背景：
后端 flask（python）处理数据，页面实时刷新，类似于打包页面的动态展示，展示效果如图：
代码如下：
前端主要使用以下循环处理， 2--- 2秒刷新一次
{% if 0 == stop %}
<meta http-equiv="refresh" content="2;url={{ url_for('test') }}">
{% endif %}
html：
1 <html> 2 <head> 3 {% if 0 == stop %} 4 <meta http-equiv="refresh" content="2;url={{ url_for('test') }}"> 5 {% endif %} 6 </head> 7 <body> 8 9 <div class="header"> 10 <h4>标题XXX</h4> 11 </div> 12 <div class="body"> 13 <form class="form" action="/test" method="post"> 14 <div class="form"> 15 <button class="btn btn-primary" type="submit" >开始</button> 16 </div> 17 </form> 18 </div> 19 20 <div class="c" id="show2" > 21 <div class="header"> 22 <h4>结果展示：</h4> 23 <p style="white-space:pre-line;">{{ s }}</p> 24 </div> 25 26 </div> 27 </body> 28 <!- 根据自己实际路径填写> 29 <script type="text/javascript" src="static/js/main.min.js"></script> 30 <script type="text/javascript" src="static/js/jquery.min.js"></script> 31 32 <script type="text/javascript"> 33 34 35 </script> 36 </html>
python代码如下：
1 from flask import Flask,render_template,request 2 3 app = Flask(__name__) 4 5 @app.route('/test',methods=['GET','POST']) 6 def test(): 7 s = testDis() 8 stop = 0 9 # notify(access_token, ('调用地址：','tools_updateTimes'), ('调用名称','修改司机交易测试'),'','','','') 10 if s == 'z': 11 stop = 1 12 return render_template("test/test.html",s = s,stop=stop) 13 14 15 import random 16 def testDis(): 17 s =random.choice('abcdefghijklmnopqrstuvwxyz!@#$%^&*()') 18 if s == 'a': 19 s = s+'\n'+s 20 return s 21 22 if __name__ == '__main__': 23 app.run(host='0.0.0.0')
