JAVA实现对阿里云DNS的解析管理

1、阿里云DNS的SDK依赖

<dependency>
<groupId>com.aliyun</groupId>
<artifactId>tea-openapi</artifactId>
<version>0.0.19</version>
</dependency>
<dependency>
<groupId>com.aliyun</groupId>
<artifactId>alidns20150109</artifactId>
<version>2.0.1</version>
</dependency>

2、第一个方法：创建SDK客户端实例

所有解析记录的操作都要通过这个客户端实例来进行，所以要首先创建这个实例，需要阿里云的AccessKey（AppId和AppSecret）

/**
* <p>
* 创建客户端实例
* </p>
*
* @return
* @throws Exception
*/
private Client createClient() throws Exception{
AliConfig api = APIKit.getAliConfig(); //返回阿里云的AccessKey参数
if(api == null) throw new ErrException("未配置阿里云API参数！");
Config config = new Config();
config.accessKeyId = api.getAppId();
config.accessKeySecret = api.getAppSecret();
config.endpoint = "alidns.cn-beijing.aliyuncs.com";
return new Client(config);
}

3、第二个方法：返回指定的记录ID（RecordId）

在阿里云的SDK中，对解析记录进行修改和删除时，都需要传入 RecordId 这个参数，所以提前写一个获取记录ID的方法。

/**
* <p>
* 返回指定主机记录的ID，不存在时返回null
* </p>
*
* @param DomainName
* @param RR 记录名称
* @return
*/
private String getRecId(Client client, String DomainName, String RR){
String recId = null;
try {
DescribeDomainRecordsRequest request = new DescribeDomainRecordsRequest();
request.setDomainName(DomainName);
request.setRRKeyWord(RR);
DescribeDomainRecordsResponse response = client.describeDomainRecords(request);
if(response.getBody().getTotalCount() > 0){
List<DescribeDomainRecordsResponseBodyDomainRecordsRecord> recs = response.getBody().getDomainRecords().getRecord();
for(DescribeDomainRecordsResponseBodyDomainRecordsRecord rec: recs){
if(rec.getRR().equalsIgnoreCase(RR)){
recId = rec.getRecordId();
break;
}
}
}
} catch (Exception e) {
}
return recId;
}

4、第三个方法：添加或修改指定的记录

方便起见，这里我将添加和修改集成到了一个方法，相当于SaveOrUpdate。

/**
* <p>
* 添加或修改解析记录
* </p>
*
* @param DomainName 域名
* @param RR 记录名称
* @param Type 记录类型（A、AAAA、MX、TXT、CNAME）
* @param Value 记录值
*/
public void update(String DomainName, String RR, String Type, String Value){
try {
if(EStr.isEmpty(DomainName)) throw new RuntimeException("域名（DomainName）为空！");
if(EStr.isEmpty(RR)) throw new RuntimeException("主机记录（RR）为空！");
if(EStr.isEmpty(Type)) throw new RuntimeException("记录类型（Type）为空！");
if(EStr.isEmpty(Value)) throw new RuntimeException("记录值（Value）为空！");
Client client = createClient();
String recId = getRecId(client, DomainName, RR);
if(EStr.isNull(recId)){ //添加
AddDomainRecordRequest request = new AddDomainRecordRequest();
request.setDomainName(DomainName);
request.setRR(RR);
request.setType(Type);
request.setValue(Value);
AddDomainRecordResponse response = client.addDomainRecord(request);
recId = response.getBody().getRecordId();
}else{ //修改
UpdateDomainRecordRequest request = new UpdateDomainRecordRequest();
request.setRecordId(recId);
request.setRR(RR);
request.setType(Type);
request.setValue(Value);
UpdateDomainRecordResponse response = client.updateDomainRecord(request);
recId =
ad8
response.getBody().getRecordId();
}
renderJson(Result.success("recId", recId));
} catch (Exception e) {
renderJson(Result.fail(e.getMessage()));
}
}

5、第四个方法：删除指定的记录

这个很简单，根据查找到的RecordId直接删除即可。

/**
* <p>
* 删除记录
* </p>
*
* @param DomainName
* @param RR
*/
public void remove(String DomainName, String RR){
try {
if(EStr.isEmpty(DomainName)) throw new RuntimeException("域名（DomainName）为空！");
if(EStr.isEmpty(RR)) throw new RuntimeException("主机记录（RR）为空！");
Client client = createClient();
String recId = getRecId(client, DomainName, RR);
if(EStr.isNull(recId)){
renderJson(Result.success("recId", null));
}else{
DeleteDomainRecordRequest request = new DeleteDomainRecordRequest();
request.setRecordId(recId);
DeleteDomainRecordResponse response = client.deleteDomainRecord(request);
renderJson(Result.success("recId", response.getBody().getRecordId()));
}
} catch (Exception e) {
renderJson(Result.fail(e.getMessage()));
}
}
