Python: elasticsearch.exceptions.NotFoundError: NotFoundError(404, '{"code":404 ,"message":"HTTP 404 Not Found"}')

Question

我想在 Python 中使用 ElasticSearch 从给定的 URL(带有前缀)获取数据。这是我的代码:

if __name__ == '__main__':
    username = "xxxx"
    password = "xxxx"
    url = "http://xxxx.xxx:80/xxxx/xxxx/" 
  
    _es = Elasticsearch([url], http_auth=(username, password))
    if _es.ping():
        print('Connect')
        print(_es)
        res = _es.search(index='index1', body={"query": {"match_all": {}}})
        print(res)
    else:
        print('It could not connect!')

实际上，我可以 ping _e，而 _es 将是一个弹性对象:

<Elasticsearch([{'host': 'xxxx.xxx', 'url_prefix': 'xxxx/xxxx/', 'port': 80}])>

此外，为了验证我的 URL、端口和前缀，我在 Postman 中进行了检查，我可以正确获取 Json 格式的数据。但是当我在 Python 中运行代码时，我收到以下错误:

Connect
<Elasticsearch([{'host': 'xxxx.xxx', 'url_prefix': 'xxxx/xxxx/', 'port': 80}])>
Traceback (most recent call last):

    res = _es.search(index='index1', body={"query": {"match_all": {}}})

有什么想法吗？

请使用 try except 和 elasticsearch 异常，如下所示:

from elasticsearch import Elasticsearch, exceptions

es = Elasticsearch()

try:
    res2 = es.delete(index='my_index', id='not exist id')
except exceptions.NotFoundError:
    pass
