auth.py中源码：
auth_bp = Blueprint('auth', __name__, subdomain='auth')
@auth_bp.route('/login', methods=['GET', 'POST'], subdomain='auth')
def login():
if current_user.is_authenticated:
return redirect(url_for('blog.index'))
form = LoginForm()
if form.validate_on_submit():
username = form.username.data
password = form.password.data
remember = form.remember.data
admin = Admin.query.first()
if admin:
if username == admin.username and admin.validate_password(password):
login_user(admin, remember)
flash('Welcome back.', 'info')
return redirect_back()
flash('Invalid username or password.', 'warning')
else:
flash('No account.', 'warning')
return render_template('auth/login.html', form=form)
@auth_bp.route('/logout', subdomain='auth')
@login_required
def logout():
logout_user()
flash('Logout success.', 'info')
return redirect_back()
init.py源码：
def register_blueprints(app): # 注册蓝本
app.register_blueprint(blog_bp) # 注册蓝本
app.register_blueprint(admin_bp, url_prefix='/admin') # 注册蓝本
# app.register_blueprint(auth_bp, url_prefix='/auth')
app.register_blueprint(auth_bp, subdomain='auth')
模板中源码：
{% if current_user.is_authenticated %}
<a href="{{ url_for('auth.logout', next=request.full_path)}}">Logout</a>
{% else %}
<a href="{{ url_for('auth.login', next=request.full_path) }}">Login</a>
{% endif %}
但点击后显示网页找不到，请问该如何改正？
