AWS Cognito错误：“ identityPoolId”未能满足约束 [英] AWS Cognito Error: 'identityPoolId' failed to satisfy constraint

问题描述

我是新认识的人。我正在尝试使用Lambda实施AWS Cognito。这是我关注的

这是JUnit测试

 公共类AuthenticateUser实现RequestHandler< Object，Object>。 {
 
 @Override 
公共对象handleRequest（对象输入，上下文上下文）{
 
 AuthenticateUserResponse authenticateUserResponse = new AuthenticateUserResponse（）; 
 @SuppressWarnings（ unchecked）
 LinkedHashMap inputHashMap =（LinkedHashMap）input; 
用户用户= authenticateUser（inputHashMap）; 
返回null； 
} 
 
 public User authenticateUser（LinkedHashMap input）{
 User user = null; 
字符串userName =（String）input.get（ userName）; 
字符串passwordHash =（String）input.get（ passwordHash）; 
 
试试{
 AmazonDynamoDBClient客户端=新的AmazonDynamoDBClient（）; 
 client.setRegion（Region.getRegion（Regions.US_EAST_1））; 
 DynamoDBMapper映射器=新的DynamoDBMapper（客户端）; 
用户= mapper.load（User.class，userName）; 
 
 if（user！= null）{
 System.out.println（ user found）; 
 if（user.getPasswordHash（）。equals（passwordHash））{
 System.out.println（匹配用户密码）; 
字符串openIdToken = getOpenIdToken（user.getUserId（））; 
 user.setOpenIdToken（openIdToken）; 
个返回用户； 
} else {
 System.out.println（密码不匹配）; 
} 
} else {
 System.out.println（找不到用户）; 
} 
} catch（Exception e）{
 System.out.println（ Error： + e.toString（））; 
} 
 
个返回用户； 
} 
  

这是输出

 用户发现
个用户密码与
匹配
  

但是我遇到了以下错误，因此 return user 语句失败

 检测到1个验证错误：'identityPoolId'
中的值'us-east-1_XXXXXX'无法满足约束：成员必须满足正则表达式模式：[\w-] +：[0-9a-f -] + 
（服务：AmazonCognitoIdentity；状态代码：400；错误代码：ValidationException； 
  

解决方案

您正在使用Cognito用户池ID作为身份池ID，这是两件事。身份池ID的格式为us-east-1：XXXX-XXXXXX-XXXX-XXXX

要获取身份池ID，您应该使用Cognito控制台的管理联合身份部分而不是管理用户池部分。希望这对您有所帮助。 / p>

I am new Cognito. I am trying to implement AWS Cognito using Lambda. This is the tutorial I am following.

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

This is the pool Id that I am using in the setIdentityPoolId

This is the JUnit test

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; 
}

This is the output

user found
user password matched

But I am getting the following error and hence, the return user statement is failing

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; 

解决方案

You are using a Cognito user pool id as the identity pool id. They are two different things. Identity pool ids are of format us-east-1:XXXX-XXXXXX-XXXX-XXXX.

To get an identity pool id you should use the "Manage Federated Identities" parts of the Cognito console not the "Manage User Pools" section. Hope this helps.
