我决定按照本教程（https://www.boxcontrol.net/adding-contact-form-to-your-site-using-flask-and-python3.html）创建不同类型的表单，用户输入其个人信息并将提交的表单通过电子邮件发送给我的G-mail帐户。然而，在提交表格后，我收不到电子邮件或错误。
我做的第一件事就是创建ContactForm类。用户提交表单时不发送电子邮件的Flask-WTF表单
from flask_wtf import Form
from wtforms import TextField, TextAreaField, SubmitField
from wtforms.validators import InputRequired
class ContactForm(Form):
name = TextField("Fullname", validators=[InputRequired('Please enter your name.')])
email = TextField("Email", validators=[InputRequired("Please enter your email address.")])
NoChildren = TextField("Number of children dependants (if applicable):", validators=[InputRequired("Please enter a subject.")])
NoAdults = TextField("Number of adult dependants (if applicable):", validators=[InputRequired("Please enter a subject.")])
travel = TextField("Will you be travelling alone?", validators=[InputRequired("Please enter a subject.")])
marriage = TextField("What is your marital status?", validators=[InputRequired("Please enter a subject.")])
nation = TextField("Current nationality(ies):", validators=[InputRequired("Please enter a subject.")])
dob = TextField("Date of birth:", validators=[InputRequired("Please enter a subject.")])
phone = TextField("Phone number:", validators=[InputRequired("Please enter a subject.")])
nonukaddress = TextField("Your current non-UK address:", validators=[InputRequired("Please enter a subject.")])
ukaddress = TextField("UK address:", validators=[InputRequired("Please enter a subject.")])
history = TextField("Do you have any criminal history?", validators=[InputRequired("Please enter a subject.")])
hadvisa = TextField("Have you ever had any other visas?", validators=[InputRequired("Please enter a subject.")])
refusevisa = TextField("Have you been refused a visa before?", validators=[InputRequired("Please enter a subject.")])
medical = TextField("Did you receive any medical treatment in the UK?", validators=[InputRequired("Please enter a subject.")])
letter = TextField("Do you have a letter from a UK regulated financial institution confirming that original evidence of funds has been supplied?", validators=[InputRequired("Please enter a subject.")])
sole = TextField("Are you the sole owner of the money?", validators=[InputRequired("Please enter a subject.")])
additional = TextAreaField("Additional information/questions/requests:", validators=[InputRequired("Please enter a message.")])
submit = SubmitField("Send")
然后我为我的表单创建了HTML模板。
{% block content %}
<h2>Contact</h2>
{% if success %}
<p>Thank you for your message. We'll get back to you shortly.</p>
{% else %}
{% for message in form.name.errors %}
<div class="flash">{{ message }}</div>
{% endfor %}
{% for message in form.email.errors %}
<div class="flash">{{ message }}</div>
{% endfor %}
<form action="{{ url_for('contact') }}" method=post>
{{ form.hidden_tag() }}
{{ form.name.label }}
{{ form.name }}
{{ form.email.label }}
{{ form.email }}
{{ form.NoChildren.label }}
{{ form.NoChildren }}
{{ form.travel.label }}
{{ form.travel }}
{{ form.marriage.label }}
{{ form.marriage }}
{{ form.nation.label }}
{{ form.nation }}
{{ form.dob.label }}
{{ form.dob }}
{{ form.phone.label }}
{{ form.phone }}
{{ form.nonukaddress.label }}
{{ form.nonukaddress }}
{{ form.ukaddress.label }}
{{ form.ukaddress }}
{{ form.history.label }}
{{ form.history }}
{{ form.hadvisa.label }}
{{ form.hadvisa }}
{{ form.refusevisa.label }}
{{ form.refusevisa }}
{{ form.parents.label }}
{{ form.parents }}
{{ form.medical.label }}
{{ form.medical }}
{{ form.letter.label }}
{{ form.letter }}
{{ form.sole.label }}
{{ form.sole }}
{{ form.ukbank.label }}
{{ form.ukbank }}
{{ form.additional.label }}
{{ form.additional }}
{{ form.submit }}
</form>
{% endif %}
{% endblock %}
我的主烧瓶文件看起来像这样。
