我正在按照http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/上的说明进行操作。

我在 Windows 上使用 Docker Toolbox，我可以成功启动 peer 和 CA。这是我启动 peer 和 CA 时的日志：

[33mvp0_1         |[0m [36m13:18:52.349 [peer] chatWithSomePeers -> DEBU 04c[0m Starting up the first peer of a new network

但是当我使用以下命令启动链代码时

CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=0.0.0.0:7051 ./chaincode_example02

我得到以下错误：

19:30:34.138 [shim] INFO : error with chaincode log level: logger: invalid log level level=

为什么我会收到此错误？

如果您尝试执行这些步骤： https ://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#starting-and-registering-the-chaincode

您需要将 CORE_PEER_ADDRESS=0.0.0.0:7051 更改为 dockercompose_vp0_1 的内部 IP

osboxes@osboxes:~$ sudo docker exec -it dockercompose_vp0_1 ifconfig | grep "inet addr"
      inet addr:172.17.0.3  Bcast:0.0.0.0  Mask:255.255.0.0
      inet addr:127.0.0.1  Mask:255.0.0.0

取eth0的IP地址。它是 172.17.0.3

osboxes@osboxes:/usr/hyperledger/src/first_test$ CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=172.17.0.3:7051 ./chaincode_example02
08:58:16.619 [shim] INFO : error with chaincode log level: logger: invalid log level level=

Docker 默认监听地址 - 192.168.99.100

因此，转到链代码文件夹，使用go build构建链代码

- 将创建一个名为 chaincode_example02 的 exe 文件。

然后运行下面的代码 -

CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=192.168.99.100:7051 ./chaincode_example02
