问题描述

Im using express with node.js, and testing certain routes. I'm doing this tute at http://coenraets.org/blog/2012/10/creating-a-rest-api-using-node-js-express-and-mongodb/

我通过ajax调用http://localhost:3000/wines(内容无关紧要).但是我想测试延迟. 2秒后，我可以做些使快递反应的事情吗? (我想模拟ajax加载程序，并且我在localhost上运行，所以我的等待时间几乎为零)

Im calling the http://localhost:3000/wines via ajax (the content doesn't matter). But I want to test latency. Can I do something like make express respond after 2 seconds? (I want to simulate the ajax loader and I'm running on localhost so my latency is pretty much nil)

推荐答案

只需在 setTimeout setTimeout 内调用res.send即可. a>:

Just call res.send inside of a setTimeout:

setTimeout((function() {res.send(items)}), 2000);
