因此，我在带有 rexster 和 orientdb 的 mac-osx 上使用 python3.2 和灯泡。详情:
orientdb - 从他们的页面标准下载
~/workspace/orientdb-community-1.7-rc1
运行服务器，./bin/server.sh
数据库 - orientdb数据库 ~/databases/orientdb/dev-db-01
rexster - 来自 github 的标准结帐 git clone git://github.com/tinkerpop/rexster.wiki.git ~/workspace/
配置/rexster.xml:
...
<graph>
<graph-enabled>true</graph-enabled>
<graph-name>dev-db-01</graph-name>
<graph-type>orientgraph</graph-type>
<graph-location>local:*<path to...>*/databases/orientdb/dev-db-01</graph-location>
<properties>
<username>admin</username>
<password>admin</password>
</properties>
<extensions>
<allows>
<allow>tp:gremlin</allow>
</allows>
</extensions>
</graph>
...
Python代码:
from bulbs.rexster import Graph
from bulbs.config import Config
config = Config("http://localhost:8182/dev-db-01/", username="admin", password="admin")
g = Graph(config)
问题:

我认为 是 python 代码配置中的 url 不正确(我尝试了各种变体)。但我不知道；如果我保持 rexster.xml 不变并只使用标准图形构造函数，它就会工作；但这是一个问题，因为它没有将节点添加到我想要的 orientdb 数据库，dev-db-01，而是将它们放在默认数据库中。因此，为了确保我连接到正确的数据库，我禁用了除我创建的 orientdb 数据库之外的所有数据库。
如何让它正确连接？
最佳答案
URL 应在路径中包含/graphs/:
http://localhost:8182/graphs/dev-db-01/
