创建一个 Amazon Cognito 身份池

使用 Cognito 身份池提供者创建身份池

此示例创建了一个名为的身份池 MyIdentityPool。它有一个 Cognito 身份池提供者。不允许使用未经身份验证的身份。

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

输出：

{
  "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
      }
  ]
