正確使用 NFT Swap SDK v4 的過期時間

創建一個 NFT 交易訂單，其中製造商出售單個 721 NFT，並且接受者（與製造商相同的地址）提出以 eth 的價格購買它。無論我將到期值設置為什麼，在估算 gas 時交易都會失敗。只有當到期設置為永不過期的預設值時，我才能讓它工作——2524604400

這是一個工作範例，最小程度地改編自 nft trader sdk 範例—

export const nftSwapTestExample = async (
 provider: BaseProvider,
 signer: Signer,
 accountAddress: string,
 expiresInSeconds: number,
) => {
 // Scenario: User A wants to sell their CryptoPunk for 420 WETH
 const chainId = await signer.getChainId();
 // Set up the assets we want to swap (CryptoPunk #69 and 420 WETH)
 const CRYPTOPUNK: SwappableAssetV4 = {
   tokenAddress: '0xc3415e01ecd8021e1608fda6c7f7a75af0ed5be0',
   tokenId: '0',
   type: 'ERC721', // 'ERC721' or 'ERC1155'
 };

 const FOUR_HUNDRED_TWENTY_WETH: SwappableAssetV4 = {
   tokenAddress: '0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee', // ETH contract address
   amount: ethers.utils.parseEther('0.0001').toString(),
   type: 'ERC20',
 };

 // [Part 1: Maker (owner of the Punk) creates trade]
 const nftSwapSdk = new NftSwapV4(provider, signer, chainId);
 const walletAddressMaker = accountAddress;

 // Approve NFT to trade (if required)
 const needsApproval = await nftSwapSdk.loadApprovalStatus(CRYPTOPUNK, walletAddressMaker);
 if (!needsApproval.contractApproved && !needsApproval.tokenIdApproved) {
   await nftSwapSdk.approveTokenOrNftByAsset(CRYPTOPUNK, walletAddressMaker);
 }

 const expiry = Math.floor(Date.now() / 1000 + expiresInSeconds);

 // Build order
 const order = nftSwapSdk.buildOrder(
   CRYPTOPUNK, // Maker asset to swap
   FOUR_HUNDRED_TWENTY_WETH, // Taker asset to swap
   walletAddressMaker,
   { expiry },
 );
 // Sign order so order is now fillable
 const signedOrder = await nftSwapSdk.signOrder(order);

 // [Part 2: Taker that wants to buy the punk fills trade]

 // Fill order :)
 const fillTx = await nftSwapSdk.fillSignedOrder(signedOrder);
 const fillTxReceipt = await nftSwapSdk.awaitTransactionHash(fillTx.hash);
 console.log(`🎉 🥳 Order filled. TxHash: ${fillTxReceipt.transactionHash}`);
};

// expires in 1 hour, fails
await nftSwapTestExample(provider, signer, 'address', 60*60);
// expires in 1 day, fails
await nftSwapTestExample(provider, signer, 'address', 60*60*24);

感謝您的報告。我修復了buildOrder函式以正確支持傳遞原始 unix 時間戳以進行到期。有機會請更新到 v0.21！

現在expiry正確地支持對Date像或 unix 時間戳（作為一種number類型）。
