1.为什么要学习Flask request 请求参数管理1.一个完整的系统组成分为两部分(后端api,前端页面)
* 前端页面负责用户体验交互式效果--将用户输入的数据传递给后端api进行计算和处理.
* 后端api负责业务模块功能实现-将预期的结果返回给前端页面**2.使用Bootstrap前端框架模拟form表单数据提交

from flask import Flask, render_template, request,Response
import os
import json
app = Flask(__name__)
@app.route(‘/login‘)
def upload_file():
return render_template(‘index.html‘)
@app.route(‘/Login‘, methods = [‘GET‘, ‘POST‘])
def uploader():
if request.method == ‘GET‘:
return Response(json.dumps({"code": 0, "data": "test"}), mimetype=‘application/json‘)
elif request.method == ‘POST‘:
name = request.form[‘name‘]
passwd = request.form[‘passwd‘]
if name and passwd:
return Response(json.dumps({"code": 0, "data": "user login success"}), mimetype=‘application/json‘)
else:
return Response(json.dumps({"code": 0, "data": "账号或密码未输入 "}), mimetype=‘application/json‘)
if __name__ == ‘__main__‘:
app.run(
host="0.0.0.0",
port=5050,
debug=True
