我正在尝试解决Nagios的插件：send_nrdp.py在这里找到：
http://assets.nagios.com/downloads/nrdp/send_nrdp.py
以下是我的命令行args：
send_nrdp.py --url http://ip.ad.dr.ess/nrdp --token %TOKEN% --hostname testing-monitor --state 0 --output "Test Output" --checktype 1
我不是最熟悉的python或xml - 这对我的工作是必要的，但是被动地监视我们办公室中运行的特定Windows实例。这是send_nrdp.py的实际代码：
#!/usr/bin/env python

使用上面的命令行参数运行，我正在
'Cannot connect to url.'
'junk after document element: line 1, column 40'
我在调用post_data之前打印了xml输出，并且在手动输入到我的mnagios实例的nrdp gui时格式正确。 post_data是否会破坏xml？我注意到如果我打印params，xml的括号被剥离了，但我不确定为什么它没有正确连接。
答案 0 :(得分：0)
令人难以置信的简单回答：结果发现了“垃圾”。只是因为我的网址需要以＆＃39;结尾。通过将其更改为＆＃39; ip.ad.dr.ess / nrdp /＆＃39;;来修复它。抱歉所有的问题
