WEB Service新手學習遇到的困難 ( 积分: 200 )

一年多前有了解一下WEB SERVICE，當時選了COM+的HTTP方式連接，現在想試著改成WEB SERVICE，所以翻出舊書學習，但第一個DEMO就遇阻，比較打擊信心

客戶端兩種方式都出錯，接口不支持。
uses SayHelloIntf;
procedure TForm1.Button1Click(Sender: TObject);
begin
HTTPRIO1.WSDLLocation := 'http://localhost/Scripts/Project1.dll/wsdl/ISayHello';
Edit1.Text := (HTTPRIO1 as ISayHello).SayWithName('Yuan');
//李維老師的書上是用的這種
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
SoapConnection1.URL := 'http://localhost/Scripts/Project1.dll/wsdl/ISayHello';
Edit1.Text := SoapConnection1.AppServer.SayWithName('Yuan');
end;

謝謝各位前輩/過來人的舉手之勞。

就是在李維老師的D6/K2 SOAP/Web Service程序設計
第3章，第60頁
程序能編輯通過，但不能運行

在D7的DEMO目錄裡，還找到一種方法，但仍然報接口不支持的錯誤
(SoapConnection2.GetSOAPServer as ISayHello).SayWithName('Yuanjun');

没看清,不过D6做的webservice服务器有BUG,最好不要用

[] 我用的是D7, Win2000IIS
还有没有大哥帮帮我啊
WSDL有了。连接也连上了，就是不能调用。SoapConnection2, HTTPRIO1两种都不行啊

Received content of invalid Content-Type setting: text/html - SOAP excepts &quot;text/xml&quot;
出了新狀況，這個錯誤跑出來了。還有HTTPRIO1的WSDLLocation屬性不同時出了個小錯
http://localhost/Scripts/Project2.dll/wsdl/IWM2 正常
http://localhost/Scripts/Project2.dll/soap/IWM2 再選service屬性就不正常，報錯接口不支持
wsdl/soap的區別

要暈了，有沒有前輩指點一下啊。晚上睡覺前看能不能解決了

... 有些失望，很久沒來大富翁了，還是這樣，提的問題不能解決，也許是我問題提的不好。
打開D7的DEMO後發現了，原來是接口函數要定義成stdcall。

接受答案了.
