关于ENS
以太坊域名服务(ENS)类似于DNS。但它通过一种更安全和且去中心化的方式来管理网站域名，而且可以通过它发送ETH和ERC-20代币。
ENS注册表记录所有域和子域，以及所有者的详细信息和指向解析器的链接；而解析器是另一个智能合约，处理从名称到地址或其他类型资源的转换，反之亦然。
ENS的运行类似于互联网的DNS，因为它有一个分级系统，允许域名所有者完全控制任何子域。

获取数据
通过合约获取数据
获取owner和resolver
var namehash = require("eth-ens-namehash");
const web3 = new Web3(window.ethereum)
const ENSRegistryWithFallbackContract = new web3.eth.Contract(
ABI,
ENSRegistryWithFallbackAddress
);
var domainHash = namehash.hash(
'xxx.xyz'//ens域名地址
);
ENSRegistryWithFallbackContract.methods
.owner(domainHash)
.call().then(res => {
})
ENSRegistryWithFallbackContract.methods
.resolver(domainHash)
.call().then(res => {

通过graph获取数据
数据基本都用graph查询
获取注册信息
const name = "xxx.xyz".split('.')[0]//只取域名前缀
const id = Web3.utils.sha3(name)
axios.post(
this.GLOBAL.netdata.api_url,
{
query: `
{
registration(id: "${id}") {
id
registrationDate
domain {
name
}
registrant {
id
}
}
}
`
}
).then((res) => {
});

axios.post(

通过ethers.js调用
ethers.js原生支持ens
const provider = new ethers.providers.JsonRpcProvider('https://rinkeby.infura.io/v3/3dd7eb5d146740f4a47e136531e7795e', {
chainId: 4,
name: 'rinkeby',
ensAddress: ensAddress
})
const resolver = await provider.getResolver('xxx.xyz')
const x = await resolver.getAddress(60)//参数是coinType
// 获取余额
const resolver = await provider.getBalance('xxx.xyz')

获取其他值阅读ethjs文档：https://docs.ethers.io/v5/api/providers/provider/#EnsResolver
库
对于批量获取，可以使用ensjs库
