python代码:#-*-coding:utf-8-*-fromflaskimportFlask,jsonify,render_template,requestimportjsonapp=Flask(__name__)#实

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:


<!DOCTYPE html>
<html lang="en">
 
<head>
 <meta charset="UTF-8">
 <meta name="viewport" content="width=device-width, initial-scale=1.0">
 <meta http-equiv="X-UA-Compatible" content="ie=edge">

 <style type="text/css">

 }
 
 body {
 margin: 0px;
 padding: 0px
 }
 
 div {
 float: left;
 }
 
 #container {
 width: 50%;
 height: 100%;
 }
 
 #info {
 padding: 10px 20px;
 }
 </style>
</head>
 
<body>
 <div id="container"></div>
 <div id="info">数据展示:</div>
 <script src="http://apps.bdimg.com/libs/jquery/2.1.4/jquery.js"></script>
 <script>
 var student = {
 email:'123456',
 phone:'121421421',
 };
 
 var senddata = JSON.stringify(student);
 
 console.log(senddata)
 
 setInterval(function query() {
 $.ajax({
 url: "test_post/nn",
 type: "POST",
 data: senddata,
 dataType: "json",
 success: function (data) {
 console.log(data)
 }
 })
 }, 1000);
 
 
 </script>
 
</body>
 
</html>
