Javascript 遍历列表并进行顺序网络调用

如何使用sdk遍历列表并进行顺序网络调用？ 我正在尝试使用Coinbase的NodeSDK，获取所有帐户的前10个事务

我有一个帐户列表，我遍历它们并调用client.account、client.transactions和client.transactions（分页）。我将结果添加到一个事务数组并返回该数组

我无法让它与异步/等待或请求承诺一起工作。 有什么想法吗

通过使用async/await和Promissions解决了这个问题。等待coinbase方法不会起作用，因为它们不是异步函数（令人惊讶！）

请添加一些您已经尝试过的代码

var rp = require('request-promise');
var coinbase = require('coinbase');
var client = new coinbase.Client({ 'apiKey': 'keyStuff', 'apiSecret': 'secretStuff' });
var accountList = ['acct1','acct2','acct3',];
var transactionList = [];


try {
        let ps = [];
        accountList.forEach(acctId => {
            var account = client.getAccount(accountId, null);
            ps.push(rp(account));
        });
        Promise.all(ps)
            .then(responses => {
                for (var i = 0; i < responses.length; i++) {
                    var result = responses[i];
                    rp(result.account.getTransactions(null))
                        .then(res => {
                            res.pagination = 10;
                            return rp(result.account.getTransactions(null, res.pagination));
                        }).catch(err => console.log(err))
                        .then(txns => {
                            try {
                                if (txns.length > 0) {
                                    txns.forEach(function(txn) {
                                            var transaction = {
                                                "trade_type": "",
                                                "price": ""
                                            };
                                            transaction.trade_type = txn.type;
                                            transaction.price = txn.native_amount.amount;
                                            transactionList.push(transaction);
                                    });
                                }
