Question

我们当前的项目是在Delphi 6中。这是我第一次尝试在Delphi中使用Web服务 - 我在这个领域的主要经验是使用C＃。无论如何，我需要从这个项目中使用一个Web服务。我遇到了一些问题，导入wsdl（http://txportwst.txhubpr.com/txserver/1?wsdl）会生成两个单元。这些单位存在一些问题。类型引用和依赖，使它不能立即建立，但我能够纠正这些。

从测试表单中，我添加了使用该服务的代码，但是我收到了一个没有意义的错误。该方法期望发送类型的var（requestIVULoto），但错误将指示其他情况。我从xmethods.net切换到一个随机服务，并且能够得到一个非常简单的（reto.checkit.ch/Scripts/Lotto.dll/wsdl/IgetNumbers）功能，这告诉我我是在正确的道路上，但是稍微复杂的另一个（www.xmlme.com/WSDailyNet.asmx?WSDL）并没有产生我从我需要使用的服务收到的相同错误。

我能够在C＃中使用服务参考和10行代码来获得我需要的服务，这很容易但是让Delphi更加令人沮丧。如果这不起作用，我考虑将.net类lib暴露给com。我宁愿在Delphi中这样做，但我担心Delphi 6太旧了。

有什么想法吗？

作为旁注，在C＃..

IvuLoto.IvuSvc.ivuLotoData ild = new IvuLoto.IvuSvc.ivuLotoData();
ild = client.requestIVULoto(txn); // returns type ivuLotoData.

Answer 1

我使用Delphi XE3导入了您指定的WSDL，并且无需任何修改即可正常工作（好的，我承认，我更改了单位名称）。

这是我收到的XML响应：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <ns2:requestIVULotoResponse xmlns:ns2="http://txserver.sut.softekpr.com/1">
      <IVULoto>
        <status>INVALID_PARAMETERS</status>
        <errorDetail>invalid merchantId</errorDetail>
      </IVULoto>
    </ns2:requestIVULotoResponse>
  </soap:Body>
</soap:Envelope>

这是我使用的代码：

procedure TFormMain.Button1Click(Sender: TObject);
var
  req : transaction;
  rsp : ivuLotoData;
  rio : THTTPRIO;
begin
  rio := THTTPRIO.Create(Self);
  //Compile request
  req := transaction.Create();
  req.txDate := TXSDateTime.Create;// '08/14/2014 00:00:00';
  req.txDate.AsDateTime := now;
  req.txType := txtype.SALE;
  req.merchantId := 'REMOVED';
  req.terminalId := IntToStr(112233);
  req.terminalPassword := 'REMOVED';
  req.txType := txType.SALE; //IVU.txType
  req.tenderType := tenderType.CASH; //IVU.tenderType
  req.subTotal := TXSDecimal.Create;
  req.subTotal.DecimalString := '100.00';
  req.municipalTax := TXSDecimal.Create;
  req.municipalTax.DecimalString := '1.00';
  req.stateTax := TXSDecimal.Create;
  req.stateTax.DecimalString := '6.00';
  req.total := TXSDecimal.Create;
  req.total.DecimalString := '107.00';

  //Call WS Method requestIVULoto
  rsp := GetTxServer(false, '', RIO).requestIVULoto(req);

   req.Free;
  rsp.Free;
end;

我已经研究过您的WSDL导入，但对Web服务的了解太少，无法对您的Delphi 6代码进行任何修改。

这是您的WSDL的Delphi XE3导入。我删除了大部分实现代码，因为Stack Overflow应答只能包含30000个字符。：
