显示 IAM 托管策略的策略文档

此示例向您演示如何使用Amazon SDK for .NET以显示策略文档。应用程序创建 IAM 客户端对象,查找给定 IAM 托管策略的默认版本,然后以 JSON 显示策略文档。

以下各节提供了此示例的片段。这些区域有:例子的完整代码在此之后显示,并且可以按原样构建和运行。

查找默认版本

以下代码段查找给定 IAM 策略的默认版本。

这个示例在本主题末尾的显示了这个片段正在使用中。

// // Method to determine the default version of an IAM policy // Returns a string with the version private static async Task<string> GetDefaultVersion( IAmazonIdentityManagementService iamClient, string policyArn) { // Retrieve all the versions of this policy string defaultVersion = string.Empty; ListPolicyVersionsResponse reponseVersions = await iamClient.ListPolicyVersionsAsync(new ListPolicyVersionsRequest{ PolicyArn = policyArn}); // Find the default version foreach(PolicyVersion version in reponseVersions.Versions) { if(version.IsDefaultVersion) { defaultVersion = version.VersionId; break; } } return defaultVersion; }

显示策略文档

以下代码段以 JSON 形式显示给定 IAM 策略的策略文档。

这个示例在本主题末尾的显示了这个片段正在使用中。

// // Method to retrieve and display the policy document of an IAM policy private static async Task ShowPolicyDocument( IAmazonIdentityManagementService iamClient, string policyArn, string defaultVersion) { // Retrieve the policy document of the default version GetPolicyVersionResponse responsePolicy = await iamClient.GetPolicyVersionAsync(new GetPolicyVersionRequest{ PolicyArn = policyArn, VersionId = defaultVersion}); // Display the policy document (in JSON) Console.WriteLine($"Version {defaultVersion} of the policy (in JSON format):"); Console.WriteLine( $"{HttpUtility.UrlDecode(responsePolicy.PolicyVersion.Document)}"); }
