"Python" Learning note 5-using flask to mock interfaces

# 1, Mock interface
# import Flask #python的轻量级的开发框架
# # interface, development of backend services
# # in the browser run Http://127.0.0.1:8080/get_user, or other way to access the interface
# server = Flask. Flask (__name__) #__name__当前文件名, take our app Python as a server
# @server. Route ('/get_user ', methods=[' get ', ' post ') #将下面函数变成一个接口
# def Get_all_user ():
#     return ' cm interface ' #return只能返回字符串
# #启动服务, plus debug Auto help restart
# Server.run (port = 8080,debug = True)


# 2, call your own module, connect to the database, browser request interface
# import Tools #使用时, need to use Tools.op_mysql ()
From lib.tools import Op_mysql  #使用时, directly with Op_mysql ()
# Both of these options are available

3, write the interface to form a standard directory structure, decomposition of the files of each directory

4, start.py run the startup program, start the service here

1 #This is the program's entry file, which will start the service command inside2 3 #add root to environment variable to facilitate directory error at underlying directory execution4 ImportSys,os5Base_path = Os.path.dirname (Os.path.dirname (Os.path.abspath (__file__)))#fetch to API directory, root directory6 Sys.path.insert (0,base_path)7 8 #Add environment variable to import, otherwise the import will be abnormal9  fromLib.mainImportServerTenServer.run (port = 8080,host ='0.0.0.0', debug = True)#The default port number is One #host = ' 0.0.0.0 ' means that everyone in the LAN can access their interfaces via IP

5, setting set general variables, etc.

1 ' x.x.x.x ' 2 ' 123456 ' 3 PORT = 33064'jxz'5'jxz  '

6. main.py ... Own main program

7. Tools tool class files, related functions in this area
