Neo4j无法连接到图形数据库服务器 [英] Neo4j unable to connect to graph database server

问题描述

我正在使用示例脚本连接到neo4j服务器，然后运行查询.但我收到此错误:

I am using an example script to connect to the neo4j server and after that run a query. But I am getting this error:

C:\ cygwin \ lib \ python2.7 \ site-packages \ neo4j \ v1 \ session.py:94: UserWarning:TLS上的Bolt仅在Python 2.7.9+和更高版本中可用 Python 3.3+，因此通讯不安全

C:\cygwin\lib\python2.7\site-packages\neo4j\v1\session.py:94: UserWarning: Bolt over TLS is only available in Python 2.7.9+ and Python 3.3+ so communications are not secure

socket.gaierror:[Errno 11004] getaddrinfo失败

socket.gaierror: [Errno 11004] getaddrinfo failed

示例代码:

from neo4j.v1 import GraphDatabase, basic_auth
driver = GraphDatabase.driver("bolt://http://localhost:7474",             auth=basic_auth("neo4j", "neo"))
session = driver.session()
result = session.run("MATCH (label:OFFICER)-[r]->()  WHERE label.NAME = 'Prinza Limited' RETURN label,r")
print result
session.close()

推荐答案

该驱动程序仅支持Bolt，因此无法使用http.

The driver only support Bolt, so no http possible.

您的连接uri混合了两个协议，请更改为:

Your connection uri mixes the two protocols, change to this :

driver = GraphDatabase.driver("bolt://localhost",auth=basic_auth("neo4j", "neo"))
session = driver.session()

通常，仅按照存储库自述文件中的示例进行操作，就不应在连接uri中使用http: https://github.com/neo4j/neo4j-python-driver#example-usage

Normally, by just following the example in the repository readme, you shouldn't have the http in the connection uri : https://github.com/neo4j/neo4j-python-driver#example-usage
