   @app.route('/usercenter/<user_id>/<tag>')
   @loginFirst
   def usercenter(user_id,tag):
       user=User.query.filter(User.id==user_id).first()
       context={
           'user':user,
           'question':user.question,
           'comments':user.comments

       if tag == '1':
           return render_template('usercenter1.html', **context)
       elif tag == '2':
           return render_template('usercenter2.html', **context)

         <a class="nav-link"  href="{{ url_for('usercenter1',user_id=user.id,tag=1)}}">全部问题</a>
       </li>
