Facebook Page Post Scraper UPDATE December 2017: Due to a bug on Facebook's end, using this scraper will only return a very small subset of posts (5-10% of posts) over a limited timeframe. Since Facebook now owns CrowdTangle, the (paid) canonical source of historical Facebook data, Facebook doesn't have an incentive to fix the linked bug. On December 12th, a Facebook engineer commented that they are developing a new endpoint for scraping posts chronologically. I will refactor this script once that happens. Until then, there likely will not be any PRs accepted.
A tool for gathering all the posts and comments of a Facebook Page (or Open Facebook Group) and related metadata, including post message, post links, and counts of each reaction on the post. All this data is exported as a CSV, able to be imported into any data analysis program like Excel. The purpose of the script is to gather Facebook data for semantic analysis, which is greatly helped by the presence of high-quality Reaction data. Here's quick examples of a potential Facebook Reaction data visualization using data from CNN's Facebook page:
Usage Scrape Posts From Public Page The Page data scraper is implemented as a Python 2/3 script in get_fb_posts_fb_page.py; fill in the App ID and App Secret of a Facebook app you control (I strongly recommend creating an app just for this purpose) and the Page ID of the Facebook Page you want to scrape at the beginning of the file. Then run the script by cd into the directory containing the script, then running python get_fb_posts_fb_page.py or python3 get_fb_posts_fb_page.py. Scrape Posts from Open Group To get data from an Open Group, use the get_fb_posts_fb_group.py script with the App ID and App Secret filled in the same way. However, the group_id is a numeric ID. For groups without a custom username, the ID will be in the address bar; for groups with custom usernames, to get the ID, do a View Source on the Group Page, search for the phrase "entity_id", and use the number to the right of that field. For example, the group_id of Hackathon Hackers is 759985267390294.
Scrape Comments From Page/Group Posts To scrape all the user comments from the posts, create a CSV using either of the above scripts, then run the get_fb_comments_from_fb.py script, specifying the Page/Group as the file_id. The output includes the original status_idwhere the comment is located so you can map the comment to the original Post with a JOIN or VLOOKUP, and also a parent_id if the comment is a reply to another comment. Keep in mind that large pages such as CNN have millions of comments, so be careful! (scraping throughput is approximately 87k comments/hour) Privacy This scraper can only scrape public Facebook data which is available to anyone, even those who are not logged into Facebook. No personally-identifiable data is collected in the Page variant; the Group variant does collect the name of the author of the post, but that data is also public to non-logged-in users. Additionally, the script only uses officially-documented Facebook API endpoints without circumventing any rate-limits. Note that this script, and any variant of this script, cannot be used to scrape data from user profiles. (and the Facebook API specifically disallows this use case!) Known Issues • UTF-16 text (CJK) sometimes fails. • GIFs in comments will not appear for an App access_token. (it requires a User access_token for no apparent reason).
