用户API-WebSocket接口
API接口

WebSocketAPI

xt为用户提供了一个简单的而又强大的API,旨在帮助用户快速高效的将xt交易功能整合到自己应用当中。

WebSocket服务地址

xt WebSocket服务连接地址:wss://ws.xt.com/websocket

使用说明

以下API都可以在一个WebSocket 连接进行处理, 通过订阅报文中的action参数来订阅服务器数据。k线、盘口、交易记录数据三类数据服务器首先会返回一次全量数据,之后有新数据时会主动推送。
订阅报文基础格式:

{"dataType":"1_ENTRUST_ADD_EOS_QTUM", "dataSize":1, "action":"ADD"}
dataType: 请求的数据类型, 下面各个章节会详细说明。
dataSize: 请求的数据数量,决定首次全量数据的数量,不传或者为 0 则返回一条数据。
action: 请求的动作类型,ADD:增加数据订阅,DEL:移除数据订阅。 

报文格式比较简单直观,可以先用在线websocket工具简单测试下或者到官网有k线的页面打开开发者模式查看数据后再进行开发。
