我正在使用 Flask 框架作为后端开发 Web 应用程序，并且需要提供身份验证。
由于这是一个内部应用程序，将在我们的本地域上使用，因此我选择使用已有的域凭据对用户进行身份验证。
我使用的方法是从 pywin32 中调用 win32security.LogonUser，成功登录后返回一个句柄。
我尝试理解 Flask-Login 的工作原理，但是 @login_manager.user_loader 回调让我感到困惑。
它说我应该提供一个 ID，可以用来重新加载用户，但是我没有数据库或持久存储来提供此映射，因为我只关心检查用户是否通过身份验证。
我的 User 类看起来像这样：
class User(flask_login.UserMixin):
def __init__(self,username):
self.username = username
self.id = ???
如何使用id，并且这个id如何映射回该实例？
LDAP_SERVER = "yourldapserver"
LDAP_PORT = 390033 # your port
import ldap
def login(email, password):
ld = ldap.open(LDAP_SERVER, port=LDAP_PORT)
try:
ld.simple_bind_s(email, password)
except ldap.INVALID_CREDENTIALS:
return False
return True
使用ldap3实现flask-login的简单示例。
from flask_ldap3_login.forms import LDAPLoginForm
from flask_ldap3_login import LDAP3LoginManager, AuthenticationResponse
from flask_login import LoginManager, login_user, UserMixin, current_user
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret'
app.config['DEBUG'] = 'True'
# Setup LDAP Configuration Variables. Change these to your own settings.
# Hostname of your LDAP Server
app.config['LDAP_PORT'] = 636
# Hostname of your LDAP Server
app.config['LDAP_HOST'] = 'ldap-name.com'
app.config['LDAP_USE_SSL'] = True
# Base DN of your directory
app.config['LDAP_BASE_DN'] = 'dc=Hostname,dc=com'
# Users DN to be prepended to the Base DN
app.config['LDAP_USER_DN'] = 'ou=people'
# Groups DN to be prepended to the Base DN
app.config['LDAP_GROUP_DN'] = 'cn=ldap-groupname,ou=groups'
# The RDN attribute for your user schema on LDAP
app.config['LDAP_USER_RDN_ATTR'] = 'uid'
# The Attribute you want users to authenticate to LDAP with.
app.config['LDAP_USER_LOGIN_ATTR'] = 'uid'
# The Username to bind to LDAP with
app.config['LDAP_BIND_USER_DN'] = 'uid'
# The Password to bind to LDAP with
app.config['LDAP_BIND_USER_PASSWORD'] = 'pwd'
login_manager = LoginManager(app) # Setup a Flask-Login Manager
ldap_manager = LDAP3LoginManager(app) # Setup a LDAP3 Login Manager.
# Create a dictionary to store the users in when they authenticate
# This example stores users in memory.
users = {}
# Declare an Object Model for the user, and make it comply with the
# flask-login UserMixin mixin.
class User(UserMixin):
def __init__(self, dn, username, data):
self.dn = dn
self.username = username
self.data = data
def __repr__(self):
return self.dn
def get_id(self):
return self.dn
# Declare a User Loader for Flask-Login.
# Simply returns the User if it exists in our 'database', otherwise
# returns None.
@login_manager.user_loader
def load_user(id):
if id in users:
return users[id]
return None
# Declare The User Saver for Flask-Ldap3-Login
# This method is called whenever a LDAPLoginForm() successfully validates.
# Here you have to save the user, and return it so it can be used in the
# login controller.
@ldap_manager.save_user
def save_user(dn, username, data, memberships):
user = User(dn, username, data)
users[dn] = user
return user,username
@app.route('/', methods=['GET', 'POST'])
def login():
# exists in LDAP.
form = LDAPLoginForm()
if form.validate_on_submit():
# Successfully logged in, We can now access the saved user object
# via form.user.
a = login
return redirect(url_for('mainpage'))
return render_template('login.html',form=form)
else:
return render_template('error.html')
self.id应该是一个唯一的字符串。它可以是以下之一：
只需选择一个，并明智地选择。我更喜欢sAMAcountName用于我的工作。这需要您在ldap_bind后进行LDAPSearch。
第一次无需身份验证的绑定（以查找DN）应使用应用程序用户进行，以避免信息泄漏（如果您被黑客攻击）。
Ldap连接是资源=>使用上下文管理器
with ldap.open(LDAP_SERVER, port=LDAP_PORT) as ld:
# do the search/bind/search here
