无法反序列化解码 JWT python 的关键数据 [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.我在解码时收到此错误.代码在文档中给出.
导入jwtencoding_jwt='''eyJ0eXAiOiJKV1QiLCJhbG......'''secret=b''''-----开始公钥--MIIFRjCCBC6gAwIBAgIQCIdSGhpikQCjOIY154XoqzANBgkqhkiG9w0BAQsFADBN......-----结束公钥-----'''打印(jwt.decode(encoded_jwt，秘密，算法=['RS256']))<块引用>
raise ValueError("Could not deserialize key data.") ValueError: could不反序列化关键数据.
您能否帮我解决它，因为当我在 JWT 网站上使用它时，它正在工作.>
这是完整的错误日志..

pyjwt 库中存在一些问题.并且您必须从证书中获取公钥.
我使用了 openssl x509 -pubkey -noout -in cert.pem >pubkey.pem
然后从公钥我可以使用 authlib 库轻松解码它.

print(jwt.decode(encoded_jwt, secret , algorithms=['RS256']))
raise ValueError("Could not deserialize key data.") ValueError: Could not deserialize key data.
Could You please help me in resolving it beacuse when I use this it in the JWT website it's working.
This is the full error log..

There are some issues in the pyjwt library. and you must get the public key from the certificate.
I used openssl x509 -pubkey -noout -in cert.pem > pubkey.pem
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)
