That's so brilliant, thanks so much for sharing your great ideas!

Thanks! Hope it helps.

By the way, one question.
As you know facebook is very familiar with bot recognization.
Is it possible to bypass?

I think the way to bypass the recognization is to make your program's mechanism more randomly, with more humanity.

I haven't run this script in over a year so FB may have made some changes to make it more difficult to scrape. The reason I used selenium is because FB is JavaScipt heavy and I found it too difficult to scrape using other solutions like Scrapy & BeautifulSoup.

I set the script to sleep at certain points to mimic human behavior and it worked fine for me. I agree it would probably be helpful to set the sleep functions to random intervals as long as it's kept to a reasonable range. My only issue with this script was it took too long to scrape the data I wanted because of the delays, but that's the only way I found that worked. I would get blocked if they were too frequent.

I was trying it, but got an error message:

selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: //div[contains(text(), "Vehicles & Bicycles")]

even the div is here

Hmm..does line 43 work for you? You prob need to experiment with the Xpaths to get it to work again.

Hello Kiwibp
Thank you so much for this code, i really need it
i got some lines from you but it doesn't work
i logging to facebook succesfully, but when i can't locate and click "marketplace"
code lines :
marketplace_button = driver.find_element_by_xpath('//div[contains(text(), "Marketplace")]')
marketplace_button.click()

You need to experiment with the xpath. Go into einspect element and find the xpath then paste it in there and it should work.

Doesn't facebook have an api that does this? Thanks for showing this approach though.

If they do please share the documentation! I wasn't aware of it and last time I checked I couldn't find any applicable to the marketplace.

Here is facebook marketplace bot : https://www.youtube.com/watch?v=9KE1sWYfoww&t=2s

@hamzos It says it's private

@carlobianchi89 give me your email i will send you demonstration

hi
Im trying to execute :
$ python3.4m Facebook-Marketplace-Selenium.py
and Im getting:

File "Facebook-Marketplace-Selenium.py", line 158, in <module> app = App() File "Facebook-Marketplace-Selenium.py", line 18, in __init__ self.driver = webdriver.Firefox() File "/usr/lib/python3.4/site-packages/selenium/webdriver/firefox/webdriver.py", line 157, in __init__ self.service.start() File "/usr/lib/python3.4/site-packages/selenium/webdriver/common/service.py", line 76, in start stdin=PIPE) File "/usr/lib64/python3.4/subprocess.py", line 858, in __init__ restore_signals, start_new_session) File "/usr/lib64/python3.4/subprocess.py", line 1456, in _execute_child raise child_exception_type(errno_num, err_msg) NotADirectoryError: [Errno 20] Not a directory

any idea what Im doing wrong ?
Cheers

@kiwikot you probably just need to specify the folder you're going to send the data to based on what I'm guessing from that error message.

def init(self, email= "", password= "",
path='specify/folderpath/here'):

So how do I go if I want to scrape for new postings only (eg 24 hours)? Also, what is the area this script would be using? I want to be able to search nationwide?

Thanks

Hello, from what i could find, these lines of codes arent defined. how is LOCAL_USED_ITEMS supposed to perform?
db = LOCAL_USED_ITEMS

    db.Facebook_items.insert({ 'Url': url,
                     'Images': images,
                     'Title': title,
                     'Description': description,
                     'Date_Time': date_time,
                     'Location': location,
                     'Price': price,          
                    })

thank you for any help:)

@ohliuw this script just manually scrapes when you run the code, you would need to run it manually daily to capture new posts. I haven't used it in a while but I'm sure there's a way you could automate running the script every 24 hours. Also, the area script covers is dependent on the approximate area from which you're signing in. Sounds like you are looking for more commercialized scraping which is beyond the scope of this project

@osrstaurean that method is simply inserting the parameters for each item scraped into the database. The values for the dictionary created for each item are parsed out via the scrape_item_details function of the script.
