如何使用eth_getBlockByNumber调用Web3WsPropvider of ethers.js？

Question

我试图用以下代码使用eth_getBlockByNumber的Web3WsProvider of ethers.js调用ethers.js：

const Web3WsProvider = require('web3-providers-ws');
.
.
.

const provider = new Web3WsProvider("wss://api.avax-test.network/ext/bc/C/ws", options);
this.client = new ethers.providers.Web3Provider(provider);



const res = await (this.client as ethers.providers.Web3Provider).send(
      "eth_getBlockByNumber", ["0x0", false]
);

但我犯了个错误

Error: the method eth_getBlockByNumber does not exist/is not available

我可以通过邮递员打这个电话，并得到一个结果。为什么我不能对ethers.js做同样的事情？

Answer 1

我想你可以用这个例子：

const ethers = require("ethers");
(async () => {
  const provider = new ethers.providers.JsonRpcProvider("http://sample-endpoint-name.network.quiknode.pro/token-goes-here/");
  const blockData = await provider.getBlock("0xc5043f");
  console.log(blockData);
})();
