错误处理与重试
// 推荐:为区块链交易实现重试逻辑
async function payJobWithRetry(job, amount, maxRetries = 3) {
let retries = 0;
while (retries < maxRetries) {
try {
await job.pay(amount);
console.log(`成功支付作业 ${job.id}`);
return true;
} catch (error) {
retries++;
console.error(`第 ${retries} 次支付尝试失败:${error.message}`);
if (retries >= maxRetries) {
console.error(`已达到最大重试次数。作业 ${job.id} 的支付失败`);
return false;
}
// 指数退避
await new Promise(resolve => setTimeout(resolve, 1000 * Math.pow(2, retries)));
}
}
