Python Flask：如何在html页面和应用程序路径之间传递变量

我有一个getvlanconfig.html页面，其中包含一个表单，用于收集vlanid和VLANetwork等信息。我希望能够将该信息传递到提交表单时加载的页面showvlanconfig.html。 我对烧瓶是新手，无论我做什么查找，我都无法找到最好的方法。我也看了一些会议，我不确定这是否是我的选择

    from flask import Flask, render_template, url_for, flash, request, redirect


    app = Flask(__name__)

    @app.route('/')
    def homepage():
      return render_template("index.html")

    @app.route('/getvlanconfig/', methods=["GET","POST"])
    def getvlan():

      try:

          if request.method == "POST":
             getvlanid = request.form['vlanid']
             getvlannetwork = request.form['vlannetwork']

             return redirect(url_for('showvlan'))
      except Exception as e:

             return render_template("vlanconfig.html")


 @app.route('/showvlanconfig', methods=["GET","POST"])
 def showvlan():
      try:          
         getvlanid = ???
         getvlannetwork = ?? 
         return render_template("index.html", vlanid = getvlanid, vlannetwork = getvlannetwork)
      except Exception as e:
         flash(e)


if __name__ == "__main__":
  app.run(debug = True)

使用会话在来自同一客户端的请求之间存储数据

from flask import session

def getvlan():
    session['vlanid'] = request.form['vlanid']
    return redirect(url_for('showvlan'))

def showvlan():
    vlanid = session['vlanid']
    ...

使用数据库（或其他外部持久存储）以更普遍的可访问方式存储数据。
