Socket.error: [Errno 111] Connection refused when submitting an email using flask-mail

Question

from flask_mail import Mail, Message
app = Flask(__name__)
mail = Mail(app)
app.config.update(
    #EMAIL SETTINGS
    MAIL_SERVER='smtp.gmail.com',
    MAIL_PORT=465,
    MAIL_USE_SSL=True,
    MAIL_USERNAME = '<myemail>@gmail.com',
    MAIL_PASSWORD = '<mypassword>'
)
@app.route('/',methods=['GET'])
def main_page():
    iform=iPhoneForm()
    return render_template("user.html", iform=iform)

@app.route('/email',methods=['POST'])
def email():
    msg = Message(
          'Hello',
       sender=request.body['email'],
       recipients=
           ['marshall.a.x@gmail.com'])
    msg.body = "This is the email body"
    mail.send(msg)
    return "Sent"

然后在页面上，我有：

<form action="{{ url_for('email') }}" method="POST">
                            <p id="contact-copy">Enter your email below and we will notify you when Snappie becomes available on the app store</p>
                            {{ iform.email.label }}
                            {{ iform.email }}
                            {{ iform.submit }}
                        </form>

如您所见，我正在使用 flask-wtforms 并询问 flask-mail。现在这是我在提交带有电子邮件地址的表单时遇到的错误：

这是什么意思，我该如何解决？

Answer 1

您在创建 Mail 对象后更新了 app 配置，因此它可能仍在使用默认服务器和端口（即 localhost:25）。尝试调换它们的顺序：

app = Flask(__name__)
app.config.update(
    #EMAIL SETTINGS
    MAIL_SERVER='smtp.gmail.com',
    MAIL_PORT=465,
    MAIL_USE_SSL=True,
    MAIL_USERNAME = '<myemail>@gmail.com',
    MAIL_PASSWORD = '<mypassword>'
)
mail = Mail(app)
