我正在使用BFT-SMaRt based ordering service
替换超级账本结构中的默认值,它根据BFT-SMaRt订购服务配置tutorial可以正常工作,我可以通过< em>终端命令,例如,甲方可以使用以下命令将10转移到乙方:
peer chaincode invoke -C mychannel -n example02 -c '{"Args":["invoke","a","b","10"]}'
所以现在我假设超级账本结构网络工作正常!
现在,我正在尝试使用基于End2endIT.java
example的fabric-java-sdk(1.2版)与我的网络进行交互,我可以成功使用大多数API,并且可以使用客户端可以成功收到Endorsers
的所有认可回复,但是将信封发送给订购者时,它显示以下错误:
