Initiating a contract. Uncaught Error: You must provide the json interface of the contract when instantiating a contract object

Question

我正在尝试以这种方式启动合同：

function initContract() {
  var contractJSON = $.getJSON("contract.json", function (data) {
    return data;
  });
  return new web3.eth.Contract(contractJSON);
}

我也试过

return new web3.eth.Contract(JSON.parse(contractJSON));

但我认为第二种选择是不必要的。

我有一个很大的contract.json文件，所以我只post其中的一部分：

{
  "contractName": "contract",
  "abi": [
    {
      "anonymous": false,
      "inputs": [
        {
          "indexed": false,
          "internalType": "uint256",
          "name": "id",
          "type": "uint256"
        },
        {
          "indexed": false,
          "internalType": "string",
          "name": "hash",
          "type": "string"
        },
        {
          "indexed": false,
          "internalType": "string",
          "name": "nombre",
          "type": "string"
        },
        {
          "indexed": false,
          "internalType": "string",
          "name": "organizacion",
          "type": "string"
        },
        {
          "indexed": false,
          "internalType": "string",
          "name": "descripcion",
          "type": "string"
        },
        {
          "indexed": false,
          "internalType": "address payable",
          "name": "autor",
          "type": "address"
        },
        {
          "indexed": false,
          "internalType": "uint256",
          "name": "donacionRecibida",
          "type": "uint256"
        },
        {
          "indexed": false,
          "internalType": "uint256",
          "name": "donacionRequerida",
          "type": "uint256"
        }
      ],
      "name": "proyectoDonado",
      "type": "event"
    },


     ...

我不知道 $getJSON 是否需要 json 文件的路径作为参数，或者只是我拥有的名称。我已经看到它在不同的页面上以两种方式编写。无论哪种方式，我都会收到此错误：

Uncaught Error: You must provide the json interface of the contract when instantiating a contract object.
    at Object.ContractMissingABIError (web3.min.js:30304)

希望有人能帮助我！

我有同样的错误解决方法是将接口对象的 abi 属性提供给 web3.eth.Contract 而不是整个对象。例如：

//Get the JSON abi interface definition in whichever way you prefer into an object.
let myInterface = require('../my_contracts/my_contract_interface.json')

//Pass in the abi property of the object
let contract = new this.web3.eth.Contract(myInterface.abi)
