Question

我想要获取参数格式def：a（）到def：b（）的值并返回到html文件。如何在python烧瓶的不同路径中将def的值传递给def？

@app.route('/a',methods=['GET','POST'])
def a():
    if request.method == 'POST':
       text_a = request.form.get('text')
    return render_template('index.html')

AND

@app.route('/b',methods=['GET','POST'])
def b():
    if request.method == 'POST':
       return render_template('index.html',text = text_a )
    return render_template('index.html' )

PS>路径/ a中的我想输入文本并提交，然后将/ a的值获取到/ b

HTML文件

 <form method="POST" action= "/a" >
  <input type="text" name="text">
<input class="btn btn-primary" type="submit"  value="submit">
 </form>

 {{text}}

谢谢您的帮助。

您可以使用Flask sessions存储从一个请求到下一个请求的信息。

@app.route('/a',methods=['GET','POST'])
def a():
    if request.method == 'POST':
       session['text_a'] = request.form.get('text')
    return render_template('index.html')

@app.route('/b',methods=['GET','POST'])
def b():
    if request.method == 'POST':
       return render_template('index.html',text=session['text_a'] )
    return render_template('index.html' )
