Question

所以，我在mac-osx上使用python3.2和灯泡，使用rexster和orientdb。详细说明：

orientdb - 从他们的页面标准下载

〜/工作区/ orientdb社区-1.7-RC1

运行服务器./bin/server.sh

数据库 - orientdb数据库〜/数据库/ orientdb的/ 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，它就可以工作;但那是一个问题，因为它没有向我想要的orientdb数据库添加节点，dev-db-01，它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，除了我创建的orientdb数据库之外，我禁用了所有数据库。

如何正确连接？

网址应包含路径中的/ graphs /：

http://localhost:8182/graphs/dev-db-01/

如何通过带灯泡的rexster连接到orientdb图？
