使用 OWIN 的 webapi 中的复杂 JSON Web 令牌数组

Question

我正在尝试学习 JWT 和 ouath。我遇到了 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']
    }
  }
}

然而，由于在添加声明时我们只能添加简单的字符串，如何实现这样的事情呢？

到目前为止我看到的唯一方法是使用 JSON.serialization - 来自

new Claim(someClass,JsonConvert.SerializeObject(result)

任何指南将不胜感激！谢谢！

用于测试的代码

Class 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时：

{
  "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

所以这个问题的关键是理解:) 首先要注意的是下面的escape characters。

这基本上让我明白我所需要的只是适当的 serialization/deserialization 自定义数组对象。

所以我创建了以下内容作为每个范围的基础

                Dictionary<string, List<string>> xx3 = new Dictionary<string, List<string>>()
                {
                    {
                        "s3",new List<string>()
                        {
                            "access1" , "access2"
                        }
                    }
                };

然后简单地序列化这个对象并添加为声明

            var cos3 = JsonConvert.SerializeObject(xx3, Formatting.Indented);

            identity.AddClaim(new Claim("scopes", cos1));

现在剩下的挑战是对我的 resources.So 的适当授权我添加了自定义的 AuthorizationFilterAttribute

在那里我使用来自 here

的代码反序列化声明

对于那些想要寻找更多代码的人来说，这是我的自定义过滤器的片段：

    // Check if we have scopes 
    var AllScopes = principal.Claims.Where(p => p.Type == "scopes");

    // Check if we have desired scope 
    foreach (var singlescope in AllScopes)
    {
        Dictionary<string, List<string>> userscopes = JsonConvert.DeserializeObject<Dictionary<string, List<string>>>(singlescope.Value);

        if (userscopes.Single(kvp => kvp.Key == ScopeName).Value.Contains(ScopeAccess))
        {
            //User is Authorized, complete execution
            return Task.FromResult<object>(null);
        }
    }

我希望这会对某人有所帮助！

Answer 2

以下是如何使用 .Net 创建具有复杂 JSON 声明的 JWT 令牌。

使用 Nuget 获取库：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);

这会产生一个令牌，例如

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

Answer 3

这是我创建复杂令牌的方式：

var securityKey = new InMemorySymmetricSecurityKey(Encoding.Default.GetBytes("401b09eab3c013d4ca54922bb802bec8fd5318192b0a75f201d8b3727429090fb337591abd3e44453b954555b7a0812e1081c39b740293f765eae731f5a65ed1"));
var signingCredentials = new SigningCredentials(securityKey,
                SecurityAlgorithms.HmacSha256Signature,
                SecurityAlgorithms.Sha256Digest);

var header = new JwtHeader(signingCredentials);
var payload = new JwtPayload();

payload.AddClaims(claims);
payload.Add("tags", _tags.ToArray()); // this guy accepts object!

var token = new JwtSecurityToken(header, payload);
var tokenString = securityTokenHandler.WriteToken(token);

Answer 4

This has been never an issue these days. It can be solved using the Payload section of the token.

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

Sample code

        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;
    }

Output
