我在我的Flask應用程序中使用了flask_form,並且因'CSRF令牌不匹配'而被暫停了幾個小時。Flask_form:CSRF令牌不匹配
<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')
形式
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.')])
爲什麼我得到這個錯誤?
請發佈您的全部錯誤信息 – Nabin
請將您的錯誤和代碼初始化令牌 –
我得到的唯一錯誤消息是我的窗體下的「CSRF令牌不匹配」。我怎麼能得到更相關的錯誤信息? 我沒有使用CSRF擴展,只是wtf_form(根據文檔:「任何使用FlaskForm處理請求的視圖已經獲得CSRF保護」) – user7924113
