Vue项目报错：Uncaught SyntaxError: Unexpected token <

[wangzhiyao66]

1. Vue and Typescript Projects built
   2.I want to use webworker to count user data,
2. The code snippet is as follows
   // webworker.js
   `
   onmessage = function (event) {
   // postmessage的参数
   const eventData = {
   token: event.data.token,
   requestData: event.data,
   url: event.data.url,
   }

// 请求地址 在 worker.service.ts 里面

const sleep = function (time) {
/**
*
* @param {} data 请求参数
* @param {} callback 请求成功回掉函数
*/
var xhr = function (data, callback) {
// console.log('worker 参数', data);
const workerdata = JSON.parse(JSON.stringify(data));
if (workerdata) {
delete workerdata.token;
delete workerdata.url;
}
// fetch 请求方式
fetch(eventData.url, {
body: JSON.stringify(workerdata), // must match 'Content-Type' header
headers: {
"Authorization": "Bearer " + eventData.token,
"Content-Type": "application/json;charset=UTF-8"
},
method: 'POST', // *GET, POST, PUT, DELETE, etc.
})
.then(res => {
if (res.ok) {
return res.json();
}
throw new Error('Network response was not ok.');
})
.then(function (data) {
// console.log(JSON.stringify(data));
// console.table(data);
console.log('%c webworker请求成功 fetch方式 开始收集数据', 'color:orange');
callback();
}, function (err) {
console.error(err);
})
.catch(error => console.error('Error:', error))
}

return new Promise(function (resolve, reject) {
  const obj = {
    data: 'ok',
    type: 'worker'
  };

  xhr(eventData.requestData, function () {
    resolve(obj);
  });
});

};

// 立即执行的 async 函数
(async () => {
const result = await sleep(event.data);
postMessage(result);
// console.log('在使用importScripts()的文件中调用：' + kk());
close();
})();
};
`
// An error occurred during a method call

`
if (typeof Worker !== 'undefined') {
this.worker = new Worker('../../../../../static/js/webworker.js'); // 需要每次都调用打开一个woker
console.log( 'msg =========', msg);

        // 可以序列化为JSON结构的任何值都可以作为参数传递给 postMessage();
        this.worker.postMessage(msg);
        this.worker.onmessage = (event: any) => {
          this.worker_data = event.data;
        };
        console.log('start Web Workers...');
      } else {
        console.log('Sorry, your browser does not support Web Workers...');
      }
