#PicoCTF2014 Backend

1. How to run the backend application

Step 1 : Install Node.js, npm, mongodb.(I assume you know how to do it)

Step 2 : Install node modules:

  cd PicoCTF2014/
  sudo npm install

Step 3 : Run the application

  node app.js

2. In-game queries

(note that xxx.xxx.xxx.xxx refers to host ip.)

Get information :

• Get team info : http://xxx.xxx.xxx.xxx:3000/team?tid=?
• Get problem info : http://xxx.xxx.xxx.xxx:3000/problem?pid=?
• Get achievement info : http://xxx.xxx.xxx.xxx:3000/achievement?aid=?

Update team information :

using POST instead of GET, see client.js for instance.

• Problem solved : http://xxx.xxx.xxx.xxx:3000/problemsolved
• Achievement unlocked : http://xxx.xxx.xxx.xxx:3000/achievementunlocked
• Problem displayed : http://xxx.xxx.xxx.xxx:3000/problemdisplayed
• Achievement displayed : http://xxx.xxx.xxx.xxx:3000/achievementdisplayed

3. Add/Remove teams/problems/achievements:

Team :

• Add team : http://xxx.xxx.xxx.xxx:3000/newteam
• Remove team : http://xxx.xxx.xxx.xxx:3000/removeteam?tid=?
• Team list : http://xxx.xxx.xxx.xxx:3000/teamlist
• Clear team records : http://xxx.xxx.xxx.xxx:3000/clearrecords?tid=?

Problem :

• Add problem : http://xxx.xxx.xxx.xxx:3000/newproblem
• Remove problem : http://xxx.xxx.xxx.xxx:3000/removeproblem?pid=?
• Problem list : http://xxx.xxx.xxx.xxx:3000/problemlist

Achievement :

• Add achievement : http://xxx.xxx.xxx.xxx:3000/newachievement
• Remove achievement : http://xxx.xxx.xxx.xxx:3000/removeachievement?aid=?
• Achievement list : http://xxx.xxx.xxx.xxx:3000/achievementlist

(note that it's NOT a auto-incrementing field for problem id/team id/achievement id, The reason is that I think you might not want the ids to be sequential and somehow use it as a unique username. So you might have to specify the id and dublicate ids are not allowed.)
