【中文标题】通过 JS API 在 OpenSea 上列出 NFT：无法提取 transfer calldata 错误 400

【英文标题】：Listing NFT on OpenSea via JS API: Failed to extract transfer calldata Error 400

【发布时间】：2021-07-19 17:34:31

【问题描述】：

我正在尝试使用OpenSea javascript API 来自动列出要出售的 NFT。我似乎无法弄清楚为什么我不断收到错误Error: API Error 400: ['Failed to extract transfer calldata']。也许我没有正确输入一些数据？我的代码改编自this example。

我在哪里获得数据

ASSET URL

【问题讨论】：

你能解决这个问题吗？我遇到了同样的问题。

【参考方案1】：

你的代币标准是什么？

如果不是 ERC721，则需要在资产对象中将其指定为 schemaName，如下所示：

const fixedPriceSellOrder = await seaport.createSellOrder(
      asset: 
        tokenId: "28370143653034713195993216915191765879963367987017833025925208213530804748289",
        tokenAddress: NFT_CONTRACT_ADDRESS,
        schemaName: "ERC1155"
      ,
      startAmount: 0.1,
      expirationTime: 0,
      accountAddress: OWNER_ADDRESS,
    );

您可以在 Opensea 资产页面的 Details 选项卡中找到 Token Standard：

删除破折号，你很好。 ERC1155 对我来说很好。
