javascript - 未捕获的网络错误 : Failed to execute 'importScripts' on 'WorkerGlobalScope'

Question

我正在尝试使用 importScripts 从 web worker 导入 json 数据，出现以下错误。

Uncaught NetworkError: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at (my:URL to fetch data from server) failed to load.

网络 worker 代码在这里。我能够从我的网络工作线程和主 js 线程发送基本消息。我想从我的服务器从网络工作线程获取 jsonp 数据，然后回复主 js 线程。

/*web worker js file to fetch json data from server and then return to main javascript thread*/

self.onmessage = function(e)
{
    var curr = setInterval(function()
    {
    
         var message = e.data;     
            fetchMyTournament(message);
    
    }, 10000);
}



function fetchMyTournament(userid)
{
    self.postMessage('worker saying hi');
       
    
    var url = "(server URL mapping)?callback=processInfo&type=(typeOfArgument)&userId="+userid;
    
               
               
               importScripts(url);
            self.postMessage("After import script");

            
       
}
function processInfo(objJSON) 
{
 
    self.postMessage("Data returned from the server...: " 
                  + JSON.stringify(objJSON));
}

就我而言，我是这样导入 PouchDB 的:importScripts("//cdn.jsdelivr.net/pouchdb/5.3.1/pouchdb.min.js");

网址应以正确的 http/https 开头。所以改成这个解决了问题:importScripts("https://cdn.jsdelivr.net/pouchdb/5.3.1/pouchdb.min.js");
