  1. 监测数据采集物联网应用开发步骤(11)

本章节进行前端web UI开发+web数据接口服务开发

web数据接口服务利用SOCKET TCP服务方式解析http协议内容模式

在com.zxy.common.Com_Para.py中添加如下内容

python 复制代码 
#修改web数据接口服务端口
port = 9000
#是否启用http协议
bThread = True
#web数据接口访问函数名
Inf_Name = "CenterData"
#web文件后缀{}
web_Name = [".html", ".js", ".css", ".jpg", ".gif", ".png", ".svg", ".eot", ".ttf", ".woff2", ".woff", ".ico" ,".json", ".log",".xlsx",".xls",".vue",".dlls"]
#web数据接口返回值字段大小写，0不设置  1大写 2小写
iReturnUppLower = 1
#web数据接口TCP连接socket统计
socket_count = 0
#指定跨域访问IP xxx.xx.xx.xxx 默认为空
HttpUrl = ""
#上传文件后缀
attUpFile = ".txt|.zip|.rar|.tar|.json|.jpg|.bmp|.gif|.xls|.xlsx|.sql|.doc|.docx|"

在com.zxy.common.Com_Fun.py中添加代码

python 复制代码 
            
    #web数据接口返回值参数大小写
    @staticmethod
    def GetLowUpp(inputValue):
        if Com_Para.iReturnUppLower == 1:
            return inputValue.upper()
        elif Com_Para.iReturnUppLower == 2:
            return inputValue.lower()
        else:
            return inputValue
