Fabric-java-sdk 開通TLS時訪問Fabric網路

2020-11-01 13:32:46 前端設計

Fabric-java-sdk 1.4.1 TLS 通信 訪問Fabric網路

1.組態檔部分

  • Fabric 1.4網路，采用solo模式，背書策略是： ‘OR (’’‘Org1MSP.peer’’’,’’‘Org2MSP.peer’’’)’

不采用 tls通信：
Peer0_Org1_Name=“peer0.org1.example.com”;
Peer0_Org1_Url=“grpc://localhost:7051”;
OrdererName=“orderer.example.com”;
OrdererUrl=“grpcs://localhost:7050”;
采用 tls通信：
Peer0_Org1_Name=“peer0.org1.example.com”;
Peer0_Org1_Url=“grpcs://localhost:7051”;
OrdererName=“orderer.example.com”;
OrdererUrl=“grpcs://localhost:7050”;

整個組態檔ConfigUrl.java如下：

}

2.在這個Fabric網路中 orderer2.example.com,
orderer3.example.com,orderer4.example.com,orderer4.example.com這四個排序服務節點都沒有用的，只用到了orderer.example.com,crypto-config目錄如下,：
在這個Fabric網路中orderer2.example.com,orderer3.example.com,orderer4.example.com,orderer4.example.com這四個排序服務節點都沒有用的，只用到了orderer，example.com

2. 呼叫鏈碼查詢資訊

QueryChaincodeOpenTls.java代碼如下：

package org.edu.fabric.sdk.testtls;

import org.edu.fabric.sdk.config.ConfigUrl;
import org.edu.fabric.sdk.config.FactoryConfig;
import org.edu.fabric.sdk.impl.UserImpl;

import org.hyperledger.fabric.sdk.security.CryptoSuite;

import java.io.*;
import java.lang.reflect.InvocationTargetException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.Collection;

public class QueryChaincode {
    public static void main(String args[]) throws IOException, ClassNotFoundException, IllegalAccessException, InvocationTargetException, InvalidArgumentException, InstantiationException, NoSuchMethodException, CryptoException, ProposalException, TransactionException {
        //這里的userContext使用的是cryptogen二進制檔案生成的組織org1.example.com的管理員：Admin@org1.example.com，此外也可以使用CA節點重新去生成userContext
        UserImpl userContext=new UserImpl();
        userContext.setName(ConfigUrl.Admin);
        userContext.setMspId(ConfigUrl.Org1_Msp);
        Enrollment enrollment= FactoryConfig.getEnrollment(ConfigUrl.Org1_Usr_Admin_Cert,ConfigUrl.Org1_Usr_Admin_PK_Base_Path);

        CryptoSuite cryptoSuite=CryptoSuite.Factory.getCryptoSuite();
        HFClient hfClient=HFClient.createNewInstance();
        hfClient.setCryptoSuite(cryptoSuite);
        hfClient.setUserContext(userContext);
        //create peer ,orderer,Eventhub
        String peerCert=new String(Files.readAllBytes(Paths.get("/root/IdeaProjects/fabricProject/src/main/resources/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.crt")),"UTF-8");

        Properties peerProperties=new Properties();
        peerProperties.put("pemBytes",peerCert.getBytes());
        peerProperties.setProperty("sslProvider","openSSL");
        peerProperties.setProperty("negotiationType","TLS");
        peerProperties.setProperty("hostnameOverride", ConfigUrl.Peer0_Org1_Name);
        /*
        peerProperties.setProperty("clientKeyFile","");
        peerProperties.setProperty()*/
        Peer peer=hfClient.newPeer(ConfigUrl.Peer0_Org1_Name,ConfigUrl.Peer0_Org1_Url,peerProperties);

        String ordererCert=new String(Files.readAllBytes(Paths.get("/root/IdeaProjects/fabricProject/src/main/resources/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/server.crt")),"UTF-8");
        Properties ordererProperties=new Properties();
        ordererProperties.put("pemBytes",ordererCert.getBytes());
        ordererProperties.setProperty("sslProvider","openSSL");
        ordererProperties.setProperty("negotiationType","TLS");
        ordererProperties.setProperty("hostnameOverride",ConfigUrl.OrdererName);
        Orderer orderer=hfClient.newOrderer(ConfigUrl.OrdererName,ConfigUrl.OrdererUrl,ordererProperties);
        EventHub eventHub=hfClient.newEventHub(ConfigUrl.Peer0_Org1_Name,"grpcs://localhost:7053",peerProperties);

        Channel channel=hfClient.newChannel(ConfigUrl.ChannelName);
        channel.addPeer(peer);
        channel.addOrderer(orderer);
        channel.addEventHub(eventHub);
        channel.initialize();

        //create
        QueryByChaincodeRequest queryByChaincodeRequest=hfClient.newQueryProposalRequest();
        ChaincodeID chaincodeId=ChaincodeID.newBuilder().setName("mycc").build();
        queryByChaincodeRequest.setChaincodeID(chaincodeId);
        queryByChaincodeRequest.setFcn("query");
        queryByChaincodeRequest.setArgs(new String[]{"a"});
        Collection<ProposalResponse> responses=channel.queryByChaincode(queryByChaincodeRequest);

        for(ProposalResponse res:responses){
            if(res.getStatus().getStatus()!=200){
                System.out.println("query fail:"+res.getMessage());
            }else{
                System.out.println(res.getStatus().toString());

                System.out.println(new String(mes));

            }
        }
    }
    }

4.相關.java檔案

UserImpl.java檔案如下：

package org.edu.fabric.sdk.impl;

import org.hyperledger.fabric.sdk.Enrollment;
import org.hyperledger.fabric.sdk.User;

import java.io.Serializable;
import java.util.Set;

public class UserImpl implements User, Serializable {
    private String name;
    private Set<String>roles;
    private String account;
    private String affiliation;
    private Enrollment enrollment;
    public  UserImpl(){ }

    public UserImpl(String name, Enrollment enrollment, String mspId) {
        this.name = name;
        this.enrollment = enrollment;
        this.mspId = mspId;
    }

    public void setName(String name) {
        this.name = name;
    }

    public void setRoles(Set<String> roles) {
        this.roles = roles;
    }

    public void setAccount(String account) {
        this.account = account;
    }

    public void setAffiliation(String affiliation) {
        this.affiliation = affiliation;
    }

    public void setEnrollment(Enrollment enrollment) {
        this.enrollment = enrollment;
    }

    public void setMspId(String mspId) {
        this.mspId = mspId;
    }

    private String mspId;
    @Override
    public String getName() {
        return this.name;
    }

    @Override
    public Set<String> getRoles() {
        return this.roles;
    }

    @Override
    public String getAccount() {
        return this.account;
    }

    @Override
    public String getAffiliation() {
        return this.affiliation;
    }

    @Override
    public Enrollment getEnrollment() {
        return this.enrollment;
    }

    @Override
    public String getMspId() {
        return this.mspId;
    }
}

FactoryConfig.java檔案如下：

package org.edu.fabric.sdk.config;

import org.edu.fabric.sdk.impl.EnrollmentImpl;
import org.hyperledger.fabric.sdk.Enrollment;
import org.hyperledger.fabric.sdk.exception.CryptoException;
import org.hyperledger.fabric.sdk.security.CryptoPrimitives;

import java.io.*;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.security.PrivateKey;

public  class FactoryConfig {
    public  static Enrollment getEnrollment(String certPath,String pkBasePath) throws IOException, IllegalAccessException, InstantiationException, ClassNotFoundException, CryptoException {
        //get cert
        byte [] certBytes= Files.readAllBytes(Paths.get(certPath));
        //get pk
        File[] files=new File(pkBasePath).listFiles();
        String certName=files[0].getName();
        String pkPath=pkBasePath+File.separator+certName;
        byte [] pkBytes=Files.readAllBytes(Paths.get(pkPath));
        CryptoPrimitives cryptoPrimitives=new CryptoPrimitives();
        PrivateKey PK=cryptoPrimitives.bytesToPrivateKey(pkBytes);
        return new EnrollmentImpl(PK,new String(certBytes,"UTF-8"));
    }

}

EnrollmentImpl.java檔案如下：

package org.edu.fabric.sdk.impl;

import org.hyperledger.fabric.sdk.Enrollment;

import java.security.PrivateKey;

public class EnrollmentImpl implements Enrollment {
    private PrivateKey privateKey;
    private String cert;

    public EnrollmentImpl() {
    }

    public EnrollmentImpl(PrivateKey privateKey, String cert) {
        this.privateKey = privateKey;
        this.cert = cert;
    }

    @Override
    public PrivateKey getKey() {
        return this.privateKey;
    }

    @Override
    public String getCert() {
        return this.cert;
    }

    public void setPrivateKey(PrivateKey privateKey) {
        this.privateKey = privateKey;
    }

    public void setCert(String cert) {
        this.cert = cert;
    }
}
