如何使用Firefox插件执行外部应用程序？ [英] how to execute an external application using firefox addon?

问题描述

我尝试使用nsIProcess执行.exe文件。但它不工作，不给任何错误信息。我正在努力在Firefox 10和Windows 7上。任何人都可以建议我任何解决方案？谢谢

  var file = Components.classes [@ mozilla.org/file/local;1\"].createInstance(Components。 interfaces.nsIProcess）; 
 file.initWithPath（C：\\ Users \\ 
 file.launch（）; 
  

解决方案 MJ ：

$ b

  file.initWithPath（C：\\\ \\Users\\MJ\\Desktop\\Example.FaceDetection.exe）; 
  

所以你的应用程序不执行，因为它没有被发现。也就是说，运行应用程序的更好方式通常是 nsIProcess - 它允许您指定命令line参数，它也会提供有用的反馈：
$ b

  var params = [foo，酒吧]; 
 var process = Components.classes [@ mozilla.org/process/util;1] 
 .createInstance（Components.interfaces.nsIProcess）; 
 process.init（file）; 
 process.run（false，params，params.length）; 
  

I try to execute .exe file using nsIProcess. But it is not working and not giving any error message. I am working on firefox 10 and windows 7. Can anybody suggest me any solution? Thanks

var file = Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsIProcess);
file.initWithPath("C:\\Users\MJ\\Desktop\\Example.FaceDetection.exe");  
file.launch(); 

解决方案

You forgot one backslash before MJ:

file.initWithPath("C:\\Users\\MJ\\Desktop\\Example.FaceDetection.exe");

So your application doesn't execute because it isn't being found. That said, the better way to run applications is usually nsIProcess - it allows you to specify command line parameters and it will also provide useful feedback:

var params = ["foo", "bar"];
var process = Components.classes["@mozilla.org/process/util;1"]
                        .createInstance(Components.interfaces.nsIProcess);
process.init(file);
process.run(false, params, params.length);
