在 Web3 中執行方法時“this._eth.sendTransaction 不是函式”

我正在使用 react-web3 （它基本上給了我一個 web3 對象），我正在努力讓我的契約工作。這是我正在使用的程式碼：

const web3 = window.web3;
   const contract = new web3.eth.contract(ABI.abi).at("0xdbb05ed3b5acb77cbd2366d037fe051703958dac");
   contract.buyTicket.sendTransaction(3000, {
       from: '0x5c1a92217e456a7eB4a051B567FC751A534991a3',
       value: web3.toWei(1, 'ether')
   });

任何的想法？

資訊 我正在使用與 testrpc 的契約並用松露將其部署在那裡

您不需要sendTransaction顯式呼叫該函式，只需像這樣呼叫您的智能合約的函式：

contract.buyTicket(3000, {
       from: '0x5c1a92217e456a7eB4a051B567FC751A534991a3',
       gas: 1000000,
       value: web3.toWei(1, 'ether')
   });

也不要忘記定義氣體限制

編輯：您不需要用 實例化新對象new，web3 應該為您提供智能合約的實例：

const contract = web3.eth.contract(ABI.abi).at("0xdbb05ed3b5acb77cbd2366d037fe051703958dac");
