Duo modi pro utrem ad configuratione project onus

# 1. 导入flask核心类
from flask import Flask

# 2. 初始化web应用程序的实例对象
app = Flask(__name__)

"""第一种：flask项目加载站点配置的方式"""
# app.config["配置项"] = 配置项值
# app.config["DEBUG"] = False

"""第二种：flask项目加载站点配置的方式"""
# app.config是整个flask项目默认的配置属性，里面包含了所有的可用配置项，配置项的属性名都是大写字母或大小字母+下划线组成
config = {
    "DEBUG": True
}
app.config.update(config)

# 4. 可以通过实例对象app提供的route路由装饰器，绑定视图与uri地址的关系
@app.route("/")
def index():
    # 5. 默认flask支持函数式视图，视图的函数名不能重复，否则报错！！！
    # 视图的返回值将被flask包装成响应对象的HTML文档内容，返回给客户端。
    return "<h1>hello flask</h1>"


if __name__ == '__main__':
    # 3. 运行flask提供的测试web服务器程序
    app.run(host="0.0.0.0", port=5000)

Basic definition of profectus

Nomina itinerum et sententiarum globally unica esse debent et iterari non possunt, alioquin error afferetur.

# 1. 导入flask核心类
from flask import Flask

# 2. 初始化web应用程序的实例对象
app = Flask(__name__)

# 开启debug模式
app.config["DEBUG"] = True

# 参数1：rule设置当前视图的路由地址
# 惨呼2：methods，设置当前视图的HTTP请求方法，允许一个或多个方法，不区分大小写
@app.route(rule="/", methods=["get", "post"])
def index():
    return "<h1>hello flask1</h1>"

if __name__ == '__main__':
    # 3. 运行flask提供的测试web服务器程序
    app.run(host="0.0.0.0", port=5000)

Terminatio cursus Flask project

#  如果要基于开发环境在终端启动项目，设置环境变量如下：
export FLASK_DEBUG=True
# 如果要基于生产环境在终端启动项目，设置环境变量如下：
# export FLASK_DEBUG=Flase

# 找到创建flask应用的模块路径，例如：manage.py
# 则ubuntu等Linux下的终端：
export FLASK_APP=manage.py  # 这是临时设置，如果有永久设置，可以通过/etc/profile保存
# 2. 在当前虚拟环境中，如果安装了flask模块，则可以使用全局命令flask run，即可运行flask项目
flask run # 采用默认的127.0.0.1 和 5000端口运行项目 
flask run --host=0.0.0.0 --port=8088 # 可以改绑定域名IP和端口
