QT5的问题，具体形容在下面，请大神帮忙看一下

图片说明
输入条形码查询显示在最下面的Qlineedit中然后输入库存回车显示tableview中获取信息用的qnetwork这已经完成了，但是第一次输条形码回车输库存回车显示一条信息，第二次就变成2条同样的了，第三次三遍了，求助大神，求帮助啊,下面贴了代码图片说明上传的错误如上图，图片上的网络错误已经解决，上传状态都正常，只是上传数量的错误一直没有解决，第一条传了一遍，第二条传了两遍，第三条传了三遍

看下代码，估计是你使用的是相同的对象或者结构体，所以循环中修改它实际上冲掉了以前的，应该为每个条目new一个结构体或者对象，再赋值。

那楼主每次回车输入结束后先清空一下你的控件
楼主用的是啥显示控件？qtableWidget？

看情况或者是保存查询结果的变量没有清，最可能是table没有清除！

这是代码，里面我给删了三句，但不影响看，请大神看看是哪里出了问题
