示例 - 如何在NodeJS中调用SS生成的DLL

要想在NodeJS中调用SS生成的DLL, 需要借助EdgeJS. 

EdgeJS: http://tjanczuk.github.io/edge/

如果你还不知道如何在SS中生成DLL, 请查看: Spider Studio 新版本 (x-mas) - 可以引入第三方程序集, 可以将脚本生成为DLL

下面以曾经写过的XML/JSON互转的脚本为例 (C#中另辟蹊径解决JSON / XML互转的问题) 说明如何在NodeJS中应用SS DLL:

1. 安装edgejs

npm install edge

2. 为www.utilities_online.info.XmlJsonConverter.dll编写一个javascript的代理脚本

一共两个方法, Xml2Json & Json2Xml:

var edge = require('edge');



exports.xml2json = edge.func({

    source: function() {/*



        using System.Threading;

        using System.Threading.Tasks;

        using www.utilities_online.info;



        public class Startup

        {

            public async Task<object> Invoke(object input)

            {

                object result = null;

                Thread t = new Thread(new ParameterizedThreadStart((p) => { 

                    using(var proxy = new XmlJsonConverter())

                    {

                        proxy.Init();

                        result = proxy.Xml2Json(p.ToString());

                    }

                } ));

                t.SetApartmentState(ApartmentState.STA);

                t.IsBackground = true;

                t.Start(input);

                while (t.ThreadState != ThreadState.Stopped)

                {

                    Thread.Sleep(100);

                }

                return result;

            }

        }

    */},

    references: [ __dirname + '\\www.utilities_online.info.XmlJsonConverter.dll' ]

});



exports.json2xml = edge.func({

    source: function() {/*



        using System.Threading;

        using System.Threading.Tasks;

        using www.utilities_online.info;



        public class Startup

        {

            public async Task<object> Invoke(object input)

            {

                object result = null;

                Thread t = new Thread(new ParameterizedThreadStart((p) => { 

                    using(var proxy = new XmlJsonConverter())

                    {

                        proxy.Init();

                        result = proxy.Json2Xml(p.ToString());

                    }

                } ));

                t.SetApartmentState(ApartmentState.STA);

                t.IsBackground = true;

                t.Start(input);

                while (t.ThreadState != ThreadState.Stopped)

                {

                    Thread.Sleep(100);

                }

                return result;

            }

        }

    */},

    references: [ __dirname + '\\www.utilities_online.info.XmlJsonConverter.dll' ]

});

3. 编写服务脚本 www.utilities_online.info.XmlJsonConverter.js

var http = require('http');

var xmlJson = require('./www.utilities_online.info.XmlJsonConverter.proxy.js');



var person = { person:{ name:'Mike', age:30 }};



var proxy = http.createServer(function (req, res) {

  res.writeHead(200, {'Content-Type': 'application/xml'});

  var xml = xmlJson.json2xml(JSON.stringify(person), true);

  console.log(xml);

  res.end(xml);

}).listen(1338);
