如何追踪MultiversX网络上的交易状态？

Question

有人可以帮助跟踪 MultiversX 网络上价值转移的交易状态吗？

   const testTransaction = new Transaction({
      value: Balance.egld(1),
      data: new TransactionPayload('Test Transfer'),
      receiver: new Address(ownerWallet),
      nonce: sender.nonce,
      gasPrice: new GasPrice(10000000000),
      gasLimit: new GasLimit(1000000)
    });

    await refreshAccount();

    const { sessionId  } = await sendTransactions({
      transactions: testTransaction,
      transactionsDisplayInfo: {
        processingMessage: 'Processing transaction',
        errorMessage: 'An error has occured during Transaction',
        successMessage: 'Transaction successful'
      }
    });

我目前正在使用

sendTransactions

发送我的交易。

根据erdjs文档的说明，可以使用TransactionWatcher。

下面是文档中的简化示例：

await tx1.send(provider);

let watcher = new TransactionWatcher(tx1.hash, provider);
await watcher.awaitStatus(status => status.isExecuted());

我没能使用观察者，所以我每 0.5 秒从 sessionStorage 读取一次数据，直到状态为“成功”

let transactions = JSON.parse(sessionStorage.getItem('persist:dapp-core-transactions'));
    const txData = JSON.parse(sessionStorage.getItem('txData'));
    let txSessionId = sessionStorage.getItem('txSessionId');
    let signedTransactions = JSON.parse(transactions.signedTransactions);
    let currentTransaction = signedTransactions[txSessionId];
    // if (currentTransaction != null) {
    //     let transactionOnNetwork = await watcher.awaitCompleted();
    //     console.log(transactionOnNetwork);
    // }

    // console.log(signedTransactions);
    if (currentTransaction && txSessionId) {
        console.log(currentTransaction);
        if (currentTransaction.status === 'sent') {
            const checkTransaction = setInterval(async () => {
                console.log("Checking transaction status");
                let transactions = JSON.parse(sessionStorage.getItem('persist:dapp-core-transactions'));
                let signedTransactions = JSON.parse(transactions.signedTransactions);
                let currentTransaction = signedTransactions[txSessionId];
                if (currentTransaction.status === 'success' && txData) {
                    clearInterval(checkTransaction);                        
                    await doSomething(currentTransaction);
                    sessionStorage.removeItem('txSessionId');
                }
            }, 500);
        }
    }
