关于python:PyJWT,需要PEM格式的密钥

PyJWT, Expecting a PEM-formatted key

我已经从图层复制粘贴了以下代码:

https://github.com/layerhq/support/blob/master/identity-services-samples/python/controller.py

有人告诉我另外两个人在mac机上成功运行了它。 我正在使用Windows 7,并且收到TypeError:运行代码时需要PEM格式的键:

#Read RSA key
root = os.path.dirname("__file__")
with open(os.path.join(root, RSA_KEY_PATH), 'r') as rsa_priv_file:
   
    #Not sure about adding the utf-8 AT ALL
    priv_rsakey = RSA.importKey(rsa_priv_file.read())

#Create identity token
#Make sure you have PyJWT and PyCrypto libraries installed and imported
identityToken = jwt.encode(
    payload={
       "iss": PROVIDER_ID,                 # String - The Provider ID found in the Layer Dashboard
       "prn": user_id,                     # String - Provider's internal ID for the authenticating user
       "iat": datetime.datetime.now(),              # Integer - Time of Token Issuance in RFC 3339 seconds
       "exp": datetime.datetime.utcnow() + datetime.timedelta(seconds=30),   # Integer - Arbitrary Token Expiration in RFC 3339 seconds
       "nce": nonce                        # The nonce obtained via the Layer client SDK.
    },
    key=priv_rsakey,
    headers = {
       "typ":"JWS",               # String - Expresses a MIME Type of application/JWS
       "alg":"RS256",             # String - Expresses the type of algorithm used to sign the token, must be RS256
       "cty":"layer-eit;v=1",     # String - Express a Content Type of Layer External Identity Token, version 1
       "kid": KEY_ID               # String - Private Key associated with"layer.pem", found in the Layer Dashboard
    },
    algorithm="RS256"
)

print identityToken

我不知道我的PEM格式化密钥应该如何设置,但是如下所示(我在发布之前手动更改了密钥):

-----END RSA PRIVATE KEY-----

我找不到有效的解决方案。
谁有想法? 谢谢


更改:

1
priv_rsakey = RSA.importKey(rsa_priv_file.read())

至:

1
priv_rsakey = rsa_priv_file.read()
