docker - 实例化Chaincode时Chaincode for Developers教程错误

Question

这是“Chaincode for Developers Cli error terminal 3”的后续问题。我正在做Chaincode for Developers教程，在运行peer chaincode instantiate -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc命令时出现以下错误。航站楼3。

命令peer chaincode instantiate -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc的输出:

Error: Error getting (myc) orderer endpoint: Error endorsing GetConfigBlock: rpc error: code = Unknown desc = chaincode error (status: 500, message: "GetConfigBlock" request failed authorization check for channel [myc]: [Failed to get policy manager for channel [myc]])

命令的输出:

peer chaincode install -p chaincodedev/chaincode/sacc -n mycc -v 0

我不得不注释掉
command: /bin/bash -c './script.sh
在文件“docker-compose-simple.yaml”中运行命令
docker exec -it cli bash。

谁能告诉我如何解决这个问题？

好吧，我可以看到一些问题，这些问题可能是您所描述的错误的根本原因。首先请注意，在实例化命令期间:

peer chaincode instantiate -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc

您并不是要指向订购服务，因为实例化是一项背书交易，最终必须将其提交给订购服务，因此应该是这样的:

peer chaincode instantiate -o ordererEndpoint:7050 -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc

请注意，您收到的错误会提示您，因为它指出无法获取配置块:

Error: Error getting (myc) orderer endpoint: Error endorsing GetConfigBlock: rpc error: code = Unknown desc = chaincode error (status: 500, message: "GetConfigBlock" request failed authorization check for channel [myc]: [Failed to get policy manager for channel [myc]])

另外，请确保myc是现有 channel ，并且您已经正确创建了它。您可以简单地执行以下操作:

peer channel list

检索对等已加入的 channel 列表。
