User sends request, returns account and password
### Utilize the framework flask
Overall Thoughts:
- # Purpose: Implement simple login logic
- # 1 Need get and post request methods Need to determine request method
- # 2 Getting Parameters
- # 3 Execute the shell
- # 4 If the judgment is all right, return the result

Delivering messages to templates with flash - need to encrypt the content, so you need to set the secret_key , to do the obfuscation of the encrypted messages
app = Flask(__name__) app.secret_key = 'kingdomai'
Implementing a form using wtf requires customizing a form class
#validators=[DataRequired() guarantees that the content is filled out
class LoginForm(FlaskForm):
username = StringField('Username:', validators=[DataRequired()])
submit = SubmitField('Submit')
Set the cursor and the methods get and post.
@('/form', methods=['GET', 'POST'])
Define a method
def login(): login_form = LoginForm()
cJudging the way the request is made
if == 'POST':
Get request parameters
username = ('username')
Validation parameters, wtf a sentence to achieve the checksum, no CSRF token will report an error, add {{ form.csrf_token }} in the form
if login_form.validate_on_submit():
Execute the shell
username = username
print('Create user...')
# Create users
('useradd %(name)s -s /home/work/%(name)s' % {'name': username})
# Randomize a password
password = str(((100000, 999999)))
# Set the password
('echo %(name)s:%(pwd)s |chpasswd' % {'name': username, 'pwd': password})
# Put interview questions under newly created user paths
('cp -r /home/renligeng/exam/ /home/work/%(name)s' % {'name': username})
# Set permissions for the path
('chmod 700 /home/work/%(name)s' % {'name': username})
# Setting user privileges
('setfacl -m u:%(name)s:rwx /home/work/%(name)s' % {'name': username})
# Output
('echo "Hello, your account number is:" %(name)s ",Password:" %(pwd)s' % {'name': username, 'pwd': password})
return ('Hello, your account number is:' + username + ',Password:' + password)
