flask-蓝图

蓝图作用

相当于一个功能模块，能做到即插即用

蓝图运用示例1：

简单项目示例

 account.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from flask import Blueprint
from flask import render_template
from flask import request

account = Blueprint('acc', __name__)


@account.route('/login.html', methods=['GET', "POST"])
def login():
    return render_template('login.html')

blog.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from flask import Blueprint,url_for

blog = Blueprint('blog', __name__)

@blog.before_request
def a():
    print("wo我是blog 的请求扩展")

@blog.route("/index")
def index():
    print(url_for("acc.login"))
    return "ok"

user.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from flask import Blueprint

user = Blueprint('user', __name__)

__init__.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from flask import Flask

app = Flask(__name__,template_folder='templates',static_folder='statics',static_url_path='/static')

@app.before_request
def a():
    print("我是app里面的befor_request")

from .views.account import account
from .views.blog import blog
from .views.user import user

app.register_blueprint(account)
app.register_blueprint(blog)
app.register_blueprint(user)

run.py

from pro_flask import app

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

复杂项目：

 admin/__init__.py

from flask import Blueprint

admin = Blueprint(
    'admin',
    __name__,
    template_folder='templates',
    static_folder='static'
)
from . import views

admin/views.py

from . import admin


@admin.route('/index')
def index():
    return 'Admin.Index'

web/__init__.py

from flask import Blueprint

web = Blueprint(
    'web',
    __name__,
    template_folder='templates',
    static_folder='static'
)
from . import views

web/views.py

from . import web

@web.route('/index')
def index():
    return 'Web.Index'

__init__.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from flask import Flask
from .admin import admin
from .web import web

app = Flask(__name__)
app.debug = True

app.register_blueprint(admin, url_prefix='/admin')
app.register_blueprint(web)

run.py

from pro_flask import app

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