智能合約部署問題與解決方案

智能合約部署問題與解決方案

部署好智能合約以後不管輸入什麼參數，返回的都是零值

可以參考以下鏈接：

• https://ethereum.stackexchange.com/questions/75962/call-smart-contract-function-in-geth
• https://ethereum.stackexchange.com/questions/67794/how-to-setup-constantinople-fork-for-private-ethereum-chain
• https://ethereum.stackexchange.com/questions/78616/it-possible-to-hard-fork-a-private-network-without-resyncing-chain-from-scratch
  需要設置分叉，即在gensis.json文件中的config中補充：

    "byzantiumBlock": 0,
    "constantinopleBlock": 0,
    "petersburgBlock": 0,
    "istanbulBlock": 0,
    "ethash": {}

這邊貼出我的完整的創世區塊設置
