This site requires javascript enabled in your browser

In case of simulating a login with JMeter it might be the case when some dynamic token is being generated with JavaScript so you need to extract it from the 1st response source code and add as a parameter to 2nd request so your test should look like: GET request to login page Extract any dynamic parameters (Regular Expression Extractor is mostly used for this) POST request to login page (pass dynamic parameter(s) extracted in previous step along with the credentials) I finally used better free host provider which allows me to download files from server and send request from android client.

After getting a response from my host support team, I found that the problem is from Server Side . I have used the free hosting.

Support Team said to me that their free hosts are only for creating websites and not downloading files from them.

I think this is for be Scraping disabled or maybe not having SSL .

Scraping websites with Javascript enabled?

I wrote a small tutorial on this subject, this might help:

Basically what you do is you have the selenium library pretend that it is a firefox browser, the browser will wait until all javascript has loaded before it continues passing you the html string. Once you have this string, you can then parse it with beautifulsoup.

I’ve had exactly the same problem. It is not simple at all, but I finally found a great solution, using PyQt4.QtWebKit .

You will find the explanations on this webpage : http://blog.motane.lu/2009/07/07/downloading-a-pages-content-with-python-and-webkit/

I’ve tested it, I currently use it, and that’s great !

Its great advantage is that it can run on a server, only using X, without a graphic environment.

You should look into using Ghost, a Python library that wraps the PyQt4 + WebKit hack.

This makes g the WebKit client:

import ghost g = ghost.Ghost() 

You can grab a page with g.open(url) and then g.content will evaluate to the document in its current state.

Ghost has other cool features, like injecting JS and some form filling methods, and you can pass the resulting document to BeautifulSoup and so on: soup = bs4.BeautifulSoup(g.content) .

So far, Ghost is the only thing I’ve found that makes this kind of thing easy in Python. The only limitation I’ve come across is that you can’t easily create more than one instance of the client object, ghost.Ghost , but you could work around that.

JMeter: JavaScript seems to be disabled in your browser [duplicate]

From JMeter project main page

JMeter is not a browser. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages . Nor does it render the HTML pages as a browser does (it’s possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever viewed at a time).

Although JMeter cannot execute JavaScript, it is capable of recording associated HTTP Requests.

In case of simulating a login with JMeter it might be the case when some dynamic token is being generated with JavaScript so you need to extract it from the 1st response source code and add as a parameter to 2nd request so your test should look like:

1. GET request to login page
   • Extract any dynamic parameters (Regular Expression Extractor is mostly used for this)
2. POST request to login page (pass dynamic parameter(s) extracted in previous step along with the credentials)

See how to use jmeter for login authentication for detailed step-by-step instructions.

Postman: You need to enable JavaScript to run this app, Yeah this looks like your calling the page rather than the endpoint and so is returning your index.html by the looks of it. I’d look into making sure you have the current URL. I’d look into making sure you have the current URL.
