python编写OA办公

Python编写OA办公系统实现指南

引言

本文将介绍如何使用Python编写一个简单的OA办公系统。OA办公系统是一种通过电子化手段管理和处理办公室日常事务的系统，可以提高工作效率和信息共享。对于刚入行的小白开发者，本文将提供一个实现该系统的详细步骤，并提供相应代码和注释。

OA办公系统实现步骤

下表展示了实现OA办公系统的主要步骤和相应代码。

步骤	描述	代码
1	创建数据库	CREATE DATABASE oadb;
2	创建用户表	CREATE TABLE users (id INT PRIMARY KEY AUTO_INCREMENT, name VARCHAR(50), email VARCHAR(50), password VARCHAR(50));
3	创建部门表	CREATE TABLE departments (id INT PRIMARY KEY AUTO_INCREMENT, name VARCHAR(50));
4	创建任务表	CREATE TABLE tasks (id INT PRIMARY KEY AUTO_INCREMENT, title VARCHAR(100), description TEXT, assignee_id INT, department_id INT, FOREIGN KEY (assignee_id) REFERENCES users(id), FOREIGN KEY (department_id) REFERENCES departments(id));
5	实现用户注册功能	```python

from flask import Flask, request, jsonify import mysql.connector

app = Flask(name)

@app.route('/register', methods=['POST']) def register(): data = request.get_json() name = data['name'] email = data['email'] password = data['password']

# 连接数据库
cnx = mysql.connector.connect(user='root', password='yourpassword', host='localhost', database='oadb')
cursor = cnx.cursor()

# 插入用户数据
query = "INSERT INTO users (name, email, password) VALUES (%s, %s, %s)"
values = (name, email, password)
cursor.execute(query, values)
cnx.commit()

# 关闭数据库连接
cursor.close()
cnx.close()

return jsonify({'message': 'User registered successfully'})

| 6 | 实现用户登录功能 | ```python
@app.route('/login', methods=['POST'])
def login():
    data = request.get_json()
    email = data['email']
    password = data['password']
    
    # 连接数据库
    cnx = mysql.connector.connect(user='root', password='yourpassword', host='localhost', database='oadb')
    cursor = cnx.cursor()
    
    # 查询用户数据
    query = "SELECT * FROM users WHERE email = %s AND password = %s"
    values = (email, password)
    cursor.execute(query, values)
    user = cursor.fetchone()
    
    # 关闭数据库连接
    cursor.close()
    cnx.close()
    
    if user:
        return jsonify({'message': 'User logged in successfully'})
    else:
        return jsonify({'message': 'Invalid email or password'})
``` |
| 7 | 实现部门创建功能 | ```python
@app.route('/departments', methods=['POST'])
def create_department():
    data = request.get_json()
    name = data['name']
    
    # 连接数据库
    cnx = mysql.connector.connect(user='root', password='yourpassword', host='localhost', database='oadb')
    cursor = cnx.cursor()
    
    # 插入部门数据
    query = "INSERT INTO departments (name) VALUES (%s)"
    values = (name,)
    cursor.execute(query, values)
    cnx.commit()
    
    # 关闭数据库连接
    cursor.close()
    cnx.close()
    
    return jsonify({'message': 'Department created successfully'})
``` |
| 8 | 实现任务创建功能 | ```python
@app.route('/tasks', methods=['POST'])
def create_task():
    data = request.get_json()
    title = data['title']
    description = data['description']
    assignee_id = data['assignee_id']
    department_id = data['department_id']
    
    # 连接数据库
    cnx = mysql.connector.connect(user='root', password='yourpassword', host='localhost', database='oadb')
    cursor = cnx.cursor()
    
    # 插入任务数据
    query = "INSERT INTO tasks (title, description, assignee_id, department_id) VALUES (%s, %s, %s, %s)"
    values = (title, description, assignee_id, department_id)
    cursor.execute(query, values)
    cnx.commit()
    
    # 关闭数据库连接
    cursor.close()
    cnx.close()
    
    return jsonify({'message': 'Task created successfully'})
