如何将LUA表与变量长度合并到另一个LUA表中。

在FOR-LOOP中我想搜索记录（plunr和pluname）并放在表格中。如果每个记录都放在表中，我将把这个表合并到另一个＆＃34;请求表＆＃34;

问题是只有最后一条记录被发送到网络服务器。

 for rrplu in receipt:getPLUs() do
   local plunr = rrplu:getPLUNo();
   local pluname = rrplu:getName();
   plutable = { tag = "hot1:TicketDetail",
                                    { tag = "hot1:PLU", plunr},
                                    { tag = "hot1:Description", pluname},
                                }     

 end;

 local soap_client = vpos.communication.SOAPClient (http)
 local request = {
    url = urlHTTPS,
    soapaction = "http://blablabla.com/IXmlPosService/Charge",
    namespace = {hot="http://blablabla.com/",
    hot1="http://schemas.datacontract.org/2004/07/BlaBla.Web.DataContracts"},
    method = "hot:Charge",
    body =  { tag = "hot:Charge",
                    { tag = "hot:authentication",
                    { tag = "hot1:Token", TokenValue},
                    },
                    { tag = "hot:request",
                    { tag = "hot1:PosDate", datum},
                    { tag = "hot1:TicketDetails",
                    plutable
                    },
                    },
                    }
                }
   result, err, err_string = soap_client:call (request)

每次循环都会将plutable设置为新表。您可能希望插入新表或现有表。

将plutable =替换为

plutable = plutable or {}
table.insert(plutable, { 
    tag = "hot1:TicketDetail",
    { tag = "hot1:PLU", plunr },
    { tag = "hot1:Description", pluname }})
