调用示例

Java-sdk 调用示例

// 初始化SDKTDCSDK tdcsdk = new TDCSDK("/root/test-tdc-sdk-conf/conf.yaml");// 创建名为“tiger01”的集合String collectionIndex = "tiger01";String txid = tdcsdk.createNFTCollection(collectionIndex);System.out.println("Create collection txid: "+txid);// 生成数字资产meta信息Metadata md = tdcsdk.newImageMetadata(new String("image bytes").getBytes(),        "tigerImage","http://obs.huawei.com/1/tiger","description",1);// 铸造数字资产MintResp mintResp = tdcsdk.nft721.mint(collectionIndex,"1",md);System.out.println("Mint nft:"+mintResp.getNft());System.out.println("Mint txid:"+mintResp.getTxid());// 生成新的用户信息，包括证书，私钥和地址IdentityInfo receiver = tdcsdk.generateIdentity(Tools.ECDSA_ALGORITHM,"test1");System.out.println("cert: "+receiver.getCert());System.out.println("sk: "+receiver.getKey());System.out.println("addr: "+receiver.getAddress());// 查询数字资产所有者String owner = tdcsdk.nft721.ownerOf(collectionIndex,"1");System.out.println("collection:"+collectionIndex+", token:1 owner is "+owner);// 数字资产转移String transferTxid = tdcsdk.nft721.transferFrom(collectionIndex,owner,receiver.getAddress(),"1");System.out.println("Transfer txid:"+transferTxid);// 批量铸造数字资产String tx = tdcsdk.nft1155.batchMint(collectionIndex, new BatchMintData("10000", "50", md));System.out.println("BatchMint txid: "+tx);// 铸造数字资产MintResp mintResp2 = tdcsdk.nft721.mint(collectionIndex, "2", md);System.out.println("Mint nft:"+mintResp2.getNft());System.out.println("Mint txid:"+mintResp2.getTxid());// 查询数字资产所有者String ownerOfTokenID = tdcsdk.nft721.ownerOf(collectionIndex,"2");System.out.println("collection:"+collectionIndex+", token:2 owner is "+ownerOfTokenID);// 铸造可组合资产MintResp mintComposeResp = tdcsdk.nft998.mint(collectionIndex, "10", md);System.out.println("Mint of composable asset nft:"+mintComposeResp.getNft());System.out.println("Mint of composable asset txid:"+mintComposeResp.getTxid());// 加入可组合资产String getChildTxid = tdcsdk.nft998.getChild(ownerOfTokenID, collectionIndex, "10", collectionIndex, "2");System.out.println("GetChild txid: "+getChildTxid);// 切换成新的用户身份tdcsdk.switchIdentityWithPem(Tools.ECDSA_ALGORITHM,receiver.getCert(),receiver.getKey());// 其他业务调用...
