以下页面是项目的代码：如果我使用token = jwt.encode(payload,'secret', algorithm='HS256').decode('utf-8')语句然后
"r"对象没有属性"解码">
错误正在发生。此外，当我在没有.decode('utf-8')的情况下删除和使用它并继续执行下一个代码时。它运行良好。但当我应用payload = jwt.decode(token, 'secret', algorithm=['HS256'])时
然后
需要为"；算法"；当调用decode((时的自变量"；
出现上述错误。请帮我纠正这个错误。这就是上面提到的错误，即调用decode((错误时说算法参数应该被纠正。

您缺少一个"s"，该参数被称为"算法"；在解码功能中：
payload = jwt.decode(token, 'secret', algorithms=['HS256'])
并且还传递了一个可能值的数组。
当您调用encode时，参数为"；算法"；并且仅取单个值。
原因是在编码(即签名(过程中，您必须明确使用一种算法，因为令牌只能使用一种方法进行签名。但在解码(验证(过程中，您会告诉函数您接受哪些算法。
我必须通过verify=False，options=｛'verify_signature'：False｝以便使其工作。
另一个解决方案是将PyJWT版本降级到1.7.1，因此您不需要通过；算法"；论点
像这样：
jwt.decode(encoded, verify=False)
