0xorderbuilder 中文文档教程
0xOrderBuilder
用于构建订单以使用 0x 协议的库。
Types
- ZeroExOrderBuilder: main class with the static methods:
- buildQuoteProviderOrder: creating a order to use in Quote Provider relayer strategy. A relayer will be called to get conversion rate and fees.
- buildSignedOrder: signing a order. You can use the order returned in previous method.
- EthNetwork: enum, used to inform the desired Ethereum network.
Installation
npm install 0xorderbuilder --save
Use
导入
import { ZeroExOrderBuilder, EthNetwork } from "0xorderbuilder";
import { BigNumber } from "bignumber.js"; // used as parameter in buildQuoteProviderOrder method
buildQuoteProviderOrder
static buildQuoteProviderOrder(maker: string, makerTokenAddress: string, takerTokenAddress: string, makerTokenAmount: BigNumber,
milisecondsToExpire: number, relayerUrl: string, network: EthNetwork): Promise<Order>;
- maker: yours eth wallet address;
- makerTokenAddress: the token address you wish to sell;
- takerTokenAddress: the token address you wish to buy;
- makerTokenAmount: the amount you wish to sell (in base units, e.g.: 1 ZRX => new BigNumber(1000000000000000000));
- milisecondsToExpire: used to calculate the returned order expiration date;
- relayerUrl: the relayer addres used to get conversion rate and fee;
- network: the desired Ethereum network
- return: a promise that will be return a JSON representing the order.
buildSignedOrder
static buildSignedOrder(order: Order, privateKey: string): SignedOrder;
- order: the unsigned order;
- privateKey: the private key of the maker wallet. Note: this private WILL NOT be transfer to relayer or any other;
- return: the signed order.
示例
import { ZeroExOrderBuilder, EthNetwork } from "0xorderbuilder";
import { BigNumber } from "bignumber.js";
function testZeroExOrderBuilder() {
ZeroExOrderBuilder.buildQuoteProviderOrder("0xf60345bcff9feedb98bbdfc996b33cba00ee2c75", "0x6ff6c0ff1d68b964901f986d4c9fa3ac68346570",

"http://localhost:3000/api/v0", EthNetwork.Kovan).then((order) =>
{
const signedOrder = ZeroExOrderBuilder.buildSignedOrder(order, "0x5edd9d13a5d62821bbda8ac6da7d7ca69a1b540dc99ac9232fefc04d09e28055");
