服务器的Java传感器id

我目前正在做一项使用Phidges的作业。我有这段代码，它输出phidgets详细信息，如序列号、设备版本及其值。我可以让它把序列号打印到控制台上

System.out.println("Serial Number " + phid.getSerialNumber()); 

如何将其添加到服务器上的字符串fullURL中

String fullURL = sensorServerURL + "?sensorname=rotationsensor&sensorvalue="+sensorValue;

任何帮助都将不胜感激，我的任务截止日期是今晚11点，这个问题困扰了我一段时间，似乎无法解决：/

您不能将序列号保存在变量上，并使用另一个参数构建

fullUrl

fullURL=sensorServerURL+“？sensorname=rotationsensor&sensorvalue=“+sensorvalue+”&serialNumber=“+serialNumberVariable您需要将其作为参数添加到url，您已经有了类似的东西&sensorvalue=“+sensorvalue”。您需要实例&serialNumber=phid.getSerialNumber（）添加到url。不幸的是，要正确处理它，您需要对服务器端进行一些更改。您不能将serialNumber保存在变量上，并使用另一个参数构建
