出现此错误尝试将 elasticsearch docker 容器与 elasticsearch-python 客户端连接。

    /home/raihan/dev/aims_lab/ai_receptionist/env/lib/python3.6/site-packages/elasticsearch/_sync/client/__init__.py:379: SecurityWarning: Connecting to 'https://localhost:9200' using TLS with verify_certs=False is insecure

elastic.py 中的内容

    host = "https://localhost:9200"
es = Elasticsearch(host, ca_certs=False, verify_certs=False)
print(es)

doc = {
    'author': 'kimchy',
    'text': 'Elasticsearch: cool. bonsai cool.',
    'timestamp': datetime.now(),
}
resp = es.index(index="test-index", id=1, document=doc)
print(resp['result'])

resp = es.get(index="test-index", id=1)
print(resp['_source'])

elasticsearch dockerfile 中的内容

FROM docker.elastic.co/elasticsearch/elasticsearch:7.12.0
RUN elasticsearch-plugin install --batch https://github.com/alexklibisz/elastiknn/releases/download/7.12.0.0/elastiknn-7.12.0.0.zip

urllib3==1.26.9 请求==2.27.1

【问题讨论】：

希望您通过身份验证访问 Elasticsearch url。因此，在主机变量中使用凭据 url 提及它，例如“user:pass@localhost:9200”

标签： python elasticsearch elasticsearch-plugin

【解决方案1】：

你应该将“https”改为“http”，这就是答案
