通过opensea-js向开放资产报价。

Question

我使用opensea-js与nodejs一起提供开放测试网络资产。守则如下：

process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';

const Web3 = require('web3')
const opensea = require('opensea-js')

const provider = new Web3.providers.HttpProvider('https://rinkeby.infura.io')

const seaport = new opensea.OpenSeaPort(provider, {
  networkName: opensea.Network.Main
})

const call = async () => {
  const accountAddress = "my_metamask_wallet_address_on_rinkeby_network"
  const tokenId = 12
  const tokenAddress = "0x7dca125b1e805dc88814aed7ccc810f677d3e1db"
  const offer = await seaport.createBuyOrder({
    asset: {
      tokenAddress: tokenAddress,
      tokenId: tokenId,
    },
    accountAddress: accountAddress,
    startAmount: 1
  })
  console.log(offer.expirationTime)
}

call()

但是它抛出一个404没有找到的错误，我做错了什么？响应是{"success": false}。

很少的事情

1. 您不能使用HttpProvider，因为opensea-js库应该能够代表您签署事务。尝试使用HDWalletProvider或与您的助记符或私钥类似的东西，以允许签署购买订单。

const HDWalletProvider = require("@truffle/hdwallet-provider");

const provider = new HDWalletProvider({
    mnemonic: "<your wallet mnemonic>",
    providerOrUrl: "rinkeby infura link",
    addressIndex: 1
});

1. 您需要将OpenSeaPort连接到Rinkeby网络。

const seaport = new opensea.OpenSeaPort(provider, {
  networkName: opensea.Network.Rinkeby
})

最后的代码应该类似于

const Web3 = require('web3')
const opensea = require('opensea-js')
const HDWalletProvider = require("@truffle/hdwallet-provider");

const provider = new HDWalletProvider({
    mnemonic: "<your wallet mnemonic>",
    providerOrUrl: "https://rinkeby.infura.io",
    addressIndex: 0
});

const seaport = new opensea.OpenSeaPort(provider, {
  networkName: opensea.Network.Rinkeby
})

const call = async () => {
  const accountAddress = "my_metamask_wallet_address_on_rinkeby_network"
  const tokenId = 12
  const tokenAddress = "0x7dca125b1e805dc88814aed7ccc810f677d3e1db"
  const offer = await seaport.createBuyOrder({
    asset: {
      tokenAddress: tokenAddress,
      tokenId: tokenId,
    },
    accountAddress: accountAddress,
    startAmount: 1
  })
  console.log(offer.expirationTime)
}

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

同样的事情也发生在我身上。事实证明，我试图找回的资产是在孟买测试网上，而不是在林克比上。
