在docker中测试chaincode_example02.go时发生错误

Question

我只是按照区块链指南（https://github.com/yeasy/blockchain_guide）在docker中测试hyperledger项目example02。

但是，当我输入peer chaincode deploy -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'时，出现以下错误。

Error: Non-empty JSON chaincode parameters must contain exactly 1 key: 'Args'

这很奇怪。我GOOGLE了它，但没有找到答案。任何人都可以帮助我？谢谢。

其实，当我使用pbft模式并输入docker-compose up。我收到以下错误，但我忽略了它。这是原因吗？

Answer 1

格式发生了变化。参数“功能”已移至“参数”数组。所有参数应该是base64编码的。
旧格式：

{"function":"init","args":["a", "1000", "b", "2000"]}}

新格式：

{"args":['aW5pdA==', 'YQ==', 'MTAwMA==', 'Yg==', 'MjAwMA==']}

更新：格式再被更改了。 Base64编码不再需要。在最新的（测试2016年8月31日）面料的版本正确有效载荷是：

{“args”:['init', 'a', '100', 'b', '100']}
