使用Python索引elasticsearch中的JSON文件?

我有一堆JSON文件(100),命名为merged_file 1.json,merged_file 2. json等等。

如何使用python(elasticsearch_dsl)将所有这些文件索引到elasticsearch?

我正在使用此代码,但它似乎不起作用:

from elasticsearch_dsl import Elasticsearch
import json
import os
import sys

es = Elasticsearch()

json_docs =[]

directory = sys.argv[1]

for filename in os.listdir(directory):
    if filename.endswith('.json'):
        with open(filename,'r') as open_file:
            json_docs.append(json.load(open_file))

es.bulk("index_name", "type_name", json_docs)

JSON看起来像这样:

{"one":["some data"],"two":["some other data"],"three":["other data"]}

我该怎么做才能做到这一点?

对于此任务,您应该使用elasticsearch-pypip install elasticsearch):

from elasticsearch import Elasticsearch, helpers
import sys, json

es = Elasticsearch()

def load_json(directory):
    " Use a generator, no need to load all in memory"
    for filename in os.listdir(directory):
        if filename.endswith('.json'):
            with open(filename,'r') as open_file:
                yield json.load(open_file)

helpers.bulk(es, load_json(sys.argv[1]), index='my-index', doc_type='my-type')
