node.js - Alexa AWS 错误 : task timed out after 3. 00 秒

Question

我正在尝试编写一个 Alexa 技能，它使用 request.js 和 Cheerio.js 来进行一些网络数据抓取。

当我在本地运行它时，它工作正常，正如预期的那样，但在 AWS lambda 实例上，我不断收到超时错误，因为完成运行所需的时间超过 3 秒。错误日志是这样的:

导致问题的代码片段是:

var URL = 'https://en.wikipedia.org/wiki/' + searchTerm;
                            console.log(URL)
                            request(URL, function(error, response, html){
                                console.log('REQUEST MADE');
                                try {
                                    console.log( 'trying to use cheerio to load page now')
                                    if (html){
                                    var $ = cheerio.load(html);
                                        console.log('PAGE LOADED');
                                        var infobox = $('table.infobox').children('tbody');
                                        infobox.children().each(function(i, element){
                                            var row = $(this);
                                            if(row.children().first().children().first().text() == 'GHS hazard statements') {
                                                var hCodes = row.first().first().text().toString();
                                                var pPhrases = row.first().next().text().toString();
                                                context.succeed(
                                                    generateResponse(
                                                        buildSpeechletResponse(`I found the following ` + hCodes + ` ` + pPhrases, true),
                                                        {}
                                                        ))
                                            }
                                        })

                                } else {
                                    console.log('There was no HTML loaded. Please try again')
                                } 
                                } catch(error){
                                    console.log(error)
                                    console.log('THERE WAS AN ERROR PLEASE TRY AGAIN')
                                }

                            })

我也尝试过使用response.on()，但收到未定义的错误“Cannot do .on”。

以前有人遇到过这样的事情吗？

啊，刚刚根据答案找到了它。我想我应该添加图像。
