我正在使用Flask和Flask-Mail构建一个简单的联系页面.我按照本教程建立了应用程序 –
Add a contact page – 现在当我尝试发送消息时,我收到了错误gaierror:[Errno -2]名称或服务未知.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(如果这将有所帮助).
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():
表格:
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)

解决方法
我有以下设置适合我
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.它应该始终是smtp.gmail.com
