BSN-DID集中部署了DID合约，划分了一片存储空间，专门用来
存储用户凭证内容，称为隐私数据存储区
。同时部署了服务，对外提供单次授权、单次访问、访问者身份验证等服务，保证了证书的安全可控。
本文就是针对隐私数据操作函数进行代码验证分析。
主题4 ：存储、删除、修改、查询资源，创建授权， 查询权限，解密资源， 内容来源于帮助手册的14.4.4 隐私区域。
1 通过公钥注册Hub用户
方法名：
registerHubByDid(String did)
方法描述：
通过DID标识符注册Hub，成功则返回用户在Hub内的ID。
2 通过DID注册Hub用户
方法名：
registerHub(String id, String publicKey, CryptoType cryptoType)
方法描述： 通过公钥注册Hub，支持用户自定义ID，注册成功便返回用户在Hub内的ID。
【说明】手册中的参数列表是错误的，正确的用法请看下面代码。
如果指定了did，注册后的uid就是did。
如果没有指定did，注册后的uid是个16进制字符串，怎么计算出来的不知道！！
public static void registerHubtTest() {
DidDataWrapper didDataWrapper = didClient.createDid(true);
RegisterHubResult registerHubResult1 = didClient.registerHub(didDataWrapper.getDid(), didDataWrapper.getAuthKeyInfo().getPublicKey(),CryptoType.ECDSA);
System.out.println(JSONObject.toJSONString(registerHubResult1));
System.out.println(registerHubResult1.isSuccess());
RegisterHubResult registerHubResult2 = didClient.registerHubByDid("did:bsn:2nbUugNA1D7M4ZRxsMqqYYYFkX5W");
System.out.println(JSONObject.toJSONString(registerHubResult2));
}
运行结果:
{"success":true,"uid":"did:bsn:3G12xevH5UEBrpw4Yn91r869nXS"}
true
{"success":true,"uid":"did:bsn:2nbUugNA1D7M4ZRxsMqqYYYFkX5W"}
public static void registerHubByPublicKeyTest() {

try {
authKeyPair = ECDSAUtils.createKey();
System.out.println("PublicKey="+authKeyPair.getPublicKey());
System.out.println("PrivateKey="+authKeyPair.getPrivateKey());
} catch (Exception e) {
throw new RuntimeException(e);
}
RegisterHubResult registerHubResult = didClient.registerHub(authKeyPair.getPublicKey(),CryptoType.ECDSA);
System.out.println(JSONObject.toJSONString(registerHubResult));
System.out.println(registerHubResult.isSuccess());
}
运行结果：

3 存储资源
方法名：
saveResource(SaveResource saveResource)
方法描述：
向Hub内存储资源。如果用户自己存储则uid和ownerUid应一致，此时不需要创建权限直接调用即可；
如果是发证方在签发完凭证后替用户存储，则uid应为发证方，ownerUid应为用户，此时必须是用户已经为其创建了“WRITE”权限，否则将存储失败。
public static void saveResourceECDSATest() {
DidDataWrapper didDataWrapper = didClient.createDid(true);
RegisterHubResult registerHubResult = didClient.registerHub(didDataWrapper.getDid(), didDataWrapper.getAuthKeyInfo().getPublicKey(),didClient.getHubCryptoType());
SaveResource saveResource = new SaveResource();
saveResource.setUid(didDataWrapper.getDid());
saveResource.setContent("aaaaaaaaaaaaa");
saveResource.setGrant(Operation.WRITE);
saveResource.setOwnerUid(didDataWrapper.getDid());
saveResource.setPrivateKey(didDataWrapper.getAuthKeyInfo().getPrivateKey());
SaveResourceResult saveResourceResult = didClient.saveResource(saveResource);
System.out.println("saveResource = "+ JSONObject.toJSONString(saveResource));
System.out.println("=================="+JSONObject.toJSONString(saveResourceResult));
System.out.println(saveResourceResult.getEncryptKey());
System.out.println(saveResourceResult.getUrl());
}
运行结果：
==================
saveResource = {
"content":"aaaaaaaaaaaaa",
"grant":"WRITE",
"ownerUid":"did:bsn:3fHe28XNL23q61mMnJQ9a9EXmXzs",

"uid":"did:bsn:3fHe28XNL23q61mMnJQ9a9EXmXzs"
}
saveResourceResult =
{

}
注意结果url的前半截就是uid， encryptKey就是加密后的密文密钥。
public static void saveResourceTest2() {
com.reddate.did.sdk.param.KeyPair keyPair = Secp256Util.createKeyPair(CryptoType.ECDSA);
String userId = Secp256Util.getAddress(CryptoType.ECDSA, keyPair.getPrivateKey());
System.out.println("userId = "+userId);
RegisterHubResult registerHubResult = didClient.registerHub(userId, keyPair.getPublicKey(),CryptoType.ECDSA);
SaveResource saveResource = new SaveResource();
saveResource.setUid(userId);
saveResource.setContent("aaaaaaaaaaaaa");
saveResource.setGrant(Operation.WRITE);
saveResource.setOwnerUid(userId);
saveResource.setPrivateKey(keyPair.getPrivateKey());
SaveResourceResult saveResourceResult = didClient.saveResource(saveResource);
System.out.println("saveResource = "+ JSONObject.toJSONString(saveResource));
System.out.println("=================="+JSONObject.toJSONString(saveResourceResult));
System.out.println("saveResourceResult = "+JSONObject.toJSONString(saveResourceResult));

方法描述：
使用获取资源接口返回的密文密钥对获取资源接口返回的密文资源内容进行解密，得到明文资源内容。
public static void getResourceECDSATest() {
DidDataWrapper didDataWrapper = didClient.createDid(true);
RegisterHubResult registerHubResult = didClient.registerHub(didDataWrapper.getDid(), didDataWrapper.getAuthKeyInfo().getPublicKey(),didClient.getHubCryptoType());

System.out.println("=================="+ JSONObject.toJSONString(saveResourceResult));
QueryResourceResp queryResourceResp = didClient.getResource(didDataWrapper.getDid(), didDataWrapper.getAuthKeyInfo().getPrivateKey(), saveResourceResult.getUrl());
System.out.println("=================="+JSONObject.toJSONString(queryResourceResp));
String content2 = didClient.decrypt(queryResourceResp.getContent(), queryResourceResp.getKey(), didDataWrapper.getAuthKeyInfo().getPrivateKey());
System.out.println(content2);
}
运行结果：

方法描述：
资源的Owner可调，对Hub内的某个资源进行删除。
public static void deleteResourceECDSATest() {
DidDataWrapper didDataWrapper = didClient.createDid(true);
RegisterHubResult registerHubResult = didClient.registerHub(didDataWrapper.getDid(), didDataWrapper.getAuthKeyInfo().getPublicKey(),didClient.getHubCryptoType());
SaveResource saveResource = new SaveResource();
saveResource.setUid(didDataWrapper.getDid());
saveResource.setContent("aaaaaaaaaaaaa");

queryResourceResp = didClient.getResource(didDataWrapper.getDid(), didDataWrapper.getAuthKeyInfo().getPrivateKey(), saveResourceResult.getUrl());
System.out.println("====== after delete ======="+JSONObject.toJSONString(queryResourceResp));

6 创建权限
方法名： createPermission(CreatePermission createPermission)
方法描述：资源的Owner为第三方创建访问Hub内资源的权限。WRITE表示代存资源、UPDATE表示代更新资源、READ表示读取资源。

CreatePermission createPermission = new CreatePermission();
createPermission.setUid(didDataWrapper.getDid()); //授权者
createPermission.setUrl(null); //资源存储的Url路径，WRITE权限可为空，READ/UPDATE权限必填
createPermission.setPrivateKey(didDataWrapper.getAuthKeyInfo().getPrivateKey());
createPermission.setGrant(Operation.WRITE); //权限

QueryResourceResp queryResourceResp = didClient.getResource(didDataWrapper2.getDid(), didDataWrapper2.getAuthKeyInfo().getPrivateKey(), createPermissionResp.getUrl());
System.out.println("=================="+JSONObject.toJSONString(queryResourceResp));
}
运行结果： DID2获得了资源内容。

上述访问后，再次读取资源必然失败，因为授权是一次性的， 访问后就无效了。想要再次访问必须重新授权。

RegisterHubResult registerHubResult = didClient.registerHub(didDataWrapper.getDid(), didDataWrapper.getAuthKeyInfo().getPublicKey(),didClient.getHubCryptoType());
DidDataWrapper didDataWrapper2 = didClient.createDid(true);
RegisterHubResult registerHubResult2 = didClient.registerHub(didDataWrapper2.getDid(), didDataWrapper2.getAuthKeyInfo().getPublicKey(),didClient.getHubCryptoType());
CreatePermission createPermission = new CreatePermission();

createPermission.setGrant(Operation.WRITE);
createPermission.setGrantUid(didDataWrapper2.getDid());
createPermission.setGrantPublicKey(didDataWrapper2.getAuthKeyInfo().getPublicKey());
CreatePermissionResp createPermissionResp = didClient.createPermission(createPermission);
System.out.println("=================="+JSONObject.toJSONString(createPermissionResp));
//查询did2用户的授权记录
QueryGrantedPermission queryPermission = new QueryGrantedPermission();
