Test Order Depth Update

1. 运行trade-server

   • Run : ./trade-server

2. 运行websocket测试程序，接收websocket的推送

   • go run websocket_examples.go

   2019/09/11 16:29:00 recv: {"type":"depth", "payload":{"trading_pair":"abcd/cet","bids":[{"p":"0.005200000000000000","a":"0"}],"asks":null}}
   2019/09/11 16:29:00 recv: {"type":"depth", "payload":{"trading_pair":"abcd/cet","bids":[{"p":"0.005200000000000000","a":"0"}],"asks":null}}

3. 向kafka中输入测试数据

   • kafka-console-producer --broker-list localhost:9092 --topic coinex-dex --property parse.key=true --property key.separator=# < data.txt
   • 该文本文件包含3笔IOC的买单；将这些数据喂给kafka；然后由trade-server进行消费.

4. 测试Rest接口的查询

   • curl -X GET "http://localhost:8000/market/depths?market=abcd%2Fcet&count=10" -H "accept: application/json"
   • Return value : {"sell":[],"buy":[]}
