ERROR 错误：未捕获（在承诺中）：错误：调用恢复异常

Question

使用 angular 和moralis 时，每当我尝试读取任何视图函数时都会出现此错误。下面是返回错误的函数

async contractBalance() {
    let options = {
      contractAddress: CONTRACT_ADDRESS,
      functionName: "investorCount",
      abi: ABI
    }
await Moralis.enableWeb3();
return await Moralis.executeFunction(options);}

下面是我的 abi 和函数的链接

Answer 1

您确定investorCount 的格式正确吗？

它应该看起来像这样。

const ABI = [
 {
    inputs: [],
    name: "message",
    outputs: [
      {
        internalType: "string",
        name: "",
        type: "string",
      },
    ],
    stateMutability: "view",
    type: "function",
  },
  {
    inputs: [
      {
        internalType: "string",
        name: "_newMessage",
        type: "string",
      },
    ],
    name: "setMessage",
    outputs: [],
    stateMutability: "nonpayable",
    type: "function",
  }
];

const readOptions = {
  contractAddress: "0xe...56",
  functionName: "message",
  abi: ABI
};

const message = await Moralis.executeFunction(readOptions);
console.log(message)
// -> "Hello World"

Answer 2

如果您只需要读取数据，则不必启用 Web3。 试试这样的：

const ABI = [...]

const options = {
   address: "xxxx",
   function_name: "investorCount",
   abi: ABI
};

const res = await Moralis.Web3API.native.runContractFunction(options);

如果你想看看 Moralis docs。
