Go-Ethereum
TypeError: web3.eth.sendTransaction(…).then 不是函式
我試圖在nodejs中使用 ganache 桌面應用程序傳輸一些乙太。它工作正常,但突然發生錯誤。
var s = 1; try{ web3.eth.sendTransaction({ from: '0x627306090abaB3A6e1400e9345bC60c78a8BEf57', to:'0x821aea9a577a9b44299b9c15c88cf3087f3b5544', value: web3.toWei(s.toString(), "ether") }).then(function(receipt) { console.log(receipt); res.json({success: true}); }).catch(function(e){ console.log('error occured'); console.log(e); res.json({success: false }); });
如果.then( **)和.catch()**被刪除,則乙太幣被轉移。
您需要使用回調。請閱讀文件。
var handleReceipt = (error, receipt) => { if (error) console.error(error); else { console.log(receipt); res.json(receipt); } } web3.eth.sendTransaction({ from: '0x627306090abaB3A6e1400e9345bC60c78a8BEf57', to:'0x821aea9a577a9b44299b9c15c88cf3087f3b5544', value: web3.toWei(s.toString(), "ether") }, handleReceipt);
這直接來自文件:
web3.eth.sendTransaction({from: '0x123...', data: '0x432...'}) .once('sending', function(payload){ ... }) .once('sent', function(payload){ ... }) .once('transactionHash', function(hash){ ... }) .once('receipt', function(receipt){ ... }) .on('confirmation', function(confNumber, receipt, latestBlockHash){ ... }) .on('error', function(error){ ... }) .then(function(receipt){ // will be fired once the receipt is mined }); and it does not recognize .once, .on, or.then or.catch
