AWS Cognito錯誤：'identityPoolId'未能滿足約束條件

我是新的Cognito。我正在嘗試使用Lambda實現AWS Cognito。這是我正在關注的tutorial。AWS Cognito錯誤：'identityPoolId'未能滿足約束條件

AmazonCognitoIdentityClient client = 
       new AmazonCognitoIdentityClient(); 
    GetOpenIdTokenForDeveloperIdentityRequest tokenRequest = new GetOpenIdTokenForDeveloperIdentityRequest(); 
    tokenRequest.setIdentityPoolId("us-east-1_XXXXXXX");

這是我使用的setIdentityPoolId池ID

這是JUnit測試

public class AuthenticateUser implements RequestHandler<Object, Object> { 

@Override 
public Object handleRequest(Object input, Context context) { 

    AuthenticateUserResponse authenticateUserResponse = new AuthenticateUserResponse(); 
    @SuppressWarnings("unchecked") 
    LinkedHashMap inputHashMap = (LinkedHashMap)input; 
    User user = authenticateUser(inputHashMap); 
    return null; 
} 

public User authenticateUser(LinkedHashMap input){ 
    User user = null; 
    String userName = (String) input.get("userName"); 
    String passwordHash = (String) input.get("passwordHash"); 

    try { 
     AmazonDynamoDBClient client = new AmazonDynamoDBClient(); 
     client.setRegion(Region.getRegion(Regions.US_EAST_1)); 
     DynamoDBMapper mapper = new DynamoDBMapper(client); 
     user = mapper.load(User.class, userName); 

     if(user != null){ 
      System.out.println("user found"); 
      if(user.getPasswordHash().equals(passwordHash)){ 
       System.out.println("user password matched"); 
       String openIdToken = getOpenIdToken(user.getUserId()); 
       user.setOpenIdToken(openIdToken); 
       return user; 
      } else { 
       System.out.println("password unmatched"); 
      } 
     } else { 
      System.out.println("user not found"); 
     } 
    } catch (Exception e) { 
     System.out.println("Error: " + e.toString()); 
    } 

    return user; 
}

這是輸出

user found 
user password matched

但我收到以下錯誤，因此，該return user聲明失敗

1 validation error detected: Value 'us-east-1_XXXXXX' at 'identityPoolId' 
failed to satisfy constraint: Member must satisfy regular expression pattern: [\w-]+:[0-9a-f-]+ 
(Service: AmazonCognitoIdentity; Status Code: 400; Error Code: ValidationException;

您使用的是Cognito用戶池ID爲標識池ID。他們是兩個不同的東西。身份池ID的格式爲us-east-1：XXXX-XXXXXX-XXXX-XXXX。

要獲取身份池ID，您應該使用Cognito控制檯的「管理聯合身份」部分而不是「管理用戶池」部分。希望這可以幫助。

救了我又一個2小時!!! –

@ Chetan-我認爲你應該在這個答案上使用upvotes作爲反饋，使得教程更好，並且比身份池的「Manage Federated Identities」更好的名字 – suku

@Chetan你將如何從用戶池ID獲取身份池ID？或者獲取與cognito用戶關聯的當前角色？ –
