Question

我正在使用Flask和Flask-Mail构建一个简单的联系页面。我按照本教程构建了应用程序 - Add a contact page - 现在当我尝试发送消息时，我收到了错误gaierror: [Errno -2] Name or service not known。我一直在谷歌搜索错误一段时间，并没有在线找到任何类似的例子。我甚至无法弄清楚它找不到的名称或服务。

回溯页面将让我展开一行并执行一些Python代码。它提供了一个dump()函数，它将向我显示所有变量，并且可以在对象上调用它们以查看它们的信息（如果这有用）。

routes.py：

from forms import ContactForm
from flask.ext.mail import Message, Mail


mail = Mail()
app = Flask(__name__)


app.secret_key = 'development key'

app.config['MAIL_SERVER'] = 'smtp.google.com'
app.config['MAIL_PORT'] = 465
app.config['MAIL_USE_SSL'] = True
app.config['MAIL_USERNAME'] = 'email'
app.config['MAIL_PASSWORD'] = 'password'

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

    if request.method == 'POST':
        if not form.validate():

形式：

from flask.ext.wtf import Form, validators
from wtforms.fields import TextField, TextAreaField, SubmitField
import wtforms


class ContactForm(Form):
    name = TextField("Name", [wtforms.validators.Required('Please enter your name')])
    email = TextField("Email", [wtforms.validators.Required('Please enter your email'), wtforms.validators.Email()])
    subject = TextField("Subject", [wtforms.validators.Required('Please enter a subject')])
    message = TextAreaField("Message", [wtforms.validators.Required('Please enter a message')])
    submit = SubmitField("Send")
            flash('All fields are required.')
            return render_template('contact.html', form=form)
        else:
            msg = Message(form.subject.data, sender='imauld@gmail.com', recipients=['imauld@gmail.com'])
            msg.body = """From: %s &lt;%s&gt; %s""" % (form.name.data, form.email.data, form.message.data)
            mail.send(msg)
            return render_template('contact.html', success=True)
    elif request.method == 'GET':
        return render_template('contact.html', form=form)

Answer 1

我有以下适用于我的设置

app.config['MAIL_SERVER']='smtp.gmail.com'
app.config['MAIL_PORT'] = 465
app.config['MAIL_USERNAME'] = 'xx@gmail.com'
app.config['MAIL_PASSWORD'] = 'xx;'
app.config['MAIL_USE_TLS'] = False
app.config['MAIL_USE_SSL'] = True

请注意我拥有的MAIL_USE_TLS参数。还不确定它是否重要但是你的MAIL_SERVER设置为smtp.google.com而我的是smtp.gmail.com。

编辑：已确认，主要问题是您的smtp主机设置不正确。它应始终为smtp.gmail.com

使用Flask-Mail通过Gmail-socket.gaierr发送电子邮件
