从包含promise的函数返回变量

Question

我正在创建一个使用npm中的steamapi的应用程序，我需要从一个函数中获取一个变量，该函数包含一个将HTML页面呈现给客户端的承诺。这是我到目前为止的代码。const SteamAPI = require('steamapi');const steam = new SteamAPI('redacted');function steampicture(steamid) {    steam.getUserSummary(steamid).then(function (data) {        return summary.avatar.large;    })}function steamname(steamid) {    steam.getUserSummary(steamid).then(summary => {        return summary.nickname;    })}var express = require('express'),    app = express();app.use(express.static(__dirname + '/public'));app.engine('html', require('ejs').renderFile);app.get('/', function (req, res) {    var steamid = req.query.steamid;    console.log(steampicture(steamid))    res.render('index.html', {        name: steamname(steamid),        picture: steampicture(steamid),    });});app.listen(80);谢谢，IOnicisere

您应该返回包装在另一个Promise中的变量。您不能确定函数是否成功，所以您也应该处理失败
