DELPHI客户端访问WEBSERVICE方法
1. 首先取得java-webservice服务器端地址。我的是：http://localhost:8080/mywebservice/services/mywebservice?wsdl
2. 然后打开delphi7，file-new-other:选择WebService选项卡,在选择WSDLImporter ,在弹出的界面中输入java-webservice地址。点击Next-finish.会生成一个.pas的webservice文件，
生成的代码如下： Java代码 收藏代码 // ************************************************************************ // // The types declared in this file were generated from data read from the // WSDL File described below: // WSDL : http://localhost:8080/mywebservice/services/mywebservice?wsdl // Encoding : UTF-8 // Version : 1.0 // (2011-7-21 10:17:02 - 1.33.2.5) // ************************************************************************ // unit mywebservice; interface uses InvokeRegistry, SOAPHTTPClient, Types, XSBuiltIns; type // ************************************************************************ // // The following types, referred to in the WSDL document are not being represented // in this file. They are either aliases[@] of other types represented or were referred // to but never[!] declared in the document. The types from the latter category // typically map to predefined/known XML or Borland types; however, they could also // indicate incorrect WSDL documents that failed to declare or import a schema type. // ************************************************************************ // // !:int - "http://www.w3.org/2001/XMLSchema" // !:string - "http://www.w3.org/2001/XMLSchema" // ************************************************************************ // // Namespace : http://server // transport : http://schemas.xmlsoap.org/soap/http // style : document // binding : mywebserviceHttpBinding // service : mywebservice // port : mywebserviceHttpPort // URL : http://localhost:8080/mywebservice/services/mywebservice // ************************************************************************ // mywebservicePortType = interface(IInvokable) ['{56F18980-71B1-FAC0-BFF5-569F621A8591}'] function add(const a: Integer; const b: Integer): Integer; stdcall; function sayHello(const name: WideString): WideString; stdcall; end; function GetmywebservicePortType(UseWSDL: Boolean=System.False; Addr: string=''; HTTPRIO: THTTPRIO = nil): mywebservicePortType; implementation function GetmywebservicePortType(UseWSDL: Boolean; Addr: string; HTTPRIO: THTTPRIO): mywebservicePortType; const defWSDL = 'http://localhost:8080/mywebservice/services/mywebservice?wsdl'; defURL = 'http://localhost:8080/mywebservice/services/mywebservice'; defSvc = 'mywebservice'; defPrt = 'mywebserviceHttpPort'; var RIO: THTTPRIO; begin Result := nil; if (Addr = '') then begin if UseWSDL then Addr := defWSDL else Addr := defURL; end; if HTTPRIO = nil then RIO := THTTPRIO.Create(nil) else RIO := HTTPRIO; try Result := (RIO as mywebservicePortType); if UseWSDL then begin RIO.WSDLLocation := Addr; RIO.Service := defSvc; RIO.Port := defPrt; end else RIO.URL := Addr; finally if (Result = nil) and (HTTPRIO = nil) then RIO.Free; end; end; initialization InvRegistry.RegisterInterface(TypeInfo(mywebservicePortType), 'http://server', 'UTF-8'); InvRegistry.RegisterDefaultSOAPAction(TypeInfo(mywebservicePortType), ''); InvRegistry.RegisterInvokeOptions(TypeInfo(mywebservicePortType), ioDocument); InvRegistry.RegisterExternalParamName(TypeInfo(mywebservicePortType), 'add', 'out_', 'out'); InvRegistry.RegisterExternalParamName(TypeInfo(mywebservicePortType), 'sayHello', 'out_', 'out'); end.
3.
新建一个form窗体，拖入一个Button和一个edit控件。 在窗体的uses部分加入InvokeRegistry, Rio, SOAPHTTPClient, mywebservice。 为Button添加click事件。 Java代码 收藏代码 procedure TForm1.Button1Click(Sender: TObject); var server:mywebservicePortType;//此处为delphi生成的java-webservice的方法名。 aa:string; begin server:=GetmywebservicePortType(true,'',nil);//delphi生成的方法 showmessage(server.sayHello(Edit1.Text));//调用java-webservice的sayHello()方法。 end;
到此，delphi调用java的webservice服务器端程序示例已经完成。
