第一部分:新功能介紹html
這是一種經過使用零知識證實來保持身份匿名和不可連接的方法。工具idexmigen能夠在測試環境中生成Identity Mixer憑證。java
零知識證實,英文名爲Zero-Knowledge Proof,是由S.Goldwasser、S.Micali以及C.Rackoff在20世紀80年代初提出的。它指的是證實者(被驗證者)可以在不向驗證者提供任何有用的信息的狀況下,使驗證者相信某個論斷是正確的。node
零知識證實實質上是一種涉及兩方或更多方的協議,即兩方或更多方完成一項任務所需採起的一系列步驟。python
Idemix是一個加密協議套件,它提供強大的身份驗證以及隱私保護功能,如匿名,無需揭示交易者身份便可進行交易,以及不可連接性,即單個身份發送多個交易的能力,而不會泄露交易是經過相同的身份發送的。linux
Idemix流中涉及三個參與者:用戶,發行者和 驗證者。nginx
發行者證實將一組用戶的屬性以數字證書的形式發佈,如下稱爲「憑證」。git
用戶稍後生成擁有憑證的「 零知識證實 」,而且可以選擇性地公開用戶選擇顯示的屬性。它不會向驗證者,發行者或任何其餘人顯示其餘信息。github
要在Hyperledger Fabric中使用Idemix,須要如下三個基本步驟:golang
發行者:Fabric CA 或者 idemixgendocker
驗證者:Idemix MSP
用戶 :java SDK類org.hyperledger.fabric_ca.sdk.HFCAClient
(例如:IdemixEnrollment idemixEnrollment = hfcaClient.idemixEnroll(x509enrollment, "idemixMSPID1"))
Fabric-ca在Ubuntu和Centos上面的安裝
第一步:安裝系統組件包
sudo apt install libtool libltdl-dev
若是在Centos上面安裝,則須要執行命令 yum install libtool libltdl-dev,其餘的步驟相同。
第二步:下載源代碼並編譯
cd $GOPATH/src/github.com/hyperledger
git clone http://gerrit.hyperledger.org/r/fabric-ca
cd $GOPATH/src/github.com/hyperledger/fabric-ca
查看版本:
cd fabric-ca/
git branch -a (切換如:git checkout release-1.3)
make fabric-ca-server
報錯:
[root@localhost fabric-ca]# make fabric-ca-server
Building fabric-ca-server in bin directory ...
# github.com/hyperledger/fabric-ca/vendor/github.com/miekg/pkcs11
vendor/github.com/miekg/pkcs11/pkcs11.go:26:18: fatal error: ltdl.h: No such file or directory
#include <ltdl.h>
^
compilation terminated.
make: *** [bin/fabric-ca-server] 錯誤 2
解決:
若是在ubunt操做系統中,只需安裝:apt install libltdl3-dev
若是在centos操做系統中,只需安裝:yum install libtool-ltdl-devel
make fabric-ca-server
make fabric-ca-client
第三步:安裝編譯好的可執行文件
cd $GOPATH/src/github.com/hyperledger/fabric-ca/bin
cp $GOPATH/src/github.com/hyperledger/fabric-ca/bin/* /usr/local/bin
chmod -R 775 /usr/local/bin/fabric-ca-server
chmod -R 775 /usr/local/bin/fabric-ca-client
第四步驟:檢查
fabric-ca-server version
fabric-ca-server version
顯示版本信息爲安裝正確。
2.fabric-ca-server的初始化
第一步:建立文件夾
mkdir -p /opt/hyperledger/fabric-ca-server
cd $GOPATH/src/github.com/hyperledger/fabric-ca
第二步:服務器初始化
fabric-ca-server服務器初始化的命令以下:
fabric-ca-server init -b admin:adminpw
-b 參數後面的是fabric-ca-server服務器管理帳號的用戶名和密碼
啓動fabric-ca-server:
fabric-ca-server start -H /opt/hyperledger/fabric-ca --boot admin:adminpw
Fabric CA (version 1.3 or later)在Fabric-ca-sever初始化的目錄下會生成IssuerPublicKey和IssuerRevocationPublicKey,會在下一步使用。
cd $GOPATH/src/github.com/hyperledger/fabric-ca
idemixgen ca-keygen
會在fabric-ca下生成msp目錄等
生成ca和msp目錄後 ,能夠將目錄中指定的默認簽名者添加到配置
命令例如:idemixgen signerconfig -u OrgUnit1 --admin -e "johndoe" -r 1234
(簽名者是組織單元「OrgUnit1」的成員,註冊標識爲「johndoe」,撤銷句柄爲「1234」,這是一個管理員)
$ idemixgen signerconfig -h
usage: idemixgen signerconfig [<flags>]
Generate a default signer for this Idemix MSP
Flags:
-h, --help Show context-sensitive help (also try --help-long and --help-man).
-u, --org-unit=ORG-UNIT The Organizational Unit of the default signer
-a, --admin Make the default signer admin
-e, --enrollment-id=ENROLLMENT-ID
The enrollment id of the default signer
-r, --revocation-handle=REVOCATION-HANDLE
The handle used to revoke this signer
容許每一個密鑰級的背書策略覆蓋默認的鏈碼級背書策略。
在Fabric1.3版本以前常見的背書策略是:
實例化或者升級chaincode代碼時設置的,例如:
peer chaincode instantiate -C <channelid> -n mycc -P "AND('Org1.peer', 'Org2.peer')"
peer chaincode instantiate -o orderer.qklszzn.com:7050 -C roberttestchannel -n r_test_cc6 -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "OR ('Org1MSP.member','Org2MSP.member')"
若是未指定,默認背書策略:
「OR('Org1.member','Org2.member')」。意思是組織1或組織2的任何成員
在Fabric1.3版本中 shim API 提供了設置和獲取背書策略的方法
SetStateValidationParameter(key string, ep []byte) error
GetStateValidationParameter(key string) ([]byte, error)
對於私有數據有以下方法:
SetPrivateDataValidationParameter(collection, key string, ep []byte) error
GetPrivateDataValidationParameter(collection, key string) ([]byte, error)
爲了幫助設置背書策略並將其編組爲驗證參數字節數組,shim提供了便利功能,容許智能合約開發人員根據組織的MSP標識符處理背書策略:
type KeyEndorsementPolicy interface {
// Policy returns the endorsement policy as bytes
Policy() ([]byte, error)
// AddOrgs adds the specified orgs to the list of orgs that are required
// to endorse
AddOrgs(roleType RoleType, organizations ...string) error
// DelOrgs delete the specified channel orgs from the existing key-level endorsement
// policy for this KVS key. If any org is not present, an error will be returned.
DelOrgs([]string) error
// DelAllOrgs removes any key-level endorsement policy from this KVS key.
DelAllOrgs() error
// ListOrgs returns an array of channel orgs that are required to endorse changes
ListOrgs() ([]string, error)
}
用法:
要爲密鑰設置背書策略,其中須要兩個特定組織來背書密鑰更改,將兩個組織MSPIDs傳遞給AddOrgs(),而後調用Policy()以構造背書策略字節數組,傳遞給SetStateValidationParameter()。
客戶端如今能夠從智能合約查詢中瀏覽結果集,從而能夠支持具備高性能的大型結果集。
分頁是經過指定pagesize(單頁數據條數)和bookmark(查詢起始點),代碼以下:
func (t *SimpleChaincode) queryMarblesWithPagination(stub shim.ChaincodeStubInterface, args []string) pb.Response {
// 0
// "queryString"
if len(args) < 3 {
return shim.Error("Incorrect number of arguments. Expecting 3")
}
queryString := args[0]
//return type of ParseInt is int64
pageSize, err := strconv.ParseInt(args[1], 10, 32)
if err != nil {
return shim.Error(err.Error())
}
bookmark := args[2]
queryResults, err := getQueryResultForQueryStringWithPagination(stub, queryString, int32(pageSize), bookmark)
if err != nil {
return shim.Error(err.Error())
}
return shim.Success(queryResults)
}
做爲對用Go和node編寫的智能合約的當前Fabric支持的補充。如今支持Java,1.3版本將明確可用java進行智能合約的編寫。
基於peer通道的事件服務自己並非新概念(它首次出如今v1.1中),可是v1.3版本標誌着舊事件中心的結束。在升級到v1.3以前,使用舊事件中心的應用程序必須切換到新的基於peer通道的事件服務。
在Fabric1.1和1.2的版本中 core.yaml中有EventHub相關配置,以下
# EventHub related configuration
events:
# The address that the Event service will be enabled on the peer
address: 0.0.0.0:7053
# total number of events that could be buffered without blocking send
buffersize: 100
# timeout duration for producer to send an event.
# if < 0, if buffer full, unblocks immediately and not send
# if 0, if buffer full, will block and guarantee the event will be sent out
# if > 0, if buffer full, blocks till timeout
timeout: 10ms
# timewindow is the acceptable difference between the peer's current
# time and the client's time as specified in a registration event
timewindow: 15m
# Keepalive settings for peer server and clients
keepalive:
# MinInterval is the minimum permitted time in seconds which clients
# can send keepalive pings. If clients send pings more frequently,
# the events server will disconnect them
minInterval: 60s
在1.3的版本,卻沒有了EventHub相關配置。
可是並不影響使用,依然能夠經過
private static EventHub eventHub;
private static PeerEvents.Event goodEventBlock;
eventHub = new EventHub("test", "grpc://lh:99", null, null);
goodEventBlock = PeerEvents.Event.newBuilder().setBlock(blockBuilder).build();
BlockEvent be = new BlockEvent(eventHub, goodEventBlock);
或
channel.registerBlockListener(blockEvent -> {
log.debug("========================Event事件監聽========================");
try {
org.getBlockListener().received(execBlockInfo(blockEvent));
} catch (Exception e) {
e.printStackTrace();
org.getBlockListener().received(getFailFromString(e.getMessage()));
}
log.debug("========================Event事件監聽結束========================");
});
第二部分:Fabric1.3環境搭建
systemctl start sshd service
隨系統一塊兒啓動SSH服務
systemctl enable sshd.service
wget https://storage.googleapis.com/golang/go1.10.linux-amd64.tar.gz
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
export GOPATH=/opt/gopath
wget"https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb" --no-check-certificate
或者
curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py" python get-pip.py
docker pull hyperledger/fabric-baseimage:latest
docker pull hyperledger/fabric-baseos:latest
docker pull hyperledger/fabric-ccenv:latest
安裝java智能合約還須要導入兩個鏡像:
docker pull docker.io/hyperledger/fabric-javaenv:amd64-1.3.0
docker pull docker.io/hyperledger/fabric-tools: latest
docker 鏡像導入導出命令參考
docker save -o nginx.tar nginx:latest
docker load -i nginx.tar
mkdir -p $GOPATH/src/github.com/hyperledger
cd $GOPATH/src/github.com/hyperledger
git clone https://github.com/hyperledger/fabric
查看版本:
cd fabric/
git branch -a (切換如:git checkout release-1.2)
go get github.com/golang/protobuf/protoc-gen-go
mkdir -p $GOPATH/src/github.com/hyperledger/fabric/build/docker/gotools/bin
cp $GOPATH/bin/protoc-gen-go $GOPATH/src/github.com/hyperledger/fabric/build/docker/gotools/bin
注意:go get 以後編譯好的文件會存放到環境變量$GOBIN對應的目錄中,若是沒有設置$GOBIN的值,系統默認將生成的文體存放到$GOPATH/bin下面.
進入到Fabirc源碼所在的文件夾,執行如下命令能夠一次完成Fabric5個主要模塊的編譯過程,具體的命令以下所示:
cd $GOPATH/src/github.com/hyperledger/fabric
make release
make docker(可能報錯,可是不影響)
對於Macos系統,在編譯以前須要進行如下設置:
上述命令執行完成以後,會自動將將編譯好的二進制文件存放在如下路徑中:
$GOPATH/src/github.com/hyperledger/fabric/release/linux-amd64/bin
$GOPATH/src/github.com/hyperledger/fabric/release/darwin-amd64/bin
編譯完成以後,這些模塊已經已經能夠被運行了,可是目前只能在編譯文件所在的文件夾中運行這些模塊,這樣是很是不方便的。爲了更加方便的使用這些模塊,能夠經過下面的命令將這些模塊的可執行文件複製到系統目錄中,這樣在系統中的任何路徑下面都運行這些可執行這些模塊。
Ubuntu和Centos將Fabric模塊編譯後的文件複製到系統文件夾中的方法以下:
cp $GOPATH/src/github.com/hyperledger/fabric/release/linux-amd64/bin/* /usr/local/bin
Macos上面將Fabric模塊編譯後的文件複製到系統文件夾中的方法以下:
cp $GOPATH/src/github.com/hyperledger/fabric/release/darwin-amd64/bin/* /usr/local/bin
複製成功以後經過如下命令修改文件的執行權限,不然沒法執行。
sudo chmod -R 775 /usr/local/bin/configtxgen
sudo chmod -R 775 /usr/local/bin/configtxlator
sudo chmod -R 775 /usr/local/bin/cryptogen
sudo chmod -R 775 /usr/local/bin/peer
sudo chmod -R 775 /usr/local/bin/orderer
經過上面這些命令以後,能夠在系統的任何路徑下面運行這些模塊了。下面經過一組命令來進檢查安裝過程是否成功。
採用 version 命令行選項

快速啓動Fabric一個Fabric應用
生成Fabric須要的證書文件
本例中咱們將配置文件和生成的證書文件放在文件夾/opt/hyperledger/fabricconfig中。
建立存放證書的文件夾的命令以下所示:
mkdir -p /opt/hyperledger/fabricconfig
cryptogen提供了一個命令能夠獲取cryptogen模塊所須要的配置文件的樣式,該命令以下所示:
cryptogen showtemplate
能夠把上述命令生成的內容複製到一個文件中稍加修改便可使用。
本例中咱們所使用的配置文件的內容以下所示:
OrdererOrgs:
- Name: Orderer
Domain: qklszzn.com
Specs:
- Hostname: orderer
PeerOrgs:
- Name: Org1
Domain: org1.qklszzn.com
Template:
Count: 2
Users:
Count: 3
- Name: Org2
Domain: org2.qklszzn.com
Template:
Count: 2
Users:
Count: 2
注意Domain屬性
將上述文件的內容保存到文件夾/opt/hyperledger/fabricconfig中,配置文件命名爲:crypto-config.yaml。保存以後執行以下命令:
cd /opt/hyperledger/fabricconfig
cryptogen generate --config=crypto-config.yaml --output ./crypto-config
該命令執行完成以後咱們會發如今文件夾/opt/hyperledger/fabricconfig中會新增長一個文件夾crypto-config,裏面存放有本例的相關配置文件,能夠經過tree命令查看生成證書文件的內容。
執行 : yum install tree
執行命令 tree -L 5 顯示以下:
├── crypto-config
│ ├── ordererOrganizations
│ │ └── qklszzn.com
│ │ ├── ca
│ │ ├── msp
│ │ ├── orderers
│ │ ├── tlsca
│ │ └── users
│ └── peerOrganizations
│ ├── org1.qklszzn.com
│ │ ├── ca
│ │ ├── msp
│ │ ├── peers
│ │ ├── tlsca
│ │ └── users
│ ├── org2.qklszzn.com
│ │ ├── ca
│ │ ├── msp
│ │ ├── peers
│ │ ├── tlsca
│ │ └── users
經過上述步驟全部的證書文件都已經生成完畢,如今須要將測試域名映射到本機的IP地址上面,不然後面的操做可能會出現錯誤。
執行如下命令以便提取相關的域名,
cd /opt/hyperledger/fabricconfig
tree -L 5
在上述命令顯示的內容中提取出後綴爲 qklszzn.com域名。本例中提取信息以下:
orderer.qklszzn.com
peer0.org1.qklszzn.com
peer1.org1.qklszzn.com
peer3.org1.qklszzn.com
peer0.org2.qklszzn.com
peer1.org2.qklszzn.com
打開端映射文件
vi /etc/hosts
在打開的文件中設置以下內容
192.168.43.105 orderer.qklszzn.com
192.168.43.105 peer0.org1.qklszzn.com
192.168.43.105 peer1.org1.qklszzn.com
192.168.43.105 peer3.org1.qklszzn.com
192.168.43.105 peer0.org2.qklszzn.com
192.168.43.105 peer1.org2.qklszzn.com
輸入以上內容以後保存/etc/hosts文件,而後用ping命令測試如下配置是否正確。
注意:192.168.43.105爲本機的IP地址
6.1系統創始塊的生成
Fabric是基於區塊鏈的分佈式帳本,每一個帳本都擁有本身的區塊鏈,帳本的區塊鏈中會存儲帳本的交易,帳本區塊鏈中的第一個區塊是個例外,該區塊不存在交易數據而是存儲配置信息,一般將帳本的第一個區塊成爲創始塊。綜上所述,Fabric中帳本的第一個區塊是須要手動生成的。configtxgen模塊是專門負責生成系統的創始塊和Channel的創始塊。configtxgen模塊也須要一個配置文件來定義相關的屬性。
在Fabric源碼中提供的configtxgen模塊所須要的配置文件的例子。該文件的路徑是$GOPATH/src/github.com/hyperledger/fabric/sampleconfig,在這個目錄下面有一個名爲configtx.yaml的文件,對這個文件進行修便可使用。因爲創始塊文件是提供給Orderer節點使用,所以咱們建立文件一個文件夾來存在Orderer節點相關的文件。文件夾建立以後把樣例配置文件複製到該文件夾中。
建立存放configtxgen模塊相關配置文件的文件夾的命令以下所示:
mkdir -p /opt/hyperledger/order/
cp -r $GOPATH/src/github.com/hyperledger/fabric/sampleconfig/configtx.yaml /opt/hyperledger/order
cd /opt/hyperledger/order
對configtx.yaml進行修改,修改後的內容以下所示:

配置文件修改完成以後執行以下面命令生成創始塊文件。
cd /opt/hyperledger/order
configtxgen -profile TestTwoOrgsOrdererGenesis -outputBlock ./orderer.genesis.block
上述命令執行完成以後會在文件夾/opt/hyperledger/order中生成文件orderer.genesis.block。這是Fabric系統的創始塊文件。
6.2帳本創始塊的生成
建立Channel也是經過configtxgen模塊完成的,建立Channel初始塊的配置文件和建立系統初始塊的配置文件是同樣的,具體在本例中,Channel的創始塊的配置信息已經定義在本節第一部分系統創始塊的生成中生成的配置文件configtx.yaml中。
建立Channel的命令以下:
configtxgen -profile TestTwoOrgsChannel -outputCreateChannelTx ./roberttestchannel.tx -channelID roberttestchannel
上述命令執行完成以後會在目錄生成文件roberttestchannel.tx,該文件用來生成Channel。除此以外還須要生成相關的錨點文件,生成錨點文件須要執行如下命令:
configtxgen -profile TestTwoOrgsChannel -outputAnchorPeersUpdate ./Org1MSPanchors.tx -channelID roberttestchannel -asOrg Org1MSP
configtxgen -profile TestTwoOrgsChannel -outputAnchorPeersUpdate ./Org2MSPanchors.tx -channelID roberttestchannel -asOrg Org2MSP
上面命令執行完成以後會在相應的文件夾下面生成文件Org1MSPanchors.tx和Org2MSPanchors.tx,這些文件在後面會被使用到。
6.3 Orderer節點的啓動
Orderer節點負責交易的打包和區塊的生成。Orderer節點的配置信息一般放在環境變量或者配置文件中,本例中的配置信息統一存放在配置文件中。在Fabric源碼提供了Orderer啓動所用到的配置文件的實例,將示例配置文件複製到Orderer的文件夾下面修改便可使用。
複製配置文件到Orderer文件夾的命令以下所示:
cd /opt/hyperledger/order
cp $GOPATH/src/github.com/hyperledger/fabric/sampleconfig/orderer.yaml /opt/hyperledger/order
在模板配置文件上稍加修改便可知足本例使用,因爲篇幅本例中咱們只列出須要修改的部分。修改後配置文件中發生變化的內容以下:

要注意配置文件中的相關路徑
在配置文件orderer.yaml所在的目錄執行以下命令啓動orderer
orderer start
6.4 Peer節點的啓動
Peer模塊是Fabric的核心節點,全部的交易數據通過Orderer排序打包以後由Peer模塊存儲在區塊鏈中。全部的Chaincode也是有Peer模塊打包而且激活的。Peer模塊的配置信息一樣由環境變量和配置文件組成,本例中咱們採用配置文的方式來配置peer節點的參數。在設定配置文件以前須要建立一個文件夾存放Peer模塊的配置文件和區塊數據。在Fabric源碼中一樣提供了Peer模塊配置文件的示例,將示例配置文件複製到Peer模塊的文件夾下面修改便可使用。
建立存儲Peer模塊的配置文件和區塊數據的文件夾,並複製示例配置文件的命令以下所示:
mkdir -p /opt/hyperledger/peer
cd /opt/hyperledger/peer
cp $GOPATH/src/github.com/hyperledger/fabric/sampleconfig/core.yaml /opt/hyperledger/peer
在模板配置文件上稍加修改便可使用,因爲篇幅本例中咱們只列出須要修改的部分。修改後Peer模塊配置文件中變化的內容以下所示:

6.5 建立通道
如今咱們能夠建立通道,建立通道的過程一共須要三個步驟。
第一步: 建立通道
export set FABRIC_CFG_PATH=/opt/hyperledger/peer
export set CORE_PEER_LOCALMSPID=Org1MSP
export set CORE_PEER_MSPCONFIGPATH=/opt/hyperledger/fabricconfig/crypto-config/peerOrganizations/org1.qklszzn.com/users/Admin@org1.qklszzn.com/msp
cd /opt/hyperledger/order
//Fabric1.1 版本建立通道
peer channel create -t 50 -o orderer.qklszzn.com:7050 -c roberttestchannel -f /opt/hyperledger/order/roberttestchannel.tx
//Fabric1.3 版本建立通道
peer channel create -o orderer.qklszzn.com:7050 -c roberttestchannel -f /opt/hyperledger/order/roberttestchannel.tx
建立通道完成以後,會在執行命令的當前目錄生成名爲roberttestchannel.block的通道創始塊文件
第二步:讓已經運行的Peer模塊加入通道
export set CORE_PEER_LOCALMSPID=Org1MSP
export set CORE_PEER_ADDRESS=peer0.org1.qklszzn.com:7051
export set CORE_PEER_MSPCONFIGPATH=/opt/hyperledger/fabricconfig/crypto-config/peerOrganizations/org1.qklszzn.com/users/Admin@org1.qklszzn.com/msp
peer channel join -b /opt/hyperledger/order/roberttestchannel.block
在上述建立通道的命令中-b後面的參數爲第一步中生成的文件roberttestchannel.block,須要注意這個文件的路徑。
第三步:更新錨節點
export set FABRIC_CFG_PATH=/opt/hyperledger/peer
export set CORE_PEER_LOCALMSPID=Org1MSP
export set CORE_PEER_ADDRESS=peer0.org1.qklszzn.com:7051
export set CORE_PEER_MSPCONFIGPATH=/opt/hyperledger/fabricconfig/crypto-config/peerOrganizations/org1.qklszzn.com/users/Admin@org1.qklszzn.com/msp
peer channel update -o orderer.qklszzn.com:7050 -c roberttestchannel -f /opt/hyperledger/order/Org1MSPanchors.tx
6.6 Chaincode的部署和調用
如今能夠部署一個Chaincode來測試Peer節點和Orderer節點的部署是否正確。這裏採用Fabric源碼自帶的例子來做爲測試Chaincode。
測試用Chaincode的源代碼路徑以下所示:
$GOPATH/src/github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02
Chaincode相關的測試一共有四個步驟。
查看docker 是否啓動,若是沒啓動,要先啓動
問題:Manifest for docker.io/hyperledger/fabric-ccenv:x86_64-1.1.2-snapshot-ff996aa not found
docker tag hyperledger/fabric-ccenv:latest hyperledger/fabric-ccenv:x86_64-1.1.2-snapshot-ff996aa
//Fabric1.1 安裝智能合約
peer chaincode install -n r_test_cc6 -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02
//Fabric1.3官網安裝智能合約,執行報錯;須要下載fabric-samples,而後把目錄fabric-samples/chaincode/chaincode_example02拷貝到目錄/opt/gopath/src/github.com/chaincode/下
第一步:安裝智能合約
Golang
peer chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go/
Node.js
# this installs the Node.js chaincode
# make note of the -l flag; we use this to specify the language
peer chaincode install -n mycc -v 1.0 -l node -p /opt/gopath/src/github.com/chaincode/chaincode_example02/node/
Java
peer chaincode install -n mycc -v 1.0 -l java -p /opt/gopath/src/github.com/chaincode/chaincode_example02/java/
也能夠把fabric1.1的智能合約拿來用
peer chaincode install -n r_test_cc6 -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02/
第二步: 實例化chaincode代碼
export set CORE_PEER_LOCALMSPID=Org1MSP
export set CORE_PEER_ADDRESS=peer0.org1.qklszzn.com:7051
export set CORE_PEER_MSPCONFIGPATH=/opt/hyperledger/fabricconfig/crypto-config/peerOrganizations/org1.qklszzn.com/users/Admin@org1.qklszzn.com/msp
peer chaincode instantiate -o orderer.qklszzn.com:7050 -C roberttestchannel -n r_test_cc6 -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "OR ('Org1MSP.member','Org2MSP.member')"
注意:組織Org1MSP的全部成員或者Org2MSP的全部成員任意一個背書,若是是and就是組織Org1MSP的全部成員或者Org2MSP的全部成員都要進行背書
第三步:經過chaincode寫入數據
export set FABRIC_CFG_PATH=/opt/hyperledger/peer
export set CORE_PEER_LOCALMSPID=Org1MSP
export set CORE_PEER_ADDRESS=peer0.org1.qklszzn.com:7051
export set CORE_PEER_MSPCONFIGPATH=/opt/hyperledger/fabricconfig/crypto-config/peerOrganizations/org1.qklszzn.com/users/Admin@org1.qklszzn.com/msp
peer chaincode invoke -o orderer.qklszzn.com:7050 -C roberttestchannel -n r_test_cc6 -c '{"Args":["invoke","a","b","1"]}'
第四步:經過chaincode查詢數據
export set CORE_PEER_LOCALMSPID=Org1MSP
export set CORE_PEER_ADDRESS=peer0.org1.qklszzn.com:7051
export set CORE_PEER_MSPCONFIGPATH=/opt/hyperledger/fabricconfig/crypto-config/peerOrganizations/org1.qklszzn.com/users/Admin@org1.qklszzn.com/msp
peer chaincode query -C roberttestchannel -n r_test_cc6 -c '{"Args":["query","a"]}'
若是上述命令都能正確執行,那麼一個簡單的Fabric系統就已經部署完成了。
