Delphi6利用WebService 编写 SendEMail程序

 到http://www.xmethods.com

就会看到一个Delphi做的服务器程序. Send an EMail

有如下描述:

我们下载程序接口:

点WSDL URL连接

另存为名为IEmailService.wsdl到你的程序相同目录.

导入程序接口:

然后会生成Unit2单元.

Unit Unit2;

interface

uses Types, XSBuiltIns;
type

  IEmailService = interface(IInvokable)
    ['{839561DB-8AFE-43B8-81EB-5505C873EC8F}']
    function SendMail(const ToAddress: WideString; const FromAddress: WideString; const ASubject: WideString; const MsgBody: WideString): Integer;  stdcall;
  end;

implementation

uses InvokeRegistry;

initialization
  InvRegistry.RegisterInterface(TypeInfo(IEmailService), '', '');

end.

选择刚才保存的wsdl文件给HTTPRIO1.WSDLLaction属性

在Unit1中运行编程

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs,  Rio, SoapHTTPClient, StdCtrls, ExtCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    HTTPRIO1: THTTPRIO;
    LabeledEdit1: TLabeledEdit;
    LabeledEdit2: TLabeledEdit;
    LabeledEdit3: TLabeledEdit;
    Memo1: TMemo;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

uses Unit2;  /////////////

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
  if (HTTPRIO1 as IEmailService).SendMail
    (LabeledEdit1.Text,
     LabeledEdit2.Text,
     LabeledEdit3.Text,
     Memo1.Text
    ) = 0 then
    ShowMessage('Send Success!');
end;

end.

可以发邮件了,很方便也很简单.
