有人能告诉我如何在flask中查看会话变量,以便我可以检索当前登录的用户吗?使用我的'for loop',我可以查看迭代的所有项目,但我需要当前登录的用户...
提前致谢
app.py
engine = create_engine('sqlite:///dude.db', echo=True)
app = Flask(__name__)
@app.route('/')
def home():
if session.get('logged_in'):
Session = sessionmaker(bind=engine)
s = Session()
user = s.query(User.username)
for i in user:
print i
return render_template('index.html', user = user)
else:
return render_template('index.html')
答案 0 :(得分:1)
看起来你混淆了这两件事:
Flask会话的一般模式(例如,使用您的密钥签名加密cookie,您必须将secret_key
配置集设置为使用这些),如下所示:
from flask import session, redirect, url_for, render_template
@app.route('/login/')
def login():
# logic to sign in user
# then set session variable
session['profile'] = {"user_id": 5, "user_name": "Tom"}
return redirect(url_for('main'))
@app.route('/logout/')
def logout():
# logic to sign out user
# clear session
session.clear()
return redirect(url_for('main'))
@app.route('/')
def main():
user = None
if 'profile' in session:
user = session['profile']
return render_template('index.html', user=user)
