python - 在同一本地主机上的python本地主机请求具有不同的端口

Question

我在本地主机(http://localhost:5000)中使用Flash，并尝试使用python请求从elasticsearch请求json结果

这是我的代码

@app.route('/test')
def TestElasticsearch():
  url = "http://localhost:9200/customer/_search?q=James&size=5"
  r = requests.get(url)
  print r
  return r.text

当我通过谷歌浏览器访问 http://localhost:5000/test时，它返回

ConnectionError: HTTPConnectionPool(host='localhost', port=9200): Max retries exceeded with url: /customer/_search?q=James&size=5 (Caused by <class 'socket.error'>: [Errno 111] Connection refused)

请注意，我已经尝试通过Google chrome访问 http://localhost:9200/customer/_search?q=James&size=5，并且它可以正常工作。

请帮我找出问题所在

Try:

@app.route('/test')
def TestElasticsearch():
    import urllib
    url = 'http://localhost:9200/customer/_search?q=James&size=5'
    # GET is the default action
    response = urllib.urlopen(url)  
    # Output from the GET assuming response code was 200
    r = response.read()   
    print r
