GraphQl的语法

query(vars: String!){ pairDayDatas(where: {pairAddress: vars, date_gt: 1627980769}){ date dailyVolumeToken0 dailyVolumeToken1 dailyVolumeUSD reserveUSD } }

变量: { "vars": "0x58f876857a02d6762e0101bb5c46a8c1ed44dc16" }

添加多个：

query ($vars: String!,$endAt: Int!) {
  pairDayDatas(where: {pairAddress: $vars, date_gt: $endAt}) {
    date
    dailyVolumeToken0
    dailyVolumeToken1
    dailyVolumeUSD
    reserveUSD
  }
}
{ "vars": "0x58f876857a02d6762e0101bb5c46a8c1ed44dc16","endAt":1628043382 }

query ($vars: String!, $endAt: Int!) {
  pairDayDatas(where: {pairAddress: $vars, date_gt: $endAt}, orderBy: date, orderDirection: desc) {
    date
    dailyVolumeToken0
    dailyVolumeToken1
    dailyVolumeUSD
    reserveUSD
  }
}
{ "vars": "0x58f876857a02d6762e0101bb5c46a8c1ed44dc16","endAt":1628467200 }

倒着取第一条：
query ($vars: String!) {
  pairDayDatas(where: {pairAddress: $vars}, orderBy: date, orderDirection: desc,first:1) {
    date
    dailyVolumeToken0
    dailyVolumeToken1
    dailyVolumeUSD
    reserveUSD
  }
}

resetApi 是通过接口来查找数据的   graphQl  是根据类型type

语法：
一、query 查询
①interface 定义一个接口 implements 是实现接口的的实例

如果你要查 implements 里面的值 需要加上... 二、Mutation 修改 三、问题解决办法：
①重命名字段冲突： ②重复片段的使用 ③给你的查询起一个有意义的名称

  swaps(
    orderBy: timestamp
    orderDirection: desc
    where: {timestamp_gt: 1650594240, pool: "0xcbcdf9626bc03e24f779434178a73a0b4bad62ed"}
