node-webkit浏览器插件注册升级方式
node-webkit浏览器插件注册升级方式,调用srver32,reg等系统层方法来实现。本人对这些方法封装实现了插件检查是否注册，注册表插件版本检查，升级功能,写成一个公共模块分享出来。
var async = require('async');
var path = require('path');
var exec = require('child_process').exec;
var gui = global.window.nwDispatcher.requireNwGui();
/*插件对像格式，要传入这个格式的对像去执行各项操作*/

dll:[path.join(__dirname,"../../lib/ScreenCapture/ScreenCaptureKTP.dll")],
path:path.join(__dirname,"../../lib/ScreenCapture/chrScpCapKTP.dll")
}
var Register = function(){
var THIS=this;
/* 注册系统组件
*输入DLL文件名时，如果待处理的是非系统文件，必须在文件名前添加文件绝对路径，必须注意的是文件路径不包含中文，否则很可能导致处理失败。
*regsvr32 [/u] [/s] [/n] [/i[:cmdline]] DLL文件名

var regStr ="regsvr32 /s"+ parm+" "+dllPath;
console.log("REG32",regStr)
exec(regStr,{encoding: 'utf8'},callback);
}catch(err){
console.err("注册系统组件失败",err)
callback("注册系统组件失败"+err);

/* 注册表注册
* method 类别： "add"|| "delete"||"query"
* keyName 名称，如： "HKEY_CURRENT_USER\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run"

* value 写入值, "String"
* valueType 值类型, "REG_SZ"等注册表值类型
* force bool, 强行覆盖已存在的键值
