从网页登录到Cognito,我获得了访问令牌和id令牌。现在我想在登录时运行Lambda函数并访问用户的一些数据,但这里失败了..
我得到InvalidLambdaResponseException: Invalid lambda trigger source
。
关于导致这种情况的任何想法?
Java Lambda代码就是这样:
public class LambdaFunctionHandler implements RequestHandler<CognitoEvent, CognitoEvent> {
@Override
public CognitoEvent handleRequest(CognitoEvent event, Context context)
{
context.getLogger().log("Input: " + event);
return event;
}
}
使用Javascript:
function loginCognito()
{
AWSCognito.config.region = 'us-east-1';
var authenticationData = {
Username : '***',
Password : '***',
};
var authenticationDetails = new AWSCognito.CognitoIdentityServiceProvider.AuthenticationDetails(authenticationData);
var poolData = { UserPoolId : 'us-east-1*********',
ClientId : '*******************'
};
var userPool = new AWSCognito.CognitoIdentityServiceProvider.CognitoUserPool(poolData);
var userData = {
Username : '***',
Pool : userPool
};
var cognitoUser = new AWSCognito.CognitoIdentityServiceProvider.CognitoUser(userData);
cognitoUser.authenticateUser(authenticationDetails,
{
onSuccess: function (result) {
/* ... */
},
onFailure: function(err) {
alert(err);
}
});
}

如果不了解您尝试做的事情的具体细节,并根据您要回复的错误,我相信triggerSource没有其中一个值的值:
PreSignUp_SignUp,PostConfirmation_ConfirmSignUp,PostConfirmation_ConfirmForgotPassword,PreAuthentication_Authentication, PostAuthentication_Authentication,CustomMessage_SignUp,CustomMessage_AdminCreateUser,CustomMessage_ResendCode,CustomMessage_ForgotPassword,CustomMessage_UpdateUserAttribute,CustomMessage_VerifyUserAttribute,CustomMessage_Authentication,DefineAuthChallenge_Authentication,CreateAuthChallenge_Authentication,VerifyAuthChallengeResponse_Authentication
现在,这不起作用的原因是CognitoEvent是CognitoSync服务的模板(示例),而不是您使用的userPools。目前我们没有提供输入事件的JAVA示例。
要使其工作,您需要有一个可以序列化以下JSON的输入对象
{
"version": 1,
"triggerSource": "PostAuthentication_Authentication",
"region": "<region>",
"userPoolId": "<userPoolId>",
"userName": "<userName>",
"callerContext": {
"awsSdk": "<calling aws sdk with version>",
"clientId": "<apps client id>",
...
},
"request": {
"userAttributes": {
"phone_number_verified": true,
"email_verified": true,
... //all custom attributes
}
},
"response": {}
};
