Solidity
如何在 brownie 中訪問 Struct 值
//transaction struct of what a tx should have struct Transaction{ address to; uint value; bool executed; uint numConfirmations; mapping(address => bool) isConfirmed; mapping(address => bool) isRevoked; } //Array of transactions to keep track of each tx Transaction[] public transactions;
一個 Transaction 結構體和一個 Transaction 數組類型。我想訪問數組中的任何 Transaction 值並將其用於測試巧克力蛋糕。我怎樣才能做到這一點?
將感謝您的回复!
你可以這樣做:
# Get accoun account = get_account() # Deploy Contract contract = ContractName.deploy( {"from": account} ) # Retrieve the latest contract contract = ContractName[-1] print(contract.array_name(0))
由於
transactions
數組是公共的,solidity 會自動創建一個getter
函式,該函式與您的數組同名。通過呼叫這個getter,你會得到一個元組。例如:contract.array_name(0)[0]
將列印結構的第一個欄位。
