ethabi
ABI(应用程序二进制接口)基本上是调用合约函数并获取数据的方式。
ABI确定了诸如函数如何被调用以及信息应如何以二进制格式从一个程序组件传递到下一个程序组件的细节...
以太坊智能合约是字节码,位于以太坊区块链上的EVM。在EVM中,一个合约中可能包含多个函数。ABI是必要的,以便您可以指定调用合约中的哪个函数,并且可以确保该函数将以您期望的格式返回数据。 了解更多
该库对函数调用进行编码并解码其输出。
免责声明
该库旨在仅支持由最新版本的Solidity生成的有效ABI。具体来说,我们不打算支持由已知的Solidity错误或未严格遵循规范的库产生的无效ABI。在使用 ethabi
之前,请确保您的ABI已预先处理,以防它不受支持。
安装
cargo install ethabi-cli

ethabi decode log <abi-path> <event-name-or-signature> [-l <topic>]... <data>
ethabi -h | --help
Options:
-h, --help Display this message and exit.
-l, --lenient Allow short representation of input params.
Commands:
encode Encode ABI call.
decode Decode ABI call result.
function Load function from json ABI file.
params Specify types of input params inline.
log Decode event log.
