.net – AspNetCore中的Okta OAuth2令牌验证失败

我想在我的API上的承载头中验证来自Okta的JWT访问令牌,但验证始终无法给出以下错误：

我想知道原因是否可以,令牌中的公钥’kid’与Okta上Keys端点中的公钥不同？

{"keys": [{"alg": "RS256","e": "AQAB","n": "wtkBXocJLBE-ArN56pLzSiR3x2w99R2d_rlCpFN__3k1I6P0vcfE4SKwoafzucaG-kEwy9pn4p49z0O24UHX0NmdxOMhyFmJsfss0tK0AkBhXB-e9kk5r316ePRtb7eo8uAnjNP7w2T6sSqwdppw7I8NQa4KrFIYFVDx4xDcYMfnGrKjKFdghxSpG2dP7vcQsjJHkMyEHYj7nTTyplReX21_Et2F5zHqvqQZ1JRuL_Ol-JrSEeM0Hznpb7kpggnFUA_xnzcR4AhT5P2WNNNenlfurjM_AN1ymV8DT04Tx7tp6G60N1AkDw4t4Q0LfuevQ","kid": "gtUiz-YdlCSRpr0Ue7LRuEtqgVqRmDWpe5ZuvBaWgVk","kty": "RSA","use": "sig"}]}

这是WebAPI上的设置：

app.UseJwtBearerAuthentication(new JwtBearerOptions
{
    AuthenticationScheme = JwtBearerDefaults.AuthenticationScheme,
    Audience = "http://api.azurewebsites.net",
    Authority = "https://dev-606497.oktapreview.com"
});

最佳答案 为了通过公钥url获取访问令牌的密钥,需要为Okta组织启用一些功能.请发送电子邮件至developers@okta.com
