搭建指南

任何问题请在Discussions中提问

1. 建立数据库

   MySQL design

   Three tables

   Name	explanation
   student	student information
   teacher	teacher information
   leave	leave history

   Table - student

   name	explanation	type-length
   student_id(pri key)	id	decimal-65
   name	name	varchar-255
   s_class	class	varchar-255
   passwd	password	varchar-255
   room	dormitory	varchar-255

   Table - teacher

   name	explanation	type-length
   teacher_id(pri key)	id	decimal-65
   name	name	varchar-255
   passwd	password	varchar-255
   role	0 is staff, 1 is faculty	int-2

   Table - leave

   name	explanation	type-length
   leave_num(pri key)	unique index	decimal-65
   student_id	reference on student(student_id)	decimal-65
   start_time	start time	datetime-0
   end_time	end time	datetime-0
   reason	reason	varchar-255
   flag	status (0 is decline, 1 is waiting, 2 is approved)	int-2
   type	type（1 is absence, 2 is sickness,3 is others）	int-2
   teacher1_id	stuff's id	decimal-65
   teacher2_id	faculty's id	decimal-26
   ensure	route of picture	varchar-255

2. 安装依赖

• flask

• sqlalchemy

• flask_sqlalchemy

• werkzeug.security

启动后端服务

在RESTful_backend.py 32和368行配置数据库

python RESTful_backend.py

API

URL	explanation
/login	post ('userId', 'userPwd'); return (flag etc)
/student/ask_leave	post ('leave_num','student_id','start_time','end_time','reason','flag','teacher1_id','teacher2_id','type','ensure'); return (True \ False)
/student/search_leave	post ('student_id'), return ('leave_num','student_id','start_time','end_time','reason','flag','teacher1_id','teacher2_id','type','ensure')
/student/search_leave_detail	post('student_id'), return ('student_id','class','name','room')
/teacher/search_leave	post('teacher_id'), return('leave_num','student_id','start_time','end_time','reason','flag','teacher1_id','teacher2_id','type','ensure')
/teacher/update_leave	post('leave_num','flag'); return (True / False)
/teacher2/search_leave	post('teacher_id'), return ('leave_num','student_id','start_time','end_time','reason','flag','teacher1_id','teacher2_id','type','ensure')
/teacher/search_id	post('school'), return ('teacher_id','name','role')
/pwd	post('userId','userPwd') return (True / False)
/name	post('name'), return ('leave_num','student_id','start_time','end_time','reason','flag','teacher1_id','teacher2_id','type','ensure','class','school','room')
