跨域Web Worker? [英] Cross Domain Web Worker?

问题描述

我有 https://domain1.com (domain1)和

I have https://domain1.com (domain1) and https://domain2.com (domain2).

Domain2提供了一个包含带有此标头的javascript的页面:

Domain2 serves a page containing javascript with this header:

"Access-Control-Allow-Origin: *"

Domain1运行一些可调用的javascript代码:

Domain1 runs some javascript code that invokes:

new Worker("//domain2.com/script.js")

浏览器抛出安全异常.

自从开始写这个问题以来，我已经解决了这个问题，通过取消脚本，对其进行破坏并从中运行它来解决问题，但是我在最初的想法中遗漏了什么吗?

Since starting writing this question, I have got around this problem by ajaxing the script, blobbing it and running it from that, but am I missing something in the original idea?

I also have the same problem, hope this can help you https://gist.github.com/jtyjty99999/a730a17258fca04bfca3

 function XHRWorker(url, ready, scope) {
      var oReq = new XMLHttpRequest();
      oReq.addEventListener('load', function() {
          var worker = new Worker(window.URL.createObjectURL(new Blob([this.responseText])));
          if (ready) {
              ready.call(scope, worker);
          }
      }, oReq);
      oReq.open("get", url, true);
      oReq.send();
  }

  function WorkerStart() {
      XHRWorker("http://static.xxx.com/js/worker.js", function(worker) {
          worker.postMessage("hello world");
          worker.onmessage = function(e) {
              console.log(e.data);
          }
      }, this);
  }

  WorkerStart();
