建立 Amazon Cognito 身分集區

下列程式碼範例示範如何建立 Amazon Cognito 身份集區。

CLI
AWS CLI

若要使用 Cognito 身分集區提供者建立身分集區

此範例會建立名為的身分集區 MyIdentityPool。它具有 Cognito 身分集區提供者。不允許使用未驗證的身分。

命令：

aws cognito-identity create-identity-pool --identity-pool-name MyIdentityPool --no-allow-unauthenticated-identities --cognito-identity-providers ProviderName="cognito-idp.us-west-2.amazonaws.com/us-west-2_aaaaaaaaa",ClientId="3n4b5urk1ft4fl3mg5e62d9ado",ServerSideTokenCheck=false

輸出：

{
  "IdentityPoolId": "us-west-2:11111111-1111-1111-1111-111111111111",
  "IdentityPoolName": "MyIdentityPool",
  "AllowUnauthenticatedIdentities": false,
  "CognitoIdentityProviders": [
      {
          "ProviderName": "cognito-idp.us-west-2.amazonaws.com/us-west-2_111111111",
          "ClientId": "3n4b5urk1ft4fl3mg5e62d9ado",
          "ServerSideTokenCheck": false
      }
  ]
}
