你能幫我解析來自 The DAO 的 newProposal 交易的輸入數據嗎？

  • August 1, 2016

每個代表智能合約上的函式呼叫的乙太坊交易都包含一個輸入欄位，其中包含與通過函式介面發送的數據相對應的數據。例如，這個交易（ https://etherscan.io/tx/0x3a7d091970d7931dd5ef4872e59093234e132f861139403d2b69db80ac2d0ecb）是 The DAO 上的一個 newProposal 函式。您可以使用 etherscan 將數據分成 32 個字節的塊。挑選第一個“地址”和第二個“辯論期”相對容易，但我從那裡遇到了麻煩。我假設下一個 32 字節秒是字元串描述的開始，我進一步假設它是 RLP 格式，如下所述：https ://github.com/ethereum/wiki/wiki/RLP ，但是我不確定。

根據 RLP 文件，第三個 32 字節部分應該只有一個字節長，如果它表示 0xca，則表示一個空列表（參見底部的範例）。

所以有兩個問題：（1）如何解析 ehterscan.io 提供的數據的輸入數據（特別是字元串），以及（2）etherscan 是否代表區塊鏈上實際存在的數據？

功能：newProposal(address _recipient, uint256 _amount, string _description, bytes _transactionData, uint256 _debatingPeriod, bool _newCurator)

Q1如何解析 etherscan.io 提供的數據的輸入數據（尤其是字元串）

您將在Ethereum Contract ABI找到對參數進行編碼的資訊。

要解碼參數，請參閱編碼/解碼合約 ABI 數據。

這是 ethabi 的 JavaScript 版本 - https://github.com/jacogr/ethabi-js。

這是一個使用ethabi. 我創建了一個decodeIt包含以下內容的 shell 腳本：

#!/bin/sh

#    function newProposal(
#        address _recipient,
#        uint _amount,
#        string _description,
#        bytes _transactionData,
#        uint _debatingPeriod,
#        bool _newCurator
#    ) onlyTokenholders returns (uint _proposalID);

# Transaction Data Without MethodId

ethabi decode params -t address -t uint256 -t string -t bytes -t uint256 -t bool 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

string Raising the Proposal Deposit to 11 ETH  \n  This Proposal will raise the deposit required to make a Proposal to The DAO from 2 ETH to 11 ETH. \n \n An increase of the Proposal Deposit to **11 ETH** is expected to:\n \n \n \n - decrease the number of poorly thought-out proposals. \n \n - help avoid the confusion and concern that could be caused by hundreds of proposals that cannot be adequately assessed by DAO Token Holders. \n \n - reduce the number of spam proposals and amount of proposal-graffiti on The DAO. \n \n \n   Moreover, the time spent on reviewing proposals by DAO Token Holders should be valued.  Therefore, additional value will accrue to The DAO because of this Proposal from the proposal deposits that stay with The DAO when proposals fail to reach quorum. \n \n While an increase is necessary, **11 ETH is still within reach for small start-ups and individuals** that will want to offer services to The DAO.  \n \n [Join the conversation about this proposal on DAOhub.org](https://forum.daohub.org/t/raising-the-proposal-deposit-to-11-eth/4106)   \n \n ![Graphic: decrease proposals, increase quality](https://ipfs.pics/ipfs/Qmcg2geJ2eCSMEBBSbP8Z56AZgg6mnfTHo56t4SBC74873)   \n \n
