折腾：
［已解决］Flask-Login出错：AttributeError AnonymousUserMixin object has no attribute openid
之后，参考：
Flask-Login — Flask-Login 0.3.2 documentation
写的代码：
gLog.info(“record logged in for user=%s”, curUser) login_user(curUser, remember = True) # 第一个参数传入用户对象,第二个参数 传入 以后是否自动登陆 app.flash(u’用户 %s 登录成功’, curUser.nickname) |
又出错：

搜：
AttributeError: ‘Flask’ object has no attribute ‘flash’
Flask flash
Message Flashing — Flask Documentation (0.11)
好像是：
from flask import Flask, flash
然后用：
flash(‘You were successfully logged in’) |
而此处的：
app是：
app = Flask(__name__, instance_relative_config=True) |
所以去改为：
from flask import flash flash(u’用户 %s 登录成功’, curUser.nickname) |
就可以了。
－》不过此处没有继续去使用flask，因为还要模板html中获取对应的flash信息再显示。觉得麻烦。
［总结］
此处app.flash出错的原因是app是大写的Flask，而flash是小写的flask中的功能
所以报错。
解决办法是：
从flask导入flash，即可使用：
from flask import flash flash(u’login OK’) |
