Question

下面是我的代码，我试图让装饰器验证所需的flask角色，但似乎不起作用。我不确定自己做错了什么。我尝试了几种不同的方法，但似乎都没有效果。

有人可以使用基于角色的访问控制的经验或模板吗？

app= Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://root:admin@localhost/sys' 
app.config['SECRET_KEY'] = 'mysecret'

db = SQLAlchemy(app)
login = LoginManager(app)
login.init_app(app)
login.login_view = 'login'
LOGIN_URL='/login'
@login.user_loader
def load_user(user_id):
        return Users.query.get(user_id)

class Users(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(20))
    password = db.Column(db.String(200))
    roles = db.Column(db.String(100))
    def is_authenticated(self):
        return True
    def is_active(self):
        return True
    def has_roles(self):
        return True    

@app.route('/vendorreview')
@login_required
@roles_required('admin')
def vendorreview():
    return render_template('review.html')
@app.route('/register')
@login_required
def register():  
    return render_template('register.html')
@app.route('/submit')
def submit():
    if not session.get('logged_in'):
        return render_template('login.html')
    else:
        return render_template('submit.html')
    return render_template('submit.html')
@app.route('/error')
def error():
    return render_template('error.html')

@app.route("/login", methods=['GET', 'POST'])
def login():
    error = None
    x='customer'
    if request.method == 'POST':
        if request.form['username'] == 'admin' and request.form['password'] == 'admin' and x == 'business':
            session['logged_in'] = True
#            get_role = 'admin'
            return redirect(url_for('index'))    
        #for customers
        elif request.form['username'] == 'admin' and request.form['password'] == 'admin' and x == 'customer':
            session['logged_in'] = True
            return redirect(url_for('index'))    
        else:
            error = 'Invalid Credentials. Please try again.'
    return render_template('login.html', error=error)


if __name__ == '__main__':
    app.secret_key = os.urandom(12)
    app.run(debug=True)

所需的烧瓶角色不起作用
