fabric-sdk-java 在 开启了TLS 情况下如何进行invoke query，研究了很久，终于弄通了fabric-sdk-java在启用TLS的情况下，进行简单调用的正确姿势。特别写篇博客分享一下
先提供一下自己写好的demo,
下载示例demo
提醒: demo里的util.java有错误, 需要把ECDSA替换成EC, 在第136行 , 下面附的代码里是对的
详细描述写在下面
一、网络环境
首先呢，我们需要启动一个网络环境。出于简单，直接上官网的byfn网络，如果你还没有搭建好一套基础的网络环境，请移步hyperledger-fabric网络环境搭建。
这里启动的方式稍有不同，因为我们要启动一个带有ca服务的网络，也就是e2e网络.启动命令是
./byfn.sh up -f docker-compose-e2e.yaml二、代码部分
1、复制证书文件。
网络启动后，在first-network文件夹下面会生成crypto-config文件，将改文件拷贝到本地，在workspace所在盘的根目录下创建data文件夹，将crypto-config放到data目录下，路径如图所示:
crypto-config是执行invoke和query所需的文件, 如果你还想要试一试创建通道,实例化链码等 , 你还需要把chaincode和channel-artifacts文件夹拷贝过来 ,
如果你不太清楚，看一下下面配置文件的路径设置就可以了。
2、修改基础配置文件
package org.app.config;
import java.io.File;
public class Config {
public static final String baseUrl ="106.12.94.62";
public static final String grpc="grpcs://";
public static final String CA_ORG1_URL = "https://" + baseUrl + ":7054";
public static final String CA_ORG2_URL = "https://" + baseUrl + ":8054";
public static final String ORG1_MSP = "Org1MSP";
public static final String ORG1 = "org1";
public static final String ORG2_MSP = "Org2MSP";
public static final String ORG2 = "org2";
public static final String CA1NAME = "ca-org1";
public static final String CA2NAME = "ca-org2";
public static final String ADMIN = "admin";
public static final String ADMIN_PASSWORD = "adminpw";
public static final String CHANNEL_CONFIG_PATH = "config/channel.tx";
public static final String ORG1_USR_BASE_PATH =File.separator+"data"+File.separator+ "crypto-config" + File.separator + "peerOrganizations" + File.separator
+ "org1.example.com" + File.separator + "users" + File.separator + "[email protected]"
+ File.separator + "msp";
public static final String ORG2_USR_BASE_PATH =File.separator+"data"+File.separator+ "crypto-config" + File.separator + "peerOrganizations" + File.separator
+ "org2.example.com" + File.separator + "users" + File.separator + "[email protected]"
+ File.separator + "msp";
public static final String CA1_TLSFILE = File.separator+"data"+File.separator+ "crypto-config" + File.separator + "peerOrganizations" + File.separator
+"org1.example.com"+File.separator+ "ca"+ File.separator+"ca.org1.example.com-cert.pem";
public static final String ORG1_PER1_CAFILE=File.separator+"data"+File.separator+ "crypto-config" + File.separator + "peerOrganizations" + File.separator
+ "org1.example.com" + File.separator + "tlsca" + File.separator + "tlsca.org1.example.com-cert.pem";
public static final String ORG2_PER1_CAFILE=File.separator+"data"+File.separator+ "crypto-config" + File.separator + "peerOrganizations" + File.separator
+ "org2.example.com" + File.separator + "tlsca" + File.separator + "tlsca.org2.example.com-cert.pem";
public static final String ORDER_CAFILE=File.separator+"data"+File.separator+ "crypto-config" + File.separator + "ordererOrganizations" + File.separator
+ "example.com" + File.separator + "tlsca" + File.separator + "tlsca.example.com-cert.pem";
public static final String ORG1_USR_ADMIN_PK = ORG1_USR_BASE_PATH + File.separator + "keystore";
public static final String ORG1_USR_ADMIN_CERT = ORG1_USR_BASE_PATH + File.separator + "admincerts";
public static final String ORG2_USR_ADMIN_PK = ORG2_USR_BASE_PATH + File.separator + "keystore";
public static final String ORG2_USR_ADMIN_CERT = ORG2_USR_BASE_PATH + File.separator + "admincerts";
public static final String ORDERER_URL = grpc+ baseUrl + ":7050";
public static final String ORDERER_NAME = "orderer.example.com";
public static final String CHANNEL_NAME = "mychannel";
public static final String ORG1_PEER_0 = "peer0.org1.example.com";
public static final String ORG1_PEER_0_URL = grpc + baseUrl+ ":7051";
public static final String ORG1_PEER_1 = "peer1.org1.example.com";
public static final String ORG1_PEER_1_URL = grpc + baseUrl+ ":8051";
public static final String ORG2_PEER_0 = "peer0.org2.example.com";
public static final String ORG2_PEER_0_URL =grpc + baseUrl+ ":9051";
public static final String ORG2_PEER_1 = "peer1.org2.example.com";
public static final String ORG2_PEER_1_URL = grpc + baseUrl+ ":10051";
public static final String CHAINCODE_ROOT_DIR = "chaincode";
public static final String CHAINCODE_1_NAME = "mycc";
public static final String CHAINCODE_1_PATH = "github.com/fabcar";
public static final String CHAINCODE_1_VERSION = "1";
}
项目运行用用到的配置文件，通常你只需要修改baseUrl，如果你运行的网络和我的不一样，那就不好说了，看着改吧， 主要是证书路径，部分要改对，另外这里的证书路径和1中你存放的证书路径要一致，如果前面你放到其他目录了， 这里把路径该对就行了。
三、执行方法
1、执行QueryChaincode
public class QueryChaincode {
private static final byte[] EXPECTED_EVENT_DATA = "!".getBytes(UTF_8);
private static final String EXPECTED_EVENT_NAME = "event";
static String getPEMStringFromPrivateKey(PrivateKey privateKey) throws IOException {
StringWriter pemStrWriter = new StringWriter();
PEMWriter pemWriter = new PEMWriter(pemStrWriter);
pemWriter.writeObject(privateKey);
pemWriter.close();
return pemStrWriter.toString();
}
public static HFCAClient enableTLS(HFCAClient hfcaclient ,String uesrName , String userpasswd ,String orgName ,String caHsotIp) {
final EnrollmentRequest enrollmentRequestTLS = new EnrollmentRequest();
enrollmentRequestTLS.addHost(caHsotIp);
enrollmentRequestTLS.setProfile("tls");
try {
final Enrollment enroll =hfcaclient.enroll(uesrName, userpasswd,enrollmentRequestTLS);
final String tlsCertPEM = enroll.getCert();
final String tlsKeyPEM = getPEMStringFromPrivateKey(enroll.getKey());
final Properties tlsProperties = new Properties ();
tlsProperties.put("clientKeyBytes", tlsKeyPEM.getBytes(UTF_8));
tlsProperties.put("clientCertBytes", tlsCertPEM.getBytes(UTF_8));
} catch (EnrollmentException | InvalidArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return hfcaclient;
}
public static void main(String args[]) {
try {
Util.cleanUp();
UserContext adminUser = new UserContext();
adminUser.setName(Config.ADMIN);
adminUser.setAffiliation(Config.ORG1);
adminUser.setMspId(Config.ORG1_MSP);
File f = new File (Config.CA1_TLSFILE);
String certficate = new String (IOUtils.toByteArray(new FileInputStream(f)),"UTF-8");
Properties properties = new Properties();
properties.put("pemBytes", certficate.getBytes());
properties.setProperty("pemFile", f.getAbsolutePath());
properties.setProperty("allowAllHostNames", "true");
CAClient caclient=new CAClient(Config.CA1NAME, Config.CA_ORG1_URL, properties);
caclient.setAdminUserContext(adminUser);
adminUser = caclient.enrollAdminUserTLS("admin", "adminpw");
FabricClient fabClient = new FabricClient(adminUser);
ChannelClient channelClient = fabClient.createChannelClient(Config.CHANNEL_NAME);
Channel channel = channelClient.getChannel();
Properties properties1 = Util.gete2ePro("peer",Config.ORG1_PEER_0);
Peer peer = fabClient.getInstance().newPeer(Config.ORG1_PEER_0, Config.ORG1_PEER_0_URL,properties1);
EventHub eventHub = fabClient.getInstance().newEventHub("eventhub01",Config.grpc+ Config.baseUrl+":7053");
Properties orderPro = Util.gete2ePro("orderer", Config.ORDERER_NAME);
Orderer orderer = fabClient.getInstance().newOrderer(Config.ORDERER_NAME, Config.ORDERER_URL,orderPro);
channel.addPeer(peer);
channel.addOrderer(orderer);
channel.initialize();
Logger.getLogger(QueryChaincode.class.getName()).log(Level.INFO, "Querying ...");
Collection<ProposalResponse> responsesQuery = channelClient.queryByChainCode("mycc", "query", new String[] {"b"});
for (ProposalResponse pres : responsesQuery) {
String stringResponse = new String(pres.getChaincodeActionResponsePayload());
Logger.getLogger(QueryChaincode.class.getName()).log(Level.INFO, stringResponse);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}网络相同情况下，可以直接执行， 如果真的需要改，那就是 用户名密码，还有链码名mycc，跟方法名query，还有参数a可能会需要改。
2、执行InvokeChaincode
public class InvokeChaincode {
private static final byte[] EXPECTED_EVENT_DATA = "!".getBytes(UTF_8);
private static final String EXPECTED_EVENT_NAME = "event";
public static void main(String args[]) {
try {
Util.cleanUp();
UserContext adminUser = new UserContext();
adminUser.setName(Config.ADMIN);
adminUser.setAffiliation(Config.ORG1);
adminUser.setMspId(Config.ORG1_MSP);
File f = new File (Config.CA1_TLSFILE);
String certficate = new String (IOUtils.toByteArray(new FileInputStream(f)),"UTF-8");
Properties properties = new Properties();
properties.put("pemBytes", certficate.getBytes());
properties.setProperty("pemFile", f.getAbsolutePath());
properties.setProperty("allowAllHostNames", "true");
CAClient caclient=new CAClient(Config.CA1NAME, Config.CA_ORG1_URL, properties);
caclient.setAdminUserContext(adminUser);
adminUser = caclient.enrollAdminUserTLS("admin", "adminpw");
FabricClient fabClient = new FabricClient(adminUser);
ChannelClient channelClient = fabClient.createChannelClient(Config.CHANNEL_NAME);
Channel channel = channelClient.getChannel();
Properties properties1 = Util.gete2ePro("peer",Config.ORG1_PEER_0);
Peer peer = fabClient.getInstance().newPeer(Config.ORG1_PEER_0, Config.ORG1_PEER_0_URL,properties1);
Properties properties2 = Util.gete2ePro("peer",Config.ORG2_PEER_0);
Peer peer2 = fabClient.getInstance().newPeer(Config.ORG2_PEER_0, Config.ORG2_PEER_0_URL,properties2);
EventHub eventHub = fabClient.getInstance().newEventHub("eventhub01", Config.grpc+Config.baseUrl+":7053",properties1);
// EventHub eventHub2 = fabClient.getInstance().newEventHub("eventhub02", "grpcs://"+Config.baseUrl+":9053");
Properties orderPro = Util.gete2ePro("orderer",Config.ORDERER_NAME);
Orderer orderer = fabClient.getInstance().newOrderer(Config.ORDERER_NAME, Config.ORDERER_URL,orderPro);
channel.addPeer(peer);
channel.addPeer(peer2);//背书策略为OR的话不需要添加 peer2
channel.addEventHub(eventHub);
channel.addOrderer(orderer);
channel.initialize();
TransactionProposalRequest request = fabClient.getInstance().newTransactionProposalRequest();
ChaincodeID ccid = ChaincodeID.newBuilder().setName(Config.CHAINCODE_1_NAME).build();
request.setChaincodeID(ccid);
request.setFcn("invoke");
String[] arguments = { "a", "b", "11" };
request.setArgs(arguments);
request.setProposalWaitTime(1000);
Map<String, byte[]> tm2 = new HashMap<>();
tm2.put("HyperLedgerFabric", "TransactionProposalRequest:JavaSDK".getBytes(UTF_8));
tm2.put("method", "TransactionProposalRequest".getBytes(UTF_8));
tm2.put("result", ":)".getBytes(UTF_8));
tm2.put(EXPECTED_EVENT_NAME, EXPECTED_EVENT_DATA);
request.setTransientMap(tm2);
Collection<ProposalResponse> responses = channelClient.sendTransactionProposal(request);
for (ProposalResponse res: responses) {
Status status = res.getStatus();
Logger.getLogger(InvokeChaincode.class.getName()).log(Level.INFO,"Invoked on "+Config.CHAINCODE_1_NAME + ". Status - " + status);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}同样，方法名，参数看看是否需要修改，希望你可以成功运行。
其他的像创建通道, 实例化链代码等方法 , demo里也都有示例, 不过要想要运行成功 , 还需要你修改配置文件里的路径 , 摸索试试吧 .
