Hyperledger fabric：无法在 chainecode_example02 中调用链代码？

Question

我有自己的网络并尝试使用 chaincode_example02 链码来测试它，遵循第一个网络示例。当涉及到我的shellscipt中的chaincodeInvoke时，控制台显示

Sending invoke transaction on peer0.bank peer0.caseManager...
--tlsRootCertFiles
 --peerAddresses peer0.bank.snts.com:7051 --tlsRootCertFiles
--tlsRootCertFiles

bank 有 2 个 peer，caseManager 有 3 个。什么会导致这个问题？在第一个网络示例中，两个组织都有 2 个对等体，并且运行良好。有人可以帮忙吗？谢谢。

Answer 1

在您的请求中，您使用了 --tlsRootCertFiles 标志但没有为其指定任何路径？你是在外部设置这个吗？如果没有，请尝试像

这样指定它

--tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt

Answer 2

问题在于获取 TLSINFO 的方式。下面的命令用于我们提到 TLSCert 文件的 utils.sh 文件。您需要根据您的要求修改它。

TLSINFO=$(eval echo "--tlsRootCertFiles $PEER_Org_CA")

Answer 3

您需要修改全局变量，使其通用。

需要改，在文件utils.sh的setOrderererGlobals()方法中：

setGlobals() {
  PEER=
  ORG=


  ### ADD THESES LINES !!! ###
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org$ORG.supplychainnet.ch/peers/peer$PEER.org$ORG.supplychainnet.ch/tls/ca.crt

  CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org$ORG.supplychainnet.ch/users/Admin\@org$ORG.supplychainnet.ch/msp
  ### ADD THESES LINES !!! ###

if [ $ORG -eq 1 ]; then
    CORE_PEER_LOCALMSPID="Org1MSP"

   ### COMMENT THESES LINES !!! ###
    #CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG1_CA
    #CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.supplychainnet.ch/users/Admin\@org1.supplychainnet.ch/msp
   ### COMMENT THESES LINES !!! ###

    if [ $PEER -eq 0 ]; then
      CORE_PEER_ADDRESS=peer0.org1.supplychainnet.ch:7051
    else
      CORE_PEER_ADDRESS=peer1.org1.supplychainnet.ch:8051
    fi
  else
    echo "================== ERROR !!! ORG Unknown =================="
  fi

因此，每个对等点的环境路径将自动更新为数字 $PEER 和 $ORG，而不是检索文件顶部定义的全局 PEERx_ORGy_CA 路径。

在 --tlsRootCertFiles

中为各自的对等方传递 ca.crt 文件路径

试一试，效果很好

docker exec -it cli bash

peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca. example.com-cert.pem -C testchannel -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1 .example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2 .example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["invoke","a", "b","20"]}'
