python - SecurityError: 无法建立到“EOF 违反协议 (_ssl.c:841)”的安全连接

Question

我正在尝试连接到 Neo4j，但我不断收到此错误。我试过

from neo4j.v1 import GraphDatabase
driver = GraphDatabase.driver(uri="bolt://localhost:7687", auth=("neo4j", "12345"))

但是当我尝试连接时出现此错误

SecurityError: 无法建立到“EOF 违反协议 (_ssl.c:841)”的安全连接

当我输入http://localhost:7474/browser/时，我可以连接到浏览器

这是完整的错误日志：

Answer 1

我为可能有同样问题的人找到了解决方案。您需要添加encrypted=False.

代替

from neo4j.v1 import GraphDatabase
driver = GraphDatabase.driver(uri="bolt://localhost:7687", auth=("neo4j", "12345"))

它应该是：

driver = GraphDatabase.driver(uri="bolt://localhost:7687", auth=("neo4j", "12345"), encrypted=False)

希望这会对某人有所帮助
