python - AWS 认知。如何在 Python 中解码 JWT

问题描述

我想在 Django 应用程序中使用 Cognito 身份提供程序 (Facebook) 对用户进行身份验证。当用户登录时，他会被重定向到主页，并使用access_token和id_token。这些是 JWT 令牌。我需要对它们进行解码以获取有关用户的信息。如何实现？

我尝试使用jwt库。许多资源说我需要将 PUBLIC_KEY 转换为 PEM 格式来解码这些令牌。我访问了： https://cognito-idp.{aws-region}.amazonaws.com/{user-pool-id}/.well-known/jwks.json 并得到了字典：

{
  "keys": [
    {
      "alg": "RS256",
      "e": "AQAB",
      "kid": "cKgEILaVv5nXrJNBtfdaEVfA9Sn+GNdMpXbO58Li+eLyiA=",
      "kty": "RSA",
      "n": "kpE2A8GfBoDiLcnHme9WLSIMezPAXg8ibZ8hIa4GvmJAT1LmR9CDN0Yt-JlKE_gH73HbldpgqCbflygbcZtdn1RMdfafdafaQq3sOY0RJqC8-jdZTWb0Cbw2E-fmmOtgHqz11ZlbqaZYpcRYvyNwuWQs05kikzaUudwp05TTd4N0VznbMMm9peu_Ghw7nqlgkvU8WWO6tD_LzF8VDTroKdGAnrh3kwRVY8le5JwzoGMDVbNtOQFwla8yyxNfRRFQVkcnOxb14BhrO3N8ZsI-E9eB9ZbUNt27DxAMjxsNzERSUx3gm7zq-d2SYyZ31P_FNxOTS0RlKPN69Jlscack7ghM_nZdnw",
      "use": "sig"
    },
    {
      "alg": "RS256",
      "e": "AQAB",
      "kid": "wMYp8SsLhXBtE2wbYK1hQfdafadfadeiYkDYXctg1GkdmTTFs+I=",
      "kty": "RSA",
      "n": "i_W1pexAB1FhY3oJ0jEGeks1b8jCFZOWU7PAvzi3kdeP7JR2IP91W8FV9ou6gT1dn6F8ZbDvJEF9PNJkmQxwvHkoeYzgaOhNFXBU5Jfv20rQfdafa56PufchgtGndaI22TnnPDg_L5UElaljJvmzTcDTk0xHqJRxhw2LAqembfij5TV_8mSHpqIbWvppOTqT7s3zI7DdfDLDOX7CHFRht3uesX5drVo-S9IsJCJ2l3rCChTCy8e32YY68iHH40t5vVPkuqr1ffMfKYkyXC3urliCawRKnrk62ngAskjRiAihmIl8E79_Ddfn5O5RYqLY71Q4T6Epep4C1ygjlBrToFd8Haw",
      "use": "sig"
    }
  ]
}

我不知道从这里拿什么。
