ElasticSearch Python 基本操作

创建索引

from elasticsearch import Elasticsearch

es = Elasticsearch('192.168.149.96:9200')

mappings = {
    "mappings": {
            "properties": {
                "perName": {
                    "type": "keyword"
                },
                "schoolName": {
                    "type": "keyword"
                },
                "perGrade": {
                    "type": "double"
                },
                "position": {
                    "type": "keyword"
                },
                "proMonth": {
                    "type": "date",  # 可以接受如下类型的格式
                    "format": "yyyy-MM"
                },
                "detailedTime": {
                    "type": "date",
                    "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
                },
                "projectName": {
                    "type": "keyword"
                },
                "targetOutput": {
                    "type": "double"
                },
                "actualOutput": {
                    "type": "double"
                },
                "yieldReachingRate": {
                    "type": "double"
                },
                "lateness": {
                    "type": "double"
                },
                "overtime": {
                    "type": "double"
                },
                "workingHours": {
                    "type": "double"
                },
                "groupRanking": {
                    "type": "double"
                },
                "qualityInspection": {
                    "type": "double"
                },
                "numberOfCustomer": {
                    "type": "double"
                }
            }
    }
}

result = es.indices.create(index='new_source', body=mappings)
print(result)

删除索引

from elasticsearch import Elasticsearch

es = Elasticsearch('192.168.149.96:9200')

result = es.indices.delete('production_data')
print(result)

插入数据

from elasticsearch import Elasticsearch

es = Elasticsearch('192.168.149.96:9200')

action = {
    'perName': '张三',
    'schoolName': '清华',
    'perGrade': 101.0,
    'position': '职务',
    'proMonth': '2020-03',
    'detailedTime': '2020-03-09 00:00:00',
    'projectName': '画框转写',
    'targetOutput': 100.0,
    'actualOutput': 90.0,
    'yieldReachingRate': 0.9,
    'lateness': 1.0,
    'overtime': 1.0,
    'workingHours': 8.0,
    'groupRanking': 3.0,
    'qualityInspection': 2.0,
    'numberOfCustomer': 1.0
}

result = es.index(index="source_data", body=action)
print(result)

批量插入时 action 给成列表， 遍历即可

查询所有数据

from elasticsearch import Elasticsearch

es_con = Elasticsearch([{'host': '192.168.149.96', 'port': 9200}])
data_agg = es_con.search(
    index='base_data',
    size=1000,
    body={
        "query": {
            "match_all": {}
        },
    }
)

print(data_agg, '666666666')

for data in data_agg.get('hits').get('hits'):
    list_data = data.get('_source')
    if '' in list(list_data.values()):
        print(list_data)
        id_ = data.get('_id')
        # es_con.delete(index='base_data', id=id_)
    else:
        pass
        # print(list_data)
