扩展

蓝图内置扩展(实现的是路由的拆分)

 1 ‘‘‘----------- app.py -------------‘‘‘
 2 from flask import Flask
 3 from users_views import blue1
 4 from orders_views import blue2
 5 
 6 app = Flask(__name__)
 7 
 8 # 路由注册
 9 app.register_blueprint(blueprint=blue1)
10 app.register_blueprint(blueprint=blue2)
11 
12 
13 if __name__ == ‘__main__‘:
14     app.run()

 1 ‘‘‘ ------------ users_views.py ---------------‘‘‘
 2 from flask import Blueprint
 3 # blue1 的设置(名字，导入的名字，前缀名称)
 4 blue1 = Blueprint("blue1",__name__, url_prefix="/users")
 5 
 6 # 用blue1设置路由，用前缀名字区分相同名字的路由：http://127.0.0.1:5000/users/
 7 @blue1.route("/")
 8 def index():
 9     return "用户的 Blue 信息"
10 
11 
12 @blue1.route("/user/")
13 def home():
14     return "用户信息"

 1 ‘‘‘ ----------- orders_vieews.py ----------‘‘‘
 2 from flask import Blueprint
 3 # blue2 的设置(名字，导入的名字，前缀名称)
 4 blue2 = Blueprint("blue2", __name__, url_prefix="/orders")
 5 
 6 # 用blue2设置路由，用前缀名字区分相同名字的路由：http://127.0.0.1:5000/orders/
 7 @blue2.route("/")
 8 def haha():
 9     return "订单的 blue2 信息"
10 
11 
12 @blue2.route("/orders/")
13 def ppp():
14     return "订单信息"

静态文件路径

1 from flask import Flask
2 from users_views import blue1
3 from orders_views import blue2
4 # 静态文件路径配置。static_folder=‘news/static‘ 是配置新的静态文件的路径
5 app = Flask(__name__,static_folder=‘news/static‘)
6 
7 # 路由注册
8 app.register_blueprint(blueprint=blue1)
9 app.register_blueprint(blueprint=blue2)

终端输入插件扩展：flask-script

• 安装：pip install flask-script
• 配置：
  

   1 from flask import Flask
   2 from flask_script import Manager
   3 
   4 app = Flask(__name__)
   5 # 配置flask-script
   6 manager = Manager(app=app)
   7 
   8 @app.route(‘/‘)
   9 def hello_world():
  10     return ‘Hello World!‘
  11 
  12 # 使用flask-script
  13 if __name__ == ‘__main__‘:
  14     manager.run()

  flask-script

   

• 使用：在终端键入：python app.py runserver 
  • 查看帮助文档：python app.py runserver --help
  • 设置指定端口：python app.py runserver -h ip地址 -p 端口号
  • 设置自动重启：python app.py runserver -r
  • 设置调试模式：python app.py runserver -d
