Python PyJWT：自定义标头-从jwt标头中删除类型

如何从JWT头中删除字典值“typ”：“JWT”？我试过以下方法

jwt.encode(
    {
        "iat": 1588108543,
        "exp": 1588112143,
        "ehts": "...",
        "edts": "...."
    },
    privateKey,
    algorithm='RS256',
    headers={"alg": "RS256"})

但仍然在jwt头中获取

typ

。我正在使用pyjwt python库

输出：

谢谢扩展PyJWS.encode可以覆盖默认的头文件

扩展PyJWS.encode可能会覆盖默认标头

嗨，约翰，你能把结果加到你的问题上吗？嗨，开尔文。我只是将输出添加到问题中。感谢

headers={…}

参数用于其他头字段<代码>类型和

alg

始终存在。没有删除它们的选项。请参阅@jps，但我必须使我的api与某些服务兼容。有什么方法可以覆盖它吗？我想不出简单的方法。为什么这个标题会导致兼容性问题？嗨，John，你能把输出添加到你的问题中吗？嗨，开尔文。我只是将输出添加到问题中。感谢
