基于 Ajax 请求的 Flask-Login 认证

index.html
example.py

## index.html

```index.html


    
        
    
    
        

        未点击
        
        
    

example.py

from flask import Flask, request, jsonify, render_template
from flask_login import LoginManager, current_user, login_required
login_manager = LoginManager()

app = Flask(__name__)
login_manager.init_app(app)

class User:
    
    def __init__(self,user_name):
        self.id = 'test_id'
        self.user_name = user_name

    @property
    def is_active(self):
        return True

    @property
    def is_authenticated(self):
        return True

    @property
    def is_anonymous(self):
        return False

    def get_id(self):
        try:
            return text_type(self.id)
        except AttributeError:
            raise NotImplementedError('No `id` attribute - override `get_id`')

user = User("leetao")

@login_manager.request_loader
def load_from_request(request):
    api_key = request.args.get('api_key')
    if api_key == 'test_login':
        return user
    return None

@app.route('/hello')
@login_required
def hello_world():
    print(current_user.user_name)
    return jsonify('Hello, World!')

@app.route("/")
def index():
    return render_template("index.html")

结果

为了方便理解,我截了两张图,一张是 api_key 正确的情况下,一张是 错误的情况下

api_key 正确

api_key 错误
