file->new->other->WebService->WSDL Importer,(将C#的WSDL输入)然后delphi会自动给你生成了一个pas文件,
(比如我们当前例子的服务地址是:http://localhost/AttributeTesting/AttributeTesting.asmx
如果你想输入WSDL那么就是http://localhost/AttributeTesting/AttributeTesting.asmx?wsdl)
function GetServiceSoap(UseWSDL: Boolean; Addr: string; HTTPRIO: THTTPRIO): ServiceSoap;
const
defWSDL = ’http://localhost/webserver/Service.asmx?WSDL’;
defURL = ’http://localhost/webserver/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;
try
//RIO.HTTPWebNode.UseUTF8InHeader:=True; //
在此添加一句,修改编码方案。
Result := (RIO as ServiceSoap);
if UseWSDL then
begin
RIO.WSDLLocation := Addr;
RIO.Service := defSvc;
RIO.Port := defPrt;
end else
RIO.URL := Addr;
RIO.HTTPWebNode.UseUTF8InHeader:=True;//如果出现乱码对于中文参数必须加上
finally
if (Result = nil) and (HTTPRIO = nil) then
RIO.Free;
end;
end;
initialization
InvRegistry.RegisterInterface(TypeInfo(ServiceSoap), ’http://localhost/webserver/’, ’utf-8’);
InvRegistry.RegisterDefaultSOAPAction(TypeInfo(ServiceSoap), ’’);
//对于无法识别传入的参数的问题,需要手工加上下面这一句>......
InvRegistry.RegisterInvokeOptions(TypeInfo(ServiceSoap), ioDocument);
3.使用delphi调用上面的dll
就一个函数,没有什么好说的:
procedure TForm1.Button1Click(Sender: TObject);
type
GetNumTotal=function(a,b:integer):integer;stdcall;
var
Th:Thandle;
Tf:GetNumTotal;
Tp:TFarProc;
begin
Th:=LoadLibrary(’mywebservice.dll’); {装载DLL}
if Th>0 then
try
Tp:=GetProcAddress(Th,PChar(’GetNum’));
if Tp<>nil
then begin
Tf:=GetNumTotal(Tp);
Edit1.Text:=IntToStr(Tf(1,3)); {调用GetNumTotal函数}
end
else
ShowMessage(’GetNumTotal函数没有找到’);
finally
FreeLibrary(Th); {释放DLL}
end
else
ShowMessage(’mywebservice.dll没有找到’);
end;
public static extern int GetNum(int a, int b);
private void button1_Click(object sender, EventArgs e)
{
int a,b,i;
a=10;
b =20;
i=GetNum(a,b); //第一次比较慢(webserivce的唯一弊端!!!!)
textBox1.Text = i.ToString();
}
