4. Learn to use timed tasks to execute functions
Two . The experimental requirements
Consider the following game scenarios ：
1. Each player has a certain amount of gold coins 、 treasure . There is a market for players to buy and sell treasures . Players can put treasures in the market Listing on the market , Set your own price . Other players pay enough gold , You can buy treasures .
2. Treasures fall into two categories ： One is tools , It decides to hold the player's working ability ; One is accessories , It decides to hold the player's luck .
3. Each player can get one treasure every day through treasure hunt , The value of the treasure is determined by the player's luck . Every player can pass Labor earns gold coins , How much you earn depends on your ability to work .（ A day in the game can be a real day 1 minute 、5 branch
The clock 、10 minute . Self setting .）
4. Each treasure has its own name （ Try not to repeat ）. Each player can wear a limited number of treasures （ For example, a player Only one tool and two accessories can be worn ）. The extra treasure is put in the storage box , It doesn't work , But it can be sold on the market .
5. Treasures listed on the market must be in the storage box and still in the storage box , Until the treasure is sold . Listed treasures can be collected return , And re listed at a new price . When the storage box cannot be filled , The treasure with the lowest luck or working ability will be automatically returned by the system closed .
6. Suppose the game never stops and the ultimate goal of the player is to get the best treasure .
Please build a hypothetical Web game , Available for many people to play online . The interface should be as simple as possible （ Simple text and links are can , Unwanted style）. The background database uses mongodb. The following operations are provided for game players ： Treasure hunt （ Can automatically every Once a day ）、 To make money （ Automatically once a day ）、 Wear treasure 、 Browse the market 、 Buy treasures 、 Listing treasures 、 Take back the treasure .
Submit ： Program + Document requirements ：
1. Documentation is mainly used to explain your database design , That is, what needs to be built collection, Every collection What is the document structure of Well , What indexes need to be built , How applications access databases （ Concrete CRUD command ）;
2. Design for player's operation JSON HTTP Interface to protocol , Custom interface format （request and response Of JSON）; Write test cases and test code for each interface ;
3. Unlimited programming languages and web frame .
