Python 如何为其他app.routes引用Flask中的变量

我是一名学生，正在学习如何使用flask，并计划将其与Matplotlib（graph maker库）集成。我已经从用户那里得到了输入，并将它们存储为变量。但是，在以后的代码中不能调用这些变量

这是我的烧瓶代码：

 @app.route('/', methods = ['POST','GET'])
def upload_file():
    global title, x_axis, y_axis
    if request.method == 'POST':
        f = request.files['file']
        if True == allowed_file(f.filename):
            f.save(f.filename)
            print(f)

    if request.method == 'POST':
        if request.method == 'POST':
            reqform = request.form
            #
            title = reqform['title']
            x_axis = reqform['x_axis']
            y_axis = reqform['y_axis']
            #
            print(title, x_axis, y_axis)

    return render_template('uploaded.html') #, title = title, form = reqform, f = f.filename )

我想在另一个@app.route中调用变量，如

title

，

x\u轴

，

y\u轴

，以生成一个图形

我不确定我是否足够具体，但是，任何帮助都将不胜感激。谢谢

在路由器之间存储和访问数据有几种方法。实现这一点的一种方法是使用烧瓶：

 @app.route('/', methods = ['POST','GET'])
def upload_file():
    global title, x_axis, y_axis
    if request.method == 'POST':
        f = request.files['file']
        if True == allowed_file(f.filename):
            f.save(f.filename)
            print(f)

    if request.method == 'POST':
        if request.method == 'POST':
            reqform = request.form
            # assign in session variable

            session['title'] = reqform['title']
            session['x_axis'] = reqform['x_axis']
            session['y_axis'] = reqform['y_axis']

    return render_template('uploaded.html')

@app.route('/another_endpoint', methods = ['POST','GET'])
    def another_endpoint():
       title = session.get('title', None)
       x_axis = session.get('x_axis', None)
       y_axis = session.get('y_axis', None)
       # do something...
