2018-10-11 promise与callback并行执行之Promise.mapSeries对应async.mapSeries

Promise.mapSeries(idarrays, async function(id, callback) {
    querydata.creative_id = '' + id;
    debugasync("sync map debug : ", querydata);
    const rs = await linktestbyid(querydata, queryday);
    debugasync("debug async rs : ", rs);
    return rs;
}).then((rs) => {
    debug("all async rs : ", rs);
    res.send(rs);
});

Promise写法对应的callback写法中的 async.mapSeries

async.mapSeries(idarrays, function(id, callback) {
    querydata.creative_id = '' + id;
    debugasync("sync map debug : ", querydata);
    linktestbyid(querydata, queryday, (rs) => {
        debugasync("debug async rs : ", rs);
        callback(null, rs);
    })
}, (err, rs) => {
    debug("all async rs : ", rs);
    res.send(rs);
});

注： const async = require('async');
var Promise = require('bluebird');
上述两个模块都需要安装哦！

原生Promise对象是没有Promise.mapSeries() 方法的！
