Question

我在localhost（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，它会返回

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，我尝试通过谷歌浏览器访问http://localhost:9200/customer/_search?q=James&size=5，但它确实有效。

请帮我解决问题

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

具有不同端口的同一localhost上的python localhost请求
