完成个人中心 导航标签

1. 个人中心—视图函数带标签页面参数tag
   @app.route('/usercenter/<user_id>/<tag>')
   def usercenter(user_id, tag):
      if tag == ‘1':
          return render_template('usercenter1.html', **context)
   
   
2. 个人中心—导航标签链接增加tag参数
   <li role=“presentation”><a href=“{{ url_for(‘usercenter’,user_id = user.id,tag = ‘1’) }}">全部问答</a></li>
3. 个人中心—有链接到个人中心页面的url增加tag参数
   u <a href="{{ url_for('usercenter',user_id = session.get('userid'), tag=1) }}">{{ session.get('user') }}</a>
