发送实时数据给客户与剑圣 [英] Send real time data to client with juggernaut

问题描述

我试图用烧瓶的juggernaut框架来发送实时信息给客户端浏览器，然后在

这是我的python代码：

  import flask 
 from flask.views从tweetStreamsRT导入MethodView 
从juggernaut导入StreamerRt 
导入Juggernaut 
 
 
 app = flask.Flask（__ name__）
 app.secret_key =xxxxx
 PORT = 8080 
 
 class View（MethodView）：
 
 def get（self）：
 return flask.render_template（'index .html'）
 
 def post（self）：
 results = StreamerRt（）。filter（track = [flask.request.form ['event']]）
 jug = Juggernaut（）
 jug.publish（'channel'，results）
返回self.get（）
 
 
 app.add_url_rule（'/'，view_func = View.as_view（'index'），methods = ['GET'，'POST']）
 app.debug = True 
 
 if __name__ ==__main__：
 print'听取http：// localhost：％s'％PORT 
 app.run（）
  

我的html页面是从基本html继承的页面：

  {％extendsbase.html％} 
 {％importforms.htmlas forms ％} 
 
 
 {％block page_header％} 
< div class =page-header> 
< h1>欢迎< / h1> 
< / div> 
 {％endblock％} 
 {％block content％} 
 
输入您要关注的活动< / h2> 
< form action =/method =post> 
< input type =textname =event/> 
< input type =submitvalue =提交查询/> 
< / form> 
结果：
< pre> 
< script type =text / javascriptcharset =utf-8> 
 var jug = new Juggernaut; 
 jug.subscribe（channel，function（data）{
 alert（Got data：+ data）;}）; 
< / script> 
 
< / pre> 
 {％endblock％} 
  

我很困惑为什么没有发送给客户端浏览器。

谢谢

Juggernout已被弃用 http://blog.alexmaccaw.com/killing-a-library
如果你关于围绕它构建应用程序，现在是切换到别的东西的正确时机。像EventSource一样 http://www.html5rocks.com/en/tutorials/eventsource/basics/

I have tried to use the juggernaut framework for flask in order to send real-time information to the client browser followinf the flask snippet at http://flask.pocoo.org/snippets/80/.

When I try to implement it for my code, it still does not provide a real-time output in the client browser.

This is my python code:

import flask
from flask.views import MethodView
from tweetStreamsRT import StreamerRt 
from juggernaut import Juggernaut


app = flask.Flask(__name__)
app.secret_key = "xxxxx"
PORT = 8080

class View(MethodView):

    def get(self):
        return flask.render_template('index.html')

    def post(self):
        results = StreamerRt().filter(track=[flask.request.form['event']])            
        jug = Juggernaut()
        jug.publish('channel', results)
        return self.get()


app.add_url_rule('/', view_func = View.as_view('index'), methods=['GET', 'POST'])
app.debug = True

if __name__ == "__main__":
    print 'Listening on http://localhost:%s' % PORT
    app.run()

My html page is, which inherits from a base html page:

{% extends "base.html" %}
{% import "forms.html" as forms %}


{% block page_header %}
  <div class="page-header">
    <h1>Welcome</h1>
  </div>
{% endblock %}
{% block content %}
  <h2>Enter the Event you would like to follow</h2>
      <form action="/" method="post">
            <input type="text" name="event" />
            <input type="submit" value="Submit Query" />
          </form>
            Results:
            <pre>
                <script type="text/javascript" charset="utf-8">
                    var jug = new Juggernaut;
                    jug.subscribe("channel", function(data){
                    alert("Got data: " + data);});
                </script>

            </pre> 
{% endblock %}

I'm confused as to why nothing is sent to the client browser.

Thanks

Juggernout is deprecated http://blog.alexmaccaw.com/killing-a-library If you're about to build your application around it it's the right time to switch to something else. Like EventSource http://www.html5rocks.com/en/tutorials/eventsource/basics/
