Gunakan ListIdentityPools dengan AWS SDK atau CLI

Contoh kode berikut menunjukkan cara menggunakanListIdentityPools.

CLI

AWS CLI

Untuk membuat daftar kumpulan identitas

Contoh ini mencantumkan kumpulan identitas. Ada maksimal 20 identitas yang terdaftar.

Perintah:

aws cognito-identity list-identity-pools --max-results 20

Output:

{
  "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"
      }
  ]
}

Contoh 1: Mengambil daftar Identity Pools yang ada.

Get-CGIIdentityPoolList

Output:

IdentityPoolId                                                     IdentityPoolName
