摘要:
本文基于python的图书馆管理系统和读者系统,实现了登录、注册、忘记密码、书籍查询、借阅、归还、修改等功能,通过csv文件将数据存储在本地。注册时采用了邮箱验证码,模拟了现实场景。(全部源代码地址见文末)如果有其他奇思妙想或者bug欢迎提出来!

功能介绍:
1、登录
会判断账号是否存在和输入是否正确,密码错误可以进行忘记密码操作。
# 登录(记录操作者)
def Sign_in(x): #管理员账号表或读者账号表,0管理员,1读者
global administrators
global user
#判断学号密码是否正确
#学号必须是数字
while True:
try:
id = int(input('请输入学号:'))
break
except:
print('学号必须是数字!')
password = input('请输入密码:')
#查询学号是否存在,密码是否正确
if x==0:
sign_in_data = administrators
elif x==1:
sign_in_data = user
#print(sign_in_data)
while (id not in sign_in_data['学号'].values)or(sign_in_data[sign_in_data['学号']==id]['密码'].values[0] != password):
print('账号或密码输入错误!\n')
print('\n* * * * * * * * 请 选 择 所 需 功 能 * * * * * * * * \n\n\t\t 1.重新尝试\n\t\t 2.忘记密码\n\t\t 3.退回首页\n\n* * * * * * * * * * * * * * * * * * * * * * * * * *\n')
pick = Pick(3)
if pick == 1:
return 11
elif pick == 2: #忘记密码操作
email = (sign_in_data.loc[sign_in_data['学号']==id]['邮箱'].values[0])
if email != 0: #账号存在
if x == 0:
return forget(email[0],0)
elif x==1:
return forget(email[0],1)
else:
print('账号不存在!')
return 0
elif pick == 3:
return 0
print("正在登录.......")
time.sleep(3)
print('登录成功!')
return id
2、注册
会判断账号是否存在,账号、密码格式是否正确,会向所填邮箱发送验证码,并将注册后的账号密码等信息记录起来。(QQ和QQ授权码需要换成自己的 )
发送验证码
#发验证码
def to_email(email,txt):
# 发信方的信息:发信邮箱,QQ 邮箱授权码
from_addr = '自己的@qq.com'
password = '自己的邮箱授权码'
# 发信服务器
smtp_server = 'smtp.qq.com'
msg = MIMEMultipart()
msg['From'] = formataddr(["图书馆管理系统",from_addr])
msg['To'] = formataddr(['',email])
msg['Subject'] = Header('图书馆管理系统-邮箱验证')
# 邮箱正文内容,第一个参数为内容,第二个参数为格式(plain 为纯文本),第三个参数为编码
#生成一个随机验证码
if txt == 0:
code = ''.join(random.choice(string.ascii_letters + string.digits) for _ in range(5))
txt='【图书馆管理系统】本次验证码为'+code+',您正在申请通过图书馆管理系统验证,如非本人操作,请忽略。'
msg.attach(MIMEText(txt, 'plain', 'utf-8'))
server = smtplib.SMTP_SSL(smtp_server)
server.connect(smtp_server,465)
server.login(from_addr, password)
server.sendmail(from_addr, email, msg.as_string())
# 关闭服务器
server.quit()
print(f'验证码已发送至{email},请注意查收!')
return code
密码格式判断
# 密码格式判断
def count(s):
num, char, space, d ,count= 0, 0, 0, 0 ,0 # 分别统计数字、字母、空格、其他字符个数
for i in s:
if i.isdigit():
num += 1
elif i.isalpha():
char += 1
elif i == ' ':
space += 1
print('密码存在空格!')
return 0
else:
d += 1
for i in [num, char, d]:

count += 1
if count>=2:
return 1
else:
