Pro*_*ill 1 python elasticsearch elasticsearch-5
我正在使用Elasticsearch数据库存储从网上提取的数据,但是当我尝试对数据库中的数据建立索引时,出现错误。
这是我用于创建和索引数据的代码:
es = Elasticsearch()
es.index(index='weather', doc_type='data', body=doc)

但是,当我运行该程序时,其中的第二行会导致错误,这是完整的回溯:

http_auth创建 ElasticSearch 客户端时,可以将 HTTP 基本身份验证传递给参数:
client = Elasticsearch(\n hosts=[\'localhost:5000\'],\n http_auth=(\'username\', \'password\'),\n)\ns = Search(using=client, index=\'something\')\nRun Code Online (Sandbox Code Playgroud)\n这假设您正在使用Urllib3HttpConnection具有参数的底层传输类http_auth。
\n\nRun Code Online (Sandbox Code Playgroud)\nclass elasticsearch.connection.Urllib3HttpConnection(host=\'localhost\', \n http_auth=None, \n ...,\n **kwargs) \n使用 urllib3 库和 http\n协议的默认连接类。
\n参数:
\n\n
\n- http_auth \xe2\x80\x93 可选的 http 身份验证信息,作为 \xe2\x80\x98:\xe2\x80\x99 分隔的字符串或元组
\n
有关身份验证的 SSL 和其他参数,请参阅文档的SSL 和身份验证部分:
\nfrom ssl import create_default_context\n\ncontext = create_default_context(cafile="path/to/cert.pem")\nes = Elasticsearch(\n [\'localhost\', \'otherhost\'],\n http_auth=(\'user\', \'secret\'),\n scheme="https",\n port=443,\n ssl_context=context,\n)\nRun Code Online (Sandbox Code Playgroud)\n
``缺少身份验证令牌''表示与该Elasticsearch实例进行对话之前需要进行身份验证。要为文档建立索引,用户必须具有写权限。您可以在如下所示的URL中包含用户名和密码:http:// user:password @ hostname:post
例如,在外壳中:
export ES_ENDPOINT="http://usernameWithWriteAccess:password@localhost:9200"

然后在python中:
es = Elasticsearch(os.environ['ES_ENDPOINT'])
