格式化elasticsearch-py的输出 [英] Format the output of elasticsearch-py

问题描述

我正在尝试将 python 客户端用于 elasticsearch 。这是一个最小的示例：

I'm trying to use the python client for elasticsearch. Here is a minimal example:

import logging
logging.basicConfig()

from elasticsearch import Elasticsearch as ES

print "Setup connection..."
es=ES(['localhost:8080'])
print "Done!"

print "Count number of users..."
print es.count(index='users')

输出为：

{u'count': 836780, u'_shards': {u'successful': 5, u'failed': 0, u'total': 5}}

我有两个问题：

1. 如何摆脱 u'（ u 后跟单引号）？


2. 如何提取count的值？我想我可以进行字符串操作，但这听起来像是错误的方式...。
   答案：如果输出保存到 res ，然后 res ['count']返回数字 836780`。

1. How do I get rid of the u' (u followed by a single quote )?
2. How can I extract the value of count? I guess I could do string manipulation, but that sounds like the wrong way.... Answer: if the output is saved to res, then res['count'] returns the number836780`.

推荐答案

elasticsearch.py​​将json响应转换为python字典，以便轻松提取信息。

elasticsearch.py convert json response to dictionary for python, so that it is easy to extract information.

即

{u'count': 836780, u'_shards': {u'successful': 5, u'failed': 0, u'total': 5}}

是python字典。

is python dictionary.

如果您希望将其包含在json结构中，则可以这样做，

If you wan to have it in json structure then you can do,

json.dumps()
