是否可以使用Java AWS API更新Route53记录？

Question

我在亚马逊Route53上有一个托管域。在这个域名下，我有一个子域的'A‘记录。

我希望能够使用Java API更新'A‘记录的IP地址。但是，当查看com.amazonaws.services.route53.model.Change类的setAction方法时，它只接受CREATE或DELETE值。这似乎与Java API在幕后发送的XML消息中允许的值相匹配。

有没有办法只更新IP地址，或者我必须删除原始记录，然后重新创建它？

谢谢

Answer 1

唯一的方法是使用here中提到的DELETE / CREATE sequence。

创建更改批处理请求

要创建变更批处理请求，请使用ChangeResourceRecordSets操作ChangeBatch元素。对于要更新的每个记录，可以在ChangeBatch元素中使用创建和删除操作。如果只创建记录，则只需使用CREATE actions。

使用下面这段代码，它对我很有效：

ResourceRecord record = new ResourceRecord(loadBalancer);
List<ResourceRecord> records = new ArrayList<ResourceRecord>();
records.add(record);
ResourceRecordSet recordsSet = new ResourceRecordSet();
recordsSet.setResourceRecords(records);
recordsSet.setType(RRType.CNAME);
recordsSet.setTTL(900L);
recordsSet.setName(subdomain + ".");
Change change = new Change(ChangeAction.CREATE, recordsSet);
List<Change> changes = new ArrayList<Change>();
changes.add(change);
ChangeBatch batch = new ChangeBatch(changes);
ChangeResourceRecordSetsRequest request = new ChangeResourceRecordSetsRequest();
request.setChangeBatch(batch);
request.setHostedZoneId(hostedZoneId);
ChangeResourceRecordSetsResult result = getRoute53Client().changeResourceRecordSets(request);
System.out.println(result);

只需用适当的数据替换我使用的变量即可。(子域、loadBalancer和hostedZoneId)。方法getRoute53Client()从AWS API返回AmazonRoute53Client类的一个实例。

        ResourceRecord rr = new ResourceRecord(IPAdress); // IPAddress will be String variable that has IP value
        List<ResourceRecord> rrList = new ArrayList<ResourceRecord>();
        rrList.add(rr);

        // Create a ResourceRecordSet
        ResourceRecordSet resourceRecordSet = new ResourceRecordSet();
        resourceRecordSet.setName(domainName); //domainName is String value of your domain
        resourceRecordSet.setType(RRType.A); //type of ResourceRecordSet
        resourceRecordSet.setTTL(new Long(300));
        resourceRecordSet.setWeight(new Long(0));
        resourceRecordSet.setResourceRecords(rrList);

        // Create a change
        Change change = new Change(ChangeAction.CREATE, resourceRecordSet);
        List<Change> changesList = new ArrayList<Change>();
        changesList.add(change);

        // Create a change batch
        ChangeBatch changeBatch = new ChangeBatch(changesList);

        // Create ChangeResourceRecordSetRequest.
        ChangeResourceRecordSetsRequest request = new ChangeResourceRecordSetsRequest(hostedZoneID, changeBatch); //hostedZoneId is variable that is the id of HostedZone

        // Send the request and get the response.
        ChangeResourceRecordSetsResult result = amazonRoute53Client.changeResourceRecordSets(request);

        // Print the result
        System.out.println(result.getChangeInfo());
