python通过flask和前端进行数据收发

python代码：

# -*- coding: utf-8 -*-
from flask import Flask,jsonify,render_template,request
import json

app = Flask(__name__)#实例化app对象

testInfo = {}
num=10

@app.route('/test_post/nn',methods=['GET','POST'])#路由
def test_post():
    global num
    '''receive data'''
    recv_data = request.get_data()
    if recv_data:
        print recv_data
        json_re = json.loads(recv_data)
        print json_re['email']
        print json_re['phone']
    else:
        print("receive data is empty")

    '''send data'''
    num = num + 1
    testInfo['name'] = 'xiaoming'
    testInfo['age'] = num
    return json.dumps(testInfo)

@app.route('/')
def hello_world():
    return 'Hello World!'

@app.route('/index')
def index():
    return render_template('index.html')


if __name__ == '__main__':
    app.run(host='0.0.0.0',#任何ip都可以访问
            port=7777,#端口
            debug=True
            )
