在Pyramid中实现邮件验证的完整流程

本示例代码演示了如何使用Pyramid框架实现用户注册邮箱验证的完整流程，包括发送验证邮件、验证链接响应、验证成功或失败的页面提示等。

# 邮件发送函数
from pyramid_mailer import get_mailer
from pyramid_mailer.message import Message

mailer = get_mailer(request)

# 生成验证链接
verification_link = request.route_url('verify_email',
                                       user_id=encode_user_id(user_id),
                                       verification_key=verification_key)

# 构建邮件消息
message = Message(subject='Please verify your email address',
                  sender='noreply@example.com',
                  recipients=[email],
                  body='Please click the following link to verify your email address: %s' % verification_link)

# 发送邮件
mailer.send_immediately(message)

# 验证链接视图
@view_config(route_name='verify_email', renderer='templates/verify_email.jinja2')
def verify_email_view(request):
    user_id = decode_user_id(request.matchdict['user_id'])
    verification_key = request.matchdict['verification_key']
    user = get_user_by_id(user_id)
    if user.verification_key == verification_key:
        user.email_verified = True
        user.verification_key = None
        message = 'Thank you for verifying your email address.'
    else:
        message = 'Sorry, the verification link you clicked is invalid.'
    return {'message': message}

# 成功或失败页面提示
@view_config(route_name='verification_success', renderer='templates/verification_success.jinja2')
def verification_success_view(request):
    return {'message': 'Your email address has been successfully verified.'}

@view_config(route_name='verification_failure', renderer='templates/verification_failure.jinja2')
def verification_failure_view(request):
    return {'message': 'Sorry, something went wrong with the email verification process.'}
