在docker中測試chaincode_example02.go時發生錯誤

Question

我只是按照區塊鏈指南（https://github.com/yeasy/blockchain_guide）在docker中測試hyperledger項目example02。

但是，當我輸入peer chaincode deploy -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'時，出現以下錯誤。

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

這很奇怪。我GOOGLE了它，但沒有找到答案。任何人都可以幫助我？謝謝。

其實，當我使用pbft模式並輸入docker-compose up。我收到以下錯誤，但我忽略了它。這是原因嗎？

Answer 1

格式發生了變化。參數「功能」已移至「參數」數組。所有參數應該是base64編碼的。
舊格式：

{"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編碼不再需要。在最新的（測試2016年8月31日）面料的版本正確有效載荷是：

{「args」:['init', 'a', '100', 'b', '100']}
