Question

我遇到了Pyro4的问题，当我尝试连接到我的python服务器时，它从不连接。但据我所知，服务器运行正常。我总是得到 '未连接' 问题。当它没有连接时，我不能对我的对象进行任何python函数调用。

以下是我列出环境中正在运行的内容时的样子

MELO@fence-with-pyro log]pyro4-nsc list
--------START LIST 
Pyro.NameServer --> PYRO:Pyro.NameServer@29.21.14.125:9090
CASA --> PYRO:obj_c74c1737b5894d90b10d64326e70355a@29.21.14.125:36582
--------END LIST 
MELO@fence-with-pyro log]

据我所知，一切看起来都不错。我这样开始CASA：

这是CASA（名称服务器）控制台输出 - （正在运行）

注意：我也试过将NS_HOST设置为ip地址而不是localhost，但它对问题没有影响。

以下是我手动执行步骤时所发生情况的示例

MELO@fence-with-pyro log]python

>>> uri = x.lookup('CASA')

>>> getPyroTraceback()
['None\n']

是什么导致这种情况发生？有没有办法追查这种错误？像更深层次的调试来解决问题？

Answer 1

好吧，我终于把这一切都搞定了。显然“没有联系”是正常的。我发现的是“未连接”状态是可以忽略的。即使是Pyro4示例页面上的仓库示例，如果一个打印仓库页面，仓库也“未连接”。

当我尝试进行Pyro4.proxy（uri）调用时，我一直收到一个未连接的错误
