在Python中撰寫Elasticsearch身份驗證
[英]Compose for Elasticsearch Authentication in Python
問題描述
我在使Python Elasticsearch庫與Bluemix的Compose for Elasticsearch產品一起使用時遇到問題。 當我對使用IBM容器創建的Elasticsearch集群使用以下代碼時，它連接得很好。
運行帶有Shield插件的Elasticsearch的IBM Container Cluster以進行用戶認證
(venv) ❯ python
>>> import requests
>>> import elasticsearch
>>> from elasticsearch import Elasticsearch, RequestsHttpConnection
>>> es = Elasticsearch(
... host='clustertestv5.mybluemix.net',
... port=80,
... http_auth=('es_admin', 'REDACTED'),
... timeout=60)
>>> es.info()
{u'cluster_name': u'elasticsearch', u'tagline': u'You Know, for Search', u'version': {u'lucene_version': u'5.5.0', u'build_hash': u'218bdf10790eef486ff2c41a3df5cfa32dadcfde', u'number': u'2.3.3', u'build_timestamp': u'2016-05-17T15:40:04Z', u'build_snapshot': False}, u'name': u'Forgotten One'}
當我嘗試使用相同的代碼但針對Bluemix提供的Elasticsearch集群進行身份驗證時，它失敗並顯示ConnectionError響應。
(venv) ❯ python
>>> import requests
>>> import elasticsearch
>>> from elasticsearch import Elasticsearch, RequestsHttpConnection
>>> es1 = Elasticsearch(
... host='bluemix-sandbox-dal-9-portal.3.dblayer.com',
... port=15206,
... http_auth=('admin', 'REDACTED'),
... timeout=60)
>>> es1.info()
Traceback (most recent call last):

elasticsearch.exceptions.ConnectionError: ConnectionError(('Connection aborted.', BadStatusLine("''",))) caused by: ProtocolError(('Connection aborted.', BadStatusLine("''",)))
>>> quit()
對Compose群集進行的直接卷曲顯示用戶名和密碼正確，因此我知道這不會導致連接問題。
(venv) ❯ curl -k 'https://bluemix-sandbox-dal-9-portal.3.dblayer.com:15206/'
<html><body><h1>401 Unauthorized</h1>
You need a valid user and password to access this content.

(venv) ❯ curl -k -u admin:REDACTED 'https://bluemix-sandbox-dal-9-portal.3.dblayer.com:15206/'
{
"name" : "elastic_search56_bluemix_sandbox_dal_9_data_2_dblayer_com",
"cluster_name" : "bmix_dal_yp_xxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"version" : {
"number" : "2.4.0",

"build_timestamp" : "2016-08-29T09:14:17Z",
"build_snapshot" : false,
"lucene_version" : "5.5.2"
},
"tagline" : "You Know, for Search"
}

在創建ES連接的python代碼中，您缺少選項。
添加： use_ssl=True
屆時它將抱怨缺少證書驗證，但將繼續進行。 要完善該功能，您應該使用VCAP連接信息中提供的證書以及verify_ssl=True選項。 該選項默認為False 。 注意：默認行為等同於您對curl使用-k選項。
