JSDom在Heroku和本地进行不同的分析(JSDom analyze differently on Heroku and in local)

我有些奇怪的东西。我想在网页上获得一些信息（例如这个）。当我从当地进行测试时，没有问题，我得到了我想要的所有细节。

但是当我将脚本推送到heroku时，jsom只提供了一个完全空白的页面，没有任何DOM insisde，所以没有数据。我不明白为什么。

这里是package.json的主要部分：

{ "engines": { "node": "5.8.0", "npm": "3.7.3" }, "dependencies": { "co": "4.6.0", "co-body": "2.0.0", "co-pg": "1.3.1", "jsdom": "9.12.0", "koa": "0.21.0", "koa-bodyparser": "2.0.0", "koa-logger": "1.3.1" }, "devDependencies": { } }

以下是我如何从jsdom创建请求：

jsdom.env({ url: 'https://www.manomano.fr/perceuse/perceuse-visseuse-makita-18-v-li-ion-4-ah-d-13-mm-90249', userAgent : 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.98 Safari/537.36', scripts: [], done: function (err, window) { // err is null, on local or on prod on Heroku /** * Concerning window : * * In production * window.document.querySelector('body').innerHTML === '' * * In local * I got the whole HTML as * I can have navigating with my browser. **/ } });

我尝试了使用或不使用useragent属性。还有“古典”号召：

jsdom.env('https://www.manomano.fr/perceuse/perceuse-visseuse-makita-18-v-li-ion-4-ah-d-13-mm-90249', [same options], [sameCallback]);

有什么想法发生了什么？当然，关于heroku的日志里没有更多的信息......我现在完全停留在这个问题上。我在其他网站做同样的应用程序（真的是一样的，不只是一个克隆/叉），没有问题，没有区别prod heroku和我的本地。

在此先感谢大家和任何想法！

I've something really weird. I want to get some info on a webpage (this one for example). When I test from my local, no problem, I get all the details I want.

But when I push my script to heroku, jsom provides me only a completely blank page without any DOM insisde, so no data. I don't understand why.

Here is the main parts of package.json :

{ "engines": { "node": "5.8.0", "npm": "3.7.3" }, "dependencies": { "co": "4.6.0", "co-body": "2.0.0", "co-pg": "1.3.1", "jsdom": "9.12.0", "koa": "0.21.0", "koa-bodyparser": "2.0.0", "koa-logger": "1.3.1" }, "devDependencies": { } }

And here is how I create the request from jsdom :

jsdom.env({ url: 'https://www.manomano.fr/perceuse/perceuse-visseuse-makita-18-v-li-ion-4-ah-d-13-mm-90249', userAgent : 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.98 Safari/537.36', scripts: [], done: function (err, window) { // err is null, on local or on prod on Heroku /** * Concerning window : * * In production * window.document.querySelector('body').innerHTML === '' * * In local * I got the whole HTML as * I can have navigating with my browser. **/ } });

I have tried with or without the useragent property. And trid too with the "classical" call :

jsdom.env('https://www.manomano.fr/perceuse/perceuse-visseuse-makita-18-v-li-ion-4-ah-d-13-mm-90249', [same options], [sameCallback]);

Any idea on what's happening ? Off course, there is no more info in logs on heroku... I'm completely stuck on this problem for the moment. I do similar thinks in the same app (really the same, not just a clone/fork) with other websites and no problem, no differences between prod heroku and my local.

Thanks in advance to everybody and any idea !
