验证Azure广告访问令牌时签名无效，但id令牌有效

问题描述：

使用jwt.io验证我的Azure广告访问令牌时，我得到了无效签名。但是，我的id令牌可以很好地验证！

I am getting invalid signature while using jwt.io to validate my azure ad access token. My id token, however, validates just fine!

我已经看到并尝试了

和

，但都不适用于我的访问令牌。

I have seen and tried the solutions suggested in
Invalid signature while validating Azure ad access token
and
https://nicksnettravels.builttoroam.com/post/2017/01/24/Verifying-Azure-Active-Directory-JWT-Tokens.aspx
but neither works for my access token.

访问权限和ID令牌是通过Adal.js生成的：

The access and Id token is generated via Adal.js:

    var endpoints = {
        "https://graph.windows.net": "https://graph.windows.net"
    };
    var configOptions = {
        tenant: "<ad>.onmicrosoft.com", // Optional by default, it sends common
        clientId: "<app ID from azure portal>",
        postLogoutRedirectUri: window.location.origin,
        endpoints: endpoints,
    }
    window.authContext = new AuthenticationContext(configOptions);

为什么我可以验证我的ID令牌，但不能验证我的访问令牌？

Why can I validate my ID token, but not my access token?

答

请参考线程： https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/issues/609

但是如果查看Jwt.Header，您将看到一个 nonce。这意味着您需要特殊处理。正常处理将失败。

but if look at the Jwt.Header you will see a 'nonce'. This means you need special processing. Normal processing will fail.

因此，如果随机数包含在访问令牌中，请使用JWT.io验证签名或JwtSecurityToken将不会成功。

So if nonce includes in access token , validate signature with JWT.io or JwtSecurityToken won't success .
