我们正在尝试在我们的应用程序中使用 EIP-3009。第一步我们跟随#3010中的web3部分以下是我们代码的选定部分：

const nonce = web3.utils.randomHex(32);
        const data = {
            types: {
              EIP712Domain: [
                { name: "name", type: "string" },
                { name: "version", type: "string" },
                { name: "chainId", type: "uint256" },
                { name: "verifyingContract", type: "address" },
              ],
              TransferWithAuthorization: [
                { name: "from", type: "address" },
                { name: "to", type: "address" },
                { name: "value", type: "uint256" },
                { name: "validAfter", type: "uint256" },
                { name: "validBefore", type: "uint256" },
                { name: "nonce", type: "bytes32" },
              ],
            },
            domain: {
              name: "Coin Test",
              version: "1",
              chainId: "3",
              verifyingContract: "0xd73ce105814e.......76",
            },const nonce = web3.utils.randomHex(32);
        const data = {
            types: {
              EIP712Domain: [
                { name: "name", type: "string" },
                { name: "version", type: "string" },
                { name: "chainId", type: "uint256" },
                { name: "verifyingContract", type: "address" },
              ],
              TransferWithAuthorization: [
                { name: "from", type: "address" },
                { name: "to", type: "address" },
                { name: "value", type: "uint256" },
                { name: "validAfter", type: "uint256" },
                { name: "validBefore", type: "uint256" },
                { name: "nonce", type: "bytes32" },
              ],
            },
            domain: {
              name: "Things Coin Test",
              version: "1",
              chainId: "3",
              verifyingContract: "0xd73ce105.....Be76",
            },
            primaryType: "transferWithAuthorization",
            message: {
              from: this.state.senderAddress,
              to: this.state.receiverAddress,
              value: 100,
              validAfter: 0,
              validBefore: Math.floor(Date.now() / 1000) + 3600, // Valid for an hour
              nonce: nonce,
            },
          };
          const signedMessage = web3.eth.accounts.sign(data, this.state.privateKey)
            primaryType: "transferWithAuthorization",
            message: {
              from: this.state.senderAddress,
              to: this.state.receiverAddress,
              value: 100,
              validAfter: 0,
              validBefore: Math.floor(Date.now() / 1000) + 3600, // Valid for an hour
              nonce: nonce,
            },
          };
          const signedMessage = web3.eth.accounts.sign(data, this.state.privateKey)

之后，我们使用交易对象并对其进行签名以发送到 Infura。walletAddress 是用以太币支付交易费用的第三人的地址。senderAddress 是发送 erc20 但没有任何以太币来支付费用的人的地址。

const rawTransaction = ({
            from: walletAddress,
            to: contractAddress,
            value: web3.utils.toHex('0'),
            gasprice: web3.utils.toHex('1000'),
            gas: web3.utils.toHex("100000"),
            data: TNGContract.methods.transferWithAuthorization(
                this.state.senderAddress,
                this.state.receiverAddress,
                100,
                0,
                MAX_UINT256,
                nonce,
                signedMessage.v,
                signedMessage.r,
                signedMessage.s, 
              ).encodeABI(),
        });
        console.log('-----------rawTransaction: ' + JSON.stringify(rawTransaction))
        web3.eth.accounts.signTransaction(rawTransaction, privateKey)
            .then((signedTransaction) => {
                console.log('.-----signedTransaction: ' + JSON.stringify(signedTransaction))
                web3.eth.sendSignedTransaction(signedTransaction.rawTransaction).then((receipt)=>{
                    console.log('.-----receipt: ' + JSON.stringify(receipt))
                }).catch(err => {console.log("the error is----- " + err)})
            }).catch((e) => console.log("the error is: " + e));

问题是我们每次发送交易时都会收到“失败并出现错误'EIP3009：无效签名'”。任何帮助都会得到帮助。
