I need a webcrawler library which is supposed to run in the backend/docker with some JavaScript support. There are many websites which are inserting some JavaScript checks in their page and I want them to pass What it needs to support: 1. I need a way to send standard HTTP requests with an URL and some parameters (POST/GET/PUT, etc). At best, I would like this call _NOT_ to be asynchronous. 2. A way to store cookies from request to another, like a cookie jar; 3. I need to get the raw body of the request - the way server responded to the client; 4. I need also a formatted HTML (tidy/*) of how the document actually looks like. I would like the bidders to start their bidding post with "+++". This is how I can tell if you actually read the post. I will simply ignore/remove the others - there are too many to read and many of them are nothing but automated posts/spam. The language you choose is not important as long as it respects the things above. I would prefer Java or Python, but I can accept others - just let me know about this in your post. Again, this will be running in an linux docker, so be prepared for this. I am a programmer myself and I know this can be done. I did it in the past, meanwhile technologies changed and it may take a while until I am up to date with everything. This is the reason why I need your help. Also, this means I have a fair idea of the effort needed, so don't go wild with your bid here. Deliverables: * full source code; * a small demo in docker on how you will crawl [login to view URL] - 4-5 pages at your choice, no need to interpret the results;

Hi there, The requirements are quite clear and straightforward to implement. I am planning to use python along with nodejs. In a common scenario, session and request handling is managed in python and js code is simply passed to node to be executed via subprocess. A dummy window, document and xmlhttprequest objects are created on node side to collect the xhr calls and generated cookies. Then they're passed back to python to be regenerated inside the already running session. I should note that, as much as that seems straightforward there might be exceptions. Namely, if a target website is using certain approaches like viewport check, fingerprinting, mouse tracking you'll need additional measures to deal with them. As far as I can see immoweb is using incapsula bot mitigation. I have recently worked on a crawler to bypass it. Those measures are not needed for incapsula. I can start right after the award and expect to be done with it in 5 days at most. I am planning to use py3 branch, if you instead prefer py2 just let me know please, thanks.

+++ Hi, I can develop a library for you in PHP which will use a headless browser named PhantomJS behind the scenes to load pages you requested along with all the linked JavaScript and CSS files so you can fetch pages which use JavaScript heavily for generating or loading content dynamically. PhantomJS is a WebKit based browser and it has support for ES5 version of JavaScript so you can think of it as an old version of Google Chrome browser. It also has support for storing cookies locally and for caching already retrieved files. Unfortunately, I don't have practical experience with Docker so I can't use that. I will use Symfony's DomCrawler and CssSelector libraries to clean the fetched HTML files and deliver you a crawler object which is somewhat similar to jQuery library object and can be used to retrieve content out of HTML files. If you're interested and would like to discuss your project with me then feel free to send me a message even when I'm offline. I do my best to reply within a few minutes when online and within a few hours when offline.
