我的是uniapp项目使用如何实现这个功能？

uni app项目目前还不支持solana链。
如果是网页H5的项目，可以看这里：[GitHub - TP-Lab/tp-js-sdk: TokenPocket JS API for Dapp of ETH, IOST, TRON, COSMOS, SOLANA, EOS etc. (mobile only)](https://github.com/TP-Lab/tp-js-sdk)

能帮我看下问题嘛？
代码：
```
const fromAddress = new web3.PublicKey(from)
const toAddress = new web3.PublicKey(to)
const usdcMintAddress = new web3.PublicKey('Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB')
// console.log(splToken)
/*
console.log("1sendAndConfirmTransaction")
await web3.sendAndConfirmTransaction(connection, transaction, [payer]);
console.log("2sendAndConfirmTransaction")
// Alternatively, manually construct the transaction
manualTransaction.add(
web3.SystemProgram.transfer({
fromPubkey: payer.publicKey,
toPubkey: toAccount.publicKey,
lamports: 1000,
}),
);
let transactionBuffer = manualTransaction.serializeMessage();
let signature = nacl.sign.detached(transactionBuffer, payer.secretKey);
manualTransaction.addSignature(payer.publicKey, signature);
let isVerifiedSignature = manualTransaction.verifySignatures();
console.log(`The signatures were verified: ${isVerifiedSignature}`);
// The signatures were verified: true
let rawTransaction = manualTransaction.serialize();
await web3.sendAndConfirmRawTransaction(connection, rawTransaction); */
// window.solana && window.solana.connect().then(res => {
// console.log(window.solana.publicKey.toBase58())
// });
// api.devnet.solana.com
let connection = new web3.Connection(web3.clusterApiUrl("devnet"), "confirmed");
// const tokenAccounts = await connection.getTokenAccountsByOwner(
// new web3.PublicKey('8YLKoCu7NwqHNS8GzuvA2ibsvLrsg22YMfMDafxh1B15'), {
// programId: splToken.TOKEN_PROGRAM_ID,
// }
// );
// let airdropSignature = await connection.requestAirdrop(
// new web3.PublicKey(from),
// web3.LAMPORTS_PER_SOL,
// );
let transaction = new web3.Transaction();
transaction.add(
splToken.Token.createTransferInstruction(
splToken.TOKEN_PROGRAM_ID,
usdcMintAddress,
toAddress,
fromAddress,
[],
amount
)
);
// 发送交易
let recentBlockhash = await connection.getLatestBlockhash();
transaction.recentBlockhash = recentBlockhash.blockhash
transaction.feePayer = fromAddress
// const signature = await web3.sendAndConfirmTransaction(connection, transaction);
const signedTransaction = await window.solana.signTransaction(transaction, connection);
console.log(signedTransaction)
// const signature = await connection.sendRawTransaction(signedTransaction.serialize());
// console.log(2)
// // var msg = "签名啦!， To avoid digital dognappers, sign below to authenticate with CryptoCorgis"
// var encodedMessage = new TextEncoder().encode(signature);
// var signedMsg = await window.solana.signMessage(encodedMessage);
```
signedTransaction 结果返回异常:Must be connected in order tocommunicate with TokenPocket wallet.
我检查了tp钱包节点是测试，Solana连接的也是测试

connect 的过程为啥 注释掉了？ 要先连接， 如果还不行 试试 主网
