标题: 将QC的COM接口开放成Rest服务
<原文发表在:http://charlescui.javaeye.com/blog/518335>;

以Ruby代码为例，

QC平台的SDK以COM组件的形式对外开放，但这种开放方式只限于本机，如果需要进行远程访问QC开放的接口，需要对这套SDK包装一下，做成标准化的远程通讯协议或方式，比如：ice或者rest。

我的设计是将COM用Ruby包装一下，做成一个对外提供Rest方式接口的QCMetaServer服务器。 过程如下：


首先要访问QC的COM组件，建立全局连接，需要的话可以放到公用的池子里。Ruby做成服务发布的时候通常是按多进程方式发布的，所以一般一个进程一个连接就够了，不需要池子。

其次将所需的所有COM接口封装一下，变成Rest接口，这样可以和其它远程服务器进行通讯。

最后，注意在服务器终止之前释放连接，否则QC的COM会报错：

QCMetaServer.rb:112: [BUG] Segmentation faultruby 1.8.6 (2008-08-11) [i386-mswin32]This application has requested the Runtime to terminate it in an unusual way.Please contact the application’s support team for more information.
QCMetaServer.rb:112: [BUG] Segmentation fault ruby 1.8.6 (2008-08-11) [i386-mswin32] This application has requested the Runtime to terminate it in an unusual way. Please contact the application’s support team for more information.

这个错误对于公司内部少数人使用的情况下没有多大影响，但这种设计对生产环境上的应用来说是不允许的。

对QC接口二次开发之前，需要了解下QC SDK，相关资料请各位网上搜索，我这里资料有限，本人也是边看少而又少的资料，边猜测着开发的。

下面这个图大家引用的较多，这是QC COM中的SDK方法的树状结构图，绝大部分对象都是通过工厂方法生成的，这是规律。


(大家能看见图片么?我编辑的时候可以,发表后不行)

代码如下：

Ruby代码
require 'rubygems'  
require 'activerecord'  
require 'win32ole'  
require 'pp'  
  
p "Global initializion."  
$qc = WIN32OLE.new("TDApiOle80.TDConnection")  
p "Loaded COM => TDApiOle80.TDConnection"  
$qc.InitConnectionEx("http://10.2.226.12/qcbin/");  
p "QC connection init."  
$qc.ConnectProjectEx('ALISOFT_CRM','ALISOFT_CRM2006','cuizheng','');  
p "QC project connection init."  
  
require 'sinatra/base'  
require 'coderay'  
  
class QCMeta < Sinatra::Base  
  
  get '/' do  
    h = {}  
    h[rojectName] = $qc.ProjectName  
    h[:ServerURL] = $qc.ServerURL  
    h[:ServerTime] = $qc.ServerTime  
    h[rojectProperties] = $qc.ProjectProperties  
    h[:ServerName] = $qc.ServerName  
    h.to_xml  
  end  
   
  get '/ole' do  
    h = {  
      "TDApiOle80.TDConnection<functional>" => $qc.ole_func_methods.map{|f|f.to_s},  
      "TDApiOle80.TDConnection<property(get)>" => $qc.ole_get_methods.map{|f|f.to_s},  
      "TDApiOle80.TDConnection<property(set)>" => $qc.ole_put_methods.map{|f|f.to_s}  
    }.to_json  
    params[:color].downcase == "true" ? CodeRay.scan(h,:json).div(:line_number => :tables) : h  
  end  
   
  get '/projects' do  
    {rojectsList => $qc.ProjectsList}.to_xml  
  end  
  
=begin  
  <C#>  
  
  int intSub = 286;  
  SubjectNode nodSub = objTree.get_NodeById(intSub) as SubjectNode;  
  TestFactory objTF = nodSub.TestFactory as TestFactory;  
  lstList = objTF.NewList("");  
  foreach (Test objTest in lstList)  
  {  
  MessageBox.Show((string)objTest.Name);  
  }  
=end  
  
  #~ tm = $qc.TreeManager  
  #~ nod = tm.get_NodeById(id)  
  #~ nod.TestFactory.NewList("").each do |test|  
    #~ pp test.Status  
  #~ end  
  
  
=begin  
  <VB>  
  Dim BugFactory, BugList  
  Set BugFactory = QCConnection.BugFactory  
  Set BugList = BugFactory.NewList("") 'Get a list of all the defects.  
=end  
  
  
  
  get "/bugs" do  
    bf = $qc.BugFactory  
    bflist = bf.NewList("")  
  
    max = params[:max] || 100  
    i = 0  
    h = {}  
    bflist.each do |bug|  
      h[bug.ID] = {  
        :Status => bug.Status,  
        :AssignedTo => bug.AssignedTo,  
        etectedBy => bug.DetectedBy,  
        riority => bug.Priority,  
        :Summary => bug.Summary  
      }  
      i >= max ? break : i+=1  
    end  
    {:BUGS => h,:COUNT => bflist.Count}.to_xml  
  end  
   
  def self.run!(options={},&trap_handler)  
    set options  
    handler      = detect_rack_handler  
    handler_name = handler.name.gsub(/.*::/, '')  
    puts "== Sinatra/#{Sinatra::VERSION} has taken the stage " +  
      "on #{port} for #{environment} with backup from #{handler_name}" unless handler_name =~/cgi/i  
    handler.run self, :Host => host, ort => port do |server|  
      trap(:INT) do  
        trap_handler.call  
        ## Use thins' hard #stop! if available, otherwise just #stop  
        server.respond_to?(:stop!) ? server.stop! : server.stop  
        puts "\n== Sinatra has ended his set (crowd applauds)" unless handler_name =~/cgi/i  
      end  
      set :running, true  
    end  
  rescue Errno::EADDRINUSE => e  
    puts "== Someone is already performing on port #{port}!"  
  end  
end  
  
  
QCMeta.run!(:host=>'0.0.0.0', :port => 4567){  
  begin  
    $qc.DisconnectProject  
    p "QCMeta disconnected to QC."  
    $qc.ReleaseConnection  
    p "QCMeta released to QC."  
    p "QCMeta will shutdown."  
    rescue => e  
    p "QCMeta disconnect and release faile."  
    p "But server still going to shutdown."  
    p e.to  
  end  
}  


服务器启动后，访问如下几个url可得到相应的结果：

标题: 大哥你太有才
可是~你搞这么个代理~是如何应用？我用C#的访问QC老出问题
