以下页面为项目代码：如果使用token = jwt.encode(payload,'secret', algorithm='HS256').decode('utf-8')语句，则
“str”对象没有属性“decode”
发生错误。此外，当我删除和使用它没有.decode('utf-8')，并继续与进一步的代码。它是工作正常。但当我应用payload = jwt.decode(token, 'secret', algorithm=['HS256'])
那么
在调用decode（）时，需要传入“algorithms”参数的值。
出现了上述错误。请帮助我纠正此错误。这是前面提到的调用decode（）时说算法参数的错误。
