elasticsearch的简单实践

ndlli

　　Elasticsearch，一款非常优秀的分布式搜索程序，下面是一些简单的应用方法的封装，希望对大家有所帮助
　　#!/usr/bin/env python
#encoding:utf-8
from elasticsearch import Elasticsearch
import os
import configparser as cparser
from builtins import int
from framework.logger import Logger
from utils.rcpUtils import rcpUtils
　　'''========读取config.ini文件中redis配置========'''
base_dir = str(os.path.dirname(os.path.dirname(file)))
　　file_path = base_dir + "\config\config.ini"
cf = cparser.ConfigParser()
cf.read(file_path)
host = cf.get("uatesconf", "host")
port = cf.get("uatesconf", 'port')
logger = Logger(logger="esUtils").getlog()
　　'''===========封装es基本操作============='''
　　rcp = rcpUtils()
　　class esUtils:

def __init__(self):
'''初始化，获得es的连接'''
try:
self.es = Elasticsearch([{'host':host,'port':port}])
logger.info('connect to es sevrver %s:%s successfully!'%(host,port))
except BaseException as e:
logger.exception("Failed to get the es Connection,please check the configuration:%s" %e)
def isClusterUP(self):
'''检测服务是否起来'''
return self.es.ping()
def getServerInfo(self):
'''获取服务的一些基本信息,如版本号，集群名称等'''
return self.es.info()
def isExist_table(self,table):
'''判断表(索引)是否在es中存在'''
if self.es.indices.exists(index=table) is True:
return True
else:
return False
def getESInfo(self,index,_id):
'''精确查询es表中的数据,返回的字典,用于风控检查接口发送后,到es的订单表等场景'''
logger.info('Search %s contains %s.' %(index,_id))
params = {
'query': {
'match': {
'_id': _id
}
}
}
_searched = self.es.search(index=index, doc_type=index, body=params)
return _searched['hits']['hits'][0]['_source']

es = esUtils()
index = 't_order'
