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，收到错误消息 gaierror: [Errno -2] Name or service not known。我已经在谷歌上搜索了一段时间的错误，但在网上找不到任何类似的例子。我什至不知道它找不到什么名称或服务。
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，可以向我显示所有变量，并且可以在对象上调用以查看它们的信息(如果有帮助的话)。
路线.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 <%s> %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)

最佳答案
我有以下适合我的设置
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。也不确定它是否重要，但您的 MAIL_SERVER 设置为 smtp.google.com 而我的是 smtp.gmail.com。
编辑:经确认，主要问题是您的 smtp 主机设置不正确。它应该始终是 smtp.gmail.com
