一、后端API 1.1 获取所有交易对接口

GET: https://api.justswap.io/v2/allpairs

参数: page_size : int, 每个分页大小, 最大值 50 page_num: int, 第几个分页, 从0 开始 返回值格式: {

 "data":

 [{

 "0_TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t": {//key:TRX的id和token的id

 "quote_id": "0", // 0表示TRX的id

 "quote_name": "TRX", // 目前只支持TRX的名称

 "quote_symbol": "TRX", // 目前只支持TRX的简称

 "quote_decimal": "6", // TRX的精度为6

 "base_id": "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t", // token的contract
