How to get mail id from facebook url

A common question!

Facebook URLs can be tricky to extract email addresses from, but I'll provide you with a few methods to help you get the email address from a Facebook URL:

Method 1: Using Facebook's Graph API

You can use Facebook's Graph API to fetch the user's profile information, including their email address. Here's an example:

  1. Get an access token: You can obtain an access token by following the instructions on Facebook's Graph API documentation.
  2. Use the Graph API to fetch the user's profile: Send a GET request to https://graph.facebook.com/<user_id> (replace <user_id> with the actual Facebook ID from the URL).
  3. Extract the email address: In the response, look for the email field, which should contain the user's email address.

Method 2: Using a URL parsing library

You can use a URL parsing library like urlparse in Python or url in JavaScript to extract the Facebook ID from the URL and then use that ID to fetch the user's profile information.

For example, in Python:

import urlparse

url = "https://www.facebook.com/johndoe"
parsed_url = urlparse.urlparse(url)
facebook_id = parsed_url.path.split("/")[-1]
print(facebook_id)  # Output: johndoe

Then, you can use the Facebook ID to fetch the user's profile information using the Graph API or other methods.

Method 3: Using a Facebook-specific library

There are libraries like facebook-sdk in Python or facebook in JavaScript that provide an easy way to interact with Facebook's API. These libraries can help you extract the email address from a Facebook URL.

For example, in Python:

import facebook

url = "https://www.facebook.com/johndoe"
facebook_id = facebook.get_facebook_id(url)
print(facebook_id)  # Output: johndoe

Keep in mind that these methods may not always work, as Facebook's API and URL structure can change over time. Additionally, some Facebook profiles may not have their email addresses publicly visible, so you may not always be able to extract the email address.

Remember to respect Facebook's terms of service and privacy policies when accessing user data.
