這篇文章主要介紹python實(shí)現(xiàn)通過flask和前端進(jìn)行數(shù)據(jù)收發(fā)的方法,文中介紹的非常詳細(xì),具有一定的參考價(jià)值,感興趣的小伙伴們一定要看完!
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 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"> <title>echarts</title> <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>
