用户发送请求,返回帐号和密码
###利用框架flask
整体思路:
导包
...
给模版传递消息 用flash --需要对内容加密,因此需要设置 secret_key , 做加密消息的混淆
app = Flask(__name__) app.secret_key = 'kingdomai'
使用wtf实现表单,需要自定义一个表单类
#validators=[DataRequired()保证填写了内容 class LoginForm(FlaskForm): username = StringField('用户名:', validators=[DataRequired()]) submit = SubmitField('提交')
设置游标,并且方法为get和post
@app.route('/form', methods=['GET', 'POST'])
定义一个方法
def login(): login_form = LoginForm()
c判断请求方式
if request.method == 'POST':
获取请求参数
username = request.form.get('username')
验证参数,wtf一句话实现校验,没有CSRF token将报错,在表单中添加{{ form.csrf_token }}
if login_form.validate_on_submit():
执行shell
username = username print('创建用户...') # 创建用户 os.system('useradd %(name)s -s /home/work/%(name)s' % {'name': username}) # 随机一个密码 password = str((random.randint(100000, 999999))) # 设置密码 os.system('echo %(name)s:%(pwd)s |chpasswd' % {'name': username, 'pwd': password}) # 将面试题放入新创建用户路径下 os.system('cp -r /home/renligeng/exam/ /home/work/%(name)s' % {'name': username}) # 设置该路径权限 os.system('chmod 700 /home/work/%(name)s' % {'name': username}) # 设置用户权限 os.system('setfacl -m u:%(name)s:rwx /home/work/%(name)s' % {'name': username}) # 输出 os.system('echo "您好,您的账号为:" %(name)s ",密码为:" %(pwd)s' % {'name': username, 'pwd': password}) return ('您好,您的账号为:' + username + ',密码为:' + password)

index.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form method="post"> {{ form.csrf_token }} {{ form.username.label }}{{ form.username }}<br> {{ form.submit }}<br> {% for message in get_flashed_messages() %} {{message}} {% endfor %} <hr> </form> </body> </html>
