Question

我正在使用python将openssl证书导入AWS ACM。我总是遇到错误：

Response:
{
      "errorMessage": "An error occurred (ValidationException) when calling the ImportCertificate operation: The certificate field contains more than one certificate. You can specify only one certificate in this field.",
      "errorType": "ClientError",
      "stackTrace": [
        "  File \"/var/task/lambda_function.py\", line 7, in lambda_handler\n    response = client.import_certificate(\n",
        "  File \"/var/runtime/botocore/client.py\", line 316, in _api_call\n    return self._make_api_call(operation_name, kwargs)\n",
        "  File \"/var/runtime/botocore/client.py\", line 626, in _make_api_call\n    raise error_class(parsed_response, operation_name)\n"
      ]
}

这是我的代码：

import boto3

client = boto3.client('acm')

def lambda_handler(event, context):
    response = client.import_certificate(
        Certificate='sample.vpn.crt',
        PrivateKey='sample.vpn.key',
        CertificateChain='ca.crt'
    )

任何帮助将不胜感激。

Answer 1

如boto3 docs中所述，三个参数的类型不应为字符串，而应为字节。对我来说，窍门是从软件包中读取证书文件，如下所示：

import boto3

client = boto3.client('acm')

def lambda_handler(event, context):
    certificate=open('sample.vpn.crt', 'rb').read()
    privatekey=open('sample.vpn.key', 'rb').read()
    chain=open('ca.crt', 'rb').read()

    response = client.import_certificate(
        Certificate=certificate,
        PrivateKey=privatekey,
        CertificateChain=chain
    )

不幸的是，在这种情况下，错误消息有些误导。如果仍然收到相同的错误消息，请确保您的证书文件具有ACM要求的格式。您可以通过尝试使用ACM控制台导入证书来进行测试。如果您收到相同的错误，请按照AWS在此troubleshooting page上提供的步骤进行操作。

Answer 2

发生错误是因为您应该传递证书的值，而不是文件名：

    CertificateArn='string',
    Certificate=b'bytes',
    PrivateKey=b'bytes',

因此，您可以尝试以下操作：

with open('sample.vpn.pem','r') as f:
    crt = f.read()

with open('sample.vpn.pem','rb') as f:
    key = f.read()

with open('ca.crt','rb') as f:
    chain = f.read()

response = client.import_certificate(
    Certificate=crt,
    PrivateKey=key,
    CertificateChain=chain)

使用python在AWS ACM中导入证书
