如何使用set 2 checkout身份验证标头？

Question

https：//knowledgecenter.2checkout.com/api-integration/rest_5.0_reference#/introduction/authentication/json-encoded-requestsists

这里是我尝试要求的片段

const axios = require('axios')
const moment = require('moment')
const saltedMd5 = require('salted-md5');

let now = moment().format('YYYY-MM-DD HH:MM:SS')
let vendorCode = '250207358831'

let toHash = vendorCode.length + vendorCode + now.length + now

let salt = '~0CSl)!M@4rZ|zX5QR&s'
const hash = saltedMd5(toHash, salt)

axios.get('https://api.2checkout.com/rest/5.0/subscriptions/?Email=customer%40email.com&AvangateCustomerReference=1234567&ExternalCustomerReference=abcdefg&Page=1&Limit=10&PurchasedBefore=2015-12-29&PurchasedAfter=2015-01-15&ExpireBefore=2016-05-22&ExpireAfter=2015-07-23&Type=regular&Aggregate=false', {
  headers: {
    'X-Avangate-Authentication': `code="${vendorCode}" date="${now}" hash="${hash}"`,
    'Content-Type': 'application/json',
    'Accept': 'application/json'
  }
}).then(res => {
  console.log(res)
}).catch(err => {
  console.log(err)
})

class TwoCheckoutService {
    tco: {
        domain:string;
        apiUrl: string,
        apiUser:string,
        apiPass:string,
        sellerId:string,
        privateKey:string,
        secretKey:string,
        demo:boolean,
    };

    constructor(private userService: UserService) {
        this.tco = {=
            apiUrl: 'https://api.2checkout.com/rest/6.0',
            apiUser: "=",                              
            apiPass: "=",                              
            sellerId: "=",

            demo: true,                                             
            // sandbox: false                                         
        };
    }

    private async _getAuthHeaders(): Promise<{[key:string]: string}> {

        var code = this.tco.sellerId;
        var date = moment().utc().format('YYYY-MM-DD hh:mm:ss');
        var stringToHash = code.toString().length + code + date.toString().length + date;
        var hmac = crypto.createHmac('md5', this.tco.secretKey);
        hmac.update(stringToHash, 'utf8');
        
        var hash  = hmac.digest('hex')
        var authHeader = `code="${code}" date="${date}" hash="${hash}"`

        return {
            'X-Avangate-Authentication': authHeader,
            'Content-Type': 'application/json',
            'Accept': 'application/json'
        };
    }

    async getProducts() {
        var url = this.tco.apiUrl + '/products/';
        var headers = await this._getAuthHeaders();
        console.log(headers);
        var res = await Axios.get(url, {
            headers: headers,
            params: {
                'Limit': 10,
                'Page': 1,
            },
            validateStatus: (status)=>true
        });

        if(res.status === 200) return res.data;
        return {
            error:  true,
            data: res.data,
            url: url,
            headers: headers
        }
    }
}

tolowing正在使用REST API V6（文档：
• Https：//app.swaggerhub.com/apis/2checkout-api/api/api-rest_documentation/6.0-oas3#/subscription/get_subscript_
）

const fetch = require('node-fetch');
const crypto = require('crypto');

const API_URL = 'https://api.2checkout.com/rest/6.0/subscriptions/';
const MERCHANT_CODE = 'TODO: set merchant code';
const SECRET_KEY = 'TODO: replace with secret key from https://secure.2checkout.com/cpanel/webhooks_api.php';
const LIMIT = 100;

function generateAuthHeader() {
    const requestDate = new Date().toISOString().slice(0, 19).replace('T', " "); // UTC Format: YYYY-MM-DD HH:MM:SS
    const stringToHash = `${MERCHANT_CODE.length}${MERCHANT_CODE}${requestDate.length}${requestDate}`;

    const hash = crypto.createHmac('sha256', SECRET_KEY).update(stringToHash).digest('hex');

    return `code="${MERCHANT_CODE}" date="${requestDate}" hash="${hash}" algo="sha256"`;
}

async function fetchSubscriptions(page = 1) {
    try {
        const url = `${API_URL}?Page=${page}&Limit=${LIMIT}&RecurringEnabled=true`;
        console.log(`Fetching Page: ${page}...`);

        const response = await fetch(url, {

        if (!response.ok) {

        }

        const data = await response.json();

        if (data.Items.length === LIMIT) {
