flask搭建

1、定义路由app.py

from flask import Flask, request
from flask import Blueprint
app = Flask(__name__)
test = Blueprint('test', __name__)


@app.before_request
def before_request():
    print("before_request")
    print(request)


@app.after_request
def after_request(param):
    print("after_request")
    print(param.data)
    # resp =app.make_response('after')
    return param


@app.teardown_request
def teardown_request(ex):
    print("teardown_request")

2、定义main入口main.py

from app import app
from app import test
import testController
from flask import Flask, request

if __name__ == '__main__':
    # 通过蓝图实现请求上下文
    app.register_blueprint(test, url_prefix='/test')
    # 默认监听端口是5000
    # 一定要指定debug=False不然断点不命中
    app.run(host='0.0.0.0', port=888, debug=False)

3、定义控制器testController.py

from app import app
from app import test


@app.route('/hello', methods=['POST'])
def hello():
    return 'hello app!'


@test.route('/hello', methods=['POST'])
def hello():
    return 'hello test!'
