藍圖必須使用Blueprint例項化一個物件，Blueprint也是繼承的Flask

#app1.views.py檔案程式碼
#藍圖
from flask import Blueprint,render_template,send_file
#Blueprint 當作一個不能run的Flask例項

user = Blueprint("app01user",__name__,url_prefix="/admin",template_folder="/flsakdemo1/app01/templates",static_folder="/flsakdemo1/app01/static",static_url_path="
 
/app01/static") #第一個引數藍圖名  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檔案程式碼

#藍圖
from flask import Blueprint
#Blueprint 當作一個不能run的Flask例項

user = Blueprint("
 
app02user",__name__,url_prefix="/shopping") #第一個引數藍圖名  url_prefix url字首：用於隔離相同url,藍圖名稱不能重複，保證在app中唯一。
# app = Flask(__name__)

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

使用藍圖

from flask import Flask

app = Flask(__name__)

#Flask中的藍圖 Blueprint
    #藍圖作用：功能隔離，路由隔離
 

#建立藍圖註冊:結合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()
