報(bào)這種錯(cuò)誤：一般在生成private key前面添加"0x"即可解決。我就是在私鑰前面添加了"0x"解決了。

在學(xué)習(xí)web3時(shí)，使用助詞生成的私鑰，然后由私鑰導(dǎo)出keystore就報(bào)錯(cuò)：

ERROR
Invalid Private Key, Not a valid string or uint8Array

開(kāi)始報(bào)錯(cuò)以為是自己沒(méi)開(kāi)梯子,但我用之前寫(xiě)的demo是能查詢到eth賬戶余額，于是根據(jù)報(bào)錯(cuò)信息懷疑是生成的privatekey不對(duì)，我照著學(xué)習(xí)的視頻檢查了代碼跟它一樣沒(méi)問(wèn)題呀，然后我在生成的私鑰前面添加了"0x"就可以了。

//獲取錢(qián)包私鑰const privateKey=wallet.getPrivateKey().toString("hex");    
const web3 = new Web3(Web3.givenProvider || 'wss://sepolia.infura.io/ws/v3/018c25a8b5ce4f23810c49f60478471f');const keystore = web3.eth.accounts.encrypt('0x'+privateKey,'111111');

搞定。
