const ethers = require("ethers");
const fs = require("fs-extra");
require("dotenv").config();

async function main() {
// http://127.0.0.1:7545
// console.log(process.env.PRIVATE_KEY);
const provider = new ethers.JsonRpcProvider(process.env.RPC_URL);
const wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider);
// const encryptedJson = fs.readFileSync("./.encryptedKey.json", "utf8");
// let wallet = await ethers.Wallet.fromEncryptedJsonSync(
// encryptedJson,
// process.env.PRIVATE_KEY_PASSWORD
// );
// wallet = await wallet.connect(provider);
const abi = fs.readFileSync(
"./SimpleStorage_sol_SimpleStorage.abi",
"utf8"
);
const binary = fs.readFileSync(
"./SimpleStorage_sol_SimpleStorage.bin",
"utf8"
);
const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
console.log("部署中,请稍等...");
const contract = await contractFactory.deploy();
// await contract.deployTransaction.wait(1);
await contract.deploymentTransaction().wait(1);
console.log(Contract Address:${contract.address});
//Get number
const currentFavoriteNumber = await contract.retrieve();
console.log(Current Favorite NUmber: ${currentFavoriteNumber.toString()});
const transactionResponse = await contract.store("7");
const transactionReceipt = await transactionResponse.wait(1);
const updatedFavoriteNumber = await contract.retrieve();
console.log(Updated favorite number is: ${updatedFavoriteNumber});
}

main()
.then(() => process.exit(0))
.catch((error) => {
console.error(error);
process.exit(1);
});
...

Here's my result:
部署中,请稍等...
Contract Address:undefined
Current Favorite NUmber: 0

but i want to get the contract address。
if use deploymentTransaction()，the return is not the contract address，it will only be Contract Address:undefined

You can get the contract address like so:

const contract = await contractFactory.deploy();
console.log(`Contract address: ${contract.target}`);

or like so:

const transactionReceipt = await contract.deploymentTransaction().wait(1);
console.log(`Contract address: ${transactionReceipt.contractAddress}`);

Preferably the second option.
