问题描述
我在Flask应用程序中使用flask_form,现在已经因为"CSRF令牌不匹配"而停留了几个小时.
I'm using flask_form in my Flask application and have being stucked for hours now with the 'CSRF Token do not match'.
<form method="post" action="{{ url_for('auth.login') }}" role="form">
{{ form.hidden_tag() }}
{{ wtf.form_errors(form, hiddens="only") }}
{{ wtf.form_field(form.email)}}
{{ wtf.form_field(form.password)}}
<p><button type="submit">Login</button></p>
</form>
views.py
@auth.route('/login', methods=['GET', 'POST'])
def login():
form = LoginForm()
if form.validate_on_submit():
print('login form received on server and is valid')
# check whether user exists in the database and whether
# the password entered matches the password in the database
user = User.query.filter_by(email=form.email.data).first()
if user is not None and user.verify_password(form.password.data) and check_password_hash(user.pwd, form.password.data):
# log employee in
login_user(user) #,remember=True)
# redirect to the home page after login
return redirect(url_for('grapher.upload'))
# when login details are incorrect
else:
flash('Invalid email or password.', 'info')
# load login template
return render_template('auth/login.html', form=form, title='Login')
表格
class LoginForm(FlaskForm):
email = StringField('Email', validators=[DataRequired(), Email(), Length(min=1,max=254, message='The maximum length of this filed is 254 characters')])
password = PasswordField('Password', validators=[DataRequired(), Length(max=20, message='Password maximium length is 20 characters.')])
为什么会出现此错误?
