将 AWIS 调用更改为异步函数

Question

我有这个功能：

function AlexaCall(website) {
    var awis = require('awis');

    var client = awis({
        key: keys.alexa.public,
        secret: keys.alexa.secret,
    });

    let responseData = [];

    client({
        Action: 'UrlInfo',
        'UrlInfo.Shared.ResponseGroup': 'Rank',
        'UrlInfo.1.Url': 'lupomontero.com',
        'UrlInfo.2.Url': 'yahoo.com',
        'UrlInfo.3.Url': 'weibo.com',
        'UrlInfo.4.Url': 'github.com',
        'UrlInfo.5.Url': 'monono.org'
    }, (err, data) => {
        // res.length === 5
        // data is an array with a response object for each domain
        data.forEach(function (item) {
            //res.write(item.trafficData.dataUrl);
            responseData.push(item);
        });
        console.log(responseData);
        callback(null, JSON.stringify(responseData));
    });
}

是否可以将其编辑为像这样？

async function PageSpeedCall(website) {
    var pagespeedCall = `https://www.googleapis.com/pagespeedonline/v4/runPagespeed?url=https://${website}&strategy=mobile&key=${keys.pageSpeed}`;
    // second call
    var results = await fetch(pagespeedCall);
    return await results.json();
}

第一个使用AWIS package。文档很清楚，但我需要能够像这样调用函数：

async function callAllSites(websites) {
    var psRes = [];
    var mozRes = [];
    for (let website of websites) {
        psRes.push(await PageSpeedCall(website));
        mozRes.push(await MozCall(website));
    }
    return await {'ps': psRes, 'moz': mozRes};
    // return await [psRes, mozRes];
    // return psRes;
}

callAllSites('google.com','stackoverflow.com')
    .then(results => {
        // console.log(results.ps[3].error)
        // console.log(results.error)
        // console.log(results.ps[0].formattedResults.ruleResults)
        console.log(results);
    })
    .catch(error => console.log(error))
    .then(() => console.log('done'));

我需要传递websites[] 数组，因为这是视图中的内容，用户可以向其中传递多个值。知道如何解决这个问题吗？

这是一个手动承诺的例子。

const awis = require('awis');

async function AlexaCall(website) {

    const client = awis({
        key: keys.alexa.public,
        secret: keys.alexa.secret,
    });

    let responseData = [];

    return new Promise(function (resolve, reject) {
      client({
        Action: 'UrlInfo',
        'UrlInfo.Shared.ResponseGroup': 'Rank',
        'UrlInfo.1.Url': 'lupomontero.com',
        'UrlInfo.2.Url': 'yahoo.com',
        'UrlInfo.3.Url': 'weibo.com',
        'UrlInfo.4.Url': 'github.com',
        'UrlInfo.5.Url': 'monono.org'
      }, (err, data) => {
        if (err) {
          return reject(err);
        }
        // res.length === 5
        // data is an array with a response object for each domain
        data.forEach(function (item) {
            //res.write(item.trafficData.dataUrl);
            responseData.push(item);
        });
        console.log(responseData);
        resolve(JSON.stringify(responseData));
      });
    });
}
