我正在研究 Hyperledger Fabric v1.4.6 和 node sdk v1.4.8,并尝试使用 Docker Swarm 和 Compose 在多个主机上配置它。我的网络由 2 个频道、3 个 org 和一个 raft Orderer 组成。锚节点已在频道上成功更新。
- 主机 1:channel1 有 peer0org1 和 peer0org2 + CA-org1 和 CA-org2 一个 Cli 和一个 Orderer
- 主机 2:channel2 有 peer0org1 和 peer0org3 + CA-org1 和 CA-org3。
我的背书政策是“ AND ('Org1MSP.peer','Org2MSP.peer') ”通道1,通道2 是“ AND ('Org1MSP.peer','Org3MSP.peer') ”
我能够通过 cli 成功构建网络并调用/查询事务,但是当我尝试通过节点 sdk 调用链代码时,错误就开始了。
尝试使用 invoke.js 调用时出现 Node sdk 错误
- warn: [DiscoveryEndorsementHandler]: _build_endorse_group_member >> G1:1 - endorsement failed - Error: failed
to execute transaction 3b8eb8fe01815c3dd03e1fb840f35a3092974de83694e83a0ec13e548682458d: error sending: txid: 3b8eb8fe01815c3dd03e1fb840f35a3092974de83694e83a0ec13e548682458d(channel1) exists

当我使用单个组织背书策略"AND('Org1MSP.peer')"时,此错误得到解决。
此外,我的网关有发现:{ enabled: true, asLocalhost: true } });

此外,节点 sdk 应用程序在 docker 网络之外运行。
