实现 Python Flask-Security 时如何获取当前用户？-解网

问：

我正在使用 Flask-Security 为我的应用程序设置用户身份验证，但我正在努力获取当前登录用户的电子邮件地址或 ID，以便我可以查询包含该特定用户详细信息的表。我只是使用了标准代码。

这里的另一个问题提出了以下建议，但没有奏效：

my_user = current_user.get_id()

标准代码：

from flask import Flask, render_template
from flask_sqlalchemy import SQLAlchemy
from flask_security import Security, SQLAlchemyUserDatastore, \
    UserMixin, RoleMixin, login_required

# Create app
app = Flask(__name__)
app.config['DEBUG'] = True
app.config['SECRET_KEY'] = 'super-secret'
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite://'

# Create database connection object
db = SQLAlchemy(app)

# Define models
roles_users = db.Table('roles_users',
        db.Column('user_id', db.Integer(), db.ForeignKey('user.id')),
        db.Column('role_id', db.Integer(), db.ForeignKey('role.id')))

class Role(db.Model, RoleMixin):
    id = db.Column(db.Integer(), primary_key=True)
    name = db.Column(db.String(80), unique=True)
    description = db.Column(db.String(255))

class User(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(255), unique=True)
    password = db.Column(db.String(255))
    active = db.Column(db.Boolean())
    confirmed_at = db.Column(db.DateTime())
    roles = db.relationship('Role', secondary=roles_users,
                            backref=db.backref('users', lazy='dynamic'))

# Setup Flask-Security
user_datastore = SQLAlchemyUserDatastore(db, User, Role)
security = Security(app, user_datastore)

# Create a user to test with
@app.before_first_request
def create_user():
    db.create_all()
    user_datastore.create_user(email='[email protected]', password='password')
    db.session.commit()

# Views
@app.route('/')
@login_required
def home():
    return render_template('index.html')

if __name__ == '__main__':
    app.run()

python flask flask-security

from flask import Flask, session, redirect, url_for, escape, request

app = Flask(__name__)

@app.route('/')
def index():
    if 'username' in session:
        print("Currents user's ID is %s" % session['id']
        return 'Logged in as %s' % escape(session['username'])
    return 'You are not logged in'

@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'POST':
        session['username'] = request.form['username']
        session['email'] = request.form['email']
        session['id'] = request.form['id']
        return redirect(url_for('index'))
    return '''
        <form method="post">
            <p><input type=text name=username>
            <p><input type=submit value=Login>
        </form>
    '''

@app.route('/logout')
def logout():
    # remove the username from the session if it's there
    session.pop('username', None)
    session.pop('email', None)
    session.pop('id', None)
    return redirect(url_for('index'))

# set the secret key.  keep this really secret:
app.secret_key = 'A0Zr98j/3yX R~XHH!jmN]LWX/,?RT'

最好为此使用会话。您可以存储会话信息，然后在任何地方使用它。

在您的登录函数中，只需存储以下值：首先从 Flask 导入会话。然后像这样使用。

session['username'] = login_form.username.data

然后像在模板中一样使用它。{{ session['username'] }}
