您在表单中添加了两个按钮，因此请检查哪个字段的数据是True。
from flask import Flask, render_template, redirect, url_for
from flask_wtf import Form
from wtforms import SubmitField
app = Flask(__name__)
app.secret_key = 'davidism'
class StatsForm(Form):
user_stats = SubmitField()
room_stats = SubmitField()
@app.route('/stats', methods=['GET', 'POST'])
def stats():
form = StatsForm()
if form.validate_on_submit():
if form.user_stats.data:
return redirect(url_for('user_stats'))
elif form.room_stats.data:
return redirect(url_for('room_stats'))
return render_template('stats.html', form=form)
app.run(debug=True)
<form method="post">
{{ form.hidden_tag() }}
{{ form.user_stats }}
{{ form.room_stats }}
</form>
