问题
I would like to be able to write a multi-line text in a textarea (HTML), and retrieve this text in python for processing using Flask. Alternatively, I would like to be able to write a multi-line text in a form. I have no clue on using JS, so that won't help me. How am I to go about doing that?
回答1:
Render a template with the form and textarea. Use url_for to point the form at the view that will handle the data. Access the data from request.form.
templates/form.html:
<form action="{{ url_for('submit') }}" method="post">
<textarea name="text"></textarea>
<input type="submit">
</form>
app.py:
from flask import Flask, request, render_template
app = Flask(__name__)
@app.route('/')
def index():
return render_template('form.html')
@app.route('/submit', methods=['POST'])
def submit():
return 'You entered: {}'.format(request.form['text'])
