secureCRT自动登录脚本（python）
由于每次登录都要输入用户名和密码，还有个别设备不能用SSH2，而我又不记得是哪几台？？！！
写个脚本，做个按钮，在Button Bar，New Button，在Action -> Function选Run Script，在Run Script选好脚本路径，自己命名个Label。
给2个版本的示例代码，都是可以直接运行的，一个简单点，但扩展性不好；一个复杂点，但具有很强的扩展性。
版本1：
单个文件，用户名和密码保存在全局变量中。
# $language = "python"
# $interface = "1.0"
#--------------------------------------------------------------------------------------
import os
#--------------------------------------------------------------------------------------
szSSH2UserName = '"asdaf adsf"'
szSSH2Passwd = "adsfqweradsf"
szTelnetUserName = "asdaf adsf"
szTelnetPasswd = szSSH2Passwd
def connectFun():
szHost = crt.Dialog.Prompt("Enter host IP address : ", "Host IP", "", False)
ssh2cmd = "/SSH2 /L %s /PASSWORD %s %s" % (szSSH2UserName, szSSH2Passwd, szHost)
telnetcmd = "/Telnet %s" % (szHost)
oTab = 0
crt.Screen.Synchronous = True
try:
crt.Session.ConnectInTab(ssh2cmd)
oTab = crt.GetActiveTab()
except:
try:
crt.Session.ConnectInTab(telnetcmd)
oTab = crt.GetActiveTab()
oTab.Screen.WaitForString("name")
oTab.Screen.Send(szTelnetUserName + "\r")
oTab.Screen.WaitForString("assword")
oTab.Screen.Send(szTelnetPasswd + "\r")
except:
crt.Dialog.MessageBox(szHost + " Login Failed!","Failed")
return oTab
connectFun()
版本2：
分三个文件，分别是autoConnect.py、connectEnv.py和UserNameAndPassword.txt。（放在同一目录下，且只要在crt中运行autoConnect.py就行了）
- autoConnect.py登录逻辑代码，包括用户名和密码读取。
- connectEnv.py打包了crt所有的API。可参考我重新打包的crt环境类
- UserNameAndPassword.txt保存用户名和密码，第一行是用户名，第二行是密码。

# $interface = "1.0"
