# 5. interact with contracts，由于设置了 onlyOwner，最好使用 reade/writeContract 进行交互
#npx hardhat mint --address 0xa9Aa4613FAdA2287935CE5d6D375c28d248b5b50
# 不需要了
#npx hardhat set-base-token-uri --base-url https://bafybeigtcguu2ulkq7wqtqacw42qnbuulktq2gatsggxsuezc2y7zc7r2y.ipfs.nftstorage.link/metadata/
# 6. 设置token-id， 不需要了
#npx hardhat token-uri --token-id 1
#npx hardhat token-uri --token-id 2
# 7. generate metadata，只需要生成一次即可
npx ipfs-car --pack metadata --output metadata.car
npx ipfs-car --pack images --output images.car
# 生成随机图片 https://randomwordgenerator.com/picture.php
# 生成 metadata
node generate_arts/index.js
# 上传到 nft.storage

# 手动执行一次合约的更新 setBaseTokenUri 方法
# 最后，就可以在web界面上让用户mint了
# 以上两步可以通过 Etherscan 进行- 执行
npx hardhat verify <address>时，提示Connect Timeout Error
NomicFoundation/hardhat#2468 https://segmentfault.com/a/1190000018157587
最终确定是网络问题，即使Terminal翻墙也不行。最后使用了 SecureLink 才网络通畅了。
- 执行
npx hardhat verify <address>时，提示Invalid Api Key
原因：是etherscan本身的问题，有bug不稳定，换成polygon的测试网就好了。
