Pass在com.zxy.main.Init_Page.py中添加如下内容
from com.zxy.tcp.ServerThreadHttp import ServerThreadHttp
@staticmethod
def Start_Http():
# 是否启用http协议接口
if Com_Para.bThread == True:
# TCP服务
temSthttp = ServerThreadHttp("", "", Com_Para.port)
t1 = threading.Thread(target=temSthttp.run, name="ServerHttpThread")
t1.start()web接口服务运行案例MonitorDataCmd.py主文件中编写：
添加如下内容:
#web数据接口服务
Init_Page.Start_Http()程序运行之后在浏览器敲入如下内容访问数据接口：
http://localhost:9000/CenterData?param_name=A01_AAA111&sub_code=&sub_usercode=
或
http://localhost:9000/CenterData?param_name=A01_AAA222&sub_code=&sub_usercode=
运行结果见图：
后台数据获取调式见：
