Node.js 通过在Microsoft Bot Framework中循环文件动态创建卡

我一直在试用Microsoftbot.dialog（“showShirts”

function (session) {
    var msg = new builder.Message(session);
    msg.attachmentLayout(builder.AttachmentLayout.carousel)
    msg.attachments([
        new builder.HeroCard(session)
            .title("Classic White T-Shirt")
            .subtitle("100% Soft and Luxurious Cotton")
            .text("Price is $25 and carried in sizes (S, M, L, and XL)")
            .images([builder.CardImage.create(session, 'http://petersapparel.parseapp.com/img/whiteshirt.png')])
            .buttons([
                builder.CardAction.imBack(session, "buy classic white t-shirt", "Buy")
            ]),
        new builder.HeroCard(session)
            .title("Classic Gray T-Shirt")
            .subtitle("100% Soft and Luxurious Cotton")
            .text("Price is $25 and carried in sizes (S, M, L, and XL)")
            .images([builder.CardImage.create(session, 'http://petersapparel.parseapp.com/img/grayshirt.png')])
            .buttons([
                builder.CardAction.imBack(session, "buy classic gray t-shirt", "Buy")
            ])
    ]);
    session.send(msg).endDialog();
}).triggerAction({ matches: /^(show|list)/i }); bot framework in node js, 
i saw this sample code in the documentation

我的问题不是手动键入new builder.HeroCard（）…如何创建一个循环来从json数组填充它

我试过这个

var obj = require("./dummy_json");
msg.attachments([
    obj.shirts.forEach(function(data){
        new builder.HeroCard(session)
            .title(data.title)
            .subtitle(data.subtitle)
            .text(data.text)
            .images([builder.CardImage.create(session, data.image_path)])
            .buttons([
                builder.CardAction.imBack(session, data.title, "Buy")
            ])
    },this)
]);

问题是您正在执行循环，但似乎没有向数组添加任何内容

试着这样做：

var attachments = [];
var obj = require("./dummy_json");

obj.shirts.forEach(function(data) {
    var card = new builder.HeroCard(session)
                    .title(data.title)
                    .subtitle(data.subtitle)
                    .text(data.text)
                    .images([builder.CardImage.create(session, data.image_path)])
                    .buttons([
                        builder.CardAction.imBack(session, data.title, "Buy")
                    ])

     attachments.push(card); 
},this)

msg.attachments(attachments);

将其包装在for/forEach调用中？嘿@EzequielJadib我尝试将“new builder.HeroCard（）…”包装在forEach中，并返回一个空的附件数组。

{“type”：“message”，“attachmentLayout”：“carousel”，“attachments”：[]，“locale”：“en-US”，“localTimestamp”：“2017-07-24T20:26:31.414Z”，“from”：{“id”：“0db08g0j3blgl1jfmc”，“name”：“Bot”}，“recipient”：{“id”：“default user”，“name”：“user”}，“inputHint”：“acceptingput”，“id”：null，“replyToId”：“1kf4ad6jjihlk7k73”}

请添加新代码。您的代码错误，您没有向数组添加任何内容。我将发布答案。
