在 docker 中测试 chaincode_example02.go 时出错

Question

我只是按照 区块链指南 (https://github.com/yeasy/blockchain_guide) 来测试 docker.

中的 hyperledger 项目 example02

但是当我键入 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'

很奇怪。我用谷歌搜索但没有找到答案。任何人都可以帮助我吗？谢谢。

实际上，当我使用 pbft 模式并键入 docker-compose up 时。我收到以下错误，但我忽略了它。是这个原因吗？

Answer 1

格式已更改。参数 "Function" 已移至 "Args" 数组。所有参数都应该是base64编码的。
旧格式：

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

新格式：

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

已更新：格式再次更改。不再需要 Base64 编码。最新的正确有效载荷（测试于 08.31.2016）Fabric 的版本是：

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