客户端delphi使用XML与中间层C#.net通信的例子，客户端用idhttp的post发送请求

  1. 客户端代码：
  1. unit Unit1;
  3. interface
  5. uses
  6.   Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  7.   Dialogs, IdBaseComponent, IdComponent, IdTCPConnection, IdTCPClient,
  8.   IdHTTP, StdCtrls;
  10. type
  11.   TForm1 = class(TForm)
  12.     IdHTTP1: TIdHTTP;
  13.     Button1: TButton;
  14.     Button2: TButton;
  15.     Memo1: TMemo;
  16.     procedure Button2Click(Sender: TObject);
  17.   private
  18.     { Private declarations }
  19.   public
  20.     { Public declarations }
  21.   end;
  23. var
  24.   Form1: TForm1;
  26. implementation
  28. {$R *.dfm}
  30. procedure TForm1.Button2Click(Sender: TObject);
  31. var
  32.   respsm:TStringStream;
  33.   AList:TStrings;
  34.   uri:string;
  35. begin
  36.   uri:='http://localhost:4983/WebSite3/Default.aspx';//这个地址换成自己的响应地址
  37.   AList:=TStringList.Create;
  38.   {中文乱码问题解决方法：发送过去之前先转码UTF8Encode,接收的时候再解码UTF8Decode}
  39.   AList.Add(UTF8Encode(Memo1.Text));
  41.   respsm:=TStringStream.Create('');
  42.   //IdHTTP1.Get('http://localhost:4983/WebSite3/Default.aspx?id=3',sm);
  43.   IdHTTP1.Request.ContentType:='application/x-www-form-urlencoded';
  44.   try
  45.     IdHTTP1.Post(uri,AList,respsm);
  46.   finally
  47.     ShowMessage(UTF8Decode(respsm.DataString));//respsm.DataString为中间层返回的数据
  48.   end;
  50.   respsm.Free;
  51.   AList.Free;
  53. end;
  55. end.

客户端memo1.Text的内容为(在设计界面直接编辑memo1.lines,输入以下内容)：

  1. <?xml version="1.0" encoding="utf-8" ?>
  2. <erp>
  3. <head>
  4. </head>
  5. <body>
  6. <client job="RoleInfo_New">
  7. <main job="New" ID="" Name="测试角色3" />
  8. </client>
  9. </body>
  10. </erp>

中间层代码：（Default.aspx.cs）

  1. using System;
  2. using System.Data;
  3. using System.Configuration;
  4. using System.Web;
  5. using System.Web.Security;

  7. using System.Web.UI.WebControls;
  8. using System.Web.UI.WebControls.WebParts;
  9. using System.Web.UI.HtmlControls;
  10. //添加以下命名空间
  11. using System.Xml;
  12. using System.Data.Sql;
  13. using System.Data.SqlClient;
  14. using System.IO;
  15. using System.Text;

  53.                 comm.Prepare();
  54.                 
  55.                 comm.Parameters.Add("@Name", SqlDbType.VarChar, 50);
  56.                 comm.Parameters[0].Direction = ParameterDirection.Input;
  57.                 comm.Parameters[0].Value = AttrList[1];
  58.                 //取刚插入数据库的记录的ID
  59.                 DataSet ds = new DataSet();
  60.                 SqlDataAdapter sda = new SqlDataAdapter(comm);

  64.                 conn.Close();
  65.                 conn.Dispose();
  67.                 ID = ds.Tables[0].Rows[0][0].ToString();
  68.                 //插入成功将ID返回给客户端
  69.                 Response.Clear();
  70.                 Response.ContentType = "text/xml";
  71.                 Response.Write("<?xml version=/"1.0/" encoding=/"utf-8/" ?>");
  72.                 Response.Write("<erp>");
