C# System.IdentityModel.Tokens.JwtSecurityToken自定义属性

My AuthServer当前正在使用以下代码生成JwtSecurityToken：

var token = new JwtSecurityToken(_issuer, audienceId, data.Identity.Claims, issued.Value.UtcDateTime, expires.Value.UtcDateTime, signingKey);
var handler = new JwtSecurityTokenHandler();
var jwt = handler.WriteToken(token);

有效载荷如下所示：

{
  "unique_name": "myUserName",
  "sub": "myUserName",
  "role": "API_User",
  "iss": "Automation",
  "aud": "099153c2625149bc8ecb3e85e03f0022",
  "exp": 1486056731,
  "nbf": 1483464731
}

{
  "unique_name": "myUserName",
  "sub": "myUserName",
  "role": "API_User",
  "iss": "Automation",
  "aud": "099153c2625149bc8ecb3e85e03f0022",
  "exp": 1486056731,
  "nbf": 1483464731,
  "profilePicture": "http://url/user.jpg"
}

我想在令牌负载中添加一些自定义字段/属性，例如ProfilePicURL，以便负载看起来像这样：

{
  "unique_name": "myUserName",
  "sub": "myUserName",
  "role": "API_User",
  "iss": "Automation",
  "aud": "099153c2625149bc8ecb3e85e03f0022",
  "exp": 1486056731,
  "nbf": 1483464731
}

{
  "unique_name": "myUserName",
  "sub": "myUserName",
  "role": "API_User",
  "iss": "Automation",
  "aud": "099153c2625149bc8ecb3e85e03f0022",
  "exp": 1486056731,
  "nbf": 1483464731,
  "profilePicture": "http://url/user.jpg"
}

如何添加这些自定义属性并确保令牌包含它们？

JwtSecurityToken

公开属性。派生自

字典

，因此只需将其添加到有效负载中即可

var token = new JwtSecurityToken(_issuer, audienceId, data.Identity.Claims, issued.Value.UtcDateTime, expires.Value.UtcDateTime, signingKey);
token.Payload["profilePicture"] = "http://url/user.jpg"
var handler = new JwtSecurityTokenHandler();
var jwt = handler.WriteToken(token);

---

使用

WriteToken

对令牌进行编码和签名是很重要的，因为简单地获取

RawData

属性将不起作用（令牌将不包含自定义声明）。

将其添加到有效负载属性，该属性派生自

Dictionary

ie

token.Payload[“profilePicture]”http://url/user.jpg"

谢谢！！在任何地方都找不到，不知道这是一本可以编辑的字典！
