搭ListIdentityPools
配 AWS 開發套件或 CLI 使用
下列程式碼範例會示範如何使用ListIdentityPools
。

若要列出身分集區
此範例會列出身分集區。最多列出 20 個身分識別。
命令:
aws cognito-identity list-identity-pools --max-results 20
輸出:
{ "IdentityPools": [ { "IdentityPoolId": "us-west-2:11111111-1111-1111-1111-111111111111", "IdentityPoolName": "MyIdentityPool" }, { "IdentityPoolId": "us-west-2:11111111-1111-1111-1111-111111111111", "IdentityPoolName": "AnotherIdentityPool" }, { "IdentityPoolId": "us-west-2:11111111-1111-1111-1111-111111111111", "IdentityPoolName": "IdentityPoolRegionA" } ] }
