接口及参数解释

APENFT API 提供用户友好的接口，提高可用性，供用户调用与平台交互。API 服务目前适用于主网和 Shasta 测试网。

使用步骤说明

  1. 生成卖方订单信息 SellOrder 需要使用 postOrder 接口。postOrder 接口输入参数较多，可以通过 hashOrder 接口生成。hashOrder 接口返回参数中，r，s，v 这 3 个参数需要使用 生成本地签名信息 生成。
    买方订单信息 BuyOrder 大部分参数与 SellOrder 相同，部分参数需要修改。修改方法参照 生成 BuyOrder 章节。

  2. 查询合集的所有订单使用 queryOrder 接口

hashOrder

请求

  1. 接口功能：生成 postOrder 接口的入参

  2. 请求方式：POST

  3. 请求地址（以测试网为例）：http://ele-testnet.apenft.io/openapi/v1/hashOrder

function newTronWeb(privateKey) {
    let tronWeb = new TronWeb(fullNode, solidityNode, eventServer, privateKey);
    return tronWeb
}

async function orderSign(orderHash, arg2) {  // orderHash comes from response json of hashOrder
    const tronWeb = newTronWeb(arg2)
    const signature = await tronWeb.trx.sign(orderHash, tronWeb.defaultPrivateKey, true);
    const result = signature.substring(2);
    const r = "0x" + result.substring(0, 64);
    const s = "0x" + result.substring(64, 128);
    const v = parseInt(result.substring(128, 130), 16);// The signature is now comprised of r, s, and v.
    return Promise.resolve({
        r, s, v, signature
    });
}

生成 SellOrder

将 hashOrder 返回报文中的 r, s, v 替换为 orderSign 生成的 r, s, v。再将固定值howToCall:0, 插⼊返回的data中 即可⽣成sell订单。

生成 BuyOrder

生成买单 dataToCall

⼊参为买家 address 及NFT资产 tokenID，调⽤ encodeBuyDatatocall ⽅法，⽣成买单 dataToCall。

function encodeBuyDatatocall(buyerAddressStr, tokenId) {
    const from = '0000000000000000000000000000000000000000000000000000000000000000';
    const to = formatHex32Byte(buyerAddressStr);
    const id = formatNumber(tokenId);
    const dataToCall = '0x23b872dd' + from + to + id;
    // console.log("dataToCall:" + dataToCall);
    return dataToCall;
}

function formatHex32Byte(hexStr) {
    let str = hexStr.toLowerCase().startsWith("41") ? hexStr.substring(2).toLowerCase() : hexStr.toLowerCase();
    let zero = '';
    for (let i = str.length; i < 64; i++) {
        zero += '0';
    }
    return zero + str;
}

function formatNumber(num) {
    const hexStr = new BigNumber(num).toString(16);
    return formatHex32Byte(hexStr);
}

根据卖单信息生成买单

修改卖单以生成买单：

  • 买单 maker 取值为卖单 taker
  • 买单 taker 取值为卖单 maker
  • 买单 side 取值为 0
  • 买单 feeRecipient 取值为 0 地址
  • 买单 replacementPattern 取值为替换模式的另一个值：
    卖单中 replacementPattern 取值为模式一时，买单中 replacementPattern 取值为模式二，反之亦然。
模式一：0x000000000000000000000000000000000000000000000000000000000000000000000000ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff0000000000000000000000000000000000000000000000000000000000000000

模式二：0x00000000ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
