如何在烧瓶中验证WTFFORMS中的两个validate_fields

from flask import Flask, request
from wtforms import Form, StringField, validators

app = Flask(__name__)

class MyForm(Form):
    field1 = StringField('Field 1', validators=[validators.DataRequired()])
    field2 = StringField('Field 2', validators=[validators.Length(min=3, max=10)])

@app.route('/validate', methods=['POST'])
def validate():
    form = MyForm(request.form)
    if form.validate():
        return 'Validation successful'
    else:
        return 'Validation failed'

if __name__ == '__main__':
    app.run()
