無法殺死Python腳本

當我的sendShell函數中的所有命令完成執行我的commandfactory列表中的所有命令時，我希望我的腳本停止。我可以成功關閉傳輸連接，但腳本似乎在所有命令運行並且傳輸連接關閉後掛起。任何人都可以幫助我找到一種方法來阻止我的腳本，當所有的命令完成執行和傳輸會話關閉？無法殺死Python腳本

我試圖通過添加while而不是self.transport.close（）到我的輸出循環來殺死腳本。

def process(self): 
      while not self.transport.close(): #Kill script here !!! 
       # Print data when available 
       if self.shell != None and self.shell.recv_ready(): 
        alldata = self.shell.recv(1024) 
        while self.shell.recv_ready(): 
         alldata += self.shell.recv(1024) 
        strdata = alldata.decode("utf8") 
        strdata.rstrip("\r\n") 
        print(strdata, end = ""),

代碼：

import threading, paramiko, re, os 

class ssh: 
    shell = None 
    client = None 
    transport = None 


    def __init__(self, address, username, password): 
     print("Connecting to server on ip", str(address) + ".") 
     self.client = paramiko.client.SSHClient() 
     self.client.set_missing_host_key_policy(paramiko.client.AutoAddPolicy()) 
     self.client.connect(address, username=username, password=password, look_for_keys=False) 
     self.transport = paramiko.Transport((address, 22)) 
     self.transport.connect(username=username, password=password) 

     thread = threading.Thread(target=self.process) 
     thread.daemon = True 
     thread.start() 

    def closeConnection(self): 
     if(self.client != None): 
      self.client.close() 
      self.transport.close() 

    def openShell(self): 
     self.shell = self.client.invoke_shell() 

    def sendShell(self): 
     self.commandfactory = [] 
     print("\nWelcome to Command Factory. Enter Commands you want to execute.\nType \"done\" when you are finished:") 
     while not re.search(r"done.*", str(self.commandfactory)): 
      self.commandfactory.append(input(":")) 
      if self.commandfactory[-1] == "done": 
       del self.commandfactory[-1] 
       break 

     print ("Here are the commands you're going to execute:\n" + str(self.commandfactory)) 
     if(self.shell): 
      self.shell.send("enable" + "\n") 
      self.shell.send("ilovebeer" + "\n") 
      self.shell.send("term len 0" + "\n") 
      for cmdcnt in range(0,len(self.commandfactory)): 
       self.shell.send(self.commandfactory[cmdcnt] + "\n") 
      self.shell.send("exit" + "\n") 
      self.shell.transport.close() 

     else: 
      print("Shell not opened.") 

    def process(self): 
#   global connection 
     while not self.transport.close(): 
      # Print data when available 
      if self.shell != None and self.shell.recv_ready(): 
       alldata = self.shell.recv(1024) 
       while self.shell.recv_ready(): 
        alldata += self.shell.recv(1024) 
       strdata = alldata.decode("utf8") 
       strdata.rstrip("\r\n") 
       print(strdata, end = ""), 

sshUsername = "xxxxx" 
sshPassword = "xxxxxxx" 
sshServer = "xxxxxxxx" 

connection = ssh(sshServer, sshUsername, sshPassword) 
connection.openShell() 

while True: 
    connection.sendShell()

我希望那些不是您發佈在這裏的真實登錄憑證？ – benten

@benten，他們是一個關閉虛擬機測試路由器的登錄，但我刪除，以防萬一有人緊張:) – adrian

刪除'while while True：'。 –

我知道這是老了......但我試圖找出同樣的事情了一會兒。

像其他評論之一說...刪除「而真：」在底部。

此外，您的「全局連接」行被註釋掉。不發表評論。並將其添加到腳本的底部以關閉連接。

connection.closeConnection（connection）
