python实现通过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
)
前端代码：
