Question

我已经完成了文档中的所有步骤，通过email / pwd combo（工作）注册用户池，在身份提供者的身份池和用户池部分配置了FB身份提供程序，并实现了以下代码示例在http://docs.aws.amazon.com/cognito/latest/developerguide/facebook.html找到，并在下面使用我的身份池进行修改。

{代码}

function facebookLogin(){
    FB.login(function (response) {

        // Check if the user logged in successfully.
        if (response.authResponse) {

        console.log('You are now logged in.' + response.authResponse.accessToken);

        // Add the Facebook access token to the Cognito credentials login map.
        AWS.config.credentials = new AWS.CognitoIdentityCredentials({
            IdentityPoolId: 'us-east-1:eb997110-50b3-4e40-97ff-fbaf796da9ef',
            Logins: {
                'graph.facebook.com': response.authResponse.accessToken // cognitouser.idToken
            }
        });
        console.log('Added FB access token to Cognito.');

        // Obtain AWS credentials
        AWS.config.credentials.get(function(){
            //getCurrentUser();
            console.log('Got the aws creds.');
        });

        } else {
        console.log('There was a problem logging you in.');
        }
    });
}

{代码}

我可以单步执行并查看传递给CognitoIdentityCredentials的FB令牌，但没有错误，但用户永远不会在我的身份池或用户池中注册。

我错过了什么吗？

以下是我用于在AWS中创建联合身份的代码示例

    function loadCredentials(identityPool, provider, accessToken) {

        var params = {
            /*AccountId: window.appInfo.accountId,*/
            //RoleArn: window.ap
            IdentityPoolId: identityPool,
            Logins: {}
        };
        params.Logins[provider] = accessToken;
        AWS.config.credentials = new AWS.CognitoIdentityCredentials(params);
        AWS.config.credentials.get(function (err) {
            if (err) {
                console.log(err.message);
                console.log(err.stack);
            }
            else 
            {
                console.log("Cognito Identity Id: " + AWS.config.credentials.identityId);
                console.log("Worked");
            }

        });
    }
