Lookup any Username on FACEBOOK

In this tutorial we'll be making a small yet effective application rather code snippet to Lookup Any Username on Facebook. The Code Below Uses the Graph API, The Graph API (as defined by Facebook) is the core of Facebook Platform , It allows reading and Writing access to Facebook. It provides a simple view of social graph uniformly representing objects (like people, photos, events, and pages) and the connections between them (friendships, likes, and photo tags).

To make the data handling even more simpler , Facebook returns all responses are JSON objects.

Code

To make it simple and Short I am using Python , but the same can be done in any other language!


main.py

Code:

 #!/bin/python
 import sys # for command line arguments 
 from urllib import urlopen 
 import json # for parsing 
 from StringIO import StringIO 
  
 if len(sys.argv) != 2 : # The Program Name and the Username 
     sys.exit("Usage : "+sys.argv[0]+" Username\n"); 
  
 username = sys.argv[1]; 
  
 data = urlopen("http://graph.facebook.com/"+username).read(); 
  
 io = StringIO(data); 
 user = json.load(io);   
  
 # lets parse it now! :) 
  
 print "ID\t: " , user['id'] ,"\nName\t: " , user['name'] , "\nGender\t: ", user['gender'], "\nlocale\t: " , user['locale']; 
 

Usage :-

Code:

 Usage : main.py Username 
 

Sample Output :-

Code:

 >>python main.py lionaneesh 


 ID    :  1203545662  
 Name    :  Aneesh Dogra  
 Gender    :  male  
 locale    :  en_US 
 

That's all for this tutorial , Stay tuned for more!
