访问webservice,导入xml至本地数据集

标签：delphi   webservice   xml   

1. 创建本地数据集
   

    clientdataset2.FieldDefs.Clear;;
     with clientdataset2.FieldDefs.AddFieldDef do
     begin
       Name := ‘id‘;
       Size := 10;
       DataType := ftString;
     end;
     with clientdataset2.FieldDefs.AddFieldDef do
     begin
       Name := ‘xm‘;
       size := 10;
       DataType := ftstring;
     end;
     with clientdataset2.FieldDefs.AddFieldDef do
     begin
       Name := ‘xb‘;
       Size := 10;
       DataType := ftString;
     end;
     with clientdataset2.FieldDefs.AddFieldDef do
     begin
       Name := ‘nl‘;
       DataType := ftinteger;
     end;
     with clientdataset2.FieldDefs.AddFieldDef do
     begin
       Name := ‘sfzh‘;
       Size := 10;
       DataType := ftString;
     end;
     with clientdataset2.FieldDefs.AddFieldDef do
     begin
       Name := ‘jtzz‘;
       size := 30;
       DataType := ftstring;
     end;
     clientdataset2.CreateDataSet;
     clientdataset2.open;

2. 导入xml

   var
     xml:Tnativexml;
     root: TsdElement;
     i:integer;
     ////////////声明soapheader
     aIntf: DataCenterServicesSoap;
     Headers: ISOAPHeaders;
     H: SecuritySoapHeader2;//SecuritySoapHeader2;
   begin
     Try
       clientdataset2.EmptyDataSet;
       xml := Tnativexml.Create(nil);
   
       ////////////////////////////////////////////////////发送soapheader
       aIntf := (httprio1 as DataCenterServicesSoap);
   
       H := SecuritySoapHeader2.Create;
       h.Ticket := ‘BE2E4F35-CDE9-46A1-844B-9FB2546491B2‘;
   
       Headers := (aIntf as ISOAPHeaders);
       Headers.Send(H); //发送Soap Header
      // xml.ReadFromString((httprio1 as DataCenterServicesSoap).getdataasxml(memo1.Text));
       //aIntf.GetInfo; //调用服务
       xml.ReadFromString((httprio1 as DataCenterServicesSoap).GetXML(memo1.Text));
       xml.XmlFormat := xfReadable;
       root := xml.Root;
       for i := 0 to root.NodeCount - 1 do
       begin
         clientdataset2.Append;
         clientdataset2.FieldByName(‘id‘).Value := root[i].NodeByName(‘ID‘).Value;
         clientdataset2.FieldByName(‘xm‘).Value := root[i].NodeByName(‘xm‘).Value;
         clientdataset2.FieldByName(‘xb‘).Value := root[i].NodeByName(‘xb‘).Value;
         clientdataset2.FieldByName(‘nl‘).Value := root[i].NodeByName(‘nl‘).Value;
         clientdataset2.FieldByName(‘sfzh‘).Value := root[i].NodeByName(‘sfzh‘).Value;
         clientdataset2.FieldByName(‘jtzz‘).Value := root[i].NodeByName(‘jtzz‘).Value;
         clientdataset2.Post;
       end;
     finally
       aIntf := nil;
     End;
   
     xml.Free;
     H.Free;
