## index.html

```index.html

test login by Leetao

未点击

var load_msg = function () {

$.get('/hello?api_key=test_login',function(data){

$('#test_login')[0].innerText = data

})

}

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
