InvRegistry.RegisterInterface(TypeInfo(ServiceSoap), 'http://tempuri.org/', 'utf-8'); InvRegistry.RegisterInvokableClass(ServiceSoapImpl); InvRegistry.RegisterDefaultSOAPAction(TypeInfo(ServiceSoap), 'http://tempuri.org/HelloWorld'); InvRegistry.RegisterInvokeOptions(TypeInfo(ServiceSoap), ioDocument);//指明Delphi采用Document编码 end. 如果需要在WebService中传送汉字的参数,则建议在Service.pas中再添加一行代码
function GetServiceSoap(UseWSDL: Boolean; Addr: string; HTTPRIO: THTTPRIO): ServiceSoap;
const defWSDL = 'http://localhost/myservice/service.asmx?wsdl'; defURL = 'http://localhost/myservice/service.asmx'; defSvc = 'Service'; defPrt = 'ServiceSoap'; 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; RIO.HTTPWebNode.UseUTF8InHeader := True; //添加该行,指定采用UTF-8代码传输 try Result := (RIO as ServiceSoap); 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; 需要说明的是使用Delphi2006则不需要上述的改变即可以正确调用VS.NET 2005书写的WebService. |
