Python的Telnetlib read

本文介绍了Python的Telnetlib read_until'＃'或'＆GT;'，多发串的决心？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 if (tn.read_until('>')): action1 else: action2

或

if (tn.read_until() == '>'): action1 else: action2

我只想 read_until（）来检查哪些所需的字符串是第一位的，并做不同的动作。或者是有任何等价的方法？

I just want the read_until() to check which desired String comes first, and do different actions. Or is there any equivalent ways?

推荐答案

看的文档。阅读，直到希望的有望的字符串作为位置参数和一个可选的超时。我会做这样的：

Look at the docs. Read until wants the expected string as a positional argument and an optional timeout. I would do it like this:

>>> try: ... response = tn.read_until(">", timeout=120) #or whatever timeout you choose. ... except EOFError as e: ... print "Connection closed: %s" % e >>> if ">" in response: ... action1 ... else: ... action2

如果你愿意，你可以使用多个不同的字符 read_some（）

If you want multiple different characters you can use read_some()

>>> while True: #really you should set some sort of a timeout here. ... r = tn.read_some() ... if any(x in r for x in ["#", ">"]): ... break
