可以在此处找到Cognito用户池的文档:
http://docs.aws.amazon.com/cognito/latest/developerguide/how-to-manage-user-accounts.html
在这里他们没有说你是否可以通过自动生成的子属性查询用户,这是一个uuid。它明确表示您无法通过自定义属性搜索用户,但sub / uuid不是自定义属性。奇怪的是,在可搜索属性列表中,sub / uuid不是其中之一。当然,虽然你可以通过他们的UUID查找用户,但是如何做到这一点?
答案 0 :(得分:2)
你知道,我使用过COgnito但从不需要通过sub(或用户名以外的其他参数)查找。我调查了它,因为肯定你可以,但它不是很清楚(就像他们的很多文档)。这是我看到你可以尝试的...希望它能帮助人类。
// the imported ListUsersResult is...
import com.amazonaws.services.cognitoidp.model.ListUsersRequest;
import com.amazonaws.services.cognitoidp.model.ListUsersResult;
// class var
protected final AWSCognitoIdentityProviderClient identityUserPoolProviderClient;
// omitted stuff...
// initialize the Cognito Provider client. This is used to talk to the user pool
identityUserPoolProviderClient = new AWSCognitoIdentityProviderClient(new BasicAWSCredentials(AWS_ACCESS_KEY, AWS_SECRET_KEY)); // creds are loaded via variables that are supplied to my program dynamically
identityUserPoolProviderClient.setRegion(RegionUtils.getRegion(USER_POOL_REGION)); // var loaded
// ...some code omitted
ListUsersRequest listUsersRequest = new ListUsersRequest();
listUsersRequest.withUserPoolId(USER_POOL_ID); // id of the userpool, look this up in Cognito console
listUsersRequest.withFilter("sub=xyz"); // i THINK this is how the Filter works... the documentation is terribad
// get the results
ListUsersResult result = identityUserPoolProviderClient.listUsers(listUsersRequest);
List<UserType> userTypeList = result.getUsers();
// loop through them
for (UserType userType : userTypeList) {
List<AttributeType> attributeList = userType.getAttributes();
for (AttributeType attribute : attributeList) {
String attName = attribute.getName();
String attValue = attribute.getValue();
System.out.println(attName + ": " + attValue);
}
}
如果你有用户名,你就可以得到像这样的用户
// build the request
AdminGetUserRequest idRequest = new AdminGetUserRequest();
idRequest.withUserPoolId(USER_POOL_ID);
idRequest.withUsername(username);
// call cognito for the result
AdminGetUserResult result = identityUserPoolProviderClient.adminGetUser(idRequest);
// loop through results
