无法在解码JWT python时反序列化关键数据 [英] Could not deserialize key data on decoding JWT python

问题描述

我正在使用 pyjwt 库来解码JWT令牌。解码时出现此错误。代码是在文档中给出的。

I am using pyjwt library for decoding the JWT token. I got this error when I am decoding. The code was given in the documantation.

import jwt

encoded_jwt='''eyJ0eXAiOiJKV1QiLCJhbG......'''
secret=b''''-----BEGIN PUBLIC KEY-----
MIIFRjCCBC6gAwIBAgIQCIdSGhpikQCjOIY154XoqzANBgkqhkiG9w0BAQsFADBN
......
-----END PUBLIC KEY-----'''

print(jwt.decode(encoded_jwt, secret , algorithms=['RS256']))

raise ValueError（无法反序列化关键数据。）ValueError：
无法反序列化关键数据。

raise ValueError("Could not deserialize key data.") ValueError: Could not deserialize key data.

请帮我解决它，因为当我在 JWT 网站正在运行。

Could You please help me in resolving it beacuse when I use this it in the JWT website it's working.

这是完整的错误日志。

推荐答案

pyjwt中存在一些问题图书馆。并且您必须从证书中获取公钥。

There are some issues in the pyjwt library. and you must get the public key from the certificate.

我使用了 openssl x509 -pubkey -noout -in cert.pem> pubkey.pem

然后从公钥中，我可以使用authlib库轻松对其进行解码。

then from the public key I could easily decode it using authlib library.

from authlib.specs.rfc7519 import jwt

encoded_jwt='''eyJ0eXAiOiJ....'''
secret=b'''-----BEGIN PUBLIC KEY-----
......
-----END PUBLIC KEY-----'''
claims = jwt.decode(encoded_jwt, secret)
print(claims)
