Use Python and gephi to draw social network diagrams for everyone

1. login to their Renren network, enter the web page http://friend.renren.com/myfriendlistx.do#item_0, get such as the page:

Right-click to view the source code, copy a line from your friends list, and save it as myfriends. dat (save as a line of text ).

2. Run the source code:

import urllib,urllib2,cookielibimport redef MyFriends(filename):    patt2='"id":(\d+),"vip":[\s\S]+?"name":"([\s\S]+?)",\"head":"([\s\S]+?)","groups":\["([\s\S]+?)"\]'  #id,name,head,groups    patt='"id":(\d+),'    f=open(filename,'r')    for eachLine in f:        friendList=re.findall(patt,eachLine)    return friendListdef Login(t,JSESSIONID):    cookie={'t':t,'JSESSIONID':JSESSIONID}    cookies=''.join(x+'='+cookie[x]+';' for x in cookie)    return cookiesdef ShareFriends(cookies,friendID):    opener=urllib2.build_opener(urllib2.HTTPCookieProcessor(\        cookielib.CookieJar()))    urllib2.install_opener(opener)    req = urllib2.Request('http://friend.renren.com/shareFriends?\t=0.8142646627966315&p={"init":true,"uid":true,"uhead":true,\"uname":true,"group":true,"net":true,\"param":{"guest":'+friendID+'}}')    req.add_header('Cookie', cookies)    content = urllib2.urlopen(req).read()    patt='"id":(\d+),"netName":"'    friends=re.findall(patt,content)    return friendsdef AllFriendsLinkCSV(cookies,friendList,filename):    f=open(filename,'w')    f.write('Source,Target\n')    for friendID in friendList:        f.write('xxxx,'+friendID+'\n')  # replace XXXX with your ID    for friendID in friendList:        friends=ShareFriends(cookies,friendID)        for ID in friends:            f.write(friendID+','+ID+'\n')    f.close()    def main():    friendList=MyFriends('myFriends.data2')    t,JSESSIONID='xxxxx','xxxxx'    cookies=Login(t,JSESSIONID)    AllFriendsLinkCSV(cookies,friendList,'FriendsLink.csv')    if __name__=='__main__':    main()

The myfriends function is used to obtain a list of friends.

Mutual friends is used to obtain mutual friends with a friend.

Allfriendslinkcsv saves the friend relationship as a CSV file in the format specified by gephi.

In the main function, after obtaining the T and JSESSIONID in the following way, replace XXXXX In the above Code:

Right-click on the Renren page, review elements, and red overwrites under resource options

3. Replace the T and JSESSIONID values and run the above code to get friendslink.csv. Follow the steps below to import CSV files in gephi:

Back to the overview page, you can see the network diagram:

After a series of operations, you can get your own social graphs ~
