领取奖励流程#

对于领取奖励，流程指引见概述中的领取奖励金流程部分。

1. 设置你的环境#

2. 搜索用户持仓#

以下是一个 Node.js 请求的示例。接口详情看这里。

步骤 1：定义参数#

接下来，定义获取用户持仓的请求参数。

const domain = 'https://www.okx.com';
const exploreBasePath = '/api/v5/defi/explore';
const transactionBasePath = '/api/v5/defi/transaction';
const userBasePath = '/api/v5/defi/user';
const calculatorBasePath = '/api/v5/defi/calculator';
const exploreBaseUrl = domain + exploreBasePath; // Explore API base url
const transactionBaseUrl = domain + transactionBasePath; // Transaction API base url
const userBaseUrl = domain + userBasePath; // User API base url
const calculatorBaseUrl = domain + calculatorBasePath; // Calculator API base url

const getUserAssetBody = {
"address":"0x7f****da",
"investmentId":"15299",
"chainId":"137"
};

步骤 2：定义辅助函数#

定义一个辅助函数，用于与 DeFi API 进行交互。

const getUserAssetData = async () => {
  return fetch(calculatorBaseUrl + '/asset-detail', {
    method: 'POST',
    headers: headersParams,
    body: JSON.stringify(getUserAssetBody),
  })
    .then((res) => res.json())
    .then((res) => {
      return res;
    });
};

步骤 3：获取结果#

async function someFunction() {
    const { data: userAssetData } = await getUserAssetData();
    console.log(userAssetData);
}

someFunction();

发送交易后，你将收到以下响应：

const getProductDetailParam = {
  investmentId: '21010',
  investmentCategory: ''
};

步骤 2：定义辅助函数#

const getProductDetailRequestUrl = (api, queryParams) => {
  const path = api + '?' + new URLSearchParams(queryParams).toString();
  return {
    apiRequestUrl: exploreBaseUrl + path,
    path: exploreBasePath + path,
  };
};
const getProductDetailData = async () => {
  const { apiRequestUrl, path } = getProductDetailRequestUrl(
    '/product/detail',
    getProductDetailParam
  );
  return fetch(apiRequestUrl, {
    method: 'GET',
    headers: headersParams,

    }
}

4. 生成用于领取奖励金交易的调用数据#

以下是一个 Node.js 请求的示例。接口详情看这里。

步骤 1：定义参数#

定义领取奖励金业务需要的参数。

const expectOutputList = [
{
"chainId": "56",
"coinAmount": "10",
"tokenAddress": "0x526a913a7a4518aa2abc3dcd3c46a9c73f40f94a"
}
];
const getTransactionBonusBody = {
address: "0x7f****da",
expectOutputList: expectOutputList,
investmentId: "21670",
extra: "{\"callDataExtJson\":\"\",\"redeemCalldataExtInfo\":[],\"rewardAddress\":\"\"}"
};

步骤 2：定义辅助函数#

定义一个辅助函数，用于与 DeFi API 进行交互。

const getTransactionBonusData = async () => {
return fetch(transactionBaseUrl + '/bonus', {
method: 'POST',
headers: headersParams,
body: JSON.stringify(getTransactionBonusBody),
})
.then((res) => res.json())
.then((res) => {
return res;
});
};

步骤 3：获取结果#

async function someFunction() {
    const { data: transactionBonusData } = await getTransactionBonusData();
    console.log(transactionBonusData);
}

someFunction();

发送交易后，你将收到以下响应：

{
    "code": 0,
    "msg": "",
    "data":
    {
        "dataList":
        [
            {

                "signatureData": "b19f75a8c211c752ff5c82aa130eccee229d16dd05d56874c7a9fd876c5d6d61500dc326ff0aa65b747bca2a2b5cd111e93b53deda73491d8eca97acf8cceb521c"
            }
        ]
    }
}

5. 签名和广播#

签名时可以直接使用第三步获得的 serializedData 作为 Call data ，也可以由用户通过 originalData 自己拼装 Call data 进行签名广播。EVM 类投资品参考签名示例。
