如何打开下载的文件？ [英] How to open a downloaded file?

问题描述

我有一个链接到文件。我怎么知道用户点击链接并下载文件？我需要获得downloadId？ Google Chrome API有一个方法chrome.downloads.open（integer downloadId）。但我怎么知道downloadId，打开这个文件？您可以尝试下面的代码，在谷歌浏览器版本38.0.2125.111 m（64位）中测试该代码示例。

  chrome.downloads.onChanged.addListener（function（detail）{
 console.log（Detail，detail ）; //保存日志以进行调试
 
 //如果文件下载完成
 if（detail.state.current ==complete）{
 
 var downloadId = detail.id; //下载ID 
 
 console.log（下载ID，downloadId）; //保存日志以进行调试
 / * 
做某事
 * / 
 
} 
}）; 
  

I have a link to the file. How do I know that the user clicked on the link and download the file? I need to get downloadId? Google Chrome API has a method chrome.downloads.open (integer downloadId). But how do I know downloadId, to open this file? Help me please.

解决方案

You can try this example code below tested in Google Chrome Version 38.0.2125.111 m (64-bit)

chrome.downloads.onChanged.addListener(function (detail){
console.log("Detail",detail); //Save log for debugging

    //if file download finished
   if(detail.state.current == "complete"){

       var downloadId = detail.id; //Download ID

       console.log("Download ID",downloadId); //Save log for debugging
       /*
       Do Something
        */

   }
});
