node.js - 评估实时进程

使用Node.js评估实时进程

javascript
const startTime = new Date();
// 模拟一个实时进程的处理任务
function processTask(task) {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      resolve(true);
    }, task.time);
  });
}
// 模拟实时进程的请求
async function makeRequest() {
  const task = { time: 1000 }; // 模拟一个需要1秒钟完成的任务
  const result = await processTask(task);
  const endTime = new Date();
  const responseTime = endTime - startTime;
  console.log(`请求完成，响应时间为 ${responseTime} 毫秒`);
}
// 模拟实时进程的并发请求
async function makeConcurrentRequests() {
  const tasks = [
    { time: 1000 },
    { time: 2000 },
    { time: 3000 }
  ];
  const promises = tasks.map(task => processTask(task));
  await Promise.all(promises);
  const endTime = new Date();
  const responseTime = endTime - startTime;
  console.log(`所有请求完成，总响应时间为 ${responseTime} 毫秒`);
}
makeRequest();
makeConcurrentRequests();
