【问题描述】:
我有 javascript 客户端来执行 aws cognito 身份验证登录与提供商(Facebook、谷歌、Twitter 等)。我可以看到已成功从以下位置获取凭据:
var cognitoParam = {
'IdentityPoolId': 'ap-northeast-1:c8250ce6-xxxx-xxxx-xxxx-xxxxxxxxxxxx',
'RoleArn': 'arn:aws:iam::xxxxxxxxxxxx:role/roleName'
'Logins': {
'accounts.google.com': response.detail.id_token
}
};
var cognitoCred = new AWS.CognitoIdentityCredentials(cognitoParam);
它返回所有凭据对象。我还在 AWS 控制台上进行了检查,池 ID 已在联合身份池中列出/记录为提供者的经过身份验证的登录。
获得凭证后,我想使用 Cognito Sync Manager 将多个用户信息存储到云端:
var syncManager = new AWS.CognitoSyncManager();
syncManager.openOrCreateDataset('profileSet', function(err, dataset) {
// dataset.get
// dataset.put
// dataset.remove
});
所有方法(get、put、remove)都运行良好,但我在运行方法同步时遇到了问题。例如,放入新数据集后:
dataset.put("keyTes", "english", function(err,record){
if(!err){
dataset.synchronize({
onSuccess: function(dataset, newRecords) {
console.log(newRecords);
},
onFailure: function(err) {
console.log("Error while synchronizing data to the cloud: " + err);
}
});
}
});
显示错误:
将数据同步到云端时出错:AccessDeniedException: 用户: arn:aws:sts::xxxxxxxxxxxx:assumed-role/roleName/web-identity 无权执行:cognito-sync:ListRecords on resource: arn:aws:cognito-sync:ap-northeast-1:xxxxxxxxxxxx:identitypool/ap-northeast-1:c8250ce6-xxxx-xxxx-xxxx-xxxxxxxxxxxx/identity/ap-northeast-1:653aeca2-xxxx-xxxx-xxxx- xxxxxxxxxxxx/dataset/profileSet
在我的 IAM 角色中,我设置为:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {
"Federated": "cognito-identity.amazonaws.com"
},
"Action": "sts:AssumeRoleWithWebIdentity",
"Condition": {
"StringEquals": {
"cognito-identity.amazonaws.com:aud": "default"
},
"ForAnyValue:StringLike": {
"cognito-identity.amazonaws.com:amr": "authenticated"
}
}
}
]
}
和政策:
{ “版本”:“2012-10-17”, “陈述”: [ { “行动”:“认知同步:”, “效果”:“允许”, “资源”:“” } ] }

有人可以帮帮我吗?
