Flask中的蓝图 --Blueprint

 

项目目录：

 

 蓝图必须使用 Blueprint实例化一个对象，Blueprint也是继承的Flask

#app1.views.py文件代码
#蓝图
from flask import Blueprint,render_template,send_file
#Blueprint 当作一个不能run的Flask实例

user = Blueprint("app01user",__name__,url_prefix="/admin",template_folder="/flsakdemo1/app01/templates",static_folder="/flsakdemo1/app01/static",static_url_path="/app01/static") #第一个参数蓝图名  url_prefix

@user.route("/loginOne")
def loginOne():
    return "I am app01user Blueprint loginOne func"

@user.route("/sendFiles")
def sendFiles():
    return send_file("01.png")

#app2.views.py文件代码

#蓝图
from flask import Blueprint
#Blueprint 当作一个不能run的Flask实例

user = Blueprint("app02user",__name__,url_prefix="/shopping") #第一个参数蓝图名  url_prefix url前缀：用于隔离相同url,蓝图名称不能重复，保证在app中唯一。
# app = Flask(__name__)

@user.route("/loginOne")
def loginOne():
    return "I am app02user Blueprint loginOne func"

 

使用蓝图

from flask import Flask

app = Flask(__name__)

#Flask中的蓝图 Blueprint
    #蓝图作用：功能隔离，路由隔离
#建立蓝图注册:结合app01，app02一起看
from flsakdemo1.app01.views import user
app.register_blueprint(user)
from flsakdemo1.app02.views import user as app02_user
app.register_blueprint(app02_user)




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