我已经通过多个帖子对此问题进行了很多研究,并且无论我尝试什么,我都会遇到问题。从本质上讲,我正在尝试在输入字段中写一些东西,按下提交按钮,然后从输入字段中发布字符串,并在使用flask时将其显示在单独的页面/单独的路径上。我认为下面的内容是正确的,但是它返回的值是None,而不是我在index.html的输入字段中写的值。
from flask import Flask, render_template, request, jsonify, Response,
redirect, url_for,session
from flask_bootstrap import Bootstrap
app = Flask(__name__)
Bootstrap(app)
app.secret_key = 'dljsaklqk24e21cjn!Ew@@dsa5'
@app.route('/', methods=['GET', 'POST'])
def hello():
if request.method == 'POST':
nme = request.form['name']
session['name'] = nme
return url_for(deliver)
return render_template('index.html')
@app.route('/delivery', methods=['GET', 'POST'])
def deliver():
name = session.get('name')
return render_template('delivery.html', name=name)
index.html是
<form action = "{{ url_for('deliver')}}" method = "POST">
<p>Name <input type = text class="form-control" name = "name" /></p>
<p>Address <input type = text class="form-control" name = "Address" /></p>
<input type=submit name='submit'>
</form>
and delivery.html是
<div class="card-deck mx-auto" style="width: 75rem;">
<div class="card text-white bg-dark p-3" style="width: 45rem;">
<h5 class="card-title text-center"></h5>
<img class="card-img-top mx-auto" src="/static/img/hands.png" alt="Vibration
Image" style="width:20%">
<div class="card-body">
<h2 class="card-title text-center">Delivery Information</h2>
<h5> {{name}} </h5>
答案 0 :(得分:1)
此代码:
binaries
表示提交表单将过帐到<form action = "{{ url_for('deliver')}}" method = "POST">
,但是您确实要过帐到索引页面以触发/deliver
代码。因此,只需删除操作即可。
您还需要更改
session['name'] = nme
到
return url_for(deliver)
