今天小編就為大家分享一篇python實(shí)現(xiàn)通過(guò)flask和前端進(jìn)行數(shù)據(jù)收發(fā),具有很好的參考價(jià)值,希望對(duì)大家有所幫助。一起跟隨小編過(guò)來(lái)看看吧

python代碼:

# -*- coding: utf-8 -*-
from flask import Flask,jsonify,render_template,request
import json
 
app = Flask(__name__)#實(shí)例化app對(duì)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都可以訪問(wèn)
      port=7777,#端口
      debug=True
      )

前端代碼:

<!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">
    html,
    body {
      width: 100%;
      height: 100%;
    }
 
    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">數(shù)據(jù)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>

以上這篇python實(shí)現(xiàn)通過(guò)flask和前端進(jìn)行數(shù)據(jù)收發(fā)就是小編分享給大家的全部?jī)?nèi)容了,希望能給大家一個(gè)參考,也希望大家多多支持腳本之家。
