如何使用node.js创建ActiveXObject？

Question

我是个新手node.js.我正在尝试使用node.js实现一个浏览器性能工具,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来衡量性能值,这些值将存储在MySQL数据库中.但是,当我跑:

node test.js

我明白了:

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
    at Object.<anonymous> (C:\xampp\htdocs\test\browser-perf\test.
js:37:21)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)

    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:901:3

我怎样才能创建一个类似的对象ActiveXObject中node.js,并获得同样的预期效果？

Answer 1

https://npmjs.org/package/win32ole

尝试win32ole包,安装,打开node.js cmd,然后键入以下内容以安装包.

npm install win32ole

用法示例:

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