
                    new InMemorySymmetricSecurityKey(keybytes),
                    SecurityAlgorithms.HmacSha256Signature,
                    SecurityAlgorithms.Sha256Digest);

        var nbf = DateTime.UtcNow.AddSeconds(-1);
        var exp = DateTime.UtcNow.AddSeconds(120);
        var payload = new JwtPayload(null, "", new List<Claim>(), nbf, exp);

        var users = new Dictionary<string, object>();
        users.Add("actions", new List<string>() { "read", "create" });
        var scopes = new Dictionary<string, object>();
        scopes.Add("users", users);
        payload.Add("scopes", scopes);

        var jwtToken = new JwtSecurityToken(new JwtHeader(signingCredentials), payload);
        var jwtTokenHandler = new JwtSecurityTokenHandler();
        return jwtTokenHandler.WriteToken(jwtToken);

哪个会产生诸如此类的令牌

{
  "typ": "JWT",
  "alg": "HS256"
}    
{
      "exp": 1433254394,
      "nbf": 1433254273,
      "scopes": {
        "users": {
          "actions": [
            "read", "create"
          ]
        }
      }
    }

这些天这从来都不是问题。可以使用令牌的有效负载部分来解决。

**using System.IdentityModel.Tokens.Jwt;** //Vesrion 5.5.0

示例代码

        public static string Generate()
    {

        IList<User> users = new List<User> {
            new User { Id = 1, Name = "User One" },
            new User { Id = 2, Name = "User Two" },
            new User { Id = 3, Name = "User Three" }
        };

        IList<Company> companies = new List<Company>
        {
            new Company{ Id = 1, Code = "C01", Name = "Company I", Users = users },
            new Company{ Id = 2, Code = "C03", Name = "Company II", Users = null },
            new Company{ Id = 3, Code = "C03", Name = "Company III", Users = users }
        };

        IList<Branch> branches = new List<Branch>
        {
            new Branch{Id = 1, CompanyId = 1, Code="B01", Name = "Branch 1.1"},
            new Branch{Id = 2, CompanyId = 1, Code="B02", Name = "Branch 1.2"},
            new Branch{Id = 3, CompanyId = 1, Code="B03", Name = "Branch 1.3"},
            new Branch{Id = 4, CompanyId = 2, Code="B04", Name = "Branch 2.1"},
            new Branch{Id = 5, CompanyId = 2, Code="B05", Name = "Branch 2.2"},
        };

        var payload = new JwtPayload       {
            { "companies", companies },
            { "branches", branches }
        };

        string key = "eyJjb21wYW5pZXMiOlt7IklkIjoxLCJDb2RlIjoiQzAxIiwiTmFtZSI6IkNvbXBhbnkgSSIsIkJyYW5jaGVzIjpudWxsLCJVc2VycyI6W3siSWQiOjEsIk5hbWUiOiJV";
        var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(key));
        var credentials = new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256Signature);
        var header = new JwtHeader(credentials);

        var secToken = new JwtSecurityToken(header, payload);

        var handler = new JwtSecurityTokenHandler();
        var tokenString = handler.WriteToken(secToken);

        Console.WriteLine(secToken);
        Console.WriteLine(tokenString);

        return tokenString;
    }
