python調用neo4j的存儲過程APOC

1.安裝好neo4j數據庫

2.安裝apoc

3.python調用apoc

from py2neo import Graph
from neo4j import GraphDatabase


class Neo4jSearch():
    def __init__(self):
        self.driver = GraphDatabase.driver("bolt://localhost:7687", auth=("neo4j", "123456"))
    def call_proc(self):
        '''
        neo4 4.1版本上調用apoc
        :return:
        '''
        with self.driver.session() as session:
            # cypher = "CALL apoc.help('dijkstra')"
            # cypher = "CALL apoc.algo.community(25,null,'partition','X','OUTGOING','weight',10000)"
            # cypher = " return apoc.number.format(12345.67) as value"
            # cypher = '''return apoc.date.parseAsZonedDateTime('2012-12-23 23:59:59','yyyy-MM-dd HH:mm:ss', 'UTC')'''
            # cypher = '''return apoc.date.parse('2012-12-23','ms|s|m|h|d','yyyy-MM-dd')'''
            # cypher = "CALL dbms.procedures() YIELD name WHERE name CONTAINS 'shortest' RETURN *"
            cypher = "return  apoc.date.parse('2012-12-23','d','yyyy-MM-dd')"
            data = session.run(cypher).data()
            print(data)
            session.close()
            self.driver.close()

if __name__ == "__main__":
    Neo4jSearch().call_proc()

適用於neo4j 3.5版本及以上，通過python調用apoc.

注意：neo4j圖數據與apoc版本一致。
