我正在嘗試在 Actions on Google 中實現帳戶鏈接（使用此）我被困在其中的處理自動鏈接步驟。assertion當我嘗試使用此處指定的python-jose庫對其進行解碼時，我收到了請求！from jose import jwtkey = "728f4016652079b9ed99861bb09bafc5a45baa86" # PUBLIC KEY OF GOOGLE from https://www.googleapis.com/oauth2/v3/certsencoded = "ENCODED_ASSERTION"decoded = jwt.decode(encoded, key, algorithms='RS256')print (decoded)當我運行此代碼時，它顯示Traceback (most recent call last):File "/Users/jay.patel/env372/lib/python3.7/site-packages/jose/backends/pycrypto_backend.py", line 72, in __init__    self.prepared_key = RSA.importKey(key)  File "/Users/jay.patel/env372/lib/python3.7/site-packages/Crypto/PublicKey/RSA.py", line 757, in import_key    raise ValueError("RSA key format is not supported")ValueError: RSA key format is not supportedDuring handling of the above exception, another exception occurred:Traceback (most recent call last):  File "/Users/jay.patel/PycharmProjects/Prac/jwt.py", line 19, in <module>    decoded = jwt.decode(encoded, key, algorithms='RS256')  File "/Users/jay.patel/env372/lib/python3.7/site-packages/jose/jwt.py", line 135, in decode    payload = jws.verify(token, key, algorithms, verify=verify_signature)  File "/Users/jay.patel/env372/lib/python3.7/site-packages/jose/jws.py", line 77, in verify    _verify_signature(signing_input, header, signature, key, algorithms)  File "/Users/jay.patel/env372/lib/python3.7/site-packages/jose/jws.py", line 264, in _verify_signature    if not _sig_matches_keys(keys, signing_input, signature, alg):我究竟做錯了什么？？我剛剛使用了 RS256，因為它是在 Google 的公鑰中指定的（以JWK或PEM格式提供）PS 當我嘗試使用算法解碼此處的斷言時，RS256它顯示無效簽名錯誤，如下圖所示。
