Question

我正在尝试使用Redis＆RQ设置发送电子邮件的任务，但是，“ RQ Worker”在使用该功能在q.enqueue之外发送电子邮件时返回运行时错误。

app / routes.py

routes = Blueprint("routes", __name__)
r = Redis()
q = Queue(connection=r)

def sendEmail_task(recipient, message):
    msg = Message("Test Email", sender=("Me", "shawkyelshazly2@gmail.com"), 
    recipients=[recipient])
    msg.body = message
    msg.send(mail)

@routes.route("/send_email", methods=["POST", "GET"])
def send_mail():
    if request.method == "POST":
        recipient = request.form.get('email')
        message = request.form.get('message')
        job = q.enqueue(sendEmail_task, recipient, message)
        return redirect(url_for("routes.email_sent"))

    return render_template("send_email.html")

app / __ init __。py

mail = Mail()

def create_app(config_class = Config):
    app = Flask(__name__)
    from app.routes import routes
    app.register_blueprint(routes)    
    app.config.from_object(Config)

    with app.app_context():
        mail.init_app(app)

    return app

run.py

哪个在应用程序文件夹之外

    from app import create_app

    app = create_app()

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

您可能缺少app.app_context().push()。《 Flask Mega教程》的作用类似于this，但我已经在任务内完成了。

RQ Python“在应用程序上下文之外工作”
