C# webapi中带有OWIN的复杂JSON Web令牌数组

我正在努力学习JWT和ouath。我遇到了JWT的形式，它将帮助我开发授权服务器

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，既然在添加声明时我们只能添加简单的字符串，那么这样的事情是如何实现的呢

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

任何指导方针都将不胜感激！谢谢

用于测试的代码 我想在JWT中使用的类

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

---

所以这个问题的关键是理解：）首先，应该注意以下几点

这基本上让我明白，我所需要的只是对自定义数组对象进行适当的序列化/反序列化

因此，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"
                        }
                    }
                };

现在剩下的挑战是对我的资源进行适当的授权。因此，我添加了定制的AuthorizationFilterAttribute

在其中，我使用来自的代码反序列化了声明

对于那些想要寻找更多代码的人，这是来自我的自定义过滤器的代码片段：

    // 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);
        }
    }

//检查是否有作用域
var AllScopes=principal.Claims.Where（p=>p.Type==“scopes”）；
//检查我们是否有所需的范围
foreach（所有作用域中的var singlescope）
{
Dictionary userscopes=JsonConvert.DeserializeObject（singlescope.Value）；
if（userscopes.Single（kvp=>kvp.Key==ScopeName）.Value.Contains（ScopeAccess））
{
//用户被授权，完成执行
返回Task.FromResult（空）；
}
}

我希望这能帮助别人

下面介绍如何使用.Net创建包含复杂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);

---

以下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);

这些天来，这从来都不是一个问题。可以使用 令牌的有效负载部分

如果你能提供一些示例代码来展示你已经尝试过的内容，这将为回答这个问题提供一个很好的起点。我已经添加了我目前正在尝试的代码。你不应该接受@stephane answer，因为它似乎完全符合你的要求。至少它对我有用..你能发布样本输出吗？@erPe更新。如果你还需要什么，请告诉我。你也可以看看这个

        {
