Flask环境搭建

准备

conda create -n flask python=3.8
conda activate flask 
# 退出虚拟环境
conda deactivate

安装flask

pip install flask -i https://pypi.douban.com/simple

创建flask项目

手动创建项目目录 flaskdemo,在目录中创建manage.py.在pycharm中打开项目并指定上面创建的虚拟环境
创建一个flask框架的启动入口文件，名字可以是app.py/run.py/main.py/index.py/manage.py/start.py

manage.py

from flask import flask

app = Flask(__name__)

settings = {
    "DEBUF": True
}

@app.route("/")
def index():
    return "hello flask!!!"

if __name__ == '__main__':
    # app.run(host="0.0.0.0", port=5000, debug=True)
    app.run()    # 默认值，host="127.0.0.1", port=5000, debug=False)
