后端：

var http = require('http');
var fs = require('fs');

http.createServer(function (request, response) {

  if(request.url === "/") {
    fs.readFile('./test.html', (err, data) => {
      response.end(data)
    })
  } else if(request.url === "/test.js") {
    fs.readFile('./test.js', (err, data) => {
      response.end(data)
    })
  } else if(request.url === "/worker.js") {
    console.log(111)
    fs.readFile('./worker.js', (err, data) => {
      response.end(data)
    })
  } else {
    response.end("hello")
  }

}).listen(8888);

test.html：

  <script src="test.js"></script>

test.js：

    let worker = new SharedWorker('worker.js')

    worker.port.postMessage("hello")

worker.js

onconnect = (e) => {
    const port = e.ports[0]

    port.onmessage = (e) => {
        console.log(e.data)
    }
}

访问 http://localhost:8888，然后浏览器控制台 Network 里 worker.js 一直在pending，是什么问题
