We need to crawl in total 10 different sites
Project plan // readme
PHP based server-side application that..
Crawls through specified web content (multiple \'data URLs\', not just a single one.) (Data URL = data source web page)
Data URLs can be looped (for loop for query string), extracted from an array, or crawled from a web page with certain rules to find the right URLs.
Extracts specified data fields from the \'data URLs\', and forms a JSON object of them.
Stores this JSON object into MongoDB using MongoDB PHP Driver.
When executed, is able to send the crawled data from MongoDB in JSON to a remote server via HTTP POST request.
Example of a page to be crawled (1):
[url removed, login to view]
Data URLs are found from this page, before the \'h3.job-header\' element. -> Example Data URL example: [url removed, login to view] Data to crawl from a data URL example: [url removed, login to view]
Example of a page to be crawled (2):
[url removed, login to view]
Data URLs are found from this page as a first link element inside of \'tr.job-item\' table row. -> Example Data URL example: [url removed, login to view] Data to crawl from a data URL example: 1. [url removed, login to view] 2. [url removed, login to view] (Note that some of the data pieces will have to extracted from a text part, so certain amount of regular expressions // other data sorting methods are required here.)
The application should be structured in a way, where core crawling & data processing models are separate from the data source specific crawler parts.
By \'data source specific\', I mean that we\'ll want a separate files for each web resource to be crawled, for example \'Cvmarket\' for [url removed, login to view] specific rules / guides, and \'CVCrawler\' for [url removed, login to view] specific rules. These should extend the core crawling & data modelling parts of the application.
Example:
-> [url removed, login to view] executes multiple individual .php files, which each crawl a single data source.
-> It simultaneously spits progress output (+ possible errors) in console + log file about the process. (example below)
### Storing the results to database.. ###
### Data stored successfully! ###
Example application structure from our other crawler project: [url removed, login to view]
(Here\'s zipped repo to examine the prevous project\'s code for guidance: [url removed, login to view])
1. [url removed, login to view] <- cURL implement functions
2. [url removed, login to view] <- Bundless individual crawler files into one executable, and stores the results into MongoDB
3. [url removed, login to view], [url removed, login to view], [url removed, login to view] + the rest <- individual crawler files for 1 file per 1 data source.
The MongoDB should look like this, when the [url removed, login to view] has been executed a couple times: [url removed, login to view]
