如何读取未发出的以太坊合同存储值？

我想阅读'0x9ec5557208CB28A7714A2EA3468BD9D5BB15125'的合同存储空间。我尝试过 -

const Web3 = require('web3')
const rpcURL = "https://bsc-dataseed1.binance.org/"
const web3 = new Web3(rpcURL)

let contractAddress = '0x9EC55d57208cb28a7714A2eA3468bD9d5bB15125'
for (index = 0; index < 10; index++){
 console.log(`[${index}]` + 
   web3.eth.getStorageAt(contractAddress, index,16368474).then(res=>{ 
    console.log(res)
   }) 
   )
}

这陷入错误错误：返回错误：找不到标头。我尝试更改块，但陷入相同的错误。仅当我不通过16368474时，该错误才能解决，但这使用了最新的 block，这不是我想要的。我尝试使用web3.py尝试过。它遇到相同的错误。我在做什么错？是否有其他获取存储的方法？

I want to read the contract storage for '0x9EC55d57208cb28a7714A2eA3468bD9d5bB15125' at block 16368474 on BSC .
I tried -

const Web3 = require('web3')
const rpcURL = "https://bsc-dataseed1.binance.org/"
const web3 = new Web3(rpcURL)

let contractAddress = '0x9EC55d57208cb28a7714A2eA3468bD9d5bB15125'
for (index = 0; index < 10; index++){
 console.log(`[${index}]` + 
   web3.eth.getStorageAt(contractAddress, index,16368474).then(res=>{ 
    console.log(res)
   }) 
   )
}

This runs into an error Error: Returned error: header not found .I tried changing blocks but run into the same error . The error only resolves if I don't pass 16368474 but that uses the latest block and that's not what I want . I tried the same with web3.py . It runs into the same error. What am I doing wrong ? Is there an alternate way of getting storage ?

您的代码是有效的 - 问题是节点提供商不支持查询历史状态。

解决方案：使用支持存档节点的其他提供商，例如 Moralis 。

const Web3 = require("web3");
const web3 = new Web3("https://speedy-nodes-nyc.moralis.io/<your_api_key>/bsc/mainnet/archive");
const contractAddress = '0x9EC55d57208cb28a7714A2eA3468bD9d5bB15125';
web3.eth.getStorageAt(contractAddress, 0, 16368474).then(res => {
    console.log(res);
});

Your code is valid - the issue is that the node provider doesn't support querying historic states.

Solution: Use a different provider that supports archive node, e.g. Moralis.

const Web3 = require("web3");
const web3 = new Web3("https://speedy-nodes-nyc.moralis.io/<your_api_key>/bsc/mainnet/archive");
const contractAddress = '0x9EC55d57208cb28a7714A2eA3468bD9d5bB15125';
web3.eth.getStorageAt(contractAddress, 0, 16368474).then(res => {
    console.log(res);
});
