如何将输入从 MainThread 发送到节点 js 中的工作线程(Worker_threads)

[英]how to send input from the MainThread to the worker thread in node js (Worker_threads)

所以我有这段代码,我想在主线程中获取输入,然后将其提供给工作线程,所以我不必将问题放在工作线程中,所以问题重复

const { Worker, isMainThread } = require('worker_threads');
if (isMainThread) {
let x = prompt("question")
for (let i = 0; i < 2; i++) {
    new Worker(__filename,);
    }
  // This re-loads the current file inside a Worker instance.
} else {

console.log(x)
  console.log('Inside Worker!');
  console.log(isMainThread);  // Prints 'false'.
}

您好,您可以使用 Worker 数据,因此请发送变量

const { Worker, isMainThread ,workerData } = require('worker_threads');

    if (isMainThread) {
      x = "hello world" ;
    for (let i = 0; i < 1; i++) {
        new Worker(__filename,{ workerData: x });
        }
      // This re-loads the current file inside a Worker instance.
    } else {
      
    console.log(workerData)
      console.log('Inside Worker!');
      console.log(isMainThread);  // Prints 'false'.
    }

to be able to send multiple variables you can assign the workerdata to a Json something like this. 
const {
  Worker,
  isMainThread,
  workerData,
  SHARE_ENV,
} = require("worker_threads");
if (isMainThread) {
  x = "hello world";
  let y = "hello";
  for (let i = 0; i < 1; i++) {
    new Worker(__filename, {
      workerData: {
        x: x,
        y: sun,
      },
    });
  }
  //) This re-loads the current file inside a Worker instance.
} else {
  console.log(workerData.y);
  console.log("Inside Worker!");
  console.log(isMainThread); // Prints 'false'.
}
