一旦提交了交易,您可能想要提取有关交易结果的信息。SDK 提供了一个 TransactionResponse
类,其中包含帮助方法来公开以下信息:
首先,我们可以从已提交的交易结果中提取这些信息:
// #import { TransactionResponse };
// Call a contract function
const call = await contract.functions.increment_count(15).call();
// Pick off the transaction response
const transactionResponse: TransactionResponse = call.transactionResponse;
// Retrieve the full transaction summary
const transactionSummary = await transactionResponse.getTransactionSummary();
我们还可以使用交易请求的结果提取交易摘要:
// #import { ScriptTransactionRequest, TransactionResponse };
// Instantiate the transaction request using a ScriptTransactionRequest and set
// the script main function arguments
const transactionRequest = new ScriptTransactionRequest({
script: scriptBytecode,
});
transactionRequest.setData(scriptAbi, scriptMainFunctionArguments);
// Fund the transaction
const txCost = await provider.getTransactionCost(transactionRequest);
transactionRequest.maxFee = txCost.maxFee;
transactionRequest.gasLimit = txCost.gasUsed;
await wallet.fund(transactionRequest, txCost);
// Submit the transaction
const response: TransactionResponse = await wallet.sendTransaction(transactionRequest);
// Generate the transaction summary
const transactionSummary = await response.getTransactionSummary();
或者,我们可以从存储的交易 ID 构建交易摘要:
// #import { TransactionResponse };
// Take a transaction ID from a previous transaction
const transactionId = previouslySubmittedTransactionId;
// 0x...
// Retrieve the transaction response from the transaction ID
const transactionResponse = await TransactionResponse.create(transactionId, provider);
// Generate the transaction summary
const transactionSummary = await transactionResponse.getTransactionSummary();
