python - 如何通过带灯泡的 rexster 连接到 orientdb graph？

Question

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？

Answer 1

URL 应在路径中包含/graphs/:

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