javascript - 如何使用 node.js 创建一个 ActiveXObject？

Question

我是 node.js 的新手。我正在尝试使用 node.js 实现浏览器性能工具，所以我有以下代码:

 for(var j=0; j < 14; j++) {
        // Create a new instance of HttpWatch in Firefox
        var control = new ActiveXObject('HttpWatch.Controller');
        var plugin = control.Firefox.New();
        // Start Recording HTTP traffic
        plugin.Log.EnableFilter(false);
        // Clear Cache and cookier before each test
        plugin.ClearCache();
        plugin.ClearAllCookies();   
        plugin.ClearSessionCookies();
        plugin.Record();
        // Goto to the URL and wait for the page to be loaded
        plugin.GotoURL(url);
        control.Wait(plugin, -1);
        // Stop recording HTTP
        plugin.Stop();
        if ( plugin.Log.Pages.Count != 0 )
        {           
           // Display summary statistics for page
           var summary = plugin.Log.Pages(0).Entries.Summary;
           //WScript.Echo( "Iteration number " + j + "for" + url + "   Total time to load page in (secs): " + summary.Time);
           cache[i].value.push(summary.Time);
        }
        // Close down Firefox
        plugin.CloseBrowser();
      }

我正在使用 httpwatch 来测量性能值，这些值将存储在 MySQL 数据库中。 但是，当我运行时:

node test.js

我得到:

C:\xampp\htdocs\test\browser-perf>node test.js

C:\xampp\htdocs\test\browser-perf\test.js:37
                var control = new ActiveXObject('HttpWatch.Controller');
                                  ^
ReferenceError: ActiveXObject is not defined

如何在 node.js 中创建与 ActiveXObject 类似的对象并获得相同的预期结果？

https://npmjs.org/package/win32ole

尝试安装 win32ole 包，打开 node.js cmd，然后键入以下内容来安装包。

npm install win32ole

示例用法:

var win32ole = require('win32ole');
var xl = win32ole.client.Dispatch('Excel.Application');
xl.Visible = true;
