邮箱配置
Flask-Security与Flask-Mail相结合去处理所有⽤户与⽹站之间的邮箱通信，所以为Flask-Mail配置您的邮箱服务信息是⾮常重要的。
下⾯的代码展⽰了⼀个简单的配置，您可以将下⾯的代码直接加⼊您的Flask应⽤代码中:

# 在⽂件上⾯
from flask_mail import Mail
# 在\'Create app\'后
[\'MAIL_SERVER\'] = \'\'
[\'MAIL_PORT\'] = 465
[\'MAIL_USE_SSL\'] = True
[\'MAIL_USERNAME\'] = \'username\'
[\'MAIL_PASSWORD\'] = \'password\'
mail = Mail(app)
代理配置
⽤户追踪特性需要在HTTP代理环境中添加⼀个额外的配置。下⾯的代码展⽰了⼀个单个HTTP代理的配置。
# 在⽂件最上⾯
from import ProxyFix
# 在\'Create app\'后
_app = ProxyFix(_app, num_proxies=1)
