如何從 Ganache 獲取地址？

  • September 21, 2022

我正在嘗試在 Remix IDE 中實現虛擬智能投票。

我想從Ganache獲取剩餘的 99 個地址來創建一個迭代並讓他們在投票站註冊然後投票。

我如何獲得這些地址？

在此處輸入圖像描述

在 Ganache 上，您可以點擊設置按鈕：

在此處輸入圖像描述

然後在 Accounts & Keys 按鈕上，將 TOTAL ACCOUNTS TO GENERATE 值設置為 100：

在此處輸入圖像描述

然後，您可以使用web3獲取包含所有帳戶的數組：

const Web3 = require("web3");

const web3 = new Web3("http://127.0.0.1:7545");

web3.eth.getAccounts().then((accounts) => {
 console.log("accounts: ", accounts);
});

就我而言，它返回：

讓我知道這是否有幫助。

要在合約中接收一組地址並對其進行處理，您可以嘗試：

// SPDX-License-Identifier: MIT
pragma solidity 0.8.16;

contract Contract {

   address[] public addresses;

   function getAddresses() public view returns(address[] memory) {
       return addresses;
   }

   // Adds one address to the storage addresses array 
   function addAddress(address addr) public {
       addresses.push(addr);
   }

   // Replaces the storage addresses with this new array of addresses
   function addAddresses(address[] calldata _addresses) public {
       addresses = _addresses;
   }

   // Does something on an array of address passed
   function operate(address[] calldata _addresses) public pure {

       for(uint256 i = 0; i < _addresses.length; i++) {
           address addr = _addresses[i];
           // do something with addr
       }

   }

   // Does something on the storage array of addresses
   function operateOnStorageArrayOfAddresses() public view {
       // Makes a copy of the storage address in memory to save gas
       address[] memory addressesCopy = addresses;
       for(uint256 i = 0; i < addressesCopy.length; i++) {
           address addr = addressesCopy[i];
           // do something with addr
       }

   }

}

要通過發送和接收地址與合約進行互動web3，您可以執行以下操作：

const Web3 = require("web3");

const web3 = new Web3("http://127.0.0.1:7545");

web3.eth.getAccounts().then((accounts) => {
 // console.log("accounts: ", accounts);
});

const abi = [
 {
   inputs: [
     {
       internalType: "address",
       name: "addr",
       type: "address",
     },
   ],
   name: "addAddress",
   outputs: [],
   stateMutability: "nonpayable",
   type: "function",
 },
 {
   inputs: [
     {
       internalType: "address[]",
       name: "_addresses",
       type: "address[]",
     },
   ],
   name: "addAddresses",
   outputs: [],
   stateMutability: "nonpayable",
   type: "function",
 },
 {
   inputs: [
     {
       internalType: "uint256",
       name: "",
       type: "uint256",
     },
   ],
   name: "addresses",
   outputs: [
     {
       internalType: "address",
       name: "",
       type: "address",
     },
   ],
   stateMutability: "view",
   type: "function",
 },
 {
   inputs: [],
   name: "getAddresses",
   outputs: [
     {
       internalType: "address[]",
       name: "",
       type: "address[]",
     },
   ],
   stateMutability: "view",
   type: "function",
 },
 {
   inputs: [
     {
       internalType: "address[]",
       name: "_addresses",
       type: "address[]",
     },
   ],
   name: "operate",
   outputs: [],
   stateMutability: "pure",
   type: "function",
 },
 {
   inputs: [],
   name: "operateOnStorageArrayOfAddresses",
   outputs: [],
   stateMutability: "view",
   type: "function",
 },
];

const contractAddress = "0x99Aeb08Ab2fD121138D02F0e5b20D57e0a3a6082";

const contract = new web3.eth.Contract(abi, contractAddress, {
 from: "0xcb21123cD81A08B754735712e099a5Ed5e7748e3",
 gas: 3000000,
});

async function sendAndGetAddresses() {
 const addresses = await web3.eth.getAccounts();

 await contract.methods.addAddresses(addresses).send();

 const retrievedAddressesFromTheContract = await contract.methods
   .getAddresses()
   .call();

 console.log("retrievedAddresses: ", retrievedAddressesFromTheContract);
}

sendAndGetAddresses();
