描述证书

以下示例说明如何使用 DescribeCertificate 函数。

package com.amazonaws.samples; import com.amazonaws.services.certificatemanager.AWSCertificateManagerClientBuilder; import com.amazonaws.services.certificatemanager.AWSCertificateManager; import com.amazonaws.services.certificatemanager.model.DescribeCertificateRequest; import com.amazonaws.services.certificatemanager.model.DescribeCertificateResult; import com.amazonaws.auth.profile.ProfileCredentialsProvider; import com.amazonaws.auth.AWSStaticCredentialsProvider; import com.amazonaws.auth.AWSCredentials; import com.amazonaws.regions.Regions; import com.amazonaws.services.certificatemanager.model.InvalidArnException; import com.amazonaws.services.certificatemanager.model.ResourceNotFoundException; import com.amazonaws.AmazonClientException; /** * This sample demonstrates how to use the DescribeCertificate function in the AWS Certificate * Manager service. * * Input parameter: * CertificateArn - The ARN of the certificate to be described. * * Output parameter: * Certificate information * */ public class AWSCertificateManagerExample { public static void main(String[] args) throws Exception{ // Retrieve your credentials from the C:\Users\name\.aws\credentials file in Windows // or the ~/.aws/credentials file in Linux. AWSCredentials credentials = null; try { credentials = new ProfileCredentialsProvider().getCredentials(); } catch (Exception ex) { throw new AmazonClientException("Cannot load the credentials from file.", ex); } // Create a client. AWSCertificateManager client = AWSCertificateManagerClientBuilder.standard() .withRegion(Regions.US_EAST_1) .withCredentials(new AWSStaticCredentialsProvider(credentials)) .build(); // Create a request object and set the ARN of the certificate to be described. DescribeCertificateRequest req = new DescribeCertificateRequest(); req.setCertificateArn("arn:aws:acm:region:account:certificate/12345678-1234-1234-1234-123456789012"); DescribeCertificateResult result = null; try{ result = client.describeCertificate(req); } catch (InvalidArnException ex) { throw ex; } catch (ResourceNotFoundException ex) { throw ex; } // Display the certificate information. System.out.println(result); } }

如果成功,上述示例将显示类似于以下内容的信息。

{ Certificate: { CertificateArn: arn:aws:acm:region:account:certificate/12345678-1234-1234-1234-123456789012, DomainName: www.example.com, SubjectAlternativeNames: [www.example.com], DomainValidationOptions: [{ DomainName: www.example.com, }], Serial: 10: 0a, Subject: C=US, ST=WA, L=Seattle, O=ExampleCompany, OU=sales, CN=www.example.com, Issuer: ExampleCompany, ImportedAt: FriOct0608: 17: 39PDT2017, Status: ISSUED, NotBefore: ThuOct0510: 14: 32PDT2017, NotAfter: SunOct0310: 14: 32PDT2027, KeyAlgorithm: RSA-2048, SignatureAlgorithm: SHA256WITHRSA, InUseBy: [], Type: IMPORTED, } }
