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Miguel Grinberg 教程来实现这一点。
总体思路是用户将收到密码重置请求表的提示，他们将在其中输入他们想要重置密码的电子邮件地址。单击“请求重置密码”后，将显示一条消息，表明电子邮件已发送到他们的 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。
相关文件名的代码如下：
文件：路由.py
# Reset Password Request Route
@app.route("/reset_password", methods = ["GET", "POST"])
def reset_password_request():
if current_user.is_authenticated:
return redirect(url_for("dashboard"))
form = ResetPasswordRequestForm()
if form.validate_on_submit():
user = User.query.filter_by(email = form.email.data).first()
if user:
send_password_reset_email(user)
flash("Please check your email for the instructions to reset your password")
return redirect(url_for("login"))
return render_template("reset_password_request.html", title = "Request For Reset Password", form = form)
# Password Reset Route
@app.route("/reset_password/<token>", methods = ["GET", "POST"])
def reset_password(token):
if current_user.is_authenticated:
return redirect(url_for("dashboard"))
user = User.verify_reset_password_token(token)
if not user:
flash("Invalid Token")
return redirect(url_for("reset_password_request"))
form = ResetPasswordForm()
if form.validate_on_submit():
user.set_password(form.password.data)
db.session.commit()

return redirect(url_for("login"))
return render_template("reset_password.html", title = "Reset Password", form = form)

我已将环境变量保存在根目录的 .env 文件中。
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。
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“安全性较低的应用程序”，但仍然无法发送电子邮件。在执行 Flask 应用程序期间，终端中没有错误。
期待您最亲切的支持。
