增值税电子普通发票：
01,10,011001800211,65651348,105.46,20180709,05903676700178588016,C62D,

该字符串以逗号分隔每一个属性值，从左到右依次是：

01：第一个属性值，尚未搞清楚含义；

10：第二个属性值，代表发票种类代码，10-增值税电子普通发票，04-增值税普通发票，01-增值税专用发票；

011001800211：第三个属性值，代表发票代码；

65651348：第四个属性值，代表发票号码；

105.46：第五个属性值，代表开票金额；

20180709：第六个属性值，代表开票日期，该值为2018年7月9日；

05903676700178588016：第七个属性值，代码发票校验码，我们都知道增值税专用发票是没有发票校验码的，没有则为空字符串；

C62D:第八个属性值，为随机产生的机密信息；

增值税专用发票:
01,01,1200154130,03630024,94339.62,20180721,,AE2D, 　

其中"AE2D"为随机产生的机密信息；

增值税普通发票:
