使用Flask-Mail在Gmail帐户中未发送邮件 [英] Mail Not Sent In Gmail Account Using Flask-Mail
问题描述
我正在尝试通过向Gmail帐户发送电子邮件来添加重置用户密码的功能.我一直在关注 CoreySchafer YouTube教程和
I am trying to add a functionality of resetting user password by sending email to a Gmail account. I have been following CoreySchafer YouTube Tutorial and Miguel Grinberg Tutorial to achieve this.
总体思路是，将向用户提示密码重设请求表"，他们将在其中输入要重设密码的电子邮件地址.单击请求重设密码"后，将显示一条消息，表明已将电子邮件发送到其Gmail帐户.通过单击电子邮件中的链接，用户将能够重置其密码.
The overall idea is user will be prompted with a Password Reset Request Form where they will enter the email address for which they want to reset the password. After clicking the "Request Reset Password", a message will be displayed that an email has been sent to their Gmail account. By clicking the link from the email, the user will be able to reset their password.

我已将环境变量保存在根目录的.env文件中.
I have saved the environment variables in .env file in the root directory.
SECRET_KEY="simple-is-better-than-complex"
MAIL_SERVER="smtp.googlemail.com"
MAIL_PORT=587
MAIL_USE_TLS=True
MAIL_USERNAME="jeet.java.13"
MAIL_PASSWORD="pass123"
还在项目根目录中创建了config.py文件.
Also created the config.py file in the project root directory.
from dotenv import load_dotenv
load_dotenv(override=True)
import os
basedir = os.path.abspath(os.path.dirname(__file__))
# Application Configurations
class Config(object):
# Function: Getting Environment Variables
def get_env_var(name):
try:
return os.environ[name]
except KeyError:
message = "Expected Environment Variable '{}' Not Set!".format(name)
raise Exception(message)
# SECRET_KEY Configuration
SECRET_KEY = os.getenv("SECRET_KEY")
SQLALCHEMY_DATABASE_URI = "sqlite:///" + os.path.join(basedir, "tms.db")
SQLALCHEMY_TRACK_MODIFICATIONS = False
# EMAIL CONFIGURATION
MAIL_SERVER = os.getenv("MAIL_SERVER")
MAIL_PORT = int(os.getenv("MAIL_PORT")) or 25
MAIL_USE_TLS = os.getenv("MAIL_USE_TLS")
MAIL_USERNAME = os.getenv("MAIL_USERNAME")
MAIL_PASSWORD = os.getenv("MAIL_PASSWORD")
ADMINS = ["jeet.java.13@gmail.com"]
终端结果:
"POST /reset_password HTTP/1.1" 302 -
我还为我的Gmail帐户打开了安全性降低的应用程序"，但仍无法发送电子邮件.在执行Flask应用程序期间，终端没有错误.
I have also turned ON the "Less Secure Apps" for my Gmail Account, but the email still can't be sent. There is no error in the terminal during the execution of the Flask Application.
期待您的大力支持.
推荐答案
问题已解决.在定义环境变量时，MAIL_USERNAME必须是完整的电子邮件(Gmail)地址；不仅是Gmail ID.
Problem solved. While defining the environment variables, MAIL_USERNAME need to be the full email(Gmail) address; not only the Gmail ID.
