Delphi7 调用VS.NET 2005开发的基于.NET 2.0的WebService时发生了错误。查阅资料 http://www.community.borland.com/article/borcon/files/4132/paper/4132.html 发现原来Delphi7客户端虽然支持WebService的RPC|Encoded 和 Document|Literal编码，但 默认的是使用RPC。而.NET 2.0下的WebService却是默认采用Documnet|Literal编码的。因此我们需要显示地声明让Delphi客户端采用Documnet|Literal编码就可以了。在Delphi的WSDL Importer产生了WebService的接口文件中加入如下行：
initialization
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.
