如何解码JWT令牌? [英] How to decode JWT Token?

问题描述

我不了解该库的工作方式.你能帮我吗?

I don't understand how this library works. Could you help me please ?

这是我的简单代码:

public void TestJwtSecurityTokenHandler()
    {
        var stream =
            "eyJhbGciOiJSUzI1NiJ9.eyJpc3MiOiJJU1MiLCJzY29wZSI6Imh0dHBzOi8vbGFyaW0uZG5zY2UuZG91YW5lL2NpZWxzZXJ2aWNlL3dzIiwiYXVkIjoiaHR0cHM6Ly9kb3VhbmUuZmluYW5jZXMuZ291di5mci9vYXV0aDIvdjEiLCJpYXQiOiJcL0RhdGUoMTQ2ODM2MjU5Mzc4NClcLyJ9";
        var handler = new JwtSecurityTokenHandler();

        var jsonToken = handler.ReadToken(stream);
    }

这是错误:

该字符串必须采用紧凑的JSON格式，其格式为:Base64UrlEncodedHeader.Base64UrlEndcodedPayload.OPTIONAL，Base64UrlEncodedSignature'.

The string needs to be in compact JSON format, which is of the form: Base64UrlEncodedHeader.Base64UrlEndcodedPayload.OPTIONAL,Base64UrlEncodedSignature'.

如果您在 jwt.io网站中复制流，则效果很好:)

If you copy the stream in jwt.io website, it works fine :)

推荐答案

我找到了解决方案，只是忘了强制转换结果:

I found the solution, I just forgot to Cast the result:

var stream ="[encoded jwt]";  
var handler = new JwtSecurityTokenHandler();
var jsonToken = handler.ReadToken(stream);
var tokenS = handler.ReadToken(stream) as JwtSecurityToken;

我可以使用以下方式获得索赔:

I can get Claims using:

var jti = tokenS.Claims.First(claim => claim.Type == "jti").Value;
