delphi调用C# WebService 出错？

[whynozg2007]

C# WebService中的函数
[WebMethod]
public string Test_Pro(string vString)
{
return vString;
}

Delphi中调用为：
var
d:ServiceSoap;
begin
d:=GetServiceSoap();
Caption:= d.Test_Pro('asdasdasdasd');

但是调用出错,但是VS调试又是正确的，不晓得怎么办？

[Bear_hx]

帮你提前

[cangwu_lee]

说说调用的具体，这样看不出什么问题来。

[lextm]

没记错的话需要用HttpRIO，不知道你怎么用ServiceSoap。

我也遇到了类似问题.

报什么错也不写,叫人如何帮你?

[lexchou]

InvRegistry.RegisterInvokeOptions(TypeInfo(XXXXXXSoap),ioDocument);
在生成的Service.pas的initialization里面加上这么一句话

[loskill]

搞毛啊，出了什么错也不说。

[jxauyhj]

var
ITelWebServiceSoap :TelWebServiceSoap;
RoutesObj : ArrayOfRoute;
error : ErrorInfo;
begin
ITelWebServiceSoap :=(HTTPRIO1 as TelWebServiceSoap);//这样转一下
error:=ITelWebServiceSoap.CheckUser('aa','aa');
Memo1.Lines.Clear;
if error.m_bERROR=false then
begin
Memo1.Lines.Add(错误信息!'+error.m_ERROR_INFO);
exit;
end;
ITelWebServiceSoap.GetRouteListByCode('aa',2,Surveyid.Text,error,RoutesObj);
if error.m_bERROR=false then //---³ö´í ûÓлñÈ¡µ½Êý¾Ý
begin
Memo1.Lines.Add(取得数据:'+error.m_ERROR_INFO);
end
else
begin
Memo1.Lines.Add(IntToStr(Length(RoutesObj)));
end;
ITelWebServiceSoap.Exit;
end;

[geoffe]

我也遇到类似的错误，unable to retrive the url endpiont......
用的是 “hongqi162”的一样方法

[helodd]

C# 的webservices 要想有delphi 调通,服务端要加上 [SoapRpcService(RoutingStyle=SoapServiceRoutingStyle.SoapAction)]

这个参数吧

[weixin_1374426001]

直接用自动生成接口里的方法,看明白每步是做什么的再写

[songfuqiang]

你可以在IE中输入地址看行不?如果都行了哪就让delphi行动形成接口.调用方法:
HTTPRIO1:=THTTPRIO.Create(Application);
Area:=nil;
HTTPRIO1.WSDLLocation:='http://locahost:8080/services/MandiQ?wsdl';//java写的Web Services的访问方法
try
(HTTPRIO1 as MandiQPortType).getAllTradeBig;
except
Application.MessageBox('连接Web Service失败!','提示',MB_ICONERROR );
end;
