SecureCRT Python

学完python后需要学以致用，但平时还真没有这个环境，也不搞自动化，但语言这玩意必需要用，就拿secureCRT来练手吧，也算是和工作擦点边
对话框加按扭

CONFIRM_REPLACE = """\                                       #为数不多的button判断
Do you want to replace the contents of "%(FILE)s" with the selected text? 

	Yes = overwrite
	No = append
	Cancel = end script"""
message = CONFIRM_REPLACE % { 'FILE' : "filename" }
		prompt = "Replace contents"
		buttons = BUTTON_YESNOCANCEL

		result = crt.Dialog.MessageBox(message, prompt, buttons)
if result == IDYES:
    fileMode = "w"
elif result == IDNO:
    fileMode = "a"
  

 crt.Dialog.Prompt(                                  #超级有用的在用户这获取数据的方式
		"Save selected text to File:",
		"SecureCRT - Save selected text to file",
		"MyFile.txt")
  

获取log文件名在SecureCRT

tab = crt.GetScriptTab()
tab.Session.LogFileName                   
#如果在CRT中设置了log文件名，这个函数可以把它读取出来
#可以直接取到log的文件名

获取系统当前的前缀名

SCRIPT_TAB = crt.GetScriptTab()
rowIndex = SCRIPT_TAB.Screen.CurrentRow
colIndex = SCRIPT_TAB.Screen.CurrentColumn - 1
prompt = SCRIPT_TAB.Screen.Get(rowIndex, 0, rowIndex, colIndex)
#获取当前行，当前列的数据，即该服务器的前缀，与waitfor配套
prompt = prompt.strip()

获取打印值

def CaptureOutputOfCommand(command, prompt):
	if not crt.Session.Connected:
		return "[ERROR: Not Connected.]"
	
	# First, send the command to the remote.
	SCRIPT_TAB.Screen.Send(command + '\r')            
#输入命令 cmmand 然后回车
	
	# Second, wait for the carriage return to be echoed by the remote device. 
	# This allows us to capture only the output of the command, not the line
	# on which the command was issued (which would include the prompt + cmd).
	# If you want to capture the command that was issued, simply comment out
	# the following line of code.
	SCRIPT_TAB.Screen.WaitForString('\r'
#等待命令输完后，服务器给的回应，这样可以不是获取行，而是获取输出
	
	# Now that the command has been sent, use Screen.ReadString to capture
	# all the data that is received up to the point at which the shell
	# prompt appears (the captured data does not include the shell prompt).
	return SCRIPT_TAB.Screen.ReadString(prompt)     
#获取直到prompt出现时的所有数据

屏幕取词

filename = os.path.join(os.path.expanduser('~'), 'output.txt')      #~/output.txt
fp = open(filename, "wb+")
screenrow = crt.Screen.CurrentRow - 1    
readline = crt.Screen.Get(screenrow, 1, screenrow, 20) 
 #把当前行的1~20个字符取出来 
fp.write(readline + os.linesep)                         
#把取出的那一行加行尾符写到文件中

写到excel

import os 
import csv                                               #excel module
fileobj = open(filename, 'wb')
worksheet = csv.writer(fileobj)                                                                
worksheet.writerow(items[:2]) 
fileobj.close(

连接

SSH:
cmd = "/SSH2 /L %s /PASSWORD %s /C 3DES /M MD5 %s" % (user, passwd, host)
crt.Session.Connect(cmd)                                  #ssh -L user password host
Telnet:
crt.Session.Connect("/TELNET 127.0.0.1 2034")            # telnet 127.0.0.1:2034
crt.Session.Connect("/S \"" + session + "\"") 
#如果这个session在CRT里存在，无论是Telnet还是SSH都能连

调试工具 CRT中的print

crt.Dialog.MessageBox("Nothing to save!")
