发送电子邮件 flask google 应用程序引擎 - 发件人格式无效

Question

我正在尝试在 google 应用引擎上制作一个简单的 Flask 联系表。我对两者都是新手。

我使用了两个链接来帮助我： https://cloud.google.com/appengine/docs/python/mail/sendingmail http://www.boxcontrol.net/adding-contact-form-to-your-site-using-flask-and-python3.html#.VWnRUlzBzGc

这是我的代码：

main.py

from flask import Flask, render_template, request
from google.appengine.api import mail
from forms import ContactForm


app = Flask(__name__)
app.secret_key = 'YourSuperSecreteKey'


@app.route('/')
def hello():
    """Return a friendly HTTP greeting."""
    return 'Hello World!'


@app.route('/contact', methods=('GET', 'POST'))
def contact():
    form = ContactForm()

    if request.method == 'POST':
        if form.validate() == False:
            return 'Please fill in all fields <p><a href="/contact">Try Again!!!</a></p>'
        else:
            message = mail.EmailMessage(sender=form.name.data,
                            subject="Contact")
            message.to = form.email.data
            message.body = form.message.data
            message.send()
            return "Successfully  sent message!"
        elif request.method == 'GET':
        return render_template('contact.html', form=form)

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

form.py

from flask_wtf import Form
from wtforms import StringField, TextAreaField, SubmitField, validators

def CheckNameLength(form, field):
  if len(field.data) < 4:
    raise ValidationError('Name must have more then 3 characters')

class ContactForm(Form):
    name = StringField('Your Name:', [validators.DataRequired(), CheckNameLength])
    email = StringField('Your e-mail address:', [validators.DataRequired(), validators.Email('your@email.com')])
    message = TextAreaField('Your message:', [validators.DataRequired()])
    submit = SubmitField('Send Message')

我得到的错误是：抱歉，意外错误：发件人格式无效

任何人都可以帮助我理解我做错了什么吗？

您是否遵守他们关于谁可以出现在电子邮件发件人字段中的规则？

The email address of the sender, the From address. The sender address must be one of the following types:

The address of a registered administrator for the application. You can add administrators to an application using the Administration Console.

The address of the user for the current request signed in with a Google Account. You can determine the current user's email address with the Users API. The user's account must be a Gmail account, or be on a domain managed by Google Apps.

Any valid email receiving address for the app (such as xxx@APP-ID.appspotmail.com).

Any valid email receiving address of a domain account, such as support@example.com. Domain accounts are accounts outside of the Google domain with email addresses that do not end in @gmail.com or @APP-ID.appspotmail.com.
