Events
如何從方法 getPastEvents 中獲取 returnValues?
// 這是我獲取事件資訊的地方。
const myEvent = myContract.getPastEvents('nftCreated', {fromBlock: 10230636})
// 那麼日誌是這樣的:
Promise { <pending>, [Symbol(async_id_symbol)]: 8614, [Symbol(trigger_async_id_symbol)]: 2656, [Symbol(destroyed)]: { destroyed: false } } > [ { address: '0xF8C3b71BfE0bEEA2cF11F51C4B6370d96bD5c98d', blockHash: '0x239f98cab3616bd0e3218eed61a8c871c96d043f5594662364169680752e6b60', blockNumber: 10230636, logIndex: 1, removed: false, transactionHash: '0x885a008946923b39b560d465614e119b668b5117e2acf47abe50d41cd286948f', transactionIndex: 0, id: 'log_185ce0cc', returnValues: Result { '0': 'xxxxxxxxxx', '1': '54366324124', '2': '0x3ac1b7722278da916f3996f09357ebdcb17ad8c54a9424b3826f8326c75a0582', '3': '1645806587', owner: 'xxxxxxxxx', idToken: '54366324124', shaCode: '0x3ac1b7722278da916f3996f09357ebdcb17ad8c54a9424b3826f8326c75a0582', timestamp: '1645806587' }, event: 'nftCreated', signature: 'xxxxxxxxxxxx', raw: { data: '0x000000000000000000000000e3bca80f9dfdc7f72e0e648cdb83c790b20ee45100000000000000000000000000000000000000 00000000000000000ca87c459c3ac1b7722278da916f3996f09357ebdcb17ad8c54a9424b3826f8326c75a0582000000000000000000000000000 00000000000000000000000000000621903fb', topics: [Array] } },
getPastEvents
返回承諾,你必須像下面這樣使用try { const nftCreatedEvents = await myContract.getPastEvents('nftCreated', {fromBlock: 10230636}); console.log(nftCreatedEvents.map(_ev => _ev.returnValues)) }catch(e) { console.log(e) }
